RBSP (River Basin Specific Pollutant)
A pollutant identified at national or river basin level as a significant local risk — not covered by the EU-wide priority substances list.
River Basin Specific Pollutant. Substances causing significant risk to or via the aquatic environment in a specific river basin or Member State, but not included in the EU priority substances list. Under Directive (EU) 2026/805, RBSP monitoring now contributes to 'good chemical status' rather than just ecological status. Member States must set national EQS for RBSP by 22 December 2027. Annex VII Part C contains 6 formerly-priority substances demoted to RBSP with EU-harmonised EQS.
