Yearlong pumping test will help define aquifers across Kitsap Peninsula

An unprecedented yearlong pump test of a deep water well in Central Kitsap is expected to provide a wealth of new information about our underground water supplies.

The 900-foot-deep well, off Newberry Hill Road, will be pumped continuously for a year, drawing water at a rate of 1,000 gallons per minute. Drawdown effects of the high pumping rate will be measured in 56 other wells — including those operated by Silverdale Water District, Kitsap Public Utility District, the city of Bremerton, North Perry Water District, Naval Base Kitsap-Bangor and others.

The pump test is designed to better define the extent of aquifers throughout Central Kitsap while increasing the accuracy of a groundwater model developed to predict water supplies across the Kitsap Peninsula.

“This is going to be one of the best data-gathering tests,” said Joel Purdy, hydrogeologist for Kitsap Public Utility District. “Hydrogeologists dream of doing this kind of aquifer test.”
