Challenge # 11 Toxic Compounds Sources of toxic compounds include pesticides, motor vehicles, industrial activities, atmospheric deposition, spills, and illicit dumping. Toxic substances lower dissolved oxygen, stress sensitive flora and fauna, enter the aquatic food chain, and may degrade the appearance of water surfaces. Periodically elevated concentrations of toxic compounds may be responsible for the paucity of aquatic species diversity found in the Huron River’s urban tributaries and slightly impaired populations of the Huron main stem. What protection activities address the challenge of toxic compounds? Home Toxics Program Pollution Prevention Community Partners for Clean Streams Hazardous Waste Regulations Metals found in surface waters and bottom sediments in the project area include lead, arsenic, zinc, cadmium, manganese and barium. Some sediment samples from Geddes Pond, for example, were found to be "heavily polluted" with arsenic and lead, according to U.S. EPA standards. Toxic Compounds Response Objective: Maintain or attain water quality standards and minimize the exposure to and consumption of water with elevated levels of toxic compounds in Washtenaw County. Toxic Compounds Response Assessment: There are no TMDL plans under implementation that involve toxics; however, lack of water quality monitoring data makes quantitative assessment for toxic compounds impossible. 50 Washtenaw County manages a Home Toxics Reduction Program designed to assist residents in the proper disposal of toxic materials commonly used in homes. The Home Toxics Reduction Program collected over 729 thousand pounds of toxic materials between 1994 and 2004. Substances included flammables, oil-based paints, pesticides, batteries, mercury, and more. Figure 12: Home Toxics Drop-off Station Source http://www.ewashtenaw.org/government/departments/planning_environment/dpw/ hhw_location_html, May 2006 The County’s Pollution Prevention Program ensures that chemicals are properly handled and stored. It also provides for source control by reducing the amount of toxic substances used. In addition, the County has a “Polluter Pay” regulation in place to respond to instances of toxic dumping.
The Community Partners for Clean Streams program produces educational materials that provide guidance on toxic compounds. The program emphasizes utilizing the “least toxic option” when purchasing products like cleaners and paints. The program also provides tips for reduction of use, and for proper storage and disposal of these items. Hazardous waste regulations enable the County’s Emergency Management department to have a hazardous material response team (HAZMAT). The County also has 24-hour response to spills and releases coordinated with the MDEQ. Next Steps: There is an opportunity to prevent toxics from becoming a widespread water quality issue in the County. This will require continued and expanded support for successful activities like the Home Toxics Reduction Program. Water quality monitoring is needed to determine and catalog the extent to which toxics maybe a problem in the water system. 51
