Acute toxicity range
Chronic toxicity range
Conclusions
• Appears to be no risk of acute toxicity to target PPCPs in sampled lakes and rivers
• Chronic toxicity cannot be ruled out
• Other PPCPs or their metabolites may be present
Limiting The Impact
Things You Can Do
• Don’t Rush to Flush!
• Fill prescriptions as needed
• Drug Take‐Back Programs
• Educate
Things We Can Do
• Optimize the effectiveness of prescriptions
• Sustainable farming/cattle practices
• Improve WTP technology
