Water Quality

Air quality may be the most pressing issue, but scientists say that ultimately water — another human necessity — is in danger, too. Ash, burned soil and toxic residue from incinerated houses, businesses and machinery can make their way into lakes, rivers and reservoirs, said Carmen Burton, a hydrologist with the U.S. Geological Survey’s California Water Science Center in San Diego.

As students head back to class across California this month, many will sip water from school fountains or faucets that could contain high levels of lead. That’s because two-thirds of the state’s 1,026 school districts have not taken advantage of a free state testing program to determine whether the toxic metal is coming out of the taps and, if so, whether it exceeds federal standards.

Lauren Woeher wonders if her 16-month-old daughter has been harmed by tap water contaminated with toxic industrial compounds used in products like nonstick cookware, carpets and fast-food wrappers. … Tim Hagey, manager of a local water utility, recalls how he used to assure people that the local public water was safe. That was before testing showed it had some of the highest levels of the toxic compounds of any public water system in the U.S.

Scot Moody, general manager of the Stockton East Water District, said its water supply is experiencing a seasonal algae bloom. … Moody said despite the unpleasant smell emanating from the water, it meets all health standards and is safe for people and pets to drink.
