§ 3 Investigation

(1) There is evidence of the existence of an old load at an old location, in particular if land has been dealt with over a prolonged period of time or in a significant quantity of pollutants, and the operation, management or method of operation or disturbances of the intended operation are not insignificant entries of such land Substances in the soil suggest. In the case of deposits, these indications are given, in particular, where the nature of the holding or the date of closure suggests that waste has not been handled, stored or deposited in a proper manner.(2) Paragraph 1, first sentence, shall apply mutatily to harmful soil changes. In addition to paragraph 1, there are indications of the existence of a harmful soil change, in particular by means of general or concrete references to
1.
the entry of pollutants over a longer period of time and in a significant amount over the air or water or by applying considerable amounts of waste to waste or waste water on soils,
2.
a significant release of natural elevated levels of harmful substances in soils,
3.
increased pollutant contents in food or fodder plants at the site,
4.
the escape of water with Significant amounts of pollutants from soils or deposits,
5.
substantial soil deposits and deposits by water or wind.
To be included in this Also findings based on general studies or empirical values from comparative situations, in particular for the spread of pollutants.If there are indications as referred to in paragraph 1 or 2, the suspected area shall be subject to an orientation examination after the recording has been recorded.(4) Concrete indications that justify the reasonable suspicion of a harmful soil change or legacy load (Section 9 (2) sentence 1 of the Federal Soil Protection Act) are generally available if investigations result in exceeding of test values or if an assessment in accordance with Section 4 (3) is to be expected to exceed test values. If there is sufficient suspicion within the meaning of sentence 1 or on the basis of other findings, a detailed examination shall be carried out.(5) In the case of detailed investigations, it should also be established whether there are dangers arising from spatially limited enrichment of pollutants within a suspected area or suspected area of old load, and whether and how a delineation of non-polluting substances is Areas are offered. 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 can be removed or removed.(6) In so far as there is evidence of the spread of volatile pollutants from a suspected area or an area suspected to be of old-load in buildings, as a result of the local conditions or the results of ground-air investigations, a inspection of indoor air; the tasks and powers of other authorities shall remain unaffected.(7) In accordance with § 9 (2) sentence 1 of the Federal Soil Protection Act (Federal Soil Protection Act), recurrent investigations of the propagation of harmful substances and of the relevant circumstances shall also be considered.(8) The requirements for the investigation of soils, soil materials and other materials, as well as soil air, landfill gas and leachate, are also determined in accordance with Annex 1. Non-official table of contents

§ 4 Evaluation

(1) The results of the orienting studies are subject to compliance with this Regulation To assess the circumstances of the individual case, in particular on the basis of test values.(2) The content or concentration of a pollutant below the relevant test value in Annex 2 shall be cleared in so far as the suspicion of a harmful soil change or contaminated load has been eliminated. If a test value in accordance with 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 connection with 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 relevant test value in Annex 2.(3) A Sickerwater forecast shall be drawn up for the assessment of the risks to groundwater from suspected areas or areas suspected of having old-load suspicion. Where a Sickerwater 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 seepage water shall be subject to the test value at the site of the assessment. exceeds. The site of the assessment is the area of transition from the unsaturated to the saturated zone.(4) The results of the detailed investigation shall be assessed in accordance with this Regulation in accordance with the circumstances of the individual case, in particular on the basis of measures of measures, in order to assess the extent to which measures pursuant to § 2 (7) or (8) of the Federal soil protection law is required.(5) Where no test or measure value is fixed for a pollutant in this Regulation, the methods and standards used to derive the corresponding values in Annex 2 shall be taken into account for the evaluation. These are published in the Federal Gazette No. 161a of the 28th Published in August 1999.(6) If a more sensitive use differs from the predominant use within a suspected area or an old-load suspicious area, these sub-areas shall be determined according to the scales laid down for their use. assess.(7) In individual cases, findings from groundwater investigations shall be taken into account in the assessment with regard to pollutant entries in groundwater. 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, in so far as these substances have not been released to a significant extent by effects on the soil; or . A comparison of these contents with the pollutant contents determined in individual cases can be included in the hazard assessment in the case of soils with increased pollutant contents.

§ 5 Remediation measures, protection and restriction measures

(1) Decontamination measures are suitable for refurbishment if they are based on technically and economically feasible methods which are suitable for the environment-friendly environment. To ensure the elimination or reduction of the pollutants. Account must 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 confirm that the restoration target has been reached with the competent authority.(2) If pollutants are to be eliminated in accordance with Section 4 (5) of the Federal Soil Protection Act and there is a preload, the person who is subject to the charge shall, in principle, demand the services which he would have to provide without any preloading. The previously existing uses of the land should be restored.(3) Safety measures shall be appropriate for remediation if they ensure that the remaining pollutants in the soil or contaminated sites do not permanently pose any risks, significant disadvantages or significant nuisances to the individual or to the Generality arise. 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 precautionary measure, a suitable covering of harmful modified soils or contaminated sites with a soil layer or a sealing is also possible.(5) Areas used for agricultural and forestry purposes are subject to protection and restriction measures, in particular by adapting the use and management of soils, and changes in the land used in the case of harmful soil changes or contaminated sites. Soil quality is possible. Records shall be kept of the protection and restriction measures taken. Agreement shall be reached with the competent agricultural authority. § 17 (3) of the Federal Soil Protection Act remains unaffected.(6) If the material is to be expelled, ejected or treated in the course of the restoration in the area of the same harmful soil change or contaminated land or within the area of a recaptised plan of remediation, reinstated or introduced or migrated, the requirements of § 4 (3) of the Federal Soil Protection Act are to be fulfilled.

2.
a significant enrichment of other pollutants, which is due to their Carcinogenic, mutagenic, toxic to reproduction or toxic properties are particularly suitable for causing harmful soil changes.
§ 17 (1) of the Federal Soil Protection Act remains unaffected.(2) In the case of soils with naturally increased levels of pollution, there is concern at 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 pollutants or pollutants is found to be harmful to the soil. Additional entries can be expected from the adverse effects on the soil functions provided by § 7 sentence 1 of the Federal Soil Protection Act (Federal Soil Protection Act).(3) Paragraph 2 applies correspondingly in the case of soils with increased pollutant contents due to the large area of settlement.

In the case of old-load suspected old deposits, investigations of landfill gas and volatile pollutants as well as of volatile pollutants are generally considered. to carry out investigations, in particular with regard to the transfer of pollutants into groundwater.
In the case of suspected areas or areas suspected of being contaminated with old load, investigations of the reason or of the ground at the request of the competent authority shall be carried out. Surface water must be taken into account when determining the extent and the flow of the orienting examination for soil or seepage water studies.
In the case of suspicions, it cannot rely on existing soil maps. , or if there is no suitable soil-related information, an indicative mapping or ground address at the site of the sampling on the basis of the ground information shall be carried out within the framework of the indicative investigation.

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 delineation of non-polluted areas is required.
2.
sampling
The sampling procedure depends in particular on the individual case the area size, the expected vertical and horizontal distribution of pollutants due to the results of the detection, as well as the current, the permissible and the earlier use. The requirements referred to in points 2.1 to 2.3 shall be taken into account. The procedure for sampling shall be justified and documented. The requirements of occupational health and safety are to be observed.
Investigation areas are to 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 Insights from the capture are done.
2.1
Sample sampling planning for soil investigations-definition of sampling points and Probation Depth
the spatial distribution of the pollutants is to be determined, the area or sub-area to be examined is to be sampled in principle with the aid of a raster. 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.

are as to be sampled in a horizontal way. 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 sampling depths are to be documented.
When taking the sample, the following should be noted with respect to the mode of action:

Reaction Path Floor- Human
the framework 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 about
-
the actual use of the area (type, frequency, duration),
-
the accessibility of the surface,
-
the sealing of the surface and over the growth,
-
the possibility of inhalation of soil particles,
-
the relevance of further Action paths.
To assess the hazards of inhalation of soil particles, the topmost two centimetres of the soil are decisive. 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 rehearsals, 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.
Pollutants in the assessment-relevant soil layer are distributed approximately uniformly over a surface area, can be taken from areas up to 10,000 square meters for 1,000 square meters each, but at least 3 partial faces, a mixed sample. 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 surfaces over 10,000 square meters, at least 10 faces are to be tested.
2.1.2
Reaction Path Floor-
agriculturally gartenstructurally used soils with approximately uniform soil characteristics and pollutant distribution on areas of up to 10 hectares as a rule for 1 hectare each, but at least 3 partial areas a mixed sample according to the testing depths from the table. In the case of areas of less than 5,000 square metres, a division can be dispensed with. For areas larger than 10 hectares, however, at least 10 faces shall be tested. Sampling is carried out according to 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 single stitches per face, which are combined to form a mixed sample in each case.
In The use of the sample is usually carried out by taking a mixed sample for each sample depth and in accordance with the rules of sampling on arable land.
For the suitability of equipment for sampling, the sample is usually taken from the sample. E DIN ISO 10381-2: 02.96 authoritative.
2.1.3
Reaction path ground-
bottom-ground water path is the Determination of the vertical pollutant distribution to test the unsaturated soil zone up to below a presumed pollutant enrichment or a conspicuous soil body. 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. For the suitability of devices for sampling, DIN 4021: 10.90 is authoritative.

Extraction 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 humidified. 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 are to be stabilized by adding 10% by volume of nitric acid (c= 5 mol/l), taking into account the addition of acid in the analysis of measurement results and the preparation of calibration solutions.
(2)
filtration step: Use is made of a pressure filtration unit for membrane filters (142 mm diameter, media-carrying parts made of PTFE) with a membrane filter with 0.45 mym pore width. 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 is to 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 through 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 will be broken off and further worked on with the incomplete filtrate.

Method to estimate the substance entry from suspected or old-load suspicious areas to the
The concentrations and loads of substances in the seepage water and the input of pollutants into the groundwater in the transition zone from the unsaturated to the water-saturated ground zone (the site of the assessment) can be estimated, unless favorable circumstances allow for representative testing of seepage water at the site of assessment.
This estimate can approximate
-
by means of conclusions or returns from investigations in the groundwater flow, taking into account the concentration of substances in the groundwater flow, the dilution, the Pollutant behaviour in the unsaturated and saturated soil zone as well as pollutant inventories in the soil,
-
based on 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 the table 2
can also be done using fabric transport models.
The substance concentrations in the seepage water can be found at the site of sampling
-
for inorganic pollutants, equivalent to the results of the Soil saturation extract; estimates based on analytical results according to Table 6 and Other elution processes (e.g. DIN 19730 or DIN 38414-4) are permissible if the equivalence of the results is ensured, in particular by reference to these results on the soil saturation extract; results according to DIN 38414-4: 10.84 shall be used only if the filtration has been carried out in accordance with point 3.1.2 of this Regulation;
-
for organic substances from column tests of samples taken under Consideration of the location conditions at the point of removal, in particular with regard to the contact time, with the method according to Table 7.
The analytical results of the investigation of leachate water, groundwater, extracts and eluates as well as of the analysis of the site conditions are determined by the following methods: 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 must be explained and explained in
. which have been successfully applied to practical questions. For this purpose, the following instructions should be taken into consideration in individual cases.
In addition, the following instructions should be noted:
If in the individual case of a harmful soil change or contaminated soil an access of acidic leachate waters, an entry of Redeeming agents or a change in the redox potential should be expected, appropriate further extraction methods should be used.
In the estimation of the pollutant input in the transition zone from the unsaturated to the saturated zone shall, in particular, take account of the deplete and retention effect of the unsaturated zone. In particular, the following criteria are relevant:
-
ground water flurp distance,
-
Bodenart,
-
organic matter content (humus content),
-
phvalue,
-
groundwater reformation rate/seepage water rate,
-
The mobility and degradability of the substances.
The influence of these factors on the retention of substances in the unsaturated zone is due to the general scientific background Findings and experiences for the respective location are estimated. The use of material transport models can also be expedient.
In the case of direct testing and examination of leachate water, the weather-related dynamics must be taken into account in the evaluation of the measured substance concentrations.

Application
This appendix is applicable in accordance with § 8 Application Investigation of areas where there is a suspicion of harmful soil degradation due to soil erosion by water.
2.
Investigation and Evaluation
Evidence of the presence of a harmful Soil erosion due to soil erosion by water, so first check,
a)
whether significant Quantities of soil material from the erosion surface have been washed and
b)
on which erosion surfaces and on which polluters the soil precoat can be attributed
Information for the identification of the erosion surface is given above all by clearly visible transfer points of soil material from the erosion surface to the outside of the erosion surface and by soil material affected areas. 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 roof 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 from a roof 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), especially 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 demonstrably suitable for the erosion of the soil with sufficient accuracy in the case of concretely occurring erosion events from the erosion surfaces. ,
The conditions for the expectation of further land yields in accordance with § 8 (1) No. 2 are generally fulfilled if, within the last ten years, at least in one further case, significant amounts of soil material from the same erosion surface area are met. have been swamped.
