Los Angeles city officials Monday reported that they have found "relatively high levels of contaminants" in a Glendale water well field near Griffith Park where six out of nine wells have been shut down.
Mike Hopkins, Glendale water services administrator, said results of tests conducted by the Los Angeles Department of Water and Power "confirmed what we already knew or suspected."
The exact levels of contaminants are not expected to be released until early December after DWP findings are confirmed by results from an independent laboratory, Hopkins said.
The Glendale water wells are among dozens in the San Fernando Valley basin that have been shut down after traces of solvents--principally trichloroethylene (TCE) and perchloroethylene (PCE)--were discovered in 1979. The contaminants are suspected to cause cancer after long-term, regular exposure.
