Read, below, how the city and their engineering firm were concerned about the mining well even before it went in for three reasons: potential for salt water intrusion, water quality, and if there was sufficient water quantity to meet these needs.
According to USGS, we don't really know how much water we have left in our area:
"...there is no long-term ambient groundwater monitoring network in the study area, and data from the short-term (March 2007–September 2008) monthly monitoring network established for this study are insufficient to evaluate water-level trends relating to long-term changes in groundwater storage. The Tacoma-Pierce County Health Department long-term (1996–2006) groundwater monitoring report (2007) identified “possible declining water levels” in 23 of 70 active public-supply wells in the study area."
The study area, WRIA 12, includes DuPont public-supply wells.

The mining well has been withdrawing 40,000,000 (million) gallons per week, since 1995.
How much water is really left for the residents of DuPont?
