Details: SUMMARY: Alert response for TTHM DETAILS: Alert for TTHM of 0.103 issued on January 23, 2009. Calculated RAA for TTHM at this facility using 0.103, 0.0376, 0.0190 and 0.0248 to get value of 0.0461. This value is below the MCL of 0.08 and also below 80 percent of the MCL 0.0640 and therefore is not a violation. Owner informed me that they had a problem with the injection pump for the disinfection process and that this likely explains jump in TTHM during the fourth quarter of 2008. They have since corrected the problem. ACTION NEEDED: None at this time.
