Assistance Type: WATER QUALITY ALERT RESPONSE
Reasons: Disinfection Byproducts
 
Details: I received an alert for a single TTHM result sampled at the Cape Meares Community Center (site ID 2DBP-02) on 8-16-22 which was measured to be 0.0866 mg/l. I e-mailed both David Nordman and Christian Anderson (osidewaterchristian@gmail.com) on 8-22-22 letting them know (see contact report for Cape Meares from 8-22-22) and sent a link to the OEL report template and information on our website at:https://www.oregon.gov/oha/ph/healthyenvironments/drinkingwater/rules/stage2/pages/opeval.aspx. Although results for the Oceanside system (PWS ID 00585) were not yet visible on data-online, I also mentioned the possibility of an OEL exceedance for Oceanside, which would require a separate OEL report.

8/24/22 Update - I e-mailed David Nordman and Christian Anderson that the TTHM OEL was also exceeded for Oceanside (00585) with the TTHM OEL calculated to be 0.082 mg/l. No alert was generated for Oceanside because the latest individual results were below 0.080 mg/l, however, when factored into the previous quarterly results, the most recent sampling did result in a TTHM OEL exceedance for 3rd quarter 2022. I requested a separate OEL report be submitted for Oceanside.

10/28/22 Update - OEL report was received on 10-28-22 and indicated that construction for Cape Meares Loop road crosses Coleman Creek upstream of their impoundment, which resulted in turbidity spikes and likely elevated organics. During construction the creek had to be diverted from its normal creek bed while the construction of the culvert and road base was being installed. Operators increased communication with construction crews, shut the plant down at night, and increased their coagulant dose to remove more organics.
