This is of concern in our area as coastal agriculture and wells are affected by increased salinity due to ocean rise along with well overdrafts, not to mention coastal erosion putting homes at risk.

The impacts of climate change are likely to worsen many problems that coastal areas already face. Shoreline erosion, coastal flooding, and water pollution affect man-made infrastructure and coastal ecosystems. Confronting existing challenges is already a concern. Addressing the additional stress of climate change may require new approaches to managing land, water, waste, and ecosystems.

From 1964 to 1997 the Pajaro Valley groundwater basin is thought to have lost over 300,000 acre-feet of freshwater storage, two-thirds of which has been attributed to saltwater intrusion (11). The current rate of saltwater intrusion for the Pajaro Valley basin is estimated at 100 to 250 feet per year (30-73 m/yr), meaning that saltwater is moving inland this distance each year, and contamination can currently be seen seven miles inland in the 180 foot aquifer.
