Division BAT 44 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.
United Kingdom
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).
| The 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. | |
| Specific substances are monitored, depending on the composition of biocidal products which are used or were previously used in the process. | |
| The monitoring only applies to plants using solvent-based treatment chemicals. Specific substances are monitored, depending on the solvents in use in the process. | |
