Anne Arundel County proposes $70M aquifer recharge project amid water depletion concerns

On May 22, 2025, the Anne Arundel County Council convened to discuss critical budget allocations, focusing primarily on a proposed $70 million investment in aquifer recharge initiatives. This significant expenditure aims to address the county's groundwater depletion, a pressing concern as the region relies entirely on groundwater for its water supply.

The proposed project, set to unfold over the next eight to ten years, involves the construction of a demonstration facility that will inject treated water back into the aquifer. This method, already implemented in states like Virginia and California, is intended to replenish groundwater levels and extend the aquifer's lifespan. During the meeting, officials expressed optimism about the project's potential, citing successful pilot tests that have effectively removed harmful contaminants, including PFAS, from the water.

However, the council members raised questions about the project's economic feasibility and ongoing operational costs, particularly regarding the replacement of activated carbon used in the treatment process. The director of public works, Karen Henry, noted that while the initial capital investment is substantial, the long-term operational costs would need to be integrated into the county's budget. The council is currently evaluating the project's financial implications, especially in light of recent legislation that mandates additional treatment processes, potentially increasing costs.

The discussions also highlighted the collaborative efforts with the Maryland Department of Natural Resources (DNR) to conduct a regional aquifer study. This study aims to assess the depletion rates of the aquifer shared among several counties, including Calvert and Charles, which face their own water supply challenges. While Anne Arundel County is not in immediate crisis, officials emphasized the importance of proactive measures to prevent future shortages.

As the council deliberates on the budget, the aquifer recharge project stands as a pivotal initiative that could shape the county's water management strategy for decades to come. The outcome of these discussions will not only impact Anne Arundel County but may also set a precedent for neighboring jurisdictions facing similar water supply issues. The council's commitment to addressing these challenges reflects a broader recognition of the need for sustainable water management practices in the face of changing environmental conditions.
