1 Toxics in Surface Water and Freshwater Fish of the Willamette River Basin, OR ( ) May, 2011 Oregon Water Conference Corvallis, OR Jim Coyle, Ben Johnson, Allen Hamel Oregon Department of Environmental Quality Laboratory and Environmental Assessment Division

2 Topics Oregons Toxics Monitoring Program Spatial / Temporal Scope Sampling Sites / Media / Timing Willamette River findings Senate Bill 737 and Pesticide Stewardship Partnership Overview/Summary Todays Presentation

3 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

4 Long-term –All major basins on a rotating schedule Initial / Long Term –Scope / develop Program –Willamette River Basin and associated tributaries –Water and freshwater fish Toxics Monitoring Program - Spatial Scope –Fish collections (Rogue & Umatilla – 2010 ) –Water collections (Rogue & Umatilla – 2011 )

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

6 Toxics Monitoring Program - Approach - Water PAHs PCBs PBDEs Metals Current-use & Legacy Pesticides Industrial Materials & Solvents Contaminants of Emerging Concern Targeted Organic Analytes (~ 270) (Continued) - pharmaceuticals, personal care products, plasticizers

7 Approach Organics in Water: Sampling Considerations Prior to seasonal reservoir releases Rising Limb of hydrograph (Continued) Spring transition

12 220 Detects 107 Detects 97 Detects Lower Middle Upper Summary Findings Waterborne Organics Fungicide/Herbicide Pharmaceutical Insecticide Organic (inc. DEET) Steroid

13 Number of Detects by Site and Analyte Group Summary Findings (Continued)

14 Number of Detects in Each Analyte Group in Tributaries vs. Main Stem Organics Insecticides Pharmaceuticals (inc. DEET) Steroids Fungicides/ Herbicides

15 Total PCBs (Continued) Summary Findings: Fish Tissue

16 Total DDT

17 2,3,7,8 Dioxin Equivalents (Continued) Summary Findings: Fish Tissue

18 Total PBDEs Total PBDE (Continued) Summary Findings: Fish Tissue

19 Total PBDEs Mercury (Continued) Summary Findings: Fish Tissue

20 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 Summary Findings: Waterborne Organics 2008 – 2009 Findings (5 collections)

21 Legacy pesticides generally below screening level criteria for the protection of human health Halogenated industrial chemicals (PCBs & dioxins/furans) remain a concern Mercury levels remain elevated Elevated PCB concentrations in Eugene area fish fillets re-assessed in 2009 Summary Findings: Fish Tissue 2008 Findings

22 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 states largest municipal wastewater treatment plants

23 SB 737 Background (Continued) Treated effluent from 52 facilities sampled/analyzed twice for P3 and other (incidental) pollutants in 2010 (Jul/Aug & Nov/Dec)

24 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)

25 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 Background (Continued)

26 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) Cholesterol Coprostanol Beta-sitosterol Pyrene Arsenic SB 737 Findings

27 Facilities with measurable pharmaceuticals/personal care products SB 737 Findings (Continued)

28 Commonly Detected Pesticides –Herbicides Diuron detected in 70% of facilities (summer) Imazapyr detected at 10% of facilities (summer) Also….2,4-D, Triclopyr, Dicamba, 2,4-DB, Pentachlorophenol, Prometon –Insecticides Imidacloprid detected at 12% of facilities SB 737 Findings (Continued)

29 SB 737 What Next ? Effluent data publically available in May Presentation to EQC in mid-June Reduction Plans due July 1, 2011
