Did you know that Murray City School District has conducted two independent samplings (2020, 2017) of culinary water in our facilities and each demonstrated compliance within Environmental Protection Agency (EPA) standards.  

In 1991, the EPA published a regulation known as the Lead and Copper Rule (LCR). The LCR established a requirement for public drinking water systems classified as either community or non-community non-transient to routinely monitor for lead and copper.

Also identified in the LCR are action levels for elevated lead and copper. An action level is a threshold above which a water system must take steps to ensure safety and protect public health. For lead and copper, the action level is deemed to have been exceeded when more than 10% of the samples tested during a collection period show concentrations at or above the 15 ppb for lead and 1300 ppb for copper and is called a 90th percentile exceedance.

A sample collection exercise, performed most recently on January 29, 2020 included first draw water samples, collected from a drinking fountain and a kitchen sink in all MCSD buildings. In buildings with no kitchen, the second sample was collected from a break room or bathroom sink. 

Samples were then analyzed by American West Analytical Laboratories of Salt Lake City, Utah. The analytical results for all samples collected were significantly lower than the EPA’s regulatory “action” level of 1.3 mg/L for copper and 0.015 mg/L for lead.

This is consistent with the sample done by the Utah Department of Environmental Quality (DEQ) in 2017. You can read about the DEQ report here.
