Montevallo Water Works and Sewer

 

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Alabama Department of Environmental Management, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the EPA (July 2018 - September 2018), tap water provided by this water utility was in compliance with federal health-based drinking water standards.

This water utility has its own treatment plant or water supply, and also buys or otherwise receives some of its finished water from one or more public water utility systems to provide water for a part of its service area and customers. The list below includes the names of the supplemental water suppliers, with links to their water quality testing data.
- Chilton Water Authority
- Alabaster Water Board
- Calera Water Works
- Wilton Water Works

  • Bromodichloromethane

    cancer

    Bromodichloromethane, one of the total trihalomethanes (TTHMs), is formed when chlorine or other disinfectants are used to treat drinking water. Bromodichloromethane and other disinfection byproducts increase the risk of cancer and may cause problems during pregnancy. Click here to read more about disinfection byproducts.

    Health risks of bromodichloromethane in excess of health guideline

    The health guideline of 0.06 ppb for bromodichloromethane was proposed in 2018 by the California Office of Environmental Health Hazard Assessment as a one-in-a-million lifetime risk of cancer. Values greater than one-in-a-million cancer risk level can result in increased cancer cases above one in a million people.
