Marrack, L., 0000. Incorporating groundwater levels into sea level detection models for Hawaiian anchialine pool ecosystems. Journal of Coastal Research, 00(0), 000–000. Coconut Creek (Florida), ISSN 0749-0208. As sea levels rise, the distribution and community structure of coastal ecosystems are expected to change. In many coastal aquifers, fresher groundwater floats on top of denser saltwater...

introduction groundwater resources in arid-semiarid zones universally suffer from problems of over-abstraction and declining water tables. in addition to the issues related to quantity, degradation of groundwater quality now assumes major importance in the arid and semiarid regions. in such areas, natural factors such as the low precipitation, combined with high evapotranspiration, result in hi...

Water has an important role in creating pollution problems in the mining regimes influencing the surrounding surface environment. The purpose of this study is to make an assessment of groundwater quality in an underground mine site in Portugal with a view of determining the pollution potential of groundwater. In the corresponding surface area of this underground mine, intersec...

An in situ co-metabolic air sparging (CAS) study was carried out at McClellan Air Force Base (MAFB), Sacramento, CA, USA, in a trichloroethene- (TCE) and cis-dichloroethene (cis-DCE)-contaminated aquifer where one test zone received 2% propane in air and the other served as a control and received only air. As part of that study, bacterial population shifts were evaluated by length heterogeneity...

In the Pingtung Plain of southern Taiwan, elevated levels of NO₃--N in groundwater have been reported. Therefore, efforts for assessing groundwater vulnerability are required as part of the critical steps to prevent and control groundwater pollution. This study makes a groundwater vulnerability assessment for the Pingtung Plain using an improved overlay and index-based DRASTIC model. The improv...

We measured denitrification, immobilization, and respiration in microcosms that simulated groundwater conditions in a riparian forest in Rhode Island. Measured rates were compared with rates of NOj" removal measured in a companion study using a groundwater monitoring well network and 10-mo injection of NOf and a bromide tracer to groundwater in the same riparian forest. Limiting factors for den...

Nitrate concentration in groundwater has frequently been linked to non-point pollution. At the same time the existence of intensive agriculture and extremely intensive livestock activity increases the potential for nitrate pollution in shallow groundwater. Nitrate used in agriculture could cause adverse effects on human and animal health. In order to evaluate the groundwater nitrate pollution, ...

Background and Purpose: Elevated nitrate concentrations in drinking water can cause methemoglobinemia in infants, stomach cancer in adults and nitrate poisoning in animals as well. Modeling of nitrate fate and transport in groundwater to minimize nitrate concentration in groundwater has been studied by numerous researchers. Materials and Methods: In order to determine the pote...

in recent years, dousti dam has been one of the most important mashhad’s sources of drinking water. in this way, 500 million cubic meters of the outflow of the dam enter into the mashhad watershed. with the arrival of this volume of water, the drinking water wells in the city were turned off. on the other hand, the development of some urban infrastructures such as the sewer collecting network d...
