Dangerous Substances Directive (fresh water)
http://www.environment-agency.tv/ye/qa-ea-doc/s-enviro/viewpoints/3compliance/2fwater-qual/3-2-4.html

1. Many human activities, and some natural processes, release chemicals into watercourses. Some of these substances require strict control if harm to the environment is to be minimised. The most harmful, or dangerous, substances are controlled by the EC Dangerous Substances Directive (76/464/EEC) and the associated set of Daughter Directives.

2. Substances that have the potential to cause the most harm to aquatic life due to their persistence, toxicity or bio-accumulation are known as List 1 Dangerous Substances. The Directive requires that pollution by these substances is reduced by eliminating their discharge. Substances which are thought to be harmful, but not to the same degree as List 1 substances are known as List 2 Dangerous Substances (above), and discharges of these substances are to be reduced.

3. Every listed dangerous substance has a concentration limit known as an Environmental Quality Standard (EQS). The EQS is usually an upper concentration (the exception being pH which has both upper and lower limits) and is set for the receiving watercourse and not the discharge itself. The dangerous substance is not believed to be detrimental to aquatic life at any concentration below its EQS limit. EQSs vary for each substance and can be different for fresh, estuarine or coastal waters (Table 3). It can be an annual average concentration, a maximum allowable concentration or a percentile concentration. If the EQS is exceeded at a site then it will not be compliant with the Dangerous Substances Directive (it will have failed). The cause of every non-compliance must be fully investigated and action plans to remedy the situation must be put in place where necessary.

4. EQSs must not be exceeded in any controlled watercourse in England and Wales. Human activities produce the greatest levels of List 1 and List 2 substances, with industrial plants or sewage treatment works being the major sources. Agency monitoring for EQS compliance, therefore, is largely carried out downstream of this type of discharge if there is the possibility that the effluent will contain dangerous substances. Monitoring at these sites is likely to represent the 'worst case' for EQS compliance. The Agency carries out additional background monitoring at the bottom of major river catchments (known as 'National Network' monitoring). The downstream monitoring is carried out monthly, while background monitoring is carried out quarterly. The results are gathered and reported annually
