Problem – Currently, swim advisories or closings are issued by beach managers based on standards for concentrations of bacterial indicators such as Escherichia coli (E. coli). Standard culture methods for these bacteria take at least 18-24 hours before results are available. At most Great Lakes beaches, the beach is posted with an advisory or closing or is determined to be acceptable for swimming on the basis of the previous day’s E. coli concentration. Sanitary conditions may change overnight and even throughout the day (Boehm and others, 2002) making decisions made from previous days information incorrect. Because of this time-lag issue, water-resource managers are seeking solutions that provide near real-time...

Problem The shallow groundwater of Nassau and Suffolk Counties is prone to contamination from current land-use, including agricultural, residential, and recreational. The aquifer system of Long Island is highly susceptible to human-derived contamination, in particular, because the soils and underlying sediments are generally composed of sandy, permeable materials that allow contaminants to move readily from the land surface into the groundwater below. Of increasing concern are the human-derived contaminants stemming from past and present uses of pesticides. In addition to the threat of direct runoff to adjacent waterbodies, pesticide transport through the shallow aquifer from inland sources may discharge to the...

Problem - In August 2000, eleven sites were sampled from 9 streams within the Croton watershed for pharmaceuticals and other organic compounds associated with wastewater as part of a national study of these compounds in streams receiving wastewater discharges. Results from the national study indicated that streams in the Croton Reservoir downstream of sewage treatment plants had concentrations of target compounds. Detected compounds included pharmaceuticals, detergent degradates, insecticides, caffeine, and other organic compounds (Kolpin and others, 2002). The results indicate that these compounds are commonly present in streams below wastewater treatment plants (WWTPs). Many of these compounds have not been...

Introduction Mosquitoes are the principle vector of the West Nile Virus (WNV) which causes infections in humans and animals and has emerged as a public health threat throughout Long Island, NY. The WNV was first detected among birds and mosquitoes by the Suffolk County Department of Health Services (SCDHS) in 2000. In response to the public health concern, the USGS in cooperation with the SCDHS, began a 3-year study in 2002 to sample surface waters in selected wetlands for insecticides which were sprayed seasonally from a truck or helicopter as part of the county's vector-control program. These insecticides include Altosid (methoprene) and Scourge [1:3 ratio of resmethrin and piperonyl butoxide (PBO)]. Methoprene...

Problem The groundwater supply of Nassau and Suffolk Counties is prone to contamination from past and current land uses, including practices related to agriculture, industry, and residential development, because the soils and underlying sediments are generally composed of sandy, permeable materials that allow contaminants to move readily from the land surface into the groundwater below. Of increasing concern are the human-derived contaminants stemming from on-site disposal of residential wastewater and industrial processes. The centralized distribution of water through purveyors to most residents provides them with a reliable source of potable water that is consistently monitored at the wellhead. However, increased...

Background The Long Island-New Jersey (LINJ) coastal drainages NAWQA study is one of the 1994 set and is coordinated from our West Trenton, NJ office. Tasks for the first two years, 1994-95, included staffing, developing a liaison process, analyzing existing data, and designing a data collection program that started in 1996. These planning activities lead to the study design for 3 years of intensive data collection in 1996-98. The intensive efforts includes multi-scale study approaches to collect samples of water, suspended and bed sediment, biologic tissues, and aquatic communities. The LINJ NAWQA study is scheduled to enter a low-intensity phase of monitoring and report writing in 1999 and return to another...

Background The Shinnecock Nation is located on the south fork of eastern Long Island adjacent to the town of Southampton to the east, and the hamlet of Shinnecock Hills to the west, in Suffolk County, NY. Shinnecock Nation tribal lands encompass approximately 1.2 square miles and are bounded to the east and west by tidal creeks, and to the south by Shinnecock Bay. The Shinnecock Nation has a population of 662 residents who live in 256 housing units (U.S. Census, 2016). The Shinnecock Nation became the 565th federally recognized Tribe by the United States government in October 2010. (Shinnecock Nation, 2014). Shinnecock Nation tribal lands are situated in a coastal environment where bay and wetland health are...

Problem Samples were collected from 10 Key Point sites in the New York City Reservoir system as part of the cooperative USGS-New York State Department of Environmental Conservation (NYSDEC) statewide pesticide monitoring project ( Phillips and others, 2000). Ten pesticides were detected in the key-point samples collected between January 1999 and September 2000 - the herbicides atrazine, metolachlor, simazine and prometon, the herbicide degradates deethylatrazine, hydroxyatrazine, alachlor ethanesulfonic acid (ESA), metolachlor ESA, and metolachlor oxanilic acid (OA), and the insecticide diazinon. Concentrations for most of these detections were generally low (between 0.001 and 0.05 ug/L), with the exception of...
