Groundwater treatment with the use of zero-valent iron in the PRB Technology
The industrial dumping sites located in the southern provinces of Poland pollute the groundwater with metals. In the article, the possibility of groundwater (polluted by metals) treatment with the use of PRB Technology has been presented. In this technology, the contaminants are removed from the aquifer by the flow of the groundwater through a PRB filled with a special reactive material. The ...

Model R OXIGEST - Petroleum Refinery - Case Study
A large, Midwestern oil refinery installed two identical, 110’ diameter S&L Model R OXIGEST® treatment systems to solve a groundwater treatment problem on-site. Each plant incorporates aeration, clarification, and effluent holding, treating peak flows of 7.2 MGD combined; 4.3 MGD in each plant. The plant operates with a Food-to-Mass (F/M) typical of extended aeration conditions ...

In Search of Ideal Groundwater Treatment
As surface water supplies become increasingly polluted and difficult to treat, the use of groundwater continues to increase. Every day, more than 77 billion gal of water are withdrawn from aquifers for a variety of uses including human consumption. Worldwide, groundwater makes up 95% of available freshwater, and nearly half of the U.S. population receives all or part of its drinking water from ...

4 Benefits of Electrocoagulation for Groundwater Treatment
Even though groundwater sources are somewhat safer from pollution and contamination due to their underground location, they are still susceptible. A factory may not be able to discharge wastes directly into a groundwater source like they can a surface water stream or river. However, there are many other ways that waste could potentially contaminate a groundwater source. Because soil is ...

TerraTherm to Remediate Soils at the Beede Waste Oil Superfund Site - Case Study
The Beede Site is the former location of a state-licensed and regulated waste oil recycling and disposal facility. The nearly 41-acre Site is located in a residential area of Plaistow, New Hampshire (NH). Operations at the Site began in the 1920s, and continued until the state of NH ordered its closure in 1994. From the 1920s to 1994, thousands of NH residents and businesses were customers of the ...

Horizontal Well Rehabilitation at NASA Facility
A horizontal groundwater extraction well at an active NASA facility in Louisiana was impacted by mineral scaling and bio-fouling affecting operations of the groundwater pump and the treatment system. A flow reduction of over 50% was observed. Directional Technologies, Inc. performed a series of horizontal well rehabilitation activities, that increases flow by 58%, which including mechanical and ...

Worlds First Magnetic Ion Exchange Water Treatment Plant to be Installed in Western Australia
Since the mid-1980s, the Water Corporation of Western Australia (WCWA) has been investigating technologies to prevent an intermittent ‘swampy’ odor occurring in the city of Perth’s treated ground-waters (O’Leary and Herbert, 1998). Groundwater contributes around 50% of the water supply for Perth, which has a population of approximately 1.3 million. The Wanneroo Groundwater Treatment Plant (GWTP) ...

Refinery remediation: fuel recovery and recycling
Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

Transport of enterococci and F+ coliphage through the saturated zone of the beach aquifer
Coastal groundwater has been implicated as a source of microbial pollution to recreational beaches. However, there is little work investigating the transport of fecal microbes through beach aquifers where waters of variable salinity are present. In this study, the potential for fecal indicator organisms enterococci (ENT) and F+ coliphage to be transported through marine beach aquifers was ...
