Details: SUMMARY: Single sample elevated TTHM DETAILS: Left message for Alan regarding December monitoring results for TTHM. Although the single sample results was elevated, the running annual average (RAA) incorporating the previous 3 quarter concentrations of TTHM was below the MCL - calculated value was 0.0625 ppm, RAA MCL for TTHM is 0.08 ppm - so this is not an MCL violation. In my message I questioned whether there was anything unusual happening with regards to chlorine residuals or incoming NTU/TOC that could explain the elevated TTHM. ACTION NEEDED: Wait to hear from Alan.
 
Associated Alerts: CHEM5212 - 01/05/2012 - TTHM
