Overview Status Future Direction

Pharmaceuticals & Personal Care Products (PPCPs) Hormones and Sterols Perfluorinated Compounds
4
ECs identified as a top research priority ◦ Eventually, the Commission will have to make regulatory decisions regarding ECs ◦ Don’t want to be in the position of being asked what we are doing……and say “nothing”. Be proactive
5
Data = Informed Decisions Conducting this research ourselves allows us to: ◦ Control the data ◦ Report the results ◦ Control what is said about the results by publishing, informing the press and interacting with the public.
6
To date, no evidence has been found of human health effects. ◦ EPA – Global Water Research Coalition – Water Research Foundation However, scientists are concerned over the lack of fetal exposure studies and studies involving possible effects of complex mixtures and long- term exposure.
7
7 Effects on aquatic life are a major concern ◦ Risks for aquatic organisms much greater than humans Continuous exposure Exposure to higher concentration in waste streams from many different sources Possible low dose effects Intersex – classic example Other reproductive effects and anomalies Neurobehavioral Nest guarding Homing during migration (salmon) Fish replace the canary
8
Do we find ECs in the Ohio River? Are fish and other aquatic organisms showing effects possibly caused by exposure to ECs? If YES… ◦ Develop a strategy for testing fish health indicators and develop a routine monitoring strategy.
9
2005 ◦ Document presence of ECs ◦ Look for possible fish health effects *REVIEW*
10
POCIS and SPMD sampling units ◦ Presence/absence only Fish Health ◦ 200 fish sampled *REVIEW* Polar Organic Chemical Integrative Sampler - Hydrophilic Contaminants Semi-Permeable Membrane Device - Lipophilic Contaminants
11
Hormones found ◦ In effluent mixing zones ◦ At upstream reference locations Fish showed possible signs of health effects ◦ No Intersex found!! *REVIEW*
12
A more comprehensive look at the occurrence of Emerging Contaminants within the mainstem Ohio River ◦ 24 Locations Longitudinal spread Range of potential for occurrence POTW mixing zones Tributaries ‘Background’ areas ◦ 121 Pharmaceutical and Personal Care Compounds ◦ Hormones & Sterols ◦ Nonylphenol (+) ◦ Perfluorinated Compounds (PFCs) ◦ Optical Brighteners
14
Document occurrence of ECs within the mainstem Ohio River Identify areas of the river with a greater risk potential (to aquatic organisms) ◦ Number of contaminants present ◦ Levels observed ◦ Single chemical ‘WERF ranking’ (ongoing project) Prioritizing Trace Organic Compounds
15
USEPA NERL – Cincinnati ◦ APEOs – NPEOs - Optical Brighteners – PFCs ◦ Researchers are national/international experts in the EC field AXYS Analytical ◦ Developed PPCP methods for EPA (1694; 1698) Waters ◦ Demonstrating new analytical capabilities
16
$84,000 Project Cost $50,000 – River Users Program ◦ Held in ‘reserve’ $73,000 (+) available from EPA/NRSA Sampling ◦ $6K per site x 25 sites = $150,000
17
Sampling ◦ September - October 2009 Results Available ◦ Oct. – Nov. 2009 Data assessment ◦ Dec. 2009 – Jan. 2010 Findings reported to Technical Committee ◦ Feb. 2010 Draft report/pub out for review ◦ March - April 2010
20
Phase 3
21
Research Committee – June 2009 ◦ Priority: The development of fish health indicators for detecting the presence of and effects from exposure to emerging contaminants.
22
Use Phase 2 results to identify a ‘gradient of (EC) condition’ ◦ Areas with differing potential for showing biological response Occurrence of ECs Type Concentration Risk Potential – ongoing WERF Research Project Test various candidate measures of Fish Health along the gradient identified
23
$315,000 proposal submitted to USEPA through the Regional Methods development program. ◦ Peer review prior to submittal Very good reviews ◦ Pulled in many different partners USEPA USGS WVU St. Cloud State Proposal rejected on a submission technicality! Currently searching for funding support.
