Recommendations and requirements from the Ohio Department of Health


If elevated arsenic is detected in your water, your well will not be shut down. Installation of an arsenic treatment system is highly recommended, but is not required. You may wish to consult your health-care provider about potential impacts to your family’s health based on your level of arsenic exposure through water used for cooking and drinking.

The purchase and installation of treatment equipment to remove arsenic from your private water well is not only a big financial investment in your water system, but is also the primary line of defense to remove or lower the arsenic in your water supply. The lowest price unit may not always be the best choice. Be an informed consumer. There are a few steps that must be followed when installing an arsenic treatment system:

  • For whole-house (Point-Of-Entry) treatment systems, you must obtain a permit to alter your water system from the local health department. It is also necessary to use a contractor that is registered and bonded by the Ohio Department of Health. This assures that the system is approved for safety and effectiveness, and that it is installed correctly. These requirements do not apply to single-tap (Point-Of-Use) systems, but installation should follow local plumbing codes.
  • It is recommended that you obtain at least two price quotes that completely describe all installation, testing, and maintenance costs. A service contract may be necessary for some systems, so it is important to compare all costs for installation and long-term maintenance.
  • After the arsenic removal system is installed, contact the local health district. A sanitarian will schedule a time to inspect the system and collect a water sample for testing. The sample will be analyzed for arsenic by a certified lab, and the results will sent to you the by the local health department.
  • It is important to perform all maintenance on your system that is required by the manufacturer. Many treatment units will require that media be replaced or flushed and proper maintenance is critical to ensure that your treatment unit continues to effectively remove the arsenic from the water.
