Notice of Future Design-Build Project

March 22, 2021

In April of this year, the City of Anaheim (Anaheim) will solicit the services of a design-build entity to install groundwater treatment systems to comply with recent State regulations for PFAS chemicals. The Groundwater Treatment Program (GWTP) will be done in two phases, Phases A and B.  Phase A of the project was advertised last year and will be awarded in April 2021. The current solicitation will be for Phase B of the project, which includes five new groundwater treatment sites with an estimated budget of $35-$45 million. In total, the PFAS program has an estimated budget of $85 - $100 million. Phase B may be funded using Water Infrastructure Financing and Innovation Act (WIFIA) funding.


Under a new California law, drinking water producers are required to test for perfluorooctane sulfonate (PFOA) and perfluorooctanoic acid (PFOS). In February of 2020, the Division of Drinking Water (DDW) lowered the response levels of PFOA and PFOS to 10ppt and 40ppt respectively. Owners of water systems that exceed the respective response levels are required to remove the impacted source water from service, provide treatment, or notify their respective customers. In response to the new ordinance, Anaheim removed 14 of 19 wells from service, or approximately 75% of its groundwater supply, and is supplementing the supplies with more expensive imported water.

Project Scope

The groundwater treatment plants design-build project will include the construction of localized wellhead treatment and centralized groundwater treatment with their respective conveyance systems. The treatment goal is to lower the concentration of PFOS and PFOA to 2ng/L or less, which is the current limit of analytical methods and considered to be non-detectable.
