Third party test results of Claremore drinking water show a mixed bag.

This month, copper and lead were found to be within safe-to-consume levels based on Environmental Protection Agency standards.

However, in August, tests conducted at Will Rogers Junior High and Claremore High School found byproducts of disinfectants above the maximum contaminant level.

Tests were performed by Accurate Environmental Laboratories, which is certified by the Oklahoma Department of Environmental Quality.

Lead and Copper

For lead and copper testing, samples were taken from 36 locations across the city.

In each location, amounts of lead were found to be below a practical measurable level, less than five micrograms per liter.

Copper ranged from being below a practical measurable level, less than .01 milligrams per liter to 0.6 milligrams per liter.

Both results are well within the levels the EPA considers safe-to-consume.

Disinfectant byproducts

In August , tests conducted at Will Rogers Junior High and Claremore High School showed that the number of trihalomethanes, a chemical created by the mix of disinfectant and organic material in drinking water, was slightly above the maximum contaminant level set by the EPA.

The maximum contaminant level for total trihalomethanes is 0.080 milligrams per liter.

The results at the junior high and high school were 0.0859 and 0.0828 respectively.

Oklahoma Department of Environmental Quality Communications Director Erin Hatfield said, “Some people who drink water containing trihalomethanes in excess of the maximum contaminant level over many years may experience problems with their liver, kidneys, or central nervous system, and may have an increased risk of getting cancer.”

Response to results

In response to the test results, the city of Claremore posted the following statement to Facebook:

“We’re pleased to report that upon consistent testing of our water, all samples continue to be independently verified as complaint. In accordance with water sampling required by the Environmental Protection Agency, we tested this week for lead and copper. All samples were compliant and there was no lead detected. Our water has always been, and continues to be, safe to drink.”
