Water quality


The Fresno Bee

The Fresno Bee (Fresno, Calif., Sept. 13) – The number of northeast Fresno homes in which tests reveal lead in the water coming from faucets has climbed to almost 300, including nearly 120 in which lead levels exceed the acceptable threshold set by the U.S. Environmental Protection Agency. Civil engineering professors Vernon Snoeyink of Illinois and Marc Edwards of Virginia Tech say the problems are related to the corrosion of galvanized pipes or lead-containing fixtures in homes in that part of the city, and what happens when a blend of water from the treatment plant and water pumped from wells flows through the galvanized household plumbing in affected homes.
