Alerts indicate water quality tests with analytical results greater than the detection limit or one-half of the maximum allowable contaminant level which may require some follow-up actions by Drinking Water Services. See the Contacts link for reports on follow-up actions. Alerts are not water quality violations. Violations for this water system can be found here.

Alert Type Abbreviations:  CHEM = Chemical, COLI = Coliform, SOURCE = Coliform source sample*, LCR = Lead and copper 90th percentile

*Non-alert (water quality notice)
