##  [EU Strengthens Water Protection Rules with New PFAS, Pharmaceutical and Bisphenol Limits under Revised Directive](/index%2ephp/consumer-industry-news/eu-strengthens-water-protection-rules-with-new-pfas-pharmaceutical-and-bisphenol-limits-under-revised-directive) 

March 25, 2026

The European Parliament and the Council of the European Union have adopted a draft directive revising key EU water legislation, including the Water Framework Directive (2000/60/EC), Groundwater Protection Directive (2006/118/EC), and Environmental Quality Standards Directive (2008/105/EC). The update introduces new pollutant limits, expands monitoring requirements, and modernizes the EUs water quality framework to address emerging contaminants.

Key Amendments and Proposed Limits  
1\. PFAS (Per- and Polyfluoroalkyl Substances)  
The directive introduces group-based regulation of PFAS, a major shift from substance-by-substance control.  
Surface Waters (EQS): Limit set for the sum of 25 PFAS (exact numeric EQS values are specified in annexes of the draft and may differ by water body type; commonly proposed values in legislative drafts are in the low ng/L range, e.g., single- to double-digit ng/L levels for annual average concentrations).

1.Groundwater  
Limit for the sum of 20 PFAS aligned with drinking water standards.  
Indicative benchmark (aligned with Drinking Water Directive (EU) 2020/2184):0.10 g/L (100 ng/L) for sum of 20 PFAS and 0.50 g/L for total PFAS (broad parameter)  
Specific Hazardous PFAS Subset: Additional stricter limits apply to a subgroup of the 4 most hazardous PFAS (values set significantly lower than group limits; typically sub-ng/L to low ng/L range depending on compound).  
Notable Substances: Perfluoro octane sulfonic acid (PFOS): already regulated; EQS further tightened (historically ~0.65 ng/L AA-EQS in EU standards).  
Trifluoroacetic acid (TFA): included in group limit; no standalone EQS yet but flagged for future restriction.

2\. Pharmaceutical Residues (Medicinal Products)  
Surface Waters:Newly listed priority substances with very stringent EQS due to endocrine effects:  
Ethinylestradiol:Proposed EQS: ~0.035 ng/L (annual average)  
Estradiol:Proposed EQS: ~0.4 ng/L  
Estriol:Indicative EQS under evaluation (typically higher than estradiol; exact binding value subject to final annex)  
Groundwater:Selected pharmaceuticals added with Member Statedefined threshold values based on risk assessment.  
Monitoring Approach: Introduction of effect-based trigger values (EBTs) to assess cumulative estrogenic activity rather than relying solely on individual concentration limits.

3\. Bisphenol Substances  
Immediate Regulation: Bisphenol A designated as a priority hazardous substance:  
Proposed EQS: ~0.2 ng/L (annual average) for surface water (extremely low due to endocrine disruption risk)  
Watch List / Group Control: Sum of bisphenols introduced for monitoring purposes (no fixed EU-wide numeric limit yet; data collection phase).  
Mandatory identification and monitoring of:Bisphenol B, Bisphenol S  
National limits may be set at river basin level.

4\. Other Emerging Pollutants (Watch List)  
Currently monitoring-focused (no binding EU-wide limits yet):  
Microplastics harmonized methodologies under development  
Antimicrobial Resistance (AMR) indicators surveillance-based thresholds expected in future revisions  
System-Level Regulatory Changes

Expanded Chemical Status Definition:  
Now includes both EU priority substances and river basin-specific pollutants under a unified framework.  
Retention List:Introduced for substances with declining risk but still requiring surveillance.  
Standards Alignment:Groundwater PFAS thresholds directly linked to drinking water parametric values.  
20-Year Phase-Out Rule:Discharges of priority hazardous substances must be eliminated within 20 years of listing.
