Water users in Tracy City were put on notice via a mailout that the municipal water supply exceeded the contamination levels for Trihalomethanes.

The contamination took place between July 1, 2015 and June 20, 2016.

The contamination was calculated to be 0.084 mg/L, exceeding the maximum levels of 0.040 mg/L.

Trihalomethanes (aka THM) are used in industry as solvents or refrigerants and considered pollutants. They can even be considered carcinogenic. 

The Tracy City Water System says the THMs are byproducts of their disinfection process.

In the mailer, the TCWS said:

Some people who drink water containing Trihalomethanes in excess of MCL over many years may experience problems with their liver, kidneys or central nervous systems, and may have an increased risk of getting cancer.
