3.1.1.2. Target setting
Target setting for substances was identified by comparing their occurrence with environmental quality standards, groundwater quality standards and detection limits. The used targets of the pesticides are listed in Annex 6. For this, the following sources were considered:
Surface waters
- Environmental Quality Standards (EQS) of the pesticides listed under the priority substances of the WFD; AA-EQS (annual average EQS) which are protective against chronic toxicity and MAC EQS (maximum acceptable concentration EQS) which should protect against acute toxicity.
- The maximum acceptable detection limit, according to the Watch List under Commission Implementing Decision (EU) 2015/495 and Commission Implementing Decision (EU) 2018/840.
- Environmental Quality Standards (EQS) of the pesticides listed under the River Basin Specific Pollutants (RBSP); if available: AA-EQS and MAC EQS. The EQS value for RBSPs can vary between Member States (MS). For the assessments based on Waterbase – Water Quality data (see section 1.1.1), the lowest reported EQS for a substance was used. When three or more countries regulated a substance, it was handled as relevant and included into the surface water assessment.

What about including RACs (acute and chronic Regulatory Acceptable Concentrations) so that more or less all pesticides could have an effect-related threshold, not only those listed under some priority list?
3rd bullet, 2nd sentence: This does not make sense, as some member states (e.g. Italy) used for most substance the drinking water guidance value of 0.1 µg/L as EQS for surface water, without any justification. Therefore, only ecotox-based EQSs should be included in this process.
3rd bullet, last sentence: what is the justification to consider them relevant?
