Assistance Type: WATER QUALITY ALERT RESPONSE
Reasons: Disinfection Byproducts
 
Details: David Nordman called to report that their last round of DBP sampling had a result over the MCL for TTHM which was 0.0833 mg/l from sampling completed 2/15/22. I used the previous results to determine if they would exceed an action level or OEL for TTHM, however, it was determined that no action level or OEL was exceeded as follows: [(2 x 0.0833) + 0.0469 + 0.0676] / 4 = 0.070275 mg/l. I sent a follow up e-mail on 2/23/22 going over the response if they ever exceed an OEL and how the OEL is calculated. The alert was generated later that same day. No further action needed.
