Conducted by the New York State Department of Health Focused on evaluating the effects of synthetic detergents on the groundwater’s quality. Recommendations Sewering of Nassau and Suffolk County would be an effective method of treating domestic sewage rather than on-site septic systems. Only 25% of Nassau had been sewered with an additional 40% planned to be installed; Suffolk County only 4% of the population was sewered. A substantial time period must elapse before sewer construction is advanced to the degree that adequate protection will be provided to the groundwater source. Encourage the soap and detergent industry to intensify research on developing suitable synthetic detergent products. Public water supply facilities should be extended to replace individual wells to ensure the water quality. A program of groundwater quality monitoring should be carried out by NYS, Nassau, and Suffolk Counties

1982 FANS Study Three alternative approaches to mitigate the impacts of sewering. No action Complete Mitigation Intermediate Mitigation No action Acceptance of the adverse environmental impacts projected to occur as a result of sewering. Complete Mitigation Fully mitigate all environmental impacts from sewering. Estimated cost $100 million Technology would be to augment streamflows with highly treated wastewater at the headwaters of the local steams. Operating expenses several million dollars Intermediate Mitigation Developed by examining the most significant impacts of sewering as they affect areas of high cultural, recreational, or biological importance. Ponds The plan for the ponds would be to stabilize the water surfaces of these water bodies because of a lowered water table, pool elevations of some ponds will be below their spillways. Reduced streamflow will result in less flushing of nutrients and algae, which will tend to accelerate eutrophication. Controlling the causes of eutrophication would be costly and impractical at the time Options for pond mitigation Dredging Herbicides, algicides, aeration Clay liners Shallow well Aquascreen Treated Wastewater
Impacts to shellfish in Nassau County are not expected to be significant.

Intermediate Mitigation Approach Developed by examining the most significant impacts of sewering as they affect areas of high cultural, recreational, or biological importance. Wetlands Impact of sewering will be to create a drier environment in which drier vegetation will be gradually replaced by upland-type plant communities 1-2 foot dams at selected stream locations, irrigation with stormwater runoff Marine Waters Projections of changed salinity were made in this study Impacts to shellfish in Nassau County are not expected to be significant Master Water Plan Would completely mitigate the impacts from sewering in the western portion of the county, while at the same time have a slightly adverse environmental impact in eastern Nassau. The MWP has not yet been adopted by the county. Proposed plan would redistribute up to 28 MGD of groundwater from well fields to be installed at Muttontown Preserve and Manet to Hills Park in northeastern Nassau areas in western Nassau to eliminate local overpumpage of the groundwater there and to supply water where the aquifer may be contaminated. The redistribution plan would result in a raise in water table elevations in western Nassau and lower elevations in the eastern portion of the county. Construction cost of $59 million, annual operating costs were estimated to be about $2.2 million.
Conducted By: Long Island Regional Planning Board Focus: The purpose was to identify cause-effect relationships and
to provide the best available guidance for use by public officials, developers and Long Island residents concerned with the protection of ground and surface waters.

1984 NonPoint Source Management Handbook: Recommendations Land use recommendations NYS should enact legislation authorizing municipalities individually or in concert, to establish Special Groundwater and Special Surface Water Protection Districts. County Health Departments should establish a listing of non-polluting industries to aid the municipalities in determining which may be acceptable in non-sewered Revise comprehensive plans to incorporate the objectives and carry out recommendations contained in the 1978 208 Wastewater Management Plan Limit new development New industries with wet discharges be located in sewered areas. Concentrate high density land uses in existing high density or commercial industrial areas Decrease permitted residential ranging Limit the removal of natural vegetation and the creation of lawn areas. Establishment of Special Groundwater Protection Areas Comprise a relatively undeveloped portion of a deep recharge area, or of a shallow recharge area underlain by saltwater, that requires comprehensive management to maintain existing water quality and quantity. Areas that are candidates have one or more of the following characteristics Undeveloped groundwater recharge area where groundwater withdrawal is occurring or is expected to occur. An area underlain by a high quality aquifer that may be contaminated if the land is developed according to existing zoning. An area where the presence of extensive groundwater contamination limits or can be expected to limit the amount of potable water that can be made available at a reasonable cost. Stormwater Run-off Limit impermeable paving on publicly owned lands Acquire and maintain surrounding watershed areas that have dried up due to sewering Require a stormwater management plan for any plan that A plat is to be recorded Land is to be subdivided An existing drainage system may require alteration New development is proposed for more than one residential unit on a given plat New development for any use other than a single family residence is proposed The rate or volume of runoff will be significantly increased On-site water drains to a pond, stream or other surface water body or to a wetland Require an erosion control plan whenever a stormwater management plan is required Withhold the certificate of occupancy until the erosion and stormwater measures are installed. Use cluster development Use proper site design Minimize grade changes and site clearing Retain native vegetation Avoid the use of paved surfaces Incorporate the following general stormwater controls checklist into the site On-site Septic NYS legislative action is recommended to amend Article 17, Title 7 of the NYS Environmental Conservation Law to require sewage treatment for sewage discharges greater than 1,000 gallons per day in the aquifer recharge areas Nassau County to adopt a provision similar to Article 6 of Suffolk County Health Code Towns not allow the conversion of single family homes to two family units in unsewered deep recharge or critical shallow recharge areas Highway Deicing Inventory and classify existing salt piles Relocate Salt Piles Away from fresh surface water, flood-prone areas, aquifer recharge areas, steep slopes Upgrade existing salt pile sites in Important Aquifer Recharge Areas Consider joint use of existing storage facilities Consider the use of standardized salt storage facilities Design salt structures to provide needed capacity, maximum protection of salt, easy access, and to facilitate environmentally acceptable operations Raise floor levels above 100 year flood level Plan for inevitable accidents Cover the pile with a tarp Require brine control for all salt storage facilities

Groundwater quantity management programs Augment the current Long Island Well permit program to more fully achieve regional groundwater quantity management Prepare a regional water quantity strategy for Long Island under the 1984 State Water resources Strategy legislation Develop preliminary design plans, environmental assessments, surveys and applications to seek and obtain project approval for development of an intracounty transmission system. NYSDEC and NYSDOH should seek legislative appropriations to evaluate the extent of potential application of water conservation measures on Long Island, the potential impact on water use under typical Long Island urban/suburban conditions, and the costs of alternative conservation measures. Nassau County should continue its demonstration project on advanced wastewater treatment/aquifer recharge. Response and Remediation Programs DEC should prepare a guidance document addressing petroleum and hazardous material spills and cleanup Develop a training program for spill response personnel Recover the cost of cleanup activities from the responsible part (spiller) Perform trackdown on sources of contamination to groundwater Develop a document which identifies, described, and maps all known contaminated segments, update every three years Identify areas of private well contamination needing public water supply Evaluate the extent and impact of leaky storm and sanitary sewers on the groundwater resource.

1989 Long Island Region Water Resource Management Strategy Quantity: Findings No water supplies in the region rely on surface water supplies (except fisher island No pumping of Lloyd aquifer Nassau County is at or above estimates of permissible sustained yield of the groundwater resource Recommendations NYSDEC should complete the development of specific criteria for quantity aspects of the region’s water resources. Parameters should be developed for acceptable thickness of freshwater lenses. Develop specific plans for areas where future water quantity is expected to be an issue. DEC conduct further investigations of the Lloyd Aquifer. Ways to supplement water to Nassau County Conservation Intra-county water transfers induced groundwater underflow from Suffolk County Piped transfers, conjunctive use or direct purchase of NYC supplies Artificial recharge of treated wastewater, desalination Quality Findings Many instances of groundwater contamination Excessive pumpage could accelerate the movement of contaminated water to a well Recommendations Continue to develop specific contaminant limits Long Island Groundwater Management Program should be reviewed and updated on a three year cycle.

Suffolk County should continue to provide support for the Cornell Extension Service outreach programs that assist farmers in reducing excessive or inappropriate use of agricultural chemicals or irrigation. Encourage shift from potatoes to crops that require lesser amount of agricultural chemicals and water. Avoiding the Establishment of New Sources of Contamination NYS school districts should refrain from disposing of open lands on its university and college campuses, mental hospitals, other state owned sites. Municipalities should utilize their police power authority to enact land use controls that preclude or limit new sources of contamination within SGPA Develop more stringent groundwater effluent standards for SPDES discharges within SGPAs DEC should utilize its authority to restrict or to can the application of pesticides within an SGPA Construction and Demolition landfills located within an SGPA be double lined Nassau and Suffolk should establish contingency fund for emergency cleanups

2003 Long Island Source Water Assessment Summary Report Results and Conclusions Three dimensional groundwater models were used to estimate the land surface are contributing recharge to each well under the long-term average conditions. Estimate the minimum time of travel. Potential for existing land uses and regulated activities located within each well’s source water area to introduce contaminants to the aquifer. Susceptibility of each public supply well to contamination of microbials, nitrates, pesticides, and VOCs High susceptibility ratings does not imply the water at that well will eventually become contaminated Ratings provide priorities and targets for water quality protection and management programs

Presentation Notes
SGPA Recommendations Municipalities and the County health departments can use their respective zoning and sanitary code authority to limit or prohibit the establishment or expansion of land uses and activities involving the storage, use or disposal of potential contaminants. Towns and villages can utilize zoning and other land use control powers to establish and maintain potential nitrate and household hazardous product contamination. Health Departments through sanitary code regulations of on-site systems based on lot size can support the effort to achieve environmentally acceptable residential densities. Bi-county effort to purchase and preserve open space and insure the quality of the underlying groundwater. Support household hazardous waste disposal programs and dissemination of information Retention of undisturbed woodlands, wetlands, natural buffer areas and rights of way can prevent the long term loss of clean recharge forgoing for a one-time monetary gain. Administrative Recommendations Each County has been relatively independent of one another in their respective management of groundwater, including supply, wastewater and sewage control and inter-county cooperation and coordination. Both counties would benefit if joint action were to occur, including shared use of seage treatment facilities, and shared access to potable water.
