Water-Resource and Road-Condition Monitoring of Alternative Treatments for Road Deicing

Introduction The New York State Department of Transportation (NYSDOT) is evaluating alternative treatments for road deicing with the goal of reducing the impact of this activity on the State’s water resources. The NYSDOT has requested support from the U. S. Geological Survey (USGS) in monitoring the effects of these alternative treatments on the water resources. In the past, the USGS has...

Groundwater-Quality of Nassau County, Long Island, New York

Problem Statement There are over 1.3 million residents in Nassau County that rely on groundwater as their sole source of potable drinking water. The mixed land uses (residential, commercial, industrial, agricultural, and recreational) of Nassau County contribute point and non-point sources of aquifer contamination. Nassau County water purveyors currently operate supply wells screened in the...

Development of Long Island Water Quality Integrated Data System (LIQWIDS) - User interface and web services in support of collaboration under the Long Island Nitrogen Action Plan(LINAP)

PROBLEM There are more than 60 organizations and agencies collecting water-quality data on Long Island. The types of database management that are used to store and archive regulatory and non-regulatory data vary from paper forms to spreadsheets to State and Federal databases, and there is minimal communication between these systems. As a result, those interested in analyzing data may be...

Groundwater Sustainability of the Long Island Aquifer System

Groundwater sustainability can be best defined as the development and use of groundwater in a manner that can be maintained for an indefinite time without causing unacceptable environmental or socioeconomic consequences. Informed management of the Long Island aquifer system can help ensure a regionally sustainable groundwater resource. The USGS and New York State Department of Environmental...

305b Groundwater Quality Monitoring in New York

Relatively little data describing the quality of groundwater in New York State exist, yet groundwater is used as a source of drinking water by approximately one quarter of the population of the state. The objective of the 305(b) groundwater quality monitoring project is to quantify and report on ambient groundwater quality from bedrock and glacial-drift aquifers in upstate New York.

Long Island Groundwater Network

U.S. Geological Survey Hydrologic Monitoring on Long Island, New York

Groundwater is the sole source of water supply for more than 3 million people on Long Island, New York. Large-scale groundwater pumpage, installation of sanitary- and storm-sewer systems, and frequent variations in precipitation all have significant effects on regional groundwater levels and aquifer...

Sentinel Monitoring of Groundwater for Contaminants of Emerging Concern to Provide Advanced Warning for Supply Wells on Long Island, New York

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...
