SANDY — Hundreds, if not thousands of emails between Sandy City employees related to the water quality debacle were released to KSL Wednesday following an open records request.

The emails show that Sandy City was warned that the water supply could be contaminated with lead and copper a full week before they told residents.

One email was sent at 11 p.m. on Friday, Feb. 8, to Tom Ward, Sandy’s utilities director. He is now on administrative leave.

“Mike said there was a report of a kid peeing in a toilet and the water turning blue. As in the attached report, my thought is that it is from copper that was stripped from the interior plumbing. This is why ongoing metals testing is important. The affected homes could have elevated levels of lead and copper.”

The email came from a state environmental scientist.

Despite this warning, Sandy City only warned residents about an excess of fluoride in the drinking water.
