Summary

Background: The New York State Departments of Environmental Conservation (NYS DEC) and Health (NYS DOH) are concerned about groundwater contamination in the carbonate-bedrock aquifers in New York, especially relating to the unintended introduction of volatile organic compounds (VOCs) and liquid manure to these aquifers. These carbonate rocks form extensive aquifers that transmit, and can yield, water from solution-enlarged fractures, bedding planes, and other openings (Olcott, 1995). Groundwater contamination from liquid manure application (fecal coliform bacteria [E. coli] and nitrate) has been on the increase over the past decade as these incidents have been reported to the NYS DEC. Nitrate is highly water-soluble and thus can move [...]

typeShort Project Description
valueNew York’s carbonate-bedrock aquifers are poorly characterized. The objective of this proposal is to determine the extent of the susceptible carbonate bedrock, and where recharge would most-likely enter the aquifer system. Information on locations where aquifer contamination has occurred over or near carbonate bedrock is crucial in understanding the surface water/ground water connections that facilitate focused recharge. Compilation of this initial statewide information will be useful in determining which parts of these carbonate bedrock units in the State need detailed assessment. These detailed assessments will provide information to DEC and other agencies to develop guidelines for agricultural and industrial operations, and assessment of the potential for chemical-spill and chemical-waste problems in these aquifers.

productDescriptionThe information will be summarized in an on-line report describing the methods used to collect and interpret the data outlined above, and provide a GIS dataset showing: 1. Extent of the carbonate bedrock units identified above based on the NYS 1:250,0000-scale bedrock maps. 2. Associated buffer areas for the mapped carbonate bedrock units. 3. Closed-depression features – identified from analysis of the NYS DOT topographic quadrangles. Such features will only be identified for the selected carbonate bedrock units and their buffer areas, and within a 1 to 2 miles extension from the carbonate buffer areas as mapped by this study. These depressions will not be validated as to their hydrogeologic nature. 4. Location of suspected focused-recharge events as identified by County Health Departments and Soil-Water Conservation District personnel, as formally requested by the NYS DEC if sufficient data is obtained from the County Health Departments, and Soil and Water Conservation Districts. The GIS dataset will be prepared for public distribution, and will: (1) include Federal Geographic Data Committee (FGDC) compliant metadata; (2) undergo review by USGS and colleagues, and (3) be available via the New York State GIS Clearinghouse. An illustration of a hypothetical coverage/shapefile output is shown in fig. 4 for reference.
