Public Notice 3/21/19

Notice of TTHMs above drinking water standards.

The above link leads to a notice of violation from the Department of Environmental Quality, Water Quality Division from the fourth quarter of 2018 and first quarter of 2019.  There is a detailed explanation of the violation in the report, however we want to be sure our customers understand that we are doing everything possible to provide safe drinking water.

What does TTHMs mean?

Trihalomethanes (THM) are a group of four chemicals that are formed along with other disinfection by-products when chlorine or other disinfectants used to control microbial contaminents in drinking water react with naturally occuring organic and inorganic matter in water.

How big is the violation?

The acceptable levels of TTHMs according to DEQ are 0.080 mg/L.  Our violation goes over the limit by 0.012 mg/L.  To put this into perspective, there are 1,000,000 milligrams in 1 liter of water.  That makes the level of the violation quite literally microscopic.  

It is also important to note that these numbers are taken on average, not per test.
