As pollution worsens on Cape Cod, some are investing hopes in a new type of septic system

BARNSTABLE — For years, pollution from septic systems has spawned algae blooms,toxic bacteria, and a putrid scum coating the waters of Cape Cod, destroying vitalecosystems, contributing to coastal erosion, and harming tourism.

“The water that comes from this system is treated to such a high degree that it’s almostpotable,” said Zenas Crocker, executive director of the Barnstable Clean Water Coalition,which has been overseeing a pilot project here that is installing the new septic systems atno cost to homeowners. “We see this as having an easier runway for expansion thansewers; they can be built more quickly and lower tax bills.”
The pollution has also spawned billion-dollar plans to dig up roads and install extensivesewer systems that local officials say is essential to cleaning up bays, estuaries, and pondsfrom Bourne to Brewster.
