Sustainable electro-bioremediation of multi-contaminated groundwater
Groundwater resources are threatened by a wide range of natural and anthropogenic pollutants, which restrict their potential for human consumption. The bioelectrochemical systems (BES) have received considerable attention as novel technologies for the remediation of contaminated groundwater due to …

Removal of nitrate from contaminated groundwater by floating alginate beads
… dissolved nitrate in waterways, particularly in groundwater, is a common and serious environmental problem that remains largely unsolved despite intensive research efforts. Major risks posed by dissolved nitrate in water are two-fold: (a) it is hazardous to human health, and (b) it contributes to …

Denitrification as a means of addressing nitrate-contaminated groundwater on Cape Cod, Massachusetts
… face a problem of nitrate contamination of their groundwater (their primary source of drinking water) and their coastal and aquatic environments. Groundwater is the only source of drinking water on Cape Cod and the aquifer is defined as a "sole source aquifer" by the Safe Drinking Water Act. While …

Heterocyclic compounds in tar oil contaminated groundwater : occurence, fate, and indications for natural attenuation
… assess the relevance of NSO-heterocycles in the groundwater of three tar oil contaminated sites and furthermore to search for indications for the presence of natural attenuation processes including the group of NSO-heterocycles. Therefore, as a first step, analytical methods were developed. In …

The isotope geochemistry of uranium: Igneous petrology, ore deposits, and groundwater contamination
… ore genesis, and the remediation of a uranium-contaminated groundwater system. In the latter two cases, 238U/235U is used as a tracer of uranium reduction. 238U preferentially enters the reduced (solid) U phase, thus analysis of U ores can reveal information on the development of an ore body …

A column experiment for groundwater remediation post-mine closure at the Wolverine Mine, Yukon
… semi-passive treatment system for remediation of contaminated groundwater with elevated dissolved metal concentrations, including selenium and sulphate, at the Wolverine Mine, Yukon. Laboratory up-flow columns were used to treat simulated mine impacted waters. Five columns were filled with varying …

Geochemical interpretation on groundwater flow in the Southern Great Basin
… and integrated water flow can help identify groundwater sources and improve predictions of contaminant fate and transport in groundwater systems. Understanding groundwater flow paths in and around the Nevada Test Site (NTS) is important due to the possible migration of contaminated …

The removal of perchlorate from waters using ion-exchange resins
… using both synthetic solutions and perchlorate-contaminated water from the Las Vegas Valley. For synthetic solutions, styrenic strong base resins showed high perchlorate removal efficiency but regeneration efficiency was low. Acrylic strong-base resins showed satisfactory perchlorate removal, …

RECOVERY-RD: The Development of a Biotransformation Model for Sediment Systems Contaminated with PCBs
… with Polychlorinated Biphenyl (PCB) compounds in contaminated sediments for a variety of aquatic environments, including rivers and marine systems. RECOVERY-RD is intended as a screening tool for evaluating the impact of engineered sediment caps on contaminant remediation. The two key components …
