Tempe water violates EPA drinking-water standards:
People drinking water with high levels of (TTHMs) Total Trihalomethanes over many years can experience problems with their liver, kidneys and central nervous system, and may have an increased risk of cancer, according to the EPA website.
Total TTHMs, exceeded the maximum level of 80 parts per billion set by the Environmental Protection Agency and other agencies,
Test results from August 2016 to May at the west Tempe monitoring station were:
95 parts per billion on Aug. 11, 2016.
48 parts per billion on Nov. 8, 2016.
78 parts per billion on Feb. 2.
120 parts per billion on May, 9.
Federal law requires public disclosure when the average annual levels exceed the maximum standard. Tempe’s annual average was 85, or five parts per billion over the acceptable level.
