Long ago in lands far away Enter the US Geological Survey

 First reported in Florida in 1970’s  Male Goby fish showed female characteristics  Downstream from pulp mill effluent  Sitosterol was active chemical from trees  Reported in other rivers with pulp effluent  Resurfaced in England in

USGS investigation - Kolpin et al. 2002

  139 rivers  One time water samples  Measured hundreds of pharmaceuticals, industrials, pesticides, hormones

 17 antibiotics  15 prescription drugs  7 non-prescription drugs  39 other chemicals  18 hormones, including several different steroids  What’s the harm?

Reproduction IQ Behavior

 Congress weighs in- hearings Sept 18, 2009  USGS to continue  Agricultural run-off  Drinking water and groundwater

 Columbia River  Ohio River  California  Minnesota  Potomac River  US Geological Survey  Individual scientific research

 Many chemicals into the water  Effects on fish downstream from WWTP  Effects from animal feedlots  Sediment as sinks
