Only organic compounds reported above the detection limits are shown. 2. Bold indicates the analyte was detected at a concentration greater than the laboratory practical quantitation limit. A bolded value with a J qualifier represents exceedance of the laboratory method detection limit. Acronyms and Abbreviations: °C = degree Celsius < = the analyte was not detected at a concentration greater than laboratory practical quantitation limit -- = not applicable µg/L = microgram per liter µS/cm = microSiemen per centimeter CFC-11 = trichlorofluoromethane CFC-12 = dichlorodifluoromethane Dup = duplicate sample mg/L = milligram per liter NTU = nephelometric turbidity unit SRL = California Department of Public Health's Sanitation and Radiation Laboratories SU = standard pH unit Qualifier: J = Estimated concentration.
