“…Because the factors were distance-weighted, sources of contamination near sampling sites were distinguished from those further upstream (Stackelberg, 1997). For example, if the applied decay factor is high (-1), sources near a sampling site are most important and distant sources contribute little to contamination at a sampling site, whereas low decay factors (0) represent sources in the entire basin above a given sampling site, indicating that distant and nearby sources may be equally important contributors of a contaminant (O'Brien, 1997;Stackelberg, 1997). Development and application of this spatial model is discussed further in White et al (1992) and Smith et al (1993).…”

“…This paper addresses the first of these evaluations for the Long Island-New Jersey study unit. Two complementary studies were also conducted in which the presence and distribution of trace elements (O'Brien, 1997) and chlorinated organic compounds (Stackelberg, 1997) in bed sediments were evaluated.…”

“…The area occupied by each province increases to the southeast. The Valley and Ridge province occupies the smallest area in New Jersey and is characterized by a series of parallel ridges and valleys trending northeast-southwest(O'Brien, 1997). The steep, mountainous topography of this region has deterred the intensive urbanization seen in most other regions of New Jersey.…”

The level of macroinvertebrate community impairment was statistically related to selected basin and water-quality characteristics in New Jersey streams. More than 700 ambient biomonitoring stations were chosen to evaluate potential and known anthropogenic effects. Macroinvertebrate communities were assessed with a modified rapid-bioassessment approach using three impairment ratings (nonimpaired, moderately impaired, and severely impaired). Maximum-likelihood multiple logistic-regression analysis was used to develop equations defining the probability of community impairment above predetermined impairment levels. Seven of the original 140 explanatory variables were highly related to the level of community impairment. Explanatory variables found to be most useful for predicting severe macroinvertebrate community impairment were the amount of urban land and total flow of municipal effluent. Area underlain by the Reading Prong physiographic region and amount of forested land were inversely related to severe impairment. Nonparametric analysis of variance on rank-transformed bioassessment scores was used to evaluate differences in level of impairment among physiographic regions and major drainage areas simultaneously. Rejection of the null hypothesis indicated that the levels of impairment among all six physiographic regions and five major drainage areas were not equal. Physiographic regions located in the less urbanized northwest portion of New Jersey were not significantly different from each other and had the lowest occurrence of severely impaired macroinvertebrate communities. Physiographic regions containing urban centers had a higher probability of exhibiting a severely impaired macroinvertebrate community. Analysis of major drainage areas indicates that levels of impairment in the Atlantic Coastal Rivers drainage area differed significantly from those in the Lower Delaware River drainage area.

“…Emissions from automobile exhaust (Ondov and others, 1982) and combustion of fossil fuels from smelting, refining, and metal processing emit trace elements to the atmosphere, including cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), antimony (Sb), and zinc (Zn). These elements fall to earth through dry or wet deposition and may eventually be mobilized through storm runoff and enter streams (Brigham and others, 1997;Harte and others, 1991;O'Brien, 1997;Winter, 1998). Leaching from abandoned mine tailings or other workings is a common source of trace elements to the environment.…”

The U.S. Geological Survey (USGS) is committed to serve the Nation with accurate and timely scientific information that helps enhance and protect the overall quality of life, and facilitates effective management of water, biological, energy, and mineral resources (http://www.usgs.gov/). Information on the quality of the Nation's water resources is of critical interest to the USGS because it is so integrally linked to the long-term availability of water that is clean and safe for drinking and recreation and that is suitable for industry, irrigation, and habitat for fish and wildlife. Escalating population growth and increasing demands for the multiple water uses make water availability, now measured in terms of quantity and quality, even more critical to the long-term sustainability of our communities and ecosystems. The USGS implemented the National Water-Quality Assessment (NAWQA) program to support national, regional, and local information needs and decisions related to water-quality management and policy (http://water.usgs.gov/nawqa). Shaped by and coordinated with ongoing efforts of other Federal, State, and local agencies, the NAWQA program is designed to answer: What is the condition of our Nation's streams and ground water? How are the conditions changing over time? How do natural features and human activities affect the quality of streams and ground water, and where are those effects most pronounced? By combining information on water chemistry, physical characteristics, stream habitat, and aquatic life, the NAWQA program aims to provide sciencebased insights for current and emerging water issues and priorities. NAWQA results can contribute to informed decisions that result in practical and effective water-resource management and strategies that protect and restore water quality. Since 1991, the NAWQA program has implemented interdisciplinary assessments in more than 50 of the Nation's most important river basins and aquifers, referred to as Study Units (http://water.usgs.gov/nawqa/ nawqamap.html). Collectively, these Study Units account for more than 60 percent of the overall water use and population served by public water supply, and are representative of the Nation's major hydrologic landscapes, priority ecological resources, and agricultural, urban, and natural sources of contamination. Each assessment is guided by a nationally consistent study design and methods of sampling and analysis. The assessments thereby build local knowledge about water-quality issues and trends in a particular stream or aquifer while providing an understanding of how and why water quality varies regionally and nationally. The consistent, multi-scale approach helps to determine if certain types of water-quality issues are isolated or pervasive, and allows direct comparisons of how human activities and natural processes affect water quality and ecological health in the Nation's diverse geographic and environmental settings. Comprehensive assessments on pesticides, nutrients, volatile organic compounds, trace metals, and aquatic...

Anthropogenic-Occurring because of, or influenced by, human activity. Aquatic Invertebrates-Insects, worms, crayfish, snails, clams, and other organisms without a backbone that inhabit lakes, streams, rivers, or oceans. Base flow-Sustained, low flow in a stream; groundwater discharge is the source of base flow in most streams. Benchmark site-See reference site. Benthic-Organisms living on or burrowing into aquatic substrates. Drainage basin-The portion of the surface of the Earth that contributes water to a stream through overland runoff, including tributaries and impoundments. Embeddedness-The degree to which gravel-sized and larger substrate particles are surrounded or enclosed by finer sized particles. Ichthyofauna-Refers to fish. Impervious surfaces-Hard, non-porous surfaces in a watershed such as asphalt, concrete, buildings, and other compacted or impermeable surfaces that prevent precipitation from infiltrating into the ground, thus increasing surface runoff. Index of Biotic Integrity (IBI)-An aggregated number, or index, based on several attributes or metrics of a fish community that provides an assessment of the health of aquatic systems. Integrator site-Stream-sampling site located at an outlet of a drainage basin that contains multiple environmental settings. Most integrator sites are on major streams with relatively large drainage areas. Interstitial space-The space between substrate particles (substrate porosity) that provides a refuge for aquatic organisms. Intolerant organisms-Organisms that are not adaptable to human alterations to the environment and commonly decline in number where human alterations occur. See also tolerant species.

Reference site-A sampling site selected for its relatively undisturbed conditions. Relative abundance-The number of organisms of a particular kind present in a sample relative to the total number of organisms in the sample. Retrospective analysis-The review and analysis of available water-quality and ecological data to provide a historical perspective of water quality and biological integrity, to assess strengths and weaknesses of available information, and to evaluate implications for water-quality management and study design. Richest targeted habitat (RTH)-A targeted habitat (usually a riffle or woody snag where the taxonomically richest algal or invertebrate community theoretically is located) identified in a reach from which discrete samples of algae or invertebrates are collected and later combined to form a composite sample. The composited sample is referred to as an "RTH sample." Riparian buffer-A vegetated protective area adjacent to rivers and streams with a high density, diversity, and productivity of p...
