Chemist David Stiles performs a heterotrophic plate count test on an incubated tap water sample from Monday on Feb. 5 at the Danville Water Treatment Plant. Stiles explained that if the tap water sample from Monday was toxic then bacteria colonies would be unable to grow in the incubated sample.

Statement from the city of Danville:

Danville Utilities has received a second set of test results. These results are from treated water samples collected on Tuesday, and they show Danville’s water is safe to drink.

The treated water samples were collected by Danville Utilities from the city’s reservoirs. Those samples were sent to a Virginia certified private lab. The lab tested the samples for the presence of arsenic, cadmium, chromium, copper, lead, selenium and zinc.

The lab found no detectable level of arsenic, cadmium, chromium or selenium. Low levels – all below public health standards for drinking water – of copper, lead and zinc were found.

Danville Utilities continues to collect raw water and treated water samples. Results will be made available to the public when they are received.
