Farming and tap water

For millions of Americans, tap water comes with an unwanted dose of toxic contaminants that come from the use of pesticides, fertilizers, animal wastes and other substances in farming. These contaminants are associated with short-term health hazards like acute gastro-intestinal illnesses and long-term health threats like different types of cancer, thyroid disease, endocrine disruption and birth defects. Farm pollution does not just contaminate drinking water for people living in farm country – people in downstream cities also have these dangerous substances in their water.
