Refinement of the 1993 Basin Management Plan for the Pajaro Valley in Monterey County California
The Pajaro Valley Water Management Agency (PVWMA) must deal with issues of both water supply and water quality. Managing water resources for agricultural and municipal users requires maintaining a reliable water supply to meet growing demands while preventing ground-water overdraft and the related degradation of water quality. Important regional water-quality concerns include increased nitrate concentrations and seawater intrusion. To protect the quantity and quality of the ground-water supplies, the PVWMA has implemented a plan to prevent further seawater intrusion. In order to evaluate how these activities can be conducted most effectively, it is necessary to improve the understanding of the hydrogeology and geochemistry of the water resources in the Pajaro Valley.
The Basin Management Plan (BMP) developed for the Pajaro Valley in 1993 (Montgomery Watson, 1993) continued to be refined to help provide reliable water resources. In order to effectively implement the BMP, it was necessary to identify the parts of the aquifer systems that were not in connection with sources of recent recharge, the parts of the aquifer system that are being actively recharged in the coastal regions and represent the renewable resource, and the sources and movement of the natural and artificial recharge and seawater intrusion.
