Second part on the investigation and assessment of suspected areas and old load suspicious areas § 3 requirements study (1) evidence of the existence of a legacy at an Altstandort in particular, if was gone on land over a period of time or in significant quantities with pollutants and the respective operation, management or procedures, or errors of the operation as directed suspect not insignificant entries of such substances in the soil can be. These clues are were especially given the type of operation or the date of the closure of the suspected suggest that waste is not properly treated, stored or deposited in waste deposits.
(2) paragraph 1 sentence 1 applies to harmful soil changes according to. Evidence for the existence of a harmful soil changes result in an entry of pollutants over a longer period and in considerable amount through the air or water or through an application of substantial loads of waste in addition to paragraph 1, in particular by General or specific instructions on 1 or a significant release nature caused waste water on floors, 2. increased levels of pollutants in soil , 3. increased pollutant levels in food or fodder crops at the site, 4. the leakage of water with significant loads of pollutants from soil or waste deposits, 5. considerable Bodenabträge and remove by water or wind.
Also the findings on the basis of general studies or empirical values from comparing situations in particular to the spread of pollutants are to be included.
(3) there are indications pursuant to paragraph 1 or 2, the suspected area or old load suspicious area to undergo first an exploratory investigation after the acquisition.
(4) concrete evidence substantiating the probable cause of a harmful soil changes or legacy (§ 9 para 2 sentence 1 of the Federal Soil Protection Act), are generally, if tests show a test values are exceeded or if on the basis of an assessment according to § 4 para 3 exceeding of test values can be expected. Is a probable cause within the meaning of sentence 1 or on the basis of other findings, a detailed examination should be performed.
(5) in the case of detailed investigations should also be found, if risks arising from spatially limited enrichment of pollutants within a suspected area or old load suspicious area and whether and how a distinction not contaminated areas is available. A detailed examination may be waived if you from harmful soil changes or contaminated sites can be repelled dangers, significant disadvantages or considerable nuisances from the identification of the competent authority with simple means or otherwise eliminated.
(6) where on the basis of local conditions or according to the results of soil air investigations exist, evidence for the spread of volatile contaminants from a suspected area or old load suspicious area in building a study of indoor air should be; the tasks and powers of other authorities remain unaffected.
(7) within the framework examination regulations according to § 9 para 2 sentence 1 of the Federal soil protection act are also recurrent investigations of pollutant dispersion and this relevant circumstances into account.
(8) the requirements for the investigation of soils, soil material and other materials, as well as by ground air, landfill gas and leachate determine otherwise pursuant to annex 1.
§ To assess 4 review (1) that are results of exploratory analyses under this regulation in accordance with the circumstances of the individual case, in particular on the basis of test values.
(2) the content or the concentration of a pollutant below the corresponding test in annex 2, are suspected of harmful soil changes or legacy is eliminated so far. If a test value is exceeded pursuant to annex 2 No. 3 at the place of sampling, is to determine whether the pollutant concentration in the leachate in the place of the assessment exceeds the value in the individual case. Measures within the meaning of § 2 paragraph 7 or 8 of the Federal soil protection act can be already required if in individual cases to meet all the unfavourable circumstances assumed in the derivation of a test value referred to in annex 2 and the salary or the concentration of a pollutant slightly above the respective value of testing in annex 2.
(3) to assess the risks posed by sites or old load suspicious areas for groundwater is a leachate prognosis to create. A leachate prognosis supported no. 3.3 investigations pursuant to annex 1, is to assess in each individual case in particular and to assess to what extent it is expected that the pollutant concentration in the leachate exceeds the value in the location of the assessment. The assessment is the area of transition from the unsaturated in the saturated zone.
(4) the results of the detailed examination are under this regulation in accordance with the circumstances of the case, in particular on the basis of measure values, to evaluate to what extent measures are required according to section 2 paragraph 7 or 8 of the Federal soil protection act.
(5) where no test or measure value is set in this regulation for a pollutant, you are for the assessment to derive the corresponding values in annex 2 consulted methods and standards to observe. These are published by 28 August 1999 in the Federal Gazette No. 161a.
(6) these areas are more sensitive use differs from the prevailing use exists within a suspected area or old load suspicious area on part surface, according to the standards set for your use each to evaluate.
(7) groundwater research evidence in some cases, are taken into account when evaluating in terms of pollutants in groundwater. If anticipating increased pollutant concentrations in the leachate or other pollutant losses permanently low pollutant load and limited locally increased concentrations of pollutants in water, this fact when assessing the proportionality of investigations and remedial measures to take into account. Statutory provisions shall remain unaffected.
(8) a harmful soil changes is no for floors with nature due to the increased amounts of pollutants alone on the basis of this content, as far as these substances were not released from agents on the ground in substantial or are. A comparison of these levels with the pollutant content determined in the individual case can be included in the risk assessment in soils containing large areas due to the settlement increased pollutant levels.
Part three requirements for the rehabilitation of harmful soil changes and legacies article 5, protection and restriction measures (1) decontamination measures are suitable for rehabilitation if they are based on technically and economically feasible methods, their practical suitability for the environmentally compatible disposal or reduction of pollutants secured the appear. The consequences of the intervention in particular for soils and waters are taken into account. The goal of the renovation to the competent authority is to prove after a decontamination measure.
(2) if pollutants to eliminate are according to § 4 paragraph 5 the Federal soil protection act and a preload, are the services to require, that he would have without providing preload of the subject. The previously existing uses of the land to be restored.
(3) precautionary measures are suitable for renovation, if they ensure that the remaining in the soil or contaminated sites pollution permanently no dangers, caused considerable disadvantages or considerable nuisances for individuals or the general public. Here it has to be potential danger of pollutants remaining in the soil and their transformation products. A subsequent recovery of the backup action within the meaning of sentence 1 must be possible. The effectiveness of safeguards is to prove to the competent authority and to monitor permanently.
(4) as a precautionary measure is also a suitable cover harmful modified soil or contaminated with a layer of soil or a seal into consideration.
(5) on land and forestry, especially protective and restrictive measures harmful soil changes or contaminated sites come through adjustments to the use and management of soils, as well as changes in soil characteristics into consideration. Records to lead are about the taken protective and restrictive measures. With the competent agricultural trade agreement is to bring about. Section 17, paragraph 3, of the Federal soil protection act shall remain unaffected.
(6) to slid off, excavated or treated material in part of the renovation in the same harmful soil changes or legacy or within the area of a reorganization plan for binding back on - or introduced or transferred, the requirements are according to § 4 section 3 of the Federal soil protection act to fulfill.
Fourth part of supplementary rules for contaminated sites section 6 is rehabilitation investigation and remediation planning (1) remediation investigations in particular also to consider what measures, a restructuring within the meaning of § 4 para 3 of the Federal soil protection act can be achieved, to what extent changes in the soil after the renovation remains, and what legal, organizational and financial requirements for the implementation of measures of importance.
(2) in establishing a rehabilitation plan, the measures are 3 of the Federal soil protection act text and drawings completely to represent no. According to section 13, paragraph 1, sentence 1. In the recovery plan is to demonstrate that the planned measures are suited, permanently shut to avoid significant disadvantages or considerable nuisances for individuals or the general public. To represent are in particular the impact of the measures on the environment and the estimated costs, as well as the necessary approvals, even if a mandatory rehabilitation plan may not include these according to § 13 para 6 of the Federal soil protection act.
(3) the requirements for an investigation of rehabilitation and a restructuring plan given in addition Annex 3. fifth part exceptions section 7 exceptions on harmful soil changes and legacies, after finding the competent authority risks can be significant disadvantages or considerable nuisances easily repelled or otherwise removed, is section 6 no application.
Part six supplementary provisions for security of harmful soil changes caused by soil erosion through water section 8 security of harmful soil changes caused by soil erosion by water
(1) by the existence of a harmful soil changes on the basis of soil erosion by water is to be especially when 1 by surface runoff were washed significant amounts of soil material from an erosion area and 2 additional Bodenabträge referred to in paragraph 1 are to be expected.
(2) evidence of the existence of harmful soil changes caused by soil erosion through water arise in particular when outside the supposed erosion surface areas were freighted by floor material stranded off.
(3) there are indications referred to in paragraph 2, is to determine whether there is a harmful soil changes on the basis of soil erosion by water. It is possible to determine on which erosion surface the floor wash-off can be attributed and that substantial amounts of soil material were washed off from this, is to check whether the conditions of in paragraph 1 are met no. 2.
(4) the evaluation of the results of the investigations is case-based, taking into account the special features of the site. More Bodenabträge are to be expected, if 1 in the past few years several significant amounts of soil material from same erosion surface were washed or 2. results from the location data and the data about the long-term precipitation conditions of the area, that no. 1 is in a period of ten years with reasonable probability with the further entry of Bodenabträgen referred to in paragraph 1.
(5) the additional requirements for the examination and evaluation of surfaces, which is the suspected of harmful soil changes caused by soil erosion by water, are in annex 4.
(6) if the erosion area used for agricultural purposes, is to give the opportunity of the Federal soil protection act, to recommend appropriate advice erosion reduction measures for the use of the erosion area under the competent advice pursuant to clause 17. For arrangements, agreement with the agricultural trade authority is to bring about.
Seventh part of prevention of the emergence of harmful soil changes section 9 concern of harmful soil changes (1) which is usually used to obtain 1 pollutant levels in the soil are measured, harmful soil changes according to § 7 of the Federal soil protection act which the precautionary levels after 2 No. 4 exceed annex, or 2 is a considerable enrichment of other pollutants which are suitable on the basis of their carcinogenic, mutagenic, reproductive toxicity or toxic properties in particular , to bring about harmful soil changes.
Section 17, paragraph 1, of the Federal soil protection act shall remain unaffected.
(2) in soils with natural-caused increased pollutant levels concern of the emergence of soil changes 2 No. 4 more harmful when exceeding the precautionary levels pursuant to annex only exist if a significant release of pollutants or additional entries by the after section 7, sentence 1, of the Federal soil protection act can expect adverse effects on soil functions required.
(3) paragraph 2 shall apply accordingly with soils containing large areas due to the settlement increased pollutant levels.
§ 10 precautionary requirements (1) are no. 1, 2 or 3 the requirements of § 9 para 1 sentence 1, according to § 7 of the Federal soil protection act to make required arrangements, has further by him on the land and its sphere of influence to avoid caused pollution or to reduce, as far as this also with regard to the purpose of use of the land is relatively effective. These include also technical measures to equipment or procedures, as well as measures for investigation and monitoring of soils. The investigation applies to annex 1 in accordance with.
(2) records of pollutants within the meaning of § 9 para 1 sentence 1 are no. 2, for which no pension values are set, to limit as far as technically possible and economically justifiable in accordance with paragraph 1. This particularly applies to the substances which are according to the Ordinance on hazardous substances classified as carcinogenic, mutagenic or toxic to reproduction classified.
§ 11 are allowed additional load (1) in annex 2 No. 4.1 exceeded set precautionary levels for one pollutant, is 2 No. as far as an additional load to the height in annex 5 fixed annual freight of the pollutant that is allowed. While the impact on the ground through air and water, as well as through direct entries must be observed.
(2) as far as no. 5 set permissible additional load when a pollutant is exceeded in annex 2, the geogenic or large-scale settlement-related impact in individual cases are taken into account.
(3) that does not determine No. 5 established freight in annex 2 within the meaning of § 3 para 3 sentence 2 of the Federal soil protection act, which charges by the operation of a plant not as a causal contribution to the emergence of harmful soil changes to be.
§ 12 requirements for the application and materials on or in the soil (1) for the production of durchwurzelbaren soil layer in and on floors only soil material as well as dredging may according to DIN 19731 (issue 5/98) and mixtures of ground material with such waste, which fulfill the material quality requirements pursuant to section 11 of the circulatory economic law and section 8 of the regulations until 1 June 2012 current recycling and waste management Act, as well as the sewage sludge Ordinance , up and be.

Article 14 entry into force this regulation enters into force on the day after the announcement.
Concluding formula the Federal Council has approved.
Annex 1 (reference: Federal Law Gazette I 1999, 1561 - 1574) requirements for the sampling, analysis, and quality assurance in the investigation this Annex apply to the investigation of soils, soil materials and other materials, which in the soil or on the grounds of suspected areas or old load suspicious areas occur, or are intended for the construction and placement, as well as by ground air.
At old load suspicious old deposits, the scope of analysis and sampling, particularly with regard to the investigations on landfill gas, volatile pollutants deposited waste and of the transfer of pollutants in groundwater, set according to the requirements of the individual case.
The purposes of this annex the level of processes and methods which development of advanced procedures and methods, secured their practical suitability to the above mentioned studies which makes is. Findings about such procedures and methods and their application are put together by a select group of professionals from federal and countries, as well as of the persons concerned in consultation with the countries convened by the Federal Ministry for environment, nature conservation and nuclear safety.
1 scope of the analysis and required level of knowledge relate investigations pursuant to section 3 of this regulation to the effect paths for the due to the information provided in the case of suspicion of a risk resulting. The scope of the investigation, the results of the acquisition, in particular the knowledge or reasonable guesses about the occurrence of certain pollutants and their distribution, to take into account the present use and the use in accordance with § 4 para 4 of the Federal soil protection act and the resulting protection needs and other assessment significant local conditions are. The E is ISO 10381-3: 02.96 note. 1 is to the health and safety on the ZH / 183: 04.97 pointed out.
During the investigation to the ground - effect path, man are crop as uses - children's play area - residential - parks and recreation - industrial and commercial properties and the investigation to the ground - effect path to distinguish the uses – agriculture, Garden - green land.
In investigations of the ground - effect path, groundwater is not to differ according to the type of land use.
1.1 exploratory investigation exploratory investigations of suspected areas and old load suspected contaminated sites should be aligned in particular also on the determination and the assessment of the scope of sections with different high pollutant levels.
When old load suspicious old deposits usually testing of landfill gas and volatile pollutants, as well as investigations in particular with regard to the transfer of pollutants in groundwater should be.
Investigations of ground or surface water sites or old load suspicious areas on request of the competent authorities must be carried out this is taken into account in defining scope and trace of the exploratory study for ground or leachate tests.
Can be resorted at sites mapping of the soil not on existing or no suitable soil-related information is available, a pedological mapping or floor speech at the place of sampling on the basis of the Subcommission Kartieren Guide, 4th Edition, corrected reprint to perform the exploratory survey in 1996, in extent, is needed for the risk assessment.
The examination regulations for floors and floor materials for the articles 9, 10 and 12 shall apply mutatis mutandis.
1.2 detailed examination at a detailed examination should be solved next to the under § 3 para 5 and 6 of this regulation the relevant to the action paths exposure conditions, in particular the significant for the different paths of the effect mobile or mobilisable shares of pollutant levels, situations referred to. It should also be noted whether hazards arising from spatially limited enrichment of pollutants within a suspected area or old load suspicious area and whether and how a distinction not contaminated areas is available.
2. sampling the sampling approach is aimed in particular after the effect paths touched in some cases, the size, the vertical and horizontal contaminant distribution suspected on the basis of the results of acquisition as well as the current, the planning law allowed and the previous use. The requirements to be observed in paragraphs 2.1 to 2.3 are. The procedure for sampling is to justify and document. The requirements of the occupational health and safety must be observed.
Investigation areas intended to be included in appropriate areas for sampling. The Division shall be made on the basis of a different suspicion of danger, a different land use, the terrain or soil conditions and abnormalities, such as a different vegetation development, or on the basis of findings from the acquisition.
2.1 Probennahmeplanung for soil analysis - determination of compounds and be sampling depth should be determined the spatial distribution of pollutants, is basically using a grid representative to be sampled the surface to be examined or sub-plot. As far as a hypothesis concerning the spatial distribution of pollutants can be derived from prior knowledge, at old load suspected contaminated sites in particular according to the results of the acquisition, this is when determining the compounds and of the grid. Also results from a suitable before site analysis can be used for the determination of compounds.
Suspected pollutant enhancements are targeted to be sampled. The sampling is particularly with regard to the number and spatial arrangement of the compounds, so to make, that clarified the suspicion of danger, evaluated a possible danger and a spatial delimitation of pollutant enrichment can take place.
In determining the loading sampling depths for the ground - effect paths to man and soil - crop for the study on inorganic and heavy volatile organic pollutants which are stated in table 1 above be sampling depths.
Table 1 Nutzungsorientierte be probung depth investigations on the ground - effect path man and soil - crop effect path use be sampling depth ground - man children's play area, residential area 0-10 cm 1) 10-35 cm 2) parks and recreation area 0-10 cm 1) industrial and commercial land 0-10 cm 1) soil - crop agriculture, Garden 0-30 cm 3) 30-60 cm grassland 0-10 cm 4) 10-30 cm 1) contact area for oral and dermal absorption of contaminants , in addition 0-2 cm at the relevance of the inhaled recording path.
2) 0-35 cm: average thickness of applied layers of soil; at the same time maximum children accessible depth.
(3) editing horizons.
(4) main root zone.
Floors are possible horizon to be sampled. Basis for calculating the sequence of horizons is the soil science Kartieren guide of the geological country offices (AG soil science, 4th Edition, 1994). Soils disturbed to the underbody are layers to be sampled (see table 1). The layer or horizon thickness, which can be represented by a specimen is more powerful horizons typically 30 cm. or layers are, if necessary, to divide. Be sampling depth is taken into account for the according to § 4 para 4 of the Federal soil protection act to include use special precautions to be taken in addition to table 1. The reasons for dissenting be sampling depth should be documented.
When sampling is to consider the following with respect to the effect track: 2.1.1 effect path ground - Man In the context of determining the compounds and be sampling depth should be, made in particular on - the actual use of the area (type, frequency, duration), - also investigations into the exposure conditions present in each individual case the accessibility of the area, - the seal of the area and about the nursery.
Possibility of inhalation absorption of soil particles, the relevance of another action paths.
The top two centimetres of the soil are decisive for the assessment of hazards of the inhalative intake of soil particles. Inhalation are important sources of such pollutants for which the inhalation path has proven this regulation according to the discharge standards in accordance with § 4 paragraph 5 as decisive for the determination of the value of the test. Samples is to ensure that the pollutant content in the grain group, relevant to the formation of dust can be mym, if necessary, separately analyzed up to 63.
Is due to present evidence to assume that the pollutants in the relevant assessment soil layer are roughly equally distributed over an area, can on surfaces up to 10,000 square metres for each 1,000 square meters, or at least of 3 areas, a mixed sample be taken. The composite sample should be obtained from 15 to 25 samples of be sampling depth. Under 500 square metres, as well as in home gardens or other gardens of appropriate use can be omitted on a Division. For surfaces over 10,000 square meters to at least 10 sites sampled are.
2.1.2 effect path soil - crop in agriculture including horticultural used soils with almost uniform soil and contaminant distribution to areas up to 10 hectares for each ha-1, but at least a composite sample according to be sampling depths are taken from 3 areas. Surfaces under 5,000 square meters can be omitted on a Division. For areas greater than 10 hectares to at least 10 sites sampled are. The sampling is done 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 punctures per sub-plot, which merged into a composite sample each.
In kitchen gardens, sampling is done usually by taking a plot-related mixing sample for each be sampling depth and otherwise in accordance with the rules of sampling on arable land.
For the suitability of equipment for sampling is DIN ISO 10381-2: 02.96 decisive.
2.1.3 effect path ground - ground water in the ground - effect path is ground water to determine the vertical distribution of pollutant to sampled the unsaturated soil zone below a suspected pollutant concentration or of striking the ground body.

(1) extraction of soil saturation extract:
To prepare slowly so much bi-distilled water is admitted the soil sample in a polyethylene container that it is completely soaked. The required amount of water to the before humidification depends on the soil type and should resemble the field capacity. Sandy samples assumes 25% in loamy silt-sample of approximately 35% and clay samples of approximately 40% of the weight of air-dry soil. The amount of water to is gravimetrically to capture and record. The sample is well mixed and evaporation protection 24 h at 5 degrees C is left to stand.
For the production of soil saturation extract, the pre-moistened soil material is transformed into a centrifuge. BI-distilled water is added slowly, stirring constantly, until the yield point is reached (formation of a shiny surface and Zerfließen a trowel notch). Clay samples must be waited 15 min until the swelling and, if necessary, given water. The amount of water to is gravimetrically recorded and mixed the ground paste with a glass rod. The ground paste is to the equilibrium to be kept 24 hours in the refrigerator or-raum at 5 degrees C under evaporation protection.
The soil/water ratio is calculated from the weight of air-dry soil and double water addition. The water content of the air dry sample one is aliquot separately to capture (drying at 105 degrees C to constant weight) and calculated to take into account.
Is obtaining soil solution of equilibrium centrifugation in a refrigerated centrifuge for 30 min. The excess solution is decanted and filtered to separate suspended particles in previously balanced polyethylene wide neck bottles using vacuum membrane. The quantity of filtrate is to determine gravimetrically. The solutions are adding 10 volume nitric acid (c = 5 mol/l) to stabilise, taking into account the addition of acid in the evaluation of measurement results and the preparation of calibration solutions.
(2) filtration step: a unit of pressure filtration is used for membrane filter (142 mm diameter, media-leading parts made of PTFE) with a 0.45 of mym pore size membrane filter. When using different devices, the volume filter according to the filter surface is to change; the ratio of filtrierendem volume and filter surface must be observed.
After the shaking, the suspension is to let stand 15 minutes to the sedimentation of the coarser particles. The excess fluid is to decant as much as possible in the centrifuge. The centrifugation is carried out for 30 min with 2,000 g. This is followed by the largely complete decant of the excess fluid in the membrane pressure filtration equipment. After 5 min Filtration free to, a pressure of 1 bar is applied to accelerate the filtration. After 15 min less than two-thirds of the eluate passing the filter, the pressure is increased to 2 bar. If necessary, the pressure is increased to 3.5 bar after another 30 min. The filtration continues, until the entire projection of the centrifugation has passed the filter. The filtration is still incomplete after 120 min she is interrupted and continued with the incomplete filtrate.

Follow these application instructions are complementary: If an entry of acid leachates, is expected an entry by Lösevermittlern or a change of the redox potential in some cases of a harmful soil changes or legacy, more extraction procedure should be applied.
The estimation of the pollutant entry in the transition zone of the unsaturated to saturated zone, in particular the degradation and back retaining effect of unsaturated zone is taken into account. This, above all the following criteria are decisive: - groundwater floor distance, soil type, - content of organic matter (humus content), - pH, - groundwater recharge rates/seepage rate, mobility and biodegradability of the materials.
The influence of these factors on the fabric retention in the unsaturated zone is estimated on the basis of General existing scientific data and experience for each location. The use of fabric transport models may be appropriate.
Direct sampling and study of seepage when evaluating the measured concentrations of the substance, whose weather-related dynamics must be considered.

3.2. application of the test values of a) the test values apply to the transition area of the unsaturated water-saturated soil zone (location of the assessment). The place of Bodenprobennahme not necessarily corresponds with the location of the assessment of groundwater.
(b) for the assessment, whether it be expected that the test values for the leachate in the place of the evaluation are exceeded, are to take into account the changes in the concentrations of pollutants in the effluent when passing through the unsaturated soil zone and groundwater floor spacing, and their variations.
The assessment of pollutant concentrations in the leachate by material investigations on the basis of Inhomogeneities of the deposited waste is normally inappropriate waste deposits. The same applies to old sites with particularly uneven contaminant distribution. In these cases an estimation of pollutant concentrations in the leachate can be done by inference or accounting of the current measurements in groundwater, taking into account in particular the solids concentration in the on power.
(d) as far as the pollutant concentrations in the leachate can be measured directly, the sampling should be performed whenever possible in the place of the assessment of groundwater.
(e) as far as harmful soil changes and contamination in the water-saturated soil zone are located, they are evaluated as regards a threat to groundwater water regulations.
(f) waive related background situation of the groundwater region is taken into account in the application of the test values.
