Dillon waiting on state direction to address elevated levels of lead in drinking water

The town of Dillon discovered heightened levels of lead in the drinking water of seven of 20 sites tested earlier this year. Officials are waiting on state approval to change the town's water treatment process to help address the "aggressiveness" of the source water, which is leeching lead from outdated pipes and fixtures.

Dillon is still in the wait-and-see stage of determining what to do about elevated levels of lead discovered in water at some of the town’s testing sites. 

In May, the town discovered heightened levels of lead in some of the town’s testing sites set by the Colorado Department of Public Health and Environment. Dillon’s source water is clean and completely safe to drink, but because it’s so aggressive its able to leech materials off of older fixtures containing leaded solder installed in homes prior to 1987. 

Dillon officials said they wanted to add soda ash — essentially baking soda — to the water treatment process to increase pH levels, alkalinity and harness to the water to reduce aggressiveness and leeching of older fixtures. Though any changes to the water treatment process have to go through the state. 

Mark Helman, Dillon’s chief water plant operator, said the town has submitted numerous tests and data to the state, and is currently waiting to hear back. 

“We’re kind of in a holding pattern until that happens,” said Helman. “It’s just collecting data for the state so they can evaluate. They’ll look at that and respond here soon to give us some direction.
