Total Trihalomethanes Water Quality Exceedance

East Valley Water District has Levels of Total Trihalomethanes (TTHM) Above the Drinking Water Standard

Our water system recently exceeded a drinking water standard. Although this is not an emergency, as our customers, you have a right to know what you should do, what happened, and what we are doing to correct this situation.

We routinely monitor for the presence of drinking water contaminants. Water sample results from April 14, 2016 to February 24, 2017 showed the annual average of Total Trihalomethanes levels at three locations of 92 parts per billion (ppb), 87 ppb and 84 ppb. This is above the standard, or maximum contaminant level (MCL), of 80 ppb.

There is no additional action necessary on your part.
