Denver Water is adjusting the pH level of its water
Denver Water is adjusting the pH level of the water it delivers to its customers as part of its long-term program to reduce lead contamination.
Denver Water currently delivers water with a pH level between 7.5 and 8.5, with a target of 7.8. The utility plans to increase its pH range to between 8.5 and 9.2, with a target of 8.8, according to 9 News.
The pH increase will begin next week and take a few days to a week to filter through the entire water system.
According to Denver Water, customers won't notice a change in taste or color but they might notice the water feels more "slippery."
The Lead Reduction Program was approved by state and federal agencies in December. The aim is for the higher pH to make the water less corrosive, which protects water-users who have plumbing in their home that contains lead.
The Colorado Department of Public Health and Environment alleges there are no health concerns from drinking water with a pH level of 8.8.
Denver Water services between 64,000 and 84,000 customer-owned lines with lead in them, reported 9 News.
The utility plans to replace those lead service lines with copper lines over the next 15 years. Another part of the plan is to provide free water filters to customers with lead service lines until the lines are replaced.
The entire program will cost about $500 million, according to Denver Water. Customers who will be part of the program will get information from Denver Water sometime in March, reported 9 News.
Residents can also request a water quality test for lead from Denver Water.
