Freeway Well Feasibility Study
For almost 30 years, the City used the freeway well to provide approximately one million gallons of water per day to its customers. However, in the 1980’s City staff discovered during routine water quality testing that groundwater below the site had become contaminated with volatile organic compounds (VOCS) from chemicals and solvents used at nearby properties in the area. The Freeway Well has not been used since that time.
For many years, Santa Rosa Water has wanted to study groundwater resources below the Freeway Well and determine if it’s feasible to rehabilitate the well or replace it, but the City has not had the resources to do so. The State Water Resources Control Board expressed interest in aiding the City and has awarded a grant to help fund the Freeway Well.
The project is currently underway and anticipated to be completed by February 2021. For more information, please see the documents and timeline below and contact information posted to the right.
