Storm Purges

It's been four years since Superstorm Sandy poured down on the northeastern U.S.  Now, major hurricanes simultaneously threaten to cause disasters in both hemispheres. Despite Matthew's menacing track forecast, there is a good chance it will stay out at sea. Either way, it looks like much of the east coast is in for a deluge. One of the greatest impacts caused by Sandy and many other extreme rain events is one we seem to forget too quickly afterwards - overflowing of sewage treatment plants. The cumulative result,  in connection with Superstorm Sandy, was discharge of some 11 billion gallons of raw sewage to our environment. While 7 million gallons is enough to push me to take desperate measures, billions of gallons may drive me to despair.

Our wastewater treatment infrastructure, like so much else in our country, has not been maintained or renewed enough to keep pace with a growing population. Add to that the stress of climate change, and there is bound to be an increase in failures. Rising sea levels, even from a storm surge, is particularly culpable.

Inundation also affects septic systems by raising the water table well inland from the shore, causing degradation of septic system performance - all the more reason to transition to humanure composting in lieu of sewage and septic solutions. Septic systems, for various reasons, pollute proportionally more than sewage overflow incidents, but for my money, humanure composting is better than either.

How Quickly Things can Change

In little time, Matthew went from a tropical storm to a category 5 hurricane. By late next week, peoples' lives on this coast may be dramatically interrupted. When these storms track west of the Chesapeake Bay, the storm surge has been reported as high as 15 feet in one long ago incident. The flood hazard estimates for the Calvert Cliffs nuclear plant use a maximum probable surge of 27 feet (the plant survives, but so long Norfolk, Annapolis, and Baltimore).

Storm surge isn't the concern for my home, but a major hurricane hit would possibly take off the roof or knock down walls. We would not be in the house at that point, having evacuated to a shelter or to the hinterlands about a day ahead of the storm. More than likely, we would be dealing with something less than a category 3 hurricane this far up the bay, so my choice would be to ride it out (though, this time, with all of the saturated ground, toppled trees would be a bigger problem than usual).

Time to start going through the hurricane checklist. Hopefully, track forecasts will allow me to put such preparations aside short of having to shift to the evacuation checklist.
