PALMDALE WATER DISTRICT EXPECTED TO OK ADDITIONAL FILTRATION.Byline: CHARLES F. BOSTWICK Staff Writer PALMDALE -- Palmdale Water District officials are expected tonight to approve spending $34.3 million to modify the Palmdale water treatment plant to reduce a treatment byproduct by·prod·uct or by-prod·uct n. 1. Something produced in the making of something else. 2. A secondary result; a side effect. Noun 1. linked to cancer and miscarriages. The contract going before the water board tonight is for Santa Barbara Santa Barbara (săn'tə bär`brə, –bərə), city (1990 pop. 85,571), seat of Santa Barbara co., S Calif., on the Pacific Ocean; inc. 1850. County-based Cushman Contracting Corp. to install a filtration system that will remove organic material and trihalomethanes, or THMs, formed through the reaction of chlorine used as a disinfectant with organic material in the water from the California Aqueduct The California Aqueduct is a 444 mile (715 km)-long[1] aqueduct in the United States that carries water from Northern California to Southern California. . ``That will make a substantial decrease in THMs in the system,'' water district General Manager Dennis LaMoreaux said. The modifications will allow the water district to use more California Aqueduct water to supply homes and businesses without having to blend it with well water to keep the THM level of water coming out of faucets below the federal standard of 80 parts per billon bil·lon n. 1. An alloy of gold or silver with a greater proportion of another metal, such as copper, used in making coins. 2. An alloy of silver with a high percentage of copper, used in making medals and tokens. . A 1998 California Department of Health Services Department of Health Services may refer to:
Other studies have linked THM to bladder or colonorectal cancer, and to a birth defect birth defect Genetic or trauma-induced abnormality present at birth. A more restrictive term than congenital disorder, it covers abnormalities that arise during the formation of an embryo's organs and tissues and does not include those caused by diseases (e.g. called spina bifida, in which the spinal cord spinal cord, the part of the nervous system occupying the hollow interior (vertebral canal) of the series of vertebrae that form the spinal column, technically known as the vertebral column. is not properly enclosed by bone. The work is expected to take about two years, LaMoreaux said. The filtration system will use granular activated carbon, used in many home water purifiers that attach to kitchen faucets. Work is already under way on the $13 million first phase of changes to the treatment plant, including changes to the settling basins where organic material and other sediments are removed from the water. Workmen right now are erecting a cover over the settling basins, which by keeping the sunlight off the water will inhibit the growth of algae algae (ăl`jē) [plural of Lat. alga=seaweed], a large and diverse group of primarily aquatic plantlike organisms. These organisms were previously classified as a primitive subkingdom of the plant kingdom, the thallophytes (plants that , LaMoreaux said. That will reduce the need for chlorine that contributes to the formation of THMs. ``This makes a better environment for treating the water,'' LaMoreaux said. The cover is built to accommodate electricity-generating solar panels if water officials decide to add them in the future, LaMoreaux said.
