Page 1, ABSTRACT section: AHTN should be replaced with HHCB. Page 17, table 7: AHTN and HHCB should be switched. Page 21, SURFACE WATER section, AHTN should be replaced with HHCB. Page 25, SURFACE WATER section: Text should be revised to state that six EDCs were detected rather than seven EDCs. Also, AHTN should be deleted from the list. Page 26, table 9: AHTN should be replaced with HHCB in all instances. Page 26, GROUND WATER section: Text should be revised to state that three EDCs were detected in groundwater samples as AHTN was not detected at site 43. Page 27, DRINKING WATER section: Text should be revised to state that six EDCs were detected rather than seven. Also, AHTN should be deleted from the list. Page 30, table 13: AHTN should be replaced with HHCB. Page 33, SUMMARY AND CONCLUSIONS section, AHTN should be replaced with HHCB. Page 39, appendix 1: AHTN and HHCB should be switched. Page 43, appendix 2: AHTN and HHCB should be switched. Page 46, appendix 4: AHTN and HHCB should be switched.
