HERBICIDES Why monitored? • Potentially harmful to aquatic life and humans through drinking water Where are they coming from? • Runoff from agricultural and residential application How can we minimize their presence in our waterways? • Apply only as absolutely necessary, follow application instructions. • Maintain vegetation around and along waterbodies. • Use recommended agricultural erosion control practices. • Properly dispose of herbicide containers (collection programs) • Do not dump leftover herbicide on ground, down sink, or down stormwater drains.
2006 Herbicide Parameters • Sampled for 2 herbicides in Spring 2006 • most likely time of year for herbicide application • Triazines • highly persistent in soil • EPA standard of 3.0 micrograms /L for drinking water • 350 micrograms/L for acute aquatic life criteria • 12 micrograms/L for chronic aquatic life criteria • Metolachlor • highly persistent in water • unregulated by EPA
Herbicide Results Triazines ONLY detected at: • K501 (Eagle Creek) – 8.6 micrograms/liter • Greater than drinking water supply standard of 3 ug/L • Less than chronic aquatic life criteria of 12 ug/L Metolachlor found at 4 sites, the greatest being: • K501 (Eagle Creek) – 3.38 micrograms/liter

Where are they coming from? • Failing septic systems, straightpipes, leaking sewage lines • Inadequately treated discharge from municipal sewage plants • Livestock (runoff from pasture or direct access to waterbody) How can we minimize their presence in our waterways? • Properly maintain septic systems • Increase access to sewer systems • Install fencing to keep livestock out of waterways • Maintain vegetated buffers around waterbodies
