Assistance Type: WATER QUALITY ALERT RESPONSE
Reasons: SOCs
 
Details: SOCs were sampled 11/5/18 and hexachlorocyclopentadiene was detected near the minimum detection limit and well below the MCL. As a result, monitoring for this contaminant is increased to quarterly beginning 1/1/19. If reliably and consistently below the MCL after four quarters, monitoring may be reduced to annual. If non-detect for three annual samples, system may apply for a waiver to return to every-3-year monitoring.
 
Associated Alerts: CHEM8197 - 01/07/2019 - HEXACHLOROCYCLOPENTADIENE
