Distribution and differences in wetland type, vegetative composition, and soil type are caused primarily by geology, topography, and climate. Differences also are the product of the movement of water through or within the wetland, water quality, and the degree of natural or human-induced disturbance. In turn, the wetland soils and vegetation alter water velocities, flow paths, and chemistry. The hydrologic and water-quality functions of wetlands, that is, the roles wetlands play in changing the quantity or quality of water moving through them, are related to the wetland's physical setting.

Wetlands are distributed unevenly throughout the United States because of differences in geology, climate, and source of water fig. They occur in widely diverse settings ranging from coastal margins, where tides and river discharge are the primary sources of water, to high mountain valleys where rain and snowmelt are the primary sources of water.

Marine wetlands those beaches and rocky shores that fringe the open ocean are found in all coastal States. Estuarine wetlands where tidal saltwater and inland freshwater meet and mix are most plentiful in Alaska and along the southeastern Atlantic coast and the gulf coast. Alaska has the largest acreage of estuarine wetlands in the United States, followed by Florida and Louisiana.

Inland nontidal wetlands are found in all States. Some States, such as West Virginia, have few large wetlands, but contain many small wetlands associated with streams.

Other States, such as Nebraska, the Dakotas, and Texas, contain many small isolated wetlands--the lakes of the Nebraska Sandhills, the prairie potholes, and the playa lakes, respectively. Northern States such as Minnesota and Maine contain numerous wetlands with organic soils peatlandssimilar in origin and hydrologic and vegetative characteristics to the classic bog and fen peatlands of northern Europe.

However, peatlands are by no means limited to Northern States--they occur in the Southeastern and Midwestern United States wherever the hydrology and chemical environment are conducive to the accumulation of organic material.

This research, which addresses the historical contamination of groundwater resources in the northern karst region was conducted through integration of spatial hydrogeologic and contaminant concentration data in the La Plata-Arecibo area.

The study used GIS technologies and focused on phthalates and chlorinated volatile organic compounds CVOCs and phthalates due to their ubiquitous presence in the environment as well as their presence in listed and potential superfund sites in Puerto Rico and U.

Results show an extensive historical contamination of the groundwater resources in the northern karst aquifers. The degradation of this important water resource has resulted in a subsequent reduction of the extraction capacity and an increase in the cost of use. This aquifer serves as a significant source of water for domestic, industrial, and agricultural uses DNER, Groundwater in the region also discharges to surface water features, contributing to the ecological integrity of stream, wetlands, costal lagoons, and estuaries.

The north coast karst groundwater system contains two major aquifers Lugo et. The upper aquifer is connected to the surface throughout most of its outcrop area. The lower aquifer is confined toward the coastal zone coast and outcrops to the south of the upper aquifer, where it is recharged. Groundwater in both aquifers flows from recharge areas toward discharge areas near the coast, streams, wetlands, springs, and other surface-water features Renken et.

Extraction wells are used for domestic, industrial, and agricultural purposes, with the largest fraction used for public supply, followed by the industrial and agricultural sectors Molina, Groundwater is mostly extracted from the upper aquifer because it is the most accessible for drilling and pumping, but several industrial wells and a few for public water supply tap the lower aquifer.

Modified from Veve and Taggart, The high productivity of the northern karst aquifers is imparted by well-developed conduit porosity and highly transmissive zones developed by dissolution of soluble rocks, primarily limestone and dolomite, in which groundwater flows Figure 3. As a result, karst aquifers serve as an important route for exposing humans and wildlife to contaminants. Many of these industries rely on the use of hazardous materials, which can enter the karst groundwater from accidental spills and deliberate disposal.

Urban growth brought construction of municipal landfills and clandestine waste disposal sites. Many of the clandestine sites were developed in sinkhole depressions, which serve as a direct route of contaminants into the underlying groundwater formations.

The unintended consequence of the industrial and urban development has therefore been extensive contamination of the groundwater resources in the northern karst aquifer.

The degradation of this important resource has subsequently resulted in a reduction of the extraction capacity and the cost of use. The study focuses on chlorinated volatile organic compounds CVOCs and phthalates because of their ubiquitous presence in the environment as well as their presence in listed and potential superfund sites in Puerto Rico and U.

Many phthalates are contained in commonly used products, including plastics, food packaging, home furnishings, paints, clothing, medical devices, and cosmetic products NIH, In landfills, phthalates-containing materials can degrade and serve as a potential source of phthalate contamination for groundwater. Some phthalates are considered endocrine disruptors, and have recently been associated with decreased gestation length Latinireproductive and neurological damage, and the rise of preterm birth CERHR, Exposure to TCE has been related to several adverse health effects, including cardiac, neurological, hepatic, renal, dermal, immunological, and reproductive effects, increased birth defects, perinatal mortality, cancer, decreased birth weights ATSDR,and risk for spontaneous abortion Lipscomb and FensterKhattakHa and Cho The historical contamination of groundwater resources in the northern karst aquifer of Puerto Rico was assessed and integrated using GIS geographic information systems technologies.

The general approach involved collection, analysis, indexing, and segregation of historical and spatial data. Historical since and spatial data was collected for hydrogeology, known and potential sources of contamination, and concentrations of contaminants in the La Plata-Arecibo study area.

Data characteristics were overlain and analyzed within the context of a number of basemaps using ArcGIS 8. This GIS platform uses intelligent data models for representing geographical features, and provides the necessary tools to create and work with spatially-distributed data. The spatial analyst extension for ArcGIS was used to perform the analysis.

Share sensitive information only on official, secure websites. By: Richard A. This report documents the results of an evaluation of the surface-water quantity, surface-water quality, and rainfall data-collection programs in Hawaii. Fourteen specific issues and related goals were identified for the surface-water quantity program and a geographic information systems GIS data base was developed summarizing information for all surface-water stream gages that have been operated in Hawaii by the U.

Geological Survey. Changes in status, which for some gages includes discontinuing operation, need to be considered at 42 sites where data are currently collected. The current surface-water quantity data base was determined to be adequate to address only two of the 14 specific issues and related goals.

Alternatives were identified to address the areas where future issues and goals could not be adequately addressed. Options include new and expanded data collection, use of regional regression analyses, hydrologic and hydraulic modeling, and analysis and publication of existing data. A total of 47 streams were identified where additional stream-gaging stations are needed. Evaluation of the surface-water quality program was limited to a description of the U.

Geological Survey's historical and existing programs and available analyses of data. Limitations of the program are described which primarily included lack of data regarding suspended sediment, land-use effects, quality of stream discharge to oceans, background water quality and nonpoint sources of contamination.

Evaluation of the rainfall data program indicated that identified future goals could be discussed as either regional, systems related, current needs, forecasting, water quality, or trend analysis related. To address these goals, data from about 2, rain gages, of which are active, are available.

Data were found to only partially meet identified goals. Alternatives discussed to address the limitations include the need for more recording gages, primarily in areas of high rainfall. Another area of concern was the potential that many plantations will close and the effect these closings would have on continued operation of the important long-term gages they operate.

Evaluation of data-collection programs in Hawaii needs to be an ongoing process. Equally important, data being collected need to be summarized and made available through data bases and published reports.
