When I fill my bathtub with water, the water has a greenish tint. What causes this coloration in my water?

A green or greenish blue tint to the water is usually associated with copper contamination in the water. Copper most commonly contaminates the water from household plumbing. In order to determine whether copper contamination is causing the coloration in your water, you may want to have your water analyzed for copper. To have your water tested you may call your state certification officer to get a list of certified laboratories in your state. A list of state certification officers is available at http://water.epa.gov/scitech/drinkingwater/labcert/statecertification.cfm.
