J: Estimated value

ND: Not detected

RMEG: Reference dose media evaluation guide

CREG: Cancer risk evaluation guide for 10-6 excess cancer risk

MCL: Maximum contaminant level

#: Risk-based level developed by USEPA Region III

No contaminants were detected in residential wells designated #I, #2, #4, #6 and #9. Results from residential well #3 taken in 1986 are not reported in this table because one of two duplicate samples contained numerous contaminants at high levels, but none were found in the other duplicate or in a re-sample taken on 1987. No contaminants were reported in samples taken in community supply wells #20, #22 and #24.

Note: Results for acetone and methylene chloride are not reported in this table because analyses did not pass quality assurance/quality control requirements.
