The island is hydrologically isolated and receives most of its fresh water from precipitation. There are 28 lakes and ponds on Nantucket, 12 of which are over 10 acres in size. Nantucket's water quality is fundamental to the health and welfare of its residents and to the island's economy. Rising nutrient inputs associated with increased development pose long-term threats to Nantucket's fresh and coastal waters.
- Improve the quality of marine waters and fisheries habitat by reducing nutrients entering waterways from point and nonpoint source pollution
- Support a comprehensive water resources management plan to address pollution from wastewater
- Work to develop a comprehensive wastewater management plan for the island, including sewer for Monomoy and a wastewater facility in Siasconset
- Identify key parcels of open space for acquisition and/or restriction to protect future water quality
- Ensure that the watershed has the necessary resources to gain measurable improvements in water quality
Recently, a study of the declining bay scallop population and water quality of Nantucket Harbor was conducted. These locations are currently being examined for growth rate and mortality. A study of the pollution sources to the harbor is also part of this study.
