Well testing water system Technology uses bacteria
Nikki Cobb San Bernardino County Sun (CA) October 15, 2005
Mention bacteria, and most people think of disease and decay. But the single-celled, microscopic "bugs" might be the key to providing affordable, safe water to thousands of Inland Empire residents.
Bioremediation using bacteria to clean groundwater has been used for years in Europe to treat nitrate-tainted water. But it's gaining ground in Southern California to remove perchlorate from water supplies.
"Perchlorate is showing up everywhere," said Peter Hall, a consultant to the Riverside-based Center for Environmental Microbiology. "The problem with perchlorate is pretty much universal, and we're in a hot spot."
Perchlorate, an ingredient in rocket fuel, fireworks and munitions, has been seeping toward area underground water supplies since World War II. It is thought to cause thyroid malfunction, particularly in infants.
The center is testing the technology at one of the West Valley Water District's Rialto wells. If it's successful and cost-effective, other water providers say they'll consider it, too.
