Water
GRANTVILLE — The “water issue” residents keep asking about is not a single boil-water crisis. It is a stack of official findings: the city buys all of its drinking water from Coweta County, the 2025 Consumer Confidence Report shows the system went over the federal limit for total trihalomethanes (TTHM) during the year, the city says flushing and pipe-system changes brought it back into compliance in October 2025, and Georgia’s environmental agency still has the state under a Level 1 drought response that mainly means conservation messaging. This tracker is the Ledger’s living file on that story.
Background
Grantville’s water system (ID GA0770001) does not claim to treat raw river water for the whole town in the CCR’s source description. The report says the city purchases finished water from Coweta County and delivers it through the city’s own pipes and tanks. When that purchased water sits too long in parts of the local network — what the CCR calls water aging — disinfection byproducts can climb.
Trihalomethanes form when chlorine used to kill germs reacts with organic matter. The EPA’s Maximum Contaminant Level is 80 parts per billion, measured as a running average. The 2025 CCR lists a highest level of 88.9 ppb (range 52.7–88.9) and marks a violation. The report’s required health language warns that drinking water above the MCL over many years may raise risks for the liver, kidneys, nervous system and cancer, and that vulnerable people should ask a doctor about drinking the water. That is the federal notice language, not a Ledger medical diagnosis.
The city’s Utilities page still posts the public notices it sent when quarterly averages crossed the line (including notices dated around March, June and September 2025). Those notices are how systems tell customers a limit was exceeded. They are separate from a boil-water advisory. Coweta Water’s public sheet says boil-water alerts usually follow pressure drops below 20 psi, often after a main break, until lab samples clear.
On April 27, 2026, Georgia EPD declared a statewide Drought Response Level 1. Under EPD’s rules, systems must run a public information campaign. Outdoor watering between 4 p.m. and 10 a.m. remains allowed at Level 1. Drought messaging is about supply and conservation; it is not the same finding as the TTHM table in the CCR.
Money sits underneath the pipes. The city’s FY2025 audit, summarized in the Ledger’s utility-bill story, shows water and sewer billing about $1.39 million and operating costs about $1.70 million — an operating loss of roughly $311,530. Capital help from SPLOST has moved onto the books in prior years; that is not the same as day-to-day rates covering operations. Posted rate schedules live on the city site.
Latest developments
Nov. 5, 2026 — The Ledger opened this tracker after residents said they still did not understand what “the water issue” was. The city’s posted 2025 CCR and Utilities notices remain the primary public documents; the Ledger has not retested taps. (CCR PDF; Ledger background summary: 2025 CCR / TTHM; Utilities)
February 11, 2026 (CCR footer date) — Grantville’s 2025 Consumer Confidence Report records the TTHM MCL exceedance for calendar 2025, attributes it to distribution aging, and states that flushing plus distribution changes restored compliance in October 2025. HAA5 is listed without a violation in the same table. Lead and copper sampling shown for August 2024 does not show an MCL violation in that CCR table.
April 27, 2026 — EPD declares statewide Level 1 drought response; the city posts the notice on its Utilities pages. EPD later kept Level 1 in place through summer update briefings described on its drought-management page.
March–September 2025 — City posts successive public notices of TTHM violations on the Utilities page as quarterly averages require them.
What it means for residents
If you are on city water, the water in your tap is Coweta-treated water moved through Grantville’s system. The 2025 overage was a compliance finding about disinfection byproducts, not proof of a current boil-water order. The city says the fix worked by October 2025; residents who want proof beyond the CCR should ask the Water Department (770-583-2289, listed on the CCR) for the latest quarterly results and watch for new notices on grantvillega.org/utilities.
Drought Level 1 mainly asks people to take conservation seriously; it does not, by itself, ban daytime outdoor watering under EPD’s published Level 1 rules. A separate boil-water alert would come from the city or Coweta Water if pressure or contamination rules trip — follow those alerts if they appear.
When something new happens — a fresh EPD notice, a consent order, a rate hearing, a council vote on water capital — the Ledger will publish a regular news story and add a dated paragraph here. Tips and documents: tips@grantvilleledger.com.
Unverified / open: Whether every quarter after October 2025 stayed under the MCL; whether Georgia EPD has a formal consent order beyond the public notices (none found on the city Utilities page in the Ledger’s check); neighborhood-level sample maps not in the CCR PDF.
