Mandate (CMEP)  Report on the use of alternative effect-based monitoring methods (e.g. biomarker, bioassays, TIE) needed for investigative monitoring and to better evaluate the link between chemical and ecological status and the effects of mixture of pollutants and emerging pollutants.

Complementary methods can be used in the design of WFD monitoring programmes for: Identification of problem, e.g., by using screening methods (test kits) or passive sampling devices. Selection of monitoring points, (e.g., in the grouping of water bodies for operational Monitoring): complementary methods may be used to demonstrate the representativeness of sampling points. Selection of quality elements, e.g., the selection of other pollutants that are part of the ecological status. Information derived from bioassays and toxic identification and evaluation (TIE) may be used to select compounds based on ecological relevance.. 7

Complementary methods in investigative monitoring Use for investigative monitoring to identify the reason for any failure to achieve environmental objectives, in circumstances where the reason is unknown and to ascertain the magnitude and impact of accidental pollution. Test kits including, e.g., immunoassays specific to certain priority substances or other pollutants allow fast screening of large number of samples and can be cost-effective tools to identify pollution sources as well as to characterise the extent of accidental pollution. In case of MAC-EQS exceedance, investigative monitoring should be used to ascertain this non-compliance in more detail. Both, spot sampling and time-integrated measurements may not detect acutely toxic spikes of seasonally-variable compounds like pesticides; the use of bioassays may be beneficial. 8
