Rainwater harvest study finds roofing material affects water quality
Date:3/7/2011

U.S. Environmental Protection Agency doesn't regulate the quality of residential rainwater collected through harvesting, but some local agencies and states, like Texas and Hawaii which are among the most proactive offer voluntary water quality guidelines.

While some roofing materials performed better than others in the study, Kirisits said rainwater harvested from each of the roofs would still have to be treated if the consumer wanted to meet EPA's drinking water standards or reuse guidelines.
