Sustainable Conservation, a San Francisco- and Modesto-based non-profit, has developed two key resources to inform on-farm recharge practices that are protective of water quality.
Protecting Water Quality
Over 600,000 Californians rely on nitrate-contaminated public supply wells for their household water needs. Many others struggle with contaminated groundwater from private, domestic wells – so the numbers are even greater. Recharging groundwater with water quality as a top priority will help the San Joaquin Valley – our nation’s premier farming region – manage through California’s inevitable droughts, ensure safe drinking water for farm-adjacent communities, and support a thriving agricultural economy as the region complies with the Sustainable Groundwater Management Act.
Achieving Groundwater Sustainability
Conceived in coordination with a diverse group of stakeholders and supported by a committee of San Joaquin Valley leaders, our nitrate management brief and water quality research paper compile the best available science with Sustainable Conservation’s decade-plus of on-the-ground experience with groundwater recharge. Replenishing aquifers by allowing surface water to seep into the ground has great potential to help water managers and agricultural communities achieve groundwater sustainability. However, when recharging on farm fields – a practice known in water management circles as Agricultural Managed Aquifer Recharge (AgMAR) – the potential mobilization of nitrate and salts is a serious concern, and this guidance suite presents field- and regional-scale considerations to protect community water quality.
Sustainable Conservation will share its new guidance widely with growers, water managers, community organizers, and our broader audience of friends and supporters through our various events, webinars, and publications.
