Text Box: Notes:  - ug/L = micrograms per liter  - * Chlorination byproducts in water supply well (referenced in SWDA drinking water regulations as THMs, or trihalomethanes).  MCL for total concentration of THMs is 100 ug/L. - F = The analyte was positively identified but the associated numerical value is below the RL. - J = The analyte was positively identified, the quantitation is an estimate. - R = The data are unusable due to deficiencies in the ability to analyze the sample and meet QC criteria. - U = The analyte was analyzed for, but not detected. The associated numerical value is at or below the MDL. - NA = Not sampled for this parameter * Values represent MDLs for the analytical procedure used

1 = Indicates data is screening analytical data only.

2 = Chemron quantitation limits varied over the years that samples were analyzed by the lab.� Values listed are for June 1995 through February 1996.

Detected concentrations are in bold type.

Concentrations above the MCL are shaded and have a box around them.

Shaded areas indicate analytical data analyzed by ITS Laboratories.

Text Box: Notes:  - ug/L = micrograms per liter - * Chlorination byproducts in water supply well (referenced in SWDA drinking water regulations as THMs, or trihalomethanes).  MCL for total concentration of THMs is 100 ug/L. - F = The analyte was positively identified but the associated numerical value is below the RL. - J = The analyte was positively identified, the quantitation is an estimate. - R = The data are unusable due to deficiencies in the ability to analyze the sample and meet QC criteria. - U = The analyte was analyzed for, but not detected. The associated numerical value is at or below the MDL. - NA = Not sampled for this parameter. * Values represent MDLs for the analytical procedure used.

     

1 = Indicates data is screening analytical data only

2 = Chemron quantitation limits varied over the years that samples were analyzed by the lab.� Values listed are for June 1995 through February 1996.

Detected concentrations are in bold type.

Concentrations above the MCL are shaded and have a box around them.

Shaded areas indicate analytical data analyzed by ITS Laboratories.
