Battle Creek officials announced promising news regarding water quality, revealing that total trihalomethane (TTHM) levels are improving. While a drinking water standard violation remains in effect for residents in Battle Creek, Springfield, Emmett Township, and parts of Penfield Township, recent testing shows that TTHM levels no longer exceed the federal maximum containment level of 80 parts per billion.
Quarterly testing from May indicates a positive trend, although the running annual average (RAA) for TTHM still exceeds the maximum level due to earlier elevated readings. These past samples continue to affect the RAA until they are replaced by consistently lower results.
City officials are optimistic, noting that corrective actions are making a difference. Key efforts include adjusting treatment processes to minimize TTHM formation, completing an annual hydrant flushing program to clear out older water and sediment, and increasing sampling at the Verona Well field. Additionally, quarterly operational evaluations are being conducted to assess factors influencing TTHM levels, and aging wells at the Verona Well field are being replaced to enhance long-term water quality.
Residents impacted by the violation have received letters from the city's water division outlining the latest results and ongoing efforts to improve water quality. This information is also accessible on the city’s website, battlecreekmi.gov. As these initiatives continue, officials expect TTHM levels to decrease further, ultimately bringing the water system back into compliance.
