Three Forks details lead-line replacement plan and celebrates high-yield Well 2C
Summary
City engineers told the council that Three Forks identified 2 known lead service lines, 62 galvanized lines and 80 unknowns and must meet EPA rules to replace contaminated lines within 10 years starting Jan. 1, 2028; the city also reported that newly drilled Well 2C produces about 200 gpm with good water quality.
City engineers gave the Three Forks City Council a technical update on the municipal water project on Dec. 10, highlighting federal lead-service-line rules and a newly completed supply well.
"Within the existing water distribution project area there is one known lead line, some unknowns and some galvanized lines which also require replacement," City Engineer Susan Hayes told the council. She said the city’s inventory shows 2 known lead lines, 62 galvanized lines and 80 unknowns. Hayes said the Environmental Protection Agency’s new lead rule requires replacement of all lead and galvanized lines, including connectors, within 10 years starting Jan. 1, 2028, and that DEQ will require sampling and monitoring of known lead sites effective that date.
Hayes said the city will add specific bid items to replace known lead and galvanized services while crews are excavating streets for the larger distribution project and will pursue funding, including State Revolving Fund (SRF) resources. She added the city plans to provide water-filtration pitchers to households served by known lead or galvanized service lines.
On supply, Hayes reported that contractor O’Keefe drilled a public water supply well (Well 2C) that returned about 200 gallons per minute and showed acceptable lab results for gross alpha and uranium. "We have the water quality analysis back and are getting 200 gallons per minute (gpm) with good quality!" she said, and noted a contract amendment for connecting infrastructure and a backup generator will be brought to council in January.
The council discussed next steps for inventorying unknown services, coordinating funding and determining a replacement schedule that meets the EPA/DEQ deadlines.
