- Regulatory standards obtained from United States Environmental Protection Agency, "2004 Edition of the

Drinking Water Standards and Health Advisories", Winter 2004, Document Number EPA 822-R-04-005.

- For purposes of calculating the average concentration, non-detect sample results were assigned a numerical

value of one-half of the detection limit.

- Regulatory standards in yellow are secondary drinking water regulations (SWDRs), which are

non-enforceable Federal guidelines regarding cosmetic effects (such as tooth or skin discoloration)

or aesthetic effects (such as taste, odor, or color) of drinking water.

- ND = Not Detected. Value in parentheses is the laboratory detection limit.

- The maximum detection limit for beryllium only exceeded the regulatory standard in two samples and in

subsequent samples at those locations the results were ND at 0.0005 ppm.
