INTRODUCTION • Concerns over the viability of the fractured bedrock aquifer that provides about 1/3 of Rockland County’s water supply prompted a 5-year study by the U.S. Geological Survey (USGS) to (1) define the hydrogeologic framework of the aquifer, (2) assess conditions within it, and (3) identify other potential sources of water for the County. The study was done in cooperation with Rockland County and the New York State Department of Environmental Conservation. • Population growth in Rockland County to nearly 300,000 people has been paralleled by significant hydrologic changes over the past 50 years –water demand and impervious surface area have increased, and sanitary sewers now serve most areas and discharge...

Responsibility for water is divided between the federal, provincial and territorial governments in Canada, and each government has pursued its own path. The resulting water policy landscape is highly fragmented. Issues exist that may warrant regional or national policy coordination. Examples relate to climate change adaptation, water exports and ecosystem protection, to name a few. Previous efforts to coordinate water policy in Canada have largely resulted in failure. This appears to leave Canada in a trailing position relative to numerous countries around the world that have pursued a more coordinated approach to water policy. Paradoxically, however, the failure of previous water policy coordination efforts creates...

Background A major focus of the NAWQA Program in its second decade (2002-2013) is on regional- and national-scale assessments of groundwater-quality status and trends in principal aquifers. The U.S. Geological Survey Office of Groundwater has identified 62 principal aquifers in the U.S. ( U.S. Geological Survey, 2003 ). About 1/3 of the Nation's principal aquifers are the focus of water-quality assessments at the regional scale by NAWQA. The NAWQA framework for principal aquifer assessments considers the physical setting of the aquifer, in addition to its susceptibility and vulnerability to contamination.

The data set includes delineation of sampling strata for the six study reaches of the UMRR Program’s LTRM element. Separate strata coverages exist for each of the three monitoring components (fish, vegetation, and water quality) to meet the differing sampling needs among components. Generally, the sampling strata consist of main channel, side channel, backwater, and impounded areas. The fish component further delineates a “shoreline” portion of the strata to be used for sampling gears deployed only along the shoreline. The data are raster in origin, with the center of each pixel representing the sampling location. Cell size is typically 50 meters, although several water quality strata are at 200 meter cell size.

The Matanuska-Susitna Valley is in the northeastern part of the Cook Inlet Basin, Alaska, an area experiencing rapid population growth and development proximal to many lakes. Here water commonly flows between lakes and ground water, indicating interrelation between water quantity and quality. Thus concerns exist that poorer quality ground water may degrade local lake ecosystems. This concern has led to water-quality sampling in cooperation with the Alaska Department of Environmental Conservation and the Matanuska-Susitna Borough. A map showing the estimated altitude of the water table illustrates potential ground- water flow directions and areas where ground- and surface-water exchanges and interactions might occur....

Following the 2018 eruption of Kīlauea Volcano (Neal et al, 2019) and the subsequent collapse of the Halema’uma’u crater, groundwater gradually seeped into the newly-deepened crater (Nadeau and others, 2020). Water was first observed in the crater on 7/26/2019, and the water level increased over time until 12/20/2020, when the crater again filled with lava, vaporizing the lake. In the intervening time, three sets of water samples were collected by unoccupied aircraft systems (UAS) and analyzed for water chemistry, water isotopes, and sulfur isotopes. The solids filtered from the collected water samples were analyzed by XRD and SEM, as well as digested and analyzed for their chemical composition. Additionally, two...

Problem Previous hydrologic studies have indicated that there may be sufficient water resources underlying Richmond, New York, and Bronx Counties for use as a supplemental water supply by the New York City Department of Environmental Protection (NYCDEP) in times of a drought or other water shortage. Unfortunately, comprehensive data on the quantity and quality of the Counties' water resources are not available to make an accurate assessment. In order to evaluate the availability and suitability of these resources, representative and timely data on the ground-water and surface-water resources of these three Counties are needed. Objectives The primary objective is to develop, operate, and maintain long-term monitoring...

The Yukon River Basin, which encompasses 330,000 square miles in northwestern Canada and central Alaska (Fig. 1), is one of the largest and most diverse ecosystems in North America. The Yukon River is also fundamental to the ecosystems of the eastern Bering Sea and Chukchi Sea, providing most of the freshwater runoff, sediments, and dissolved solutes. Despite its remoteness and perceived invulnerability, the Yukon River Basin is changing. For example, records of air temperature during 1961- 1990 indicate a warming trend of about 0.75 °C per decade at latitudes where the Yukon River is located. Increases in temperature will have wide-ranging effects on permafrost distribution, glacial runoff and the movement of carbon...

The history of water resources management in the Yukon has been characterized by conflict. This problem is due to the failure to address the interrelationships between water and land resources. Although many parts of the Yukon remain largely undisturbed wilderness areas, development pressures place increasing demands on Territorial water resources. To ensure these stresses do not degrade Yukon waters to the extent common in many Canadian regions, a reevaluation of the legal and administrative arrangements for water management in the Yukon is required. A majority of the legislation pertaining to water management in the Yukon was introduced in the 1970s and is unable to address many contemporary issues. The recent...

Water-management alternatives being considered for New York City involve aquifer storage and recovery, or ASR. An ASR system may store surplus water in an aquifer, then later recover this water in times of short supply. The success of an ASR system depends on the quantity and quality of water that can be withdrawn during recovery phases, which are influenced by hydrogeologic, microbiological, and geochemical factors. Mixing surface waters with ambient ground waters within a deep confined aquifer may cause freshwater/saltwater interface movement, clay swelling, mineral dissolution, new patterns of bacterial growth, and other hydrogeologic consequences. In 2005, data were collected at Tottenville, Staten Island,...
