You'd think ponds on Nantucket would be safe, with the island so far out in the ocean. But no. Look what's happening to Hummock Pond...

Read more about how septic system runoff is harming Hummock Pond. We can prevent this from happening at Hawksnest, if we act together now.
At Long Pond, in 2007 they were proposing alum treatment to stop the algae blooms and fish kills. The treatment was to cost $420,000--yet they didn't even have a management plan for how to prevent the nutrients from accumulating again. Just think what we could do with $420,000 spent on prevention of the problem, instead of closing the barn door after the horse has escaped.
At Hawksnest, let's spend a little now on prevention, before the problem occurs.
I'm involved at Hawksnest, because I've seen where we could be headed. I now live in southern Wisconsin, where most of our lakes and ponds are sick, like the ones in the aerial photos below:
Runoff after a storm dumps sediment and nutrients into Lake Mendota. This is now starting to happen on a small scale at Hawksnest Pond.
The nutrients from storm runoff and from septic systems lead to algae blooms. Once this happens, most nutrients stay put. The lake cannot be cured. This disease of lakes is called "eutrophication."
Some of our small ponds get this bad, covered with duckweed.
So, Harwich, which kind of pond do you prefer?
The three examples above...? or, Hawksnest as it still is...
Get involved now. Help organize a friends group for Hawksnest.
