Untreated sewage at all eight treatment plants tested in Los Angeles County contained cocaine metabolite, according to data obtained from the Los Angeles County Sanitation Districts. Palmdale and Lancaster had the highest concentrations, averaging 3.5 parts per billion. The lowest, averaging 1.4 ppb, were from Long Beach and Valencia.
In all the Los Angeles County locations, the cocaine metabolite was more concentrated than in Omaha and in Italian, Swiss and British cities, which all had less than 1 ppb, according to a comparison of several studies.
