Ground-Water Quality
The quality of ground water in Butte Valley is generally suitable for most uses.
Dissolved-solids concentrations in the water rarely exceed 500 milligrams per
liter. However, owners of a few wells completed in the volcanic rocks report
that the water has a sulfur odor, and sodium concentrations exceed 50 milligrams
per liter in water from a few wells completed in these rocks. Shallow wells
completed in the lake deposits about 4 miles southwest of Dorris produce highly
mineralized water that exceeds 500 milligrams per liter dissolved-solids
concentrations probably because the water that recharges the aquifer in that
area becomes mineralized while percolating through the overlying playa deposits.
