Water and Wastewater

Hanson’s engineers, planners, scientists and allied professionals can help you with your water and wastewater projects. From a water main extension to a complete wastewater treatment plant, our skilled team can meet the challenges of aging infrastructure, facility expansion or growth into new and undeveloped areas. We offer comprehensive services, working to help you achieve your goals while complying with federal, state and local environmental requirements.

PFAS mitigation measures

We can help you navigate the U.S. Environmental Protection Agency's regulations regarding polyfluoroalkyl substances (PFAS) by assisting public water systems (PWS) with sampling, treatment and compliance solutions and implementing mitigation measures. Mitigation can include:

  • consolidating with neighboring PWSs whose sources do not have PFAS issues
  • decommissioning wells or intakes that have PFAS issues
  • pursuing alternative sources of supply that do not have PFAS issues
  • implementing enhanced treatment technologies for finished water, including:
    • adsorption through activated carbon filtration
    • ion exchange utilizing a selective resin
    • reverse osmosis

Hanson can also assist communities with the application process for revolving loan funds, including potential grants and principal forgiveness for the PWSs that qualify.
