The water supply for the Lummi Indian Reservation, in Whatcom County, comes from the ground-water system in the area. The Lummi Indian Nation is concerned that the present rate of ground-water use exceeds the rate of recharge to the ground-water system and rates of withdrawal are anticipated to increase. There is also concern that the present rate of withdrawal has caused seawater intrusion into parts of the Reservation and that increased rates of withdrawal will induce further intrusion.
To help the Lummi Indian Nation address their concerns about the water supply, the USGS is studying the framework and characteristics of the ground-water system and the quality of the water. The study includes defining the water-bearing and confining units of the ground-water system, measuring water levels, and determining the general water type and concentrations of chloride, an indication of possible seawater intrusion.
