Directly detecting harmful pathogens in water can be expensive, unreliable and incredibly complicated. Fortunately, certain organisms are known to consistently coexist with these harmful microbes which are substantially easier to detect and culture: coliform bacteria. These generally non-toxic organisms are frequently used as “indicator species,” or organisms whose presence demonstrates a particular feature of its surrounding environment.
Gordon Cologne served for 10 years in the California Legislature during the 1960s and early 1970s while the California State Water Project was being built.
His interest in water issues began from his early life in the Coachella Valley desert. An attorney, he worked in both the public sector in Washington, D.C, and then in private practice in California. He also served his local community as a member of the city of Indio City Council, including as mayor, before his decision to run for election to fill an open seat in the Assembly.
The turbulent Colorado River is one of the most heavily regulated rivers in the world.
Serving as the “lifeline of the Southwest,” the Colorado River provides water to 35 million people and more than 4 million acres of farmland in a region encompassing some 246,000 square miles.
The Colorado River Aqueduct, a 242-mile-long channel completed in 1941 by the Metropolitan Water District of Southern California, carries water from the Colorado River to to urban Southern California. The aqueduct is one of three conveyance systems of imported water to Southern California, the other two being the California Aqueduct and the Los Angeles Aqueduct.
In December 2007, the federal government and the seven states of the Colorado River Basin established guidelines for coordinated operation of Lakes Powell and Mead under low-reservoir conditions and for shortage allocations among the Lower Basin states. An ongoing severe drought and potential for a major shortfall in supplies led to the agreement.
California’s Colorado River Water Use Plan (known colloquially as the 4.4 Plan) intends to wean the state from its reliance on the surplus flows from the river and return California to its annual 4.4 million acre-feet basic apportionment of the river.
In the past, California has also used more than its basic apportionment. Consequently, the U.S. Department of Interior urged California to devise a plan to reduce its water consumption to its basic entitlement.
Contaminants exist in water supplies from both natural and manmade sources. Even those chemicals present without human intervention can be mobilized from introduction of certain pollutants from both point and nonpoint sources.
Construction began in 1937 to build the Contra Costa Canal, the first part of the federal Central Valley Project. The Contra Costa Canal runs from the Sacramento-San Joaquin Delta, where it draws its water near Knightsen, to the eastern and central parts of Contra Costa County. It is about 30 miles from San Francisco.
The C.W. Bill Jones Pumping Plant (formerly known as the Tracy Pumping Plant) sits at the head of the 117-mile long Delta-Mendota Canal.
Completed in 1951, the canal begins near Tracy, Calif. and follows the Coast Range south, providing irrigation water to the west side of the San Joaquin Valley along its route and terminating at Mendota Pool.
