I don't recall the figures, but Florida is one of the biggest producers of milk in the Southeast and has seen a dramatic increase in the number of dairy cows recently.

The ultimate cause is the increase in human population. The USA population has increased from 150 million in 1950 to 300 million today. Twice as many people taking a dump, twice as many drinking milk, twice as many cows producing the milk, twice as much water to wash away the manure, twice as much crap getting into the ground water.

Look for more closures year by year, with some becoming more closed more often for longer periods of time, until the Feds redefine "safe limit" and reopen the springs!

I recall a few years ago at one of the cave diving meetings: a state agent lectured explaining that the main source of water contamination was not septic tanks. It was chicken farms and septic tanks were near the bottom of the list and an insignificant source compared to the other sources.

Would like someone more informed than I to chime in and correct me as needed
