Good taste steered the Kerrville City Council to pursue the more expensive of two options to solve a problem that has the city’s water supply under state scrutiny.
The council unanimously directed staff Tuesday to further pursue the granulated activated carbon filtration to fix its issue with total trihalomethanes — or TTHMs — a byproduct of the chlorination process.
Under the Safe Drinking Water Act, the average concentration of TTHMs in a water distribution system may not exceed .080 micrograms per liter. Last year, city sampling showed a running average result of .094 and .095 micrograms per liter.
Kerrville Assistant City Manager E.A. Hoppe reminded the council that the city is under a Texas Commission on Environments Quality enforcement action regarding TTHM.
“We’re at a critical juncture tonight in getting direction from you for the next phase … determining which path you would like for us to go on,” he said.
With that direction given, the city might — if the council accepts the final engineering report — be ready to seek bids for the project in mid-2018.
