Toxics Monitoring Program
- Objectives -
• State-wide, watershed-based toxic pollutant monitoring and evaluation program
• Document concentrations of toxic pollutants in Oregon waters and biota, interpret findings relevant to established criteria
• Support pollutant reduction strategies and assess progress towards meeting established criteria
Long Term
![Page 4: Toxics in Surface Water and Freshwater Fish of the Willamette River Basin, OR (2008-2009) May, 2011 Oregon Water Conference Corvallis, OR Jim Coyle, Ben](https://reader033.vdocuments.us/reader033/viewer/2022060106/5516521b550346b2068b5956/html5/thumbnails/4.jpg)
• Long-term
– All major basins on a rotating schedule
Initial / Long Term• 2008 -2010
– Scope / develop Program– Willamette River Basin and associated
tributaries – Water and freshwater fish
Toxics Monitoring Program
- Spatial Scope -
• 2010 - 2011– Fish collections (Rogue & Umatilla –
2010)
– Water collections (Rogue & Umatilla – 2011)

Toxics Monitoring Program
- Approach -
Toxic pollutants suspected to: - be present in Oregon’s surface waters - pose threats to human health and the
environment
Environmental media of interest
- Water column (2008 - 2010)
- Fish tissue (2008 – 2010)
- Sediment / artificial samplers (Future)
Toxic pollutants and media of interest

• Surface water sampled five times at 20 sites• No water quality criteria exceedances
documented
• Herbicides were most frequently detected pollutant class; insecticides rarely detected
• Coprostanol (fecal contamination indicator) was found at nearly every site
• Multiple, low-level detects for “emerging contaminants”

Senate Bill (SB) 737
Background
• Oregon Legislature directed ODEQ to develop list of 118 Priority Persistent and bioaccumulative Pollutants ( “P3” list)
• P3 chemicals known/suspected to pose risks to human and environmental health, selected through deliberative process with public/stakeholder input
• Concentrations of P3 chemicals measured in final, treated effluent discharged by state’s largest municipal wastewater treatment plants
![Page 23: Toxics in Surface Water and Freshwater Fish of the Willamette River Basin, OR (2008-2009) May, 2011 Oregon Water Conference Corvallis, OR Jim Coyle, Ben](https://reader033.vdocuments.us/reader033/viewer/2022060106/5516521b550346b2068b5956/html5/thumbnails/23.jpg)
SB 737
Background (Continued)
• Treated effluent from 52 facilities sampled/analyzed twice for P3 and other (incidental) pollutants in 2010 (Jul/Aug & Nov/Dec)
![Page 24: Toxics in Surface Water and Freshwater Fish of the Willamette River Basin, OR (2008-2009) May, 2011 Oregon Water Conference Corvallis, OR Jim Coyle, Ben](https://reader033.vdocuments.us/reader033/viewer/2022060106/5516521b550346b2068b5956/html5/thumbnails/24.jpg)
• When possible, measured pollutants were compared to maximum contaminant level (MCL) established by the National Primary Drinking Water Regulations (33 pollutants)
• Pollutants lacking established MCLs compared to “Plan Initiation Levels” established by the Environmental Quality Commission (EQC).
• Facilities required to develop Reduction Plans when measured concentrations exceed targets
SB 737
Background (Continued)
![Page 25: Toxics in Surface Water and Freshwater Fish of the Willamette River Basin, OR (2008-2009) May, 2011 Oregon Water Conference Corvallis, OR Jim Coyle, Ben](https://reader033.vdocuments.us/reader033/viewer/2022060106/5516521b550346b2068b5956/html5/thumbnails/25.jpg)
• Effluent analyzed for > 400 chemicals using 15 methods
• 116 “P3” compounds measured in effluent included:• Pharmaceuticals & personal care products• Current use pesticides• Legacy compounds • PCBs, dioxins, furans• Flame retardants • Musks /fragrances
SB 737

• Of 116 “P3” compounds measured in the effluent:
• 33 detected, 5 exceeded Plan Initiation Levels
• Cholesterol/coprostanol -byproducts of human digestion• Temporary rulemaking eliminated need to develop
reduction plans for cholesterol/coprostanol
• 5 facilities completing reduction plans for 3 chemicals • Beta-sitosterol (2), Pyrene (1), & Arsenic (2)

Pesticide Stewardship Partnerships (PSPs):Overview
Monitor for current use pesticides in surface waters
from drift & runoff
Identify streams with elevated pesticide concentrations
Collaborate to implement voluntary
best management practices
Follow-up monitoring to determine improvements
over time
