§ 3 Investigation

(1) Points of evidence for the existence of an end-of-life load exist at an old location, in particular when land has been dealt with on land over a prolonged period of time or in a significant quantity of pollutants, and the respective operating, management and management activities are or procedures or disturbances of the intended use of such substances in the soil, which are not insignificant. In the case of deposits, such indications are given, in particular, where the nature of the holding or the date of closure suggests that waste has not been properly treated, stored or deposited. (2) Paragraph 1, first sentence, shall apply: for harmful soil changes accordingly. In addition to paragraph 1, there are indications of the existence of a harmful change in soil, in particular by means of general or specific references to:

1.: the entry of pollutants over a longer period of time, and in a significant quantity by air or water, or by the application of significant amounts of waste or waste water to soils,
2.: a significant release of naturally increased levels of harmful substances in soils,
3.: increased pollutant content in food or fodder plants at the site,
4.: the leakage of water with considerable amounts of pollutants from soils or deposits,
5.: Substantial soil deposits and deposits by water or wind.

It shall also include findings on the basis of general studies or experience gained from comparative situations, in particular on the spread of pollutants. (3) The evidence referred to in paragraphs 1 or 2 shall be included in the suspect area, or (4) Concrete indications that justify the reasonable suspicion of a harmful soil change or an old load (§ 9 para. 2 sentence 1 of the Federal Soil Protection Act), are usually available if investigations are carried out by a Exceeding of test values will result or if an overrun of test values is to be expected on the basis of an evaluation in accordance with § 4 (3). If there is sufficient suspicion within the meaning of sentence 1 or due to other findings, a detailed examination shall be carried out. (5) In the case of detailed investigations, it is also to be determined whether or not from spatially limited enrichment of polluting substances within a suspected area or suspected area, and whether and how a delineation of non-polluted areas is required. A detailed examination may be carried out if the hazards arising from harmful soil changes or contaminated sites, major disadvantages or significant nuisances, after the competent authority has been established by simple means (6) Where there is evidence of the spread of volatile pollutants from a suspect area, either on the basis of local conditions or on the basis of the results of ground-air surveys; or Suspect area in buildings shall be subject to an investigation of the The tasks and powers of other authorities shall remain unaffected. (7) In the context of investigation orders pursuant to § 9 (2) sentence 1 of the Federal Soil Protection Act (Federal Soil Protection Act), recurrent investigations of the emission of harmful substances shall also be carried out. (8) The requirements for the investigation of soils, soil materials and other materials, as well as soil air, landfill gas and leachate, shall be determined in accordance with Annex 1.

§ 4 Evaluation

(1) The results of the guidance studies shall be assessed in accordance with this Regulation in accordance with the circumstances of the individual case, in particular on the basis of test values. (2) The content or concentration of a pollutant shall be assessed. below the relevant test value in Annex 2, the suspicion of a harmful soil change or a contaminated site has been removed. If a test value as set out in Annex 2, point 3, is exceeded at the site of the sampling, it shall be determined on a case-by-case basis whether the pollutant concentration in the leachate at the site of the assessment exceeds the test value. Measures within the meaning of Section 2 (7) or (8) of the Federal Soil Protection Act may already be necessary if, in individual cases, all unfavourable circumstances adopted in the derivation of a test value in accordance with Annex 2 meet and the salary or the concentration of a pollutant is slightly above the respective test value in Annex 2. (3) Sicker water prognosis is to be used to assess the risks to groundwater from suspected areas or suspected sites of old-load. create. Where a seepage water forecast is based on studies in accordance with Annex 1, point 3.3, it shall in particular be estimated and assessed in particular cases to what extent it is to be expected that the concentration of pollutants in the leachate water will be the test value at the site of the assessment. exceeds. The location of the assessment shall be the area of transition from the unsaturated to the saturated zone. (4) The results of the detailed investigation shall be carried out in accordance with this Regulation, taking into account the circumstances of the case, and in particular on the basis of: Measures to assess the extent to which measures are required pursuant to § 2 (7) or (8) of the Federal Soil Protection Act. (5) Insofar as no test or measure value is set in this Regulation for a pollutant, the evaluation shall be carried out in accordance with the following criteria: the methods and standards used to derive the relevant values in Annex 2 Please note. These are published in the Federal Gazette No 161a of 28 August 1999. (6) If there is a more sensitive use of the predominant use within a suspected area or an area suspected of having an old-load suspicion, the use of these areas is (7) In the individual case, findings from groundwater investigations are available, these are to be found in the evaluation with regard to pollutant entries into the groundwater. consideration. If increased concentrations of pollutants in leachate or other polluting substances can only be expected to have low pollutant concentrations and only locally limited concentrations of pollutants in water, this is the case when it comes to the test to take account of the proportionality of investigative and remedial measures. Water legislation remains unaffected. (8) A harmful soil change does not exist in soils with naturally elevated levels of pollutants solely on the basis of these contents, insofar as these substances are not caused by effects on the soil in the soil. have been or are being released to a significant extent. A comparison of these contents with the pollutant contents determined in the individual case can be included in the hazard assessment in the case of soils with increased pollutant contents which are caused by large areas of settlement.

Unofficial table of contents

§ 5 Sanation measures, protection and restriction measures

(1) Decontamination measures shall be suitable for remediation if they are based on technically and economically feasible procedures which appear to be suitable for the environmentally sound disposal or reduction of pollutants. . Account should also be taken of the consequences of the intervention, in particular for soils and waters. Once a decontamination measure has been completed, it is necessary to substantiate the achievement of the refurbishment target with the competent authority. (2) If pollutants are to be removed in accordance with § 4 (5) of the Federal Soil Protection Act and there is a pre-load, the To demand, in principle, the services which it would have to provide without any preload. The previously existing uses of the land are to be restored. (3) Safety measures are suitable for refurbishment if they ensure that the pollutants in the soil or contaminated sites do not permanently contain any harmful substances. Hazards, significant disadvantages or major annoyances for the individual or the general public are created. In this case, the danger potential of the pollutants remaining in the soil and their transformation products must be taken into account. A subsequent restoration of the securing effect in the sense of the sentence 1 must be possible. The effectiveness of security measures must be documented and permanently monitored in relation to the competent authority. (4) As a safeguard measure, a suitable covering of harmful modified soils or contaminated sites with a soil layer shall also be considered as a safeguard measure; or (5) Areas used for agricultural and forestry purposes are, in the case of harmful soil changes or contaminated sites, above all protection and restriction measures by means of adaptations to the use and management of soils. as well as changes in soil characteristics. Records shall be kept of the protection and restriction measures taken. Agreement shall be reached with the competent agricultural authority. Article 17 (3) of the Federal Soil Protection Act remains unaffected. (6) Should the material be removed, expelled or treated in the context of the restoration in the area of the same harmful soil change or used load or within the area of a material for The requirements of § 4 (3) of the German Federal Soil Protection Act are to be complied with again or in the event of a binding declaration of a binding declaration of reorganisation or restoving.

§ 8 Security of harmful soil changes due to soil erosion by water

(1) The existence of a harmful soil change due to soil erosion by water shall be considered, in particular, if:

1.: large amounts of soil material have been swamped from an erosion surface due to surface discharge, and
2.: other soil yields as specified in paragraph 1 are to be expected.

(2) indications of the existence of a harmful soil change due to soil erosion by water arise, in particular, when areas situated outside the supposed erosion area are polluted by water-off soil material; (3) If there are indications as referred to in paragraph 2, it is necessary to determine whether there is a harmful soil change due to soil erosion by water. Where it is possible to determine which erosion surface may be attributed to soil precoat and that considerable quantities of soil material have been washed off, it shall be examined whether the conditions set out in paragraph 1 (2) are met. Evaluation of the results of the investigations is carried out on a case-by-case basis, taking into account the specificities of Further land yields are to be expected if:

1.: in recent years, considerable quantities of soil material have been washed out of the same erosion surface, or
2.: it is clear from the location data and the data on the long-term precipitation of the area that over a period of ten years, with sufficient probability, the re-entry of land as referred to in paragraph 1 (1) shall be applied to: is expected.

(5) The further requirements for the examination and evaluation of areas where there is a suspicion of harmful soil change due to soil erosion by water are set out in Annex 4. (6) The erosion surface shall be determined by the following: In accordance with § 17 of the Federal Soil Protection Act, the competent advisory body is to be given the opportunity to recommend suitable erosion-reducing measures for the use of the erosion surface in the context of the consultation. In the case of orders, agreement shall be reached with the competent agricultural authority.

Seventh Part
Precautionary measures against the emergence of harmful soil changes

Unofficial table of contents

§ 9 Concern of harmful soil changes

(1) The emergence of harmful soil changes in accordance with § 7 of the Federal Soil Protection Act is usually to be obtained if:

1.: measuring levels of pollutants in the soil which exceed the precautionary values referred to in Annex 2, point 4, or
2.: a significant enrichment of other harmful substances, which are particularly likely to cause harmful soil changes due to their carcinogenic, mutagenic, reproductive or toxic properties.

§ 17 (1) of the Federal Soil Protection Act remains unaffected. (2) In the case of soils with naturally increased pollutant contents, there is concern about the emergence of harmful soil changes if the precautionary values are exceeded in accordance with Annex 2, point 4 only, if a significant release of harmful substances or additional entries can be expected by the adverse effects on the soil functions, which are expected in accordance with § 7 sentence 1 of the Federal Soil Protection Act. (3) Paragraph 2 applies accordingly in the case of soils Increased pollutant content due to large-scale settlement conditions. Unofficial table of contents

§ 10 precautionary requirements

(1) If the conditions of § 9 (1), first sentence, no. 1, para. 2 or 3 are fulfilled, the provisions of § 7 of the Federal Soil Protection Act must be taken to cause further action by him on the property and its scope of action. To avoid or effectively reduce pollutant entries, to the extent that this is also proportionate to the purpose of the use of the land. This also includes technical arrangements for installations or procedures and measures for the investigation and monitoring of soils. For the purpose of the investigation, Annex 1 shall apply.

Annex 1

(Fundstelle: BGBl. I 1999, 1561-1574)

: Requirements for sampling, analysis and quality assurance in the investigation

This Annex shall apply to the investigation of soils, soil materials and other materials found in the soil or on the soils of suspected or old-load suspected areas, or to be fitted and put in place, and of ground air.
In the case of old-load suspected deposits, the scope of the investigation and the sampling, in particular as regards the investigations into landfill gas, volatile pollutants, deposited waste and the transfer of pollutants into the Groundwater, according to the requirements of the individual case.
For the purposes of this Annex, the state of procedures and methods shall be the state of development of advanced methods and methods which make it possible to ensure their practical suitability for the purposes of the above studies. Findings on such methods and methods and on their application will be compiled by a selected group of experts from the federal and state governments as well as those affected in consultation with the Länder, the Federal Ministry for the Environment, Nature conservation and reactor safety are convened.

1.: Scope of investigation and required knowledge

The studies referred to in Article 3 of this Regulation relate to the paths of action for which there is a suspicion of danger on the basis of the information available on a case-by-case basis. When determining the scope of the investigation, the results of the collection, in particular the knowledge or reasonable suspicions about the occurrence of certain pollutants and their distribution, the current use and the use according to § 4 Paragraph 4 of the Federal Soil Protection Act and the consequent protection needs as well as the other local circumstances which are subject to appraisal of the assessment. The E DIN ISO 10381-3: 02.96 is to be observed. For occupational health and safety, reference is made to the ZH 1/183: 04.97.
In the investigation into the effective path of soil-human beings are used as usages

-: Children's Playgrounds
-: Residential areas
-: Park and leisure facilities
-: Industrial and commercial land

and in the investigation into the effective path of the soil-useful plant, the uses

-: Arable land, farm garden
-: Grassland

.
In the case of investigations into the effective path of soil groundwater, it is not possible to distinguish between the type of land use.

1.1: Orientating Investigation

In particular, it is also intended to focus on the identification and assessment of the scope of partial areas with different levels of pollutant contents, in particular for the purpose of determining and assessing the extent of suspected sites and old-load suspects.
In the case of old-load suspected old deposits, investigations of landfill gas and of highly volatile pollutants as well as investigations, in particular with regard to the transfer of pollutants into the ground water, are to be carried out.
If, at the request of the competent authority, the ground or surface water is to be carried out at the request of the competent authority in the case of suspected areas, this shall be the case for the determination of the extent and the conduct of the orienting study for Soil or seepage water tests should be taken into account.
In the case of suspicions, it is not possible to resort to existing soil maps or if there is no suitable soil-related information, in the context of the orientation study, a good-term mapping or ground contact shall be carried out at the site. the sampling on the basis of the ground-based caring instructions, 4. Edition, adjusted reprint 1996, to the extent necessary for risk assessment.
The investigation requirements for soils and soil materials shall apply in accordance with § § 9, 10 and 12.

1.2: Detailed investigation

In the detailed examination, in addition to the facts referred to in § 3 (5) and (6) of this Regulation, the conditions of exposure relevant to the paths of action, in particular the mobile or mobile nature of the different paths of action, shall also be subject to the detailed examination. mobilisable units of the pollutant content. It is also intended to determine whether risks arise from spatially limited enrichment of pollutants within a suspected area or an area suspected of old-load suspicion, and whether and how a delimitation of uncontaminated areas is required.

2.: Sampling

The procedure for sampling is based, in particular, on the actual paths of action, the size of the area, the vertical and horizontal distribution of pollutants, as well as the present, which are presumed to be based on the results of the detection. for planning purposes and the earlier use. The requirements referred to in points 2.1 to 2.3 shall be taken into account. The procedure for taking samples shall be justified and documented. The requirements of occupational safety and health are to be observed.
Examination surfaces should be divided into suitable faces for sampling. The division shall be based on a different hazard suspicion, different land use, terrain or soil characteristics as well as abnormalities, such as a different vegetation development, or on the basis of Findings from the collection take place.

2.1: Sampling planning for soil investigations-determination of the sampling points and testing depths

If the spatial distribution of the pollutants is to be determined, the surface or partial surface to be examined should in principle be sampled in a representative way with the aid of a grid. To the extent that a hypothesis on the spatial distribution of pollutants can be derived from prior knowledge, in the case of old-load suspected old sites, in particular according to the results of the detection, it shall be used in the determination of the sampling points and of the grid. For the determination of sampling points, results from an appropriate on-site analysis can also be used.
Suspected pollutant accumulations are to be tested in a targeted manner. The test shall be carried out, in particular with regard to the number and the spatial arrangement of the sampling points, in such a way that the suspicion of danger is clarified, a possible danger is assessed and a spatial delimitation of pollutant accumulations takes place. can.
The sampling depths referred to in Table 1 shall be used as a basis for the determination of the depth of sampling for the soil-human and soil-useful plants for the study of inorganic and low-volatility organic pollutants.

1) Contact area for oral and dermal pollutant absorption, additionally 0-2 cm in case of relevance of the inhalative recording path. 2) 0-35 cm: average thickness of applied soil layers; at the same time max. depth attainable by children. 3) Machining horizon. 4) Main root area.

Soils are to be sampled as far as possible. The basis for the determination of the horizontal sequence is the ground-based caring instructions of the Geological Landesämter (AG Bodenkunde, 4. Edition, 1994). Soils that have been destroyed in the subsoil are to be sampled in layers (see Table 1). The plies or horizons, which can be represented by taking a sample, is usually 30 cm. More powerful horizons or layers are to be divided if necessary. In addition to Table 1, the depth of sampling must be taken into account, for which special precautions must be taken in the use to be taken into account in accordance with Section 4 (4) of the Federal Soil Protection Act. The reasons for different probation depths are to be documented.
In the case of sampling, the following shall be taken into consideration with regard to the operating paths:

2.1.1: Real-life path of soil-human

As part of the determination of the sampling points and the sampling depth, investigations into the conditions of exposure present in the individual case shall also be carried out, in particular by means of:

-: the actual use of the area (type, frequency, duration),
-: the accessibility of the area,
-: the sealing of the surface and of the growth,
-: the possibility of inhalation of soil particles,
-: the relevance of further action paths.

The uppermost two centimetres of the soil are decisive for the assessment of the hazards due to the inhalation of soil particles. Such pollutants, for which the inhalative path according to the diversion standards in accordance with Article 4 (5) of this Regulation has proven to be decisive for the determination of the test value, are significant in terms of inhalation. By means of restoring samples, it must be ensured that the pollutant content in the fine-grain fraction of up to 63 mym relevant for the formation of dust can be analyzed separately, if necessary.
If, on the basis of existing knowledge, it is to be assumed that the pollutants in the assessment-relevant soil layer are distributed approximately uniformly over a surface area, can be on areas up to 10,000 square meters for 1,000 square meters each, but at least 3 Faces, a mixed sample is taken. The mixing sample is to be obtained from 15 to 25 individual samples of a test depth. In the case of areas under 500 square metres, as well as in house gardens or other gardens of corresponding use, a division can be dispensed with. For areas of more than 10,000 square meters, at least 10 faces are to be tested.

2.1.2: Real-life path of soil-crop

In the case of agricultural soils with an approximately uniform soil quality and distribution of pollutants, land up to 10 hectares is to be considered as a rule for 1 hectare each, but at least 3 partial areas. Mix sample in accordance with the sampling depths. In areas of less than 5,000 square meters, a division can be dispensed with. For areas larger than 10 hectares, however, at least 10 faces shall be tested. Sampling is carried out in accordance with the rules of sampling on agricultural soils (E DIN ISO 10381-1: 02.96, E DIN ISO 10381-4: 02.96) by 15 to 25 individual stitches per sub-area, which are combined to form a mixed sample in each case.
In commercial gardens, sampling is usually carried out by taking a mixed sample for each sampling depth, and, moreover, on the basis of the rules of sampling on arable land.
For the suitability of devices for sampling, E DIN ISO 10381-2: 02.96 is authoritative.

2.1.3: Ground Floor-ground water

In order to determine the vertical pollutant distribution, the soil-ground water is to be sampled below a presumed pollutant enrichment or a conspicuous soil body in order to determine the vertical distribution of pollutants. The test is carried out in a horizontal or layer-specific manner. Samples from deep intervals up to a maximum of 1 m may be taken in the subsoil. In well-founded cases, the summary is of a grainy soil horizons or -layers up to a maximum of 1 m depth interval allowed. Conspicuity shall be assessed and, where appropriate, tested separately. The depth of sampling should be reduced if it becomes apparent that in the case of a through-bore of water-damp layers in the subsoil, a contamination of the ground water resulting from this is to be obtained. If the drilling of water-damp layers is necessary, special precautionary measures must be taken. DIN 4021: 10.90 is authoritative for the suitability of devices for sampling.

2.2: Sampling planning ground air

Sampling is carried out according to VDI guideline 3865, sheets 1 and 2.

2.3: Sampling planning for abrasied and excavated soil material

Sampling is carried out in accordance with DIN 52101: 03.88 or according to DIN EN 932-1: 11.96.

2.4: Sampling
2.4.1: Soils, soil materials and other materials

The required sample quantity is determined in accordance with DIN 18123: 11.96 according to the size grain and must be sufficient to ensure the laboratory examination and, if necessary, the provision of restoring samples after appropriate sample pretreatment. A vote with the investigative body should be carried out.
Coarse materials (materials > 2 mm) and foreign materials, which may contain harmful substances or which they can adhere to, can be taken from the entire sample quantity and must be supplied separately to the laboratory examination. Their mass fraction of the sampled soil horizon or the layer unit must be identified and documented.
For the removal of soil, soil material and other materials, methods are to be used which are listed in DIN 4021: 10.90 and E DIN ISO 10381-2: 02.96. In the course of the selection procedure, the required sample quantity and the structure of the substrate must be taken into account in addition to the information contained in the standard.

2.4.2: Ground air

VDI guideline 3865, sheet 2, applies to the extraction of soil air samples.

2.5: Sample conserving, transport and storage

For the selection of sample vessels as well as for sample conservation, transport and storage of samples, the appropriate regulations shall be complied with in the examination regulations in accordance with point 3.1.3, Tables 3 to 7. In the absence of such regulations, E DIN ISO 10381-1: 02.96 and DIN EN ISO 5667-3: 04.96 must be observed.
The transport of the soil samples for the investigation of organic pollutants and their storage is carried out in accordance with E DIN ISO 14507: 02.96.

3.: Investigation procedure
3.1: Investigation procedures for soils, soil material and other materials
3.1.1: Sample selection and pre-treatment

In the case of stepped examinations, it is necessary to decide on a case-by-case basis the sequence in which samples obtained in the field are to be analysed, and whether, if appropriate, A summary of several samples is also expedient. The decision and its reasons are to be documented.
The sample pre-treatment, including the drying of the sample material, is carried out for the determination of physico-chemical properties (point 3.1.3, Table 3) and the determination of inorganic pollutants (point 3.1.3, Table 4) according to DIN ISO 11464: 12.96. EDIN ISO 14507: 02.96 is to be used for organic pollutants.
If soil, soil material and other materials (in particular slag and construction rubble) require separation into coarse and fine particles, this has a sieve with a mesh size of 2 mm in the fractions < = 2 mm (fine fraction) and > 2 mm (Grobanteil) grain diameter to be effected. Clumps are to be crushed, but low-stable aggregates (e.g. carbonate, iron concretions, and Bims) should not be broken up. Both fractions shall be weighed, described and documented, and their dry matter content shall be determined. The fine fraction shall be homogenized and examined. If there is evidence of an increased pollutant content of the fraction > 2 mm, this fraction must be obtained and, after pre-comminution and homogenization, also to be examined. Foreign materials contained in the sample material shall be examined separately, if necessary, and shall be taken into account in the evaluation.
Representative parts of the samples taken in the field shall be retained as rehearsals. The nature and extent of the provision shall be agreed upon in accordance with the requirements of the individual case.

Recovery of the soil saturation extract: For preparation, the soil sample is slowly added in a polyethylene vessel so much bidistilled water that it is completely moistened. The required amount of water for pre-humidification is dependent on the soil and should correspond approximately to the field capacity. In the case of sandy rehearsals, the 25%, in the case of loam/slippage samples of approx. 35% and in the case of tonous samples of approx. 40% of the weight of the soil was dry. The amount of water added shall be determined gravimetrically and recorded. The sample is thoroughly mixed and is allowed to stand for 24 hours at 5 ° C. under evaporation protection. For the production of the soil saturation extract, the pre-moistened soil material is transferred into centrifuge cups. Bidistilled water is slowly added with continuous stirring until the yield point has been reached (formation of a glossy surface and disintegration of a spatula notch). In the case of clay samples, it is necessary to wait for 15 minutes until the swelling is complete and, if necessary, to give up water. The amount of water added is determined gravimetrically and the soil paste is stirred with a glass rod. The soil paste is to be stored in a refrigerator or room at 5 ° C under evaporation protection in order to adjust the equilibrium for 24 h. The soil/water ratio is calculated from the initial weight of air-dry soil and two-times water addition. In this case, the water content of the air-dry sample must be determined separately at an Aliquot (drying at 105 degrees C to constant weight) and taken into account by calculation. Refrigerated centrifuge for 30 min. The supernatant solution is decanted and membrane filtered by means of a negative pressure in order to separate suspended particles into previously weighed polyethylene bottles. The amount of filtrate shall be determined gravimetrically. The solutions can be stabilized by adding 10 parts by volume of nitric acid (c= 5 mol/l), the addition of acid to be taken into account in the evaluation of measurement results and the preparation of calibration solutions.

(2)

Filtration step: A pressure filtration unit for membrane filters (142 mm diameter, media-carrying parts made of PTFE) is used with a membrane filter with a pore width of 0.45 mym. When using deviating devices, the volume to be filtered must be changed in accordance with the filter area; the ratio of the filtration volume and the filter area must be maintained. After shaking, the suspension is approx. Allow to stand for 15 min to sedimentation of the coarser particles. The supernatant liquid is to be decanted to the greatest possible extent in the centrifuge cup. The centrifugation is carried out for 30 minutes with 2,000 g. Thereafter, the supernatant liquid is decanted to the greatest possible extent in the membrane pressure filtration apparatus. After 5 min of pressureless filtration, a pressure of 1 bar is applied for acceleration of the filtration. If after 15 minutes less than two thirds of the eluate passed the filter, the pressure is increased to 2 bar. If necessary, the pressure is increased to 3.5 bar after a further 30 minutes. The filtration is continued until the entire supernatal of the centrifugation has passed through the filter. If the filtration is still incomplete after 120 minutes, it is terminated and further worked up with the incomplete filtrate.

3.2: Investigation of soil air

The investigation of soil air is carried out according to VDI guideline 3865 sheets 2 and 3.

3.3: Method of estimating the substance entry from suspected or old-load-suspected areas into the groundwater

The substance concentrations and loads in the seepage water and the pollutant input into the groundwater in the transition zone from the unsaturated to the water-saturated ground zone (site of the assessment) can be estimated, unless favourable circumstances provide a representative sample of seepage water at the site of the assessment.
This estimate can approximate

-: by means of conclusions or back-accounts from investigations in the groundwater flow, taking into account the concentration of substances in the stream of groundwater, dilution, pollutant behaviour in the unsaturated and saturated soil zones, and the pollutant inventories in the soil,
-: on the basis of in-situ investigations, or
-: on the basis of material investigations in the laboratory (elution, extraction), in the case of inorganic substances in particular the elution with water, according to Table 2

shall also be carried out using mass transport models.
The substance concentrations in the seepage water can be found at the site of the sampling

-: in the case of inorganic pollutants, are equivalent to the results of the soil saturation extract; estimations using analytical results according to Table 6 and other elution processes (e.g. DIN 19730 or DIN 38414-4) are if the equivalence of the results is ensured, in particular by reference to these results, to the soil saturation extract; results in accordance with DIN 38414-4: 10.84 can only be used if the filtration according to point 3.1.2 of this the Regulation was implemented;
-: For organic substances from column tests of the samples removed, taking into account the location conditions at the point of removal, in particular with regard to the contact time, with methods according to Table 7 are determined.

The analytical results of the investigation of seepage water, groundwater, extracts and eluates as well as soil samples shall be indicated by means of the respective examination procedure. The estimation of the seepage water quality and rates for the transition range from the unsaturated zone to the water-saturated zone based on this assessment shall be explained in detail and justified.
In particular, the assessment shall be carried out using methods which have been successfully applied in the case of practical questions. To this end, it is necessary to meet in individual cases a review of the subject.
In addition, the following instructions should be taken into consideration:
If, in the individual case of a harmful soil change or used load, an access of acidic leachate waters, an access of solubilizers or a change in the redox potential should be expected, appropriate further extraction procedures should be used.
In the estimation of the pollutant input in the transition region from the unsaturated to the saturated zone, the degradation and retention effect of the unsaturated zone must in particular be taken into consideration. In particular, the following criteria are decisive:

-: Ground water flow distance,
-: soil type,
-: Content of organic matter (humus content),
-: ph value,
-: Groundwater reformation rate/Sicker water rate,
-: Mobility and degradability of substances.

The influence of these factors on the material retention in the unsaturated zone is estimated on the basis of generally available scientific findings and experience for the respective site. The use of material transport models can also be expedient.
In the case of direct testing and investigation of leachate water, the weather-related dynamics must be taken into account in the evaluation of the measured substance concentrations.

3.2: Application of test values
a): The test values apply to the transition range from the unsaturated to the water-saturated ground zone (site of assessment). The site of the sampling of soil does not necessarily correspond to the site of the assessment of groundwater.
b): In assessing whether it is expected that the test values for leachate water should be exceeded at the site of the assessment, the changes in pollutant concentrations in leachate during passage through the unsaturated soil zone and the Groundwater flow distances and their fluctuations should be taken into account.
c): In the case of old deposits, the estimation of the concentrations of pollutants in leachate due to material investigations due to inhomogeneities of the deposited waste is generally not appropriate. The same applies to old sites with particularly non-uniform pollutant distribution. In these cases, an estimation of the pollutant concentrations in the leachate can be carried out by means of conclusions or back-calculation from downstream measurements in the ground water, taking into account in particular also the substance concentration in the flow.
d): In so far as the concentrations of pollutants in the seepage water can be measured directly, the sampling shall be carried out at the site of the assessment for groundwater.
e): As far as harmful soil changes and contaminated sites lie in the water-saturated soil zone, they are assessed in terms of a danger to groundwater according to water legislation.
f): The geogenic background situation of the respective groundwater region should be taken into account in the application of the test values.

The measures to be taken for this purpose shall be presented in the light of the combination of measures and the accompanying measures.
The test shall in particular:

-: the pollutant, soil, material and location-specific suitability of the procedures,
-: the technical feasibility,
-: the amount of time required,
-: the effectiveness with regard to the reorganisation target,
-: an estimate of costs and the ratio of costs and effectiveness,
-: the effects on the persons concerned within the meaning of § 12 sentence 1 of the Federal soil protection act and on the environment,
-: the requirement of authorisations;
-: the creation, recovery and disposal of waste,
-: occupational health and safety;
-: the duration of the measures and their monitoring possibilities;
-: the requirements of the aftercare and
-: the remedy

.
The test shall be carried out using existing data, in particular from investigations in accordance with § 3 of this Regulation, as well as on the basis of other factual knowledge. Insofar as such information is not sufficient, in particular for the secure demarcation of contaminated areas or for the assessment of the suitability of refurbishment procedures in individual cases, additional investigations shall be carried out in order to verify the suitability of a method ,
The results of the examination and the policy concept which is to be presented accordingly are to be presented.

Annex 4

Fundstelle: BGBl. I 1999, 1582

: Requirements for the investigation and evaluation of areas suspected of harmful soil change due to soil erosion by water

1.

Application

This Annex is applied in accordance with § 8 of the application in the investigation of areas where there is a suspicion of a harmful soil change due to soil erosion by water.

2.: Investigation and evaluation

If there is evidence of the existence of a harmful soil change due to soil erosion by water, it must first be considered that:

a): whether significant quantities of soil material have been swamped from the erosion surface, and
b): on which erosion areas and which polluters the soil precoat is due to.

Indications for an identification of the erosion surface are the result, in particular, of clearly visible transfer points of soil material from the erosion surface to the areas situated outside the erosion surface and affected by soil material. Further information is obtained from the presence of clearly visible erosion forms on the erosion surface. In the case of the test referred to in point (a), it may be necessary for the quantity of the soil to be washed off from a roofing area during an erosion event or in the event of erosion events which have occurred at a distance of a maximum of a few weeks in succession from a suspiaion area. , This can be done with the help of the "Kartieranleitung zur Capture Current Erosion Forms" (DVWK 1996).
For the estimation of the probability of re-entry of land in accordance with § 8 (1), special area-specific statistical evaluations of long-time rainfall records of the German Weather Service are to be used. For this purpose, erosion prognosis models can also be used as aids to the extent that they are proven to be suitable, the amounts of soil quenched from the erosion surfaces in the case of concretely occurring erosion events with sufficient accuracy. ,
The conditions for the expectation of further land orders pursuant to § 8 (1) (2) are generally fulfilled if, within the last ten years, substantial quantities of soil material from the same erosion surface have been swamped in at least one further case. .
