LANCASTER - Notices have been mailed to city water customers informing them of a minor non-compliance with treatment standards.
The notice states that during a monitoring of contaminants, the percent removal of Total Organic Carbon in the water met a ratio of .73 when the "rather complicated goal" is 1.00.
The notice states that while Total Organic Carbon has no health effects, it can provide a medium for the formation of disinfection byproducts (DBP's) such as Trihaolmethanes and Haloacedic Acids. Both can lead to adverse health effects including cancer.
Meleeva Chamberlain with the Kentucky Division of Water said checking for TOC's is something that water systems have had to monitor for, according to regulations passed by the Environmental Protection Agency in 2002.
