  "heading": "BAT is to monitor pollutants in groundwater with a frequency of at least once every 6 months and in accordance with EN standards. If EN standards are not available, BAT is to use ISO, national or other international standards that ensure the provision of data of an equivalent scientific quality.",
  "text": "The monitoring frequency may be reduced to once every 2 years based on a risk assessment or if pollutant levels are proven to be sufficiently stable (e.g. after a period of 4 years).\nThe monitoring may not apply if the substance concerned is not used in the process and if the groundwater is proven not to be contaminated with this substance.\nSpecific substances are monitored, depending on the composition of biocidal products which are used or were previously used in the process.\nThe monitoring only applies to plants using solvent-based treatment chemicals. Specific substances are monitored, depending on the solvents in use in the process.\nSubstance/Parameter\nStandard(s)\nBiocides\nEN standards might be available depending on the composition of the biocidal products\nAs\nVarious EN standards available\n(e.g. EN ISO 11885, EN ISO 17294-2, EN ISO 15586)\nCu\nCr\nSolvents\nEN standards available for some solvents\n(e.g. EN ISO 15680)\nPAHs\nEN ISO 17993\nBenzo[a]pyrene\nEN ISO 17993\nHOI\nEN ISO 9377-2",
