The intrusion of sea water into fresh water aquifers, if it is occurring, would pose a serious problem for much of the outer cape regardless of whether it is due to changing geology, climate warming or both. For example, much of Provincetown's fresh water supply comes from wells on the property of the old coast guard station on Dewline Rd. in Truro. Should the salinity in that aquifer ever exceed safe limits, it would impact all of Provincetown's residents, not to mention the tourist industry.
Living in Truro, and being on a private well, this topic is obviously of interest to me. While my property is about 120 feet above sea level at last survey, the well is 130 feet deep.[/QUOTE]
The intrusion of seawater is happening and has been for some time. It's only a matter of time before Provincetown has to build a de-sal plant. My Grandfather was an engineer at the pumping stations on Beach Point and South Hollow after the Cold Storage closed. My Father in Law did pump testsw in P-town in the early to mid 70's. P-Town itself has all the water it needs, BUT, it needs to be treated.. My well is 25-28 feet deep in North Truro, Just about sea level.
