A blown fuse on Wednesday led to a malfunction in the ultraviolet (UV) light disinfection system at the City of College Station’s Carter Creek Wastewater Treatment Plant, causing the release of an estimated 347,000 gallons of non-disinfected wastewater into Carter Creek.
Water quality sampling upstream and downstream of the discharge point have not detected any contamination.
Between 2:10 p.m. and 3:25 p.m., the ultraviolet light bulbs were not illuminating and wastewater was not disinfected before discharge. The system returned to normal operation after the fuse was replaced.
No domestic or public drinking water wells or surface water intakes are known to be within a half-mile of the spill. However, the City of College Station provides the following precautionary statements for anyone who may come into contact with non-disinfected wastewater as a result of the discharge:
1. Persons using private drinking water supply wells located within a half-mile of the spill site or in the potentially affected area should use only water that has been distilled or boiled at a rolling boil for at least one minute for all personal uses including drinking, cooking, bathing, and tooth brushing. Individuals with private water wells should have their water tested and disinfected, if necessary, before discontinuing distillation or boiling.
2. Persons who purchase water from a public water supply may contact their water supply distributor to determine if the water is safe for personal use.
3. The public should avoid contact with waste material, soil, or water in the area potentially affected by the spill.
4. If the public comes into contact waste material, soil, or water potentially affected by the spill, they should bathe and wash clothes thoroughly as soon as possible.
