Travel blank sample from May 24, 2024 contained detection of toluene at 0.17 µg/L.2. Bold font indicates a detection above the method detection limit. 3. Shaded cell indicates an exceedance of the California MCL. 4. Baseline samples were not collected at CDCR-EW-2. CRT samples collected 2 days after well development represent the baseline samples.Acronyms and Abbreviations:-- = not applicable<0.5 = not detected greater than the laboratory reporting limit (practical quantitation limit)µg/L = microgram per literCDCR = California Department of Corrections and Rehabilitation CRT = constant rate testCFC-11 = trichlorofluoromethaneCFC-12 = dichlorodifluoromethaneID = identificationMCL = maximum contaminant levelPCE = tetrachloroetheneTCE = trichloroetheneTVOC = total volatile organic compoundQualifier:J = Estimated concentration.Page 1 of 1
