Available in PDF, EPUB and Kindle. Book excerpt: The Passaic River is located in the New Jersey-New York metropolitan area. This river has been heavily polluted by dioxins, PAHs, PCBs and heavy metals due to agricultural, industrial activities, and urbanization. Contaminated sediments in the Passaic River have received considerable attention because contaminants (metals, PCBs. PAHs, dioxins) in the sediments have potential to release into the aquatic system and air through diffusion and/or volatilization, causing human health hazards. Identification of high concentration areas of these Contaminants in the river-estuarine system is critical to the Passaic River environmental restoration and watershed protection. In this study, we analyzed portion of 10 years (1991-2000) data using Geographic Information Systems (GIS) as a tool to study the distributions of contaminants in the sediments. The results from this study provide important information for developing environmental management strategies for the lower Passaic River system.

Download or read book Urbanization written by Luca N. Wagner and published by Nova Publishers. This book was released on 2008 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanization refers to a process in which an increasing proportion of an entire population lives in cities and the suburbs of cities. Historically, it has been closely connected with industrialization. When more and more inanimate sources of energy were used to enhance human productivity (industrialization), surpluses increased in both agriculture and industry. Larger and larger proportions of a population could live in cities. Economic forces were such that cities became the ideal places to locate factories and their workers. This new book presents recent and significant research from around the globe.

This book was released on 2008 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Passaic River System is located within the New York-New Jersey Harbor Estuary. A wide range of toxic chemicals, including heavy metals, pesticides, polychlorinated dibenzo-p-dioxins and dibenzofurans, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) have been found in both sediments and water of the Passaic River.

Available in PDF, EPUB and Kindle. Book excerpt: Erodibility experiments were performed on sediments obtained over a 15-mile stretch of the Lower Passaic River, NJ, to assess remediation options and prioritize remediation as part of the U.S. Environmental Protection Agency's Superfund remedial investigation. A total of 28 sediment cores were extracted from 14 locations on the Passaic River. Measurements of erodibility were performed with U.S. Army Corps of Engineers Sedflume to determine erosion as a function of depth for different shear stresses. Additionally, bulk density, organic content, and grain-size distribution as a function of depth were determined.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to develop a water quality model to quantify nonpoint-source (NPS) pollution that uses a geographic information system (GIS) to link statistical modeling of nutrient and sediment delivery with the spatial arrangement of the parameters that drive the model. The model predicts annual nutrient and sediment loading and was developed, calibrated, and tested on 12 watersheds within the Lake Ray Roberts drainage basin in north Texas. Three physiographic regions are represented by these watersheds, and model success, as measured by the accuracy of load estimates, was compared within and across these regions.

This book was released on 2019 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regression analyses of major ion concentration, and specific conductance were compared on a decadal basis from field data of the 1960s, 1980s, 1990s, 2000s, and 2010s to find if there is a statistically significant increase in calcium, chloride, and sodium compared to other major groundwater ions in the Middle and Lower Passaic River Basins. Time series graphical analyses, bivariate coefficient relationships, statistical prediction interval evaluations, and multivariate analyses were used to determine the significance of the individual ion concentration trends. Through ArcGIS, bedrock geochemistry was examined in correlation with well locations, ion concentrations, and road placements. GIS was used to create groundwater flow maps using previously collected hydraulic head measurements. Time series analyses for the Middle Passaic River Basin indicated that sodium and chloride levels are increasing at different rates throughout the study period. Bivariate plots showed no significant correlation between chloride and sodium nor between chloride and total dissolved solids. Piper diagrams indicate that the groundwater species in this region showed little to no change throughout time. These observations indicate that sodium and chloride show only slight to moderate increases from the 1960s to 2010s in the Middle Passaic River Basin groundwater. The combination of low deicing application, low-porosity basalt, gneiss, and granite bedrock, and the presence of large water reservoirs were considered the responsible variables for the low levels of observable contamination in the Middle Passaic River Basin. Comparatively, ion concentrations for sodium, chloride, as well as calcium (a component of the less common deicing material liquid calcium chloride) increased at substantially greater rates in the Lower Passaic River Basin. Overall, calcium, sodium, chloride, and total dissolved solids increased at significant rates. Sodium against chloride and calcium against chloride bivariate analyses showed strong correlations. This suggests that there is an observable relationship between the ions individually produced via NaCl and CaCl2. Additionally, calcium and sodium show no correlation with one another, suggesting no intermolecular relationship between the two deicing agents. Through multivariate analyses, a shift in groundwater ionic composition from freshwater to salt water was observed in the Lower Passaic River Basin within the study timeframe. These observations indicate that deicing application in the Lower Passaic River Basin has contaminated the underlying groundwater. The high urbanization, road density, and porous bedrock are considered the responsible variables for this outcome.
