RESULTS ARE PRESENTED IN UG/L.
Effective with the August 2014 sample, analytical method was changed to SW846-8260.
J: Detected but below the Reporting Limit; therefore, the result is an estimated concentration (CLP J-Flag)
B: Analyte was found in the associated blank at a concentration >1/2 RL.
BH: MB greater than one half of the RL, but the sample concentrations are greater than 10x the MB.
