Keeping trees and forests on the landscape is the easiest way to produce clean water—for drinking, recreation, and wildlife habitat. Studies show protecting watersheds upstream from a city is cheaper than building treatment plants to produce clean drinking water1. For example, a survey of 27 water suppliers in 2002 by the Trust for Public Land and the American Water Works Association found that for every 10 percent increase in forest cover in a source watershed, treatment and chemical costs decreased by about 20 percent.
