Hartford Municipal Water Works

 

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Kentucky Department for Environmental Protection, 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 serious violation 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.

    Includes chemicals detected in 2015 for which annual utility averages exceeded the federal Maximum Contaminant Level (MCL); chemicals detected in 2015 for which annual utility averages exceeded an EWG-selected health guideline established by a federal or state public health authority; radiological contaminants detected between 2010 and 2015.

  • Atrazine

    harm to the developing fetus

    Atrazine is a herbicide commonly detected in drinking water that comes from cornfield and other agricultural runoff. It is a hormone disrupter that harms the male and female reproductive systems of people and wildlife.

  • Haloacetic acids (HAA5)

    over legal limit

    Haloacetic acids are formed when disinfectants such as chlorine are added to tap water. The group of five haloacetic acids regulated by federal standards includes monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monobromoacetic acid and dibromoacetic acid.

  • Radiological contaminants

    cancer

    This utility detected Radium, combined (-226 & -228).

    Radiological contaminants leach into water from certain minerals and from mining. Drinking water contamination with radioactive substances increases the risk of cancer and may harm fetal development.

  • Total trihalomethanes (TTHMs)

    cancer

    Trihalomethanes are cancer-causing contaminants that form during water treatment with chlorine and other disinfectants. The total trihalomethanes group includes four chemicals: chloroform, bromodichloromethane, dibromochloromethane and bromoform.
