Details: I emailed Lynne Leisy, Corinne Clifton, Mike Murphy, and Megan Maloney. The Sept TTHM result was above the MCL, but the running annual average is still below the MCL due to a very low result in December 2017. The RAA is now 0.075 by my calculation (versus the MCL of 0.08 mg/L). So, no new violation and no public notice needed at this time, but given the results from the most recent 3 quarters, there will probably be a violation based on the annual average after the result from the next quarter is reported.

9/20/18 - The HAA5 result was posted today with the same outcome - the most recent result was over the MCL, but not the annual average.
Associated Alerts: CHEM8079 - 09/20/2018 - TOTAL HALOACETIC ACIDS (HAA5)

CHEM8074 - 09/18/2018 - TTHM
