Lakehead-area residents live on bottled or boiled water.
Residents of a small water district near Lake Shasta face several more months living under a boil water advisory.
Residents living in the Sugarloaf County Service were told March 17 that they should boil their tap water before drinking it.
Minturn said the county has applied for a grant from the state to pay for repairing the well that supplies the district with water.
Surface water is getting into the well, tainting it with e coli.
A treatment plant kills the bacteria in the water, but the state Regional Water Quality Control Board said the process is unreliable and wants the well repaired, Minturn said.
In the meantime, the state Division of Drinking Water has approved another $25,000 to provide bottled water to low income residents in the district.
Minturn said the water system was built in the 1970s by a private developer, and the county took eventually took over operating it.
In comparison, in 2016 the Jones Valley County Service Area leaked 14.9 million gallons, or about 26 percent of the total 56.6 million gallons produced, according to the county.
Minturn estimated it would cost about $2.5 million to upgrade the entire Sugarloaf CSA water delivery system.
