Ive heard that if the Aquifer goes low, salt water would intrude into the fresh water areas. Is that true?
The US Fish & Wildlife Service includes the possibly of salt water intrusion into the fresh water zone among the reasons that some species have been listed as endangered, but I have never talked to a hydrologist who felt that saline water intrusion was anything to be even remotely concerned about. During dry times or when the Aquifer is drawn down to low levels, very small volumes of salt water might intrude along the interface between the fresh and saline sections of the aquifer, but the saline water would be flushed back out again quickly when water levels rose.
