AND OTHER CONSTRUCTION PROJECTS
§760-601 Declaration of Policy
Water is the single most significant resource which Suffolk County and its residents bear
the responsibility to protect and preserve. The County has long recognized the
importance of managing and protecting its water resources, has, over time, developed and
implemented groundwater and surface water management regulations and has instituted
changes to these regulations as evolving circumstances dictate. Water resource
management and protection are of utmost importance in the County, since residents rely
upon Long Island's Federally-designated sole source aquifer to supply their drinking
water needs. The surface water quality of Suffolk County's freshwater streams and
marine waters are directly impacted by policies to protect groundwater and drinking
water supplies, since groundwater provides stream base-flow and discharges to
surrounding coastal waters. Therefore, Suffolk County intends to facilitate the best
available wastewater management policies and technologies, to minimize and prevent the
impacts of water pollution from nitrogen and other constituents (such as pharmaceuticals,
personal care products, and volatile organic compounds) in sanitary wastewater to protect
public health and water resources. Suffolk County's intent is also to investigate the use of
wastewater management practices and technologies which permit the re-use of
wastewater, such as for agricultural irrigation and fertilization, in a manner that protects
public health and preserves water resources.
§760-602 Statement of Intent and Purpose
It is the intent and purpose of this Article to promote public health and safeguard the
water resources of Suffolk County. The County's drinking water must meet strict quality
standards to protect public health. Elevated levels of contaminants in the County's
groundwater raise serious concern. Many of the County's rivers, estuaries and bays are
impaired as the result of eutrophication. Nitrogen, which primarily emanates from
Subsurface Sewage Disposal Systems, Cesspools, and fertilizer impacts drinking water
supplies and causes hypoxia, harmful algal blooms, diminution of sea and shellfisheries,
and degradation of the County's protective natural infrastructure. Sea level rise is
projected to raise groundwater levels, thus further compromising on-site wastewater
treatment infrastructure.
Properly designed, sited, installed, managed, and maintained wastewater treatment
infrastructure provides a cost-effective and environmentally sound means of protecting
Suffolk County's water resources and improving public health protection. To promulgate
