Abstract

Freshwater availability is a serious resource concern, due to the increasing needs of a rising population. This issue is especially critical in coastal regions both due to supplying the increasing number of people migrating to these areas, and the higher potential for saltwater intrusion into groundwater supplies as water demands increase. This study assesses the degree of saltwater intrusion on San Juan Island, Washington, including its extent, contributing factors, and the implication for the water resource availability. The analysis projects water resource issues on the island based on the extent of saltwater intrusion, population fluctuations due to tourism, projected island population changes, and the potential impact these will have on groundwater resources and freshwater supply. The level of intrusion is increasing and will affect future water availability on the island.

Influence of saltwater intrusion, climate, and population changes on the ground water supply of San Juan Island.
