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, LCR = Lead and copper 90th percentile, LCRE = Lead and copper corrosion control

Response Time is the number of days from the alert date to the contact report date.
Results:  29 alerts found for this water system.Hide response time
