The Joint Waste Water planning Committee, formed in the fall of 2014 and comprised of town officials from Oak Bluffs and Tisbury, is researching (1) any and all new technologies (including sewering) that will work to reduce or even eliminate the introduction of nitrogen into the Lagoon Pond watershed, (2) treat/remove nitrogen already in the Pond and (3) slow/stop the introduction of nitrogen in the ground water already on its way to the Pond.
While sewering is the best option for stopping introduction of new nitrogen into the watershed, it is the most expensive option and will be a “hard sell” to the property owners.
As with most technology in the world, there are new and improved systems being developed to treat waste water on-site and must be considered. Some of the newer systems are being tested on Cape Cod and remember; Cape Cod is far ahead of the Vineyard in dealing with nitrogen overloading and research into the “options” available. The Point® System is one such system. Initial research shows that 98% of the nitrogen can be removed with this alternative on-site septic system that relies on “oxidation of septic ammonia to nitrate with subsequent anaerobic, carbon-mediated oxidation to nitrogen gas”. While that is a “mouthful” of scientific jargon, in plain English, the system is being built to convert nitrates into non-toxic nitrogen gas that dissipates into the air and not into the soil. Treating/removing nitrogen already in the Pond is a fairly new concept. One new technology being developed is the Quantum Ozone UV/ION In-Situ Storm Water System™.
