Full-scale application of nZVI: remediation of deep contamination plume close to source of drinking water

Treatment of an old disposal site proved to be a challenging task due to its improper placement and insufficient ensuring. The site is located in a very complex geological environment and in imminence of the source of drinking water. Therefore, the soluble in-situ reagents cannot be applied here. NANOFER slurry was chosen by the remediation company AQUATEST for removal of chlorinated hydrocarbons ...

Groundwater remediation pump and treat carberry, Manitoba case study

Executive Summary Two of four underground gasoline tanks were removed from an old service station located in Carberry, Manitoba a number of years after the facility ceased operating. Two tanks were left on site and were used until 1985, when Manitoba Environment was notified that a domestic well in the vicinity of the abandoned site was contaminated with gasoline. The remaining tanks were ...

ORC® Replaces Pump and Treat/SVE Systems and Gains Site Closure

Site Summary Leaking gasoline pipelines caused the groundwater to become contaminated with TPHg at concentrations exceeding 6,000 ug/L. Because the site was located in a busy, high traffic area (in the vicinity of Portland International Airport), the consultants made it a priority to find a less obtrusive and “invisible” remediation system to replace the pump and treat and SVE systems already in ...

Pump-and-Treat Ground-Water Remediation - A Guide for Decision Makers and Practitioners

Pump-and-treat is one of the most widely used ground-water remediation technologies. Conventional pump-and-treat methods involve pumping contaminated water to the surface for treatment. This guide, however, uses the term pump and treat in a broad sense to include any system where withdrawal from or injection into ground water is part of a remediation strategy. Variations and enhancements of ...

GCW as a means of efficiently remediating contaminated groundwater

With the conventional 'Pump & Treat' method, groundwater is normally extracted from one or several wells, cleaned above ground and disposed off to the either groundwater or surface water. Even when extraction and injection wells are combined, predominantly higher perme-able areas are preferentially penetrated and more fine-grained structures are circumflowed. The bulk of contaminants are ...

Lessons Learned from a Dual-Phase Extraction Field Application

ABSTRACT A field-scale Dual-Phase Extraction (DPE) system was installed and operated at the Pinellas Science, Technology, and Research (STAR) Center, formerly the U.S. Department of Energy (DOE) Pinellas Plant, in Largo, Florida, from August 1997 through September 1999. The goal of applying the DPE system was to enhance the pump-and-treat remediation of volatile organic compounds (VOCs) ...

In-Situ Remediation of Heavy Metals Using Sulfur-Based Treatment Technologies

The Metal Problem Highly toxic and highly soluble metals are contained in numerous waste streams including those from power, chemical, electronics facilities, general manufacturing plants, and mining facilities. Lead, chromium, arsenic, zinc, cadmium, copper, and mercury are the most common metal contaminants found on remediation project sites (US EPA, October, 2000). Cyanide is a common ...

Analytical model for uni–directional flow passive soil vapour extraction system

An analytical one–dimensional model has been developed to examine the uni–directional barometric pumping in passive Soil Vapour Extraction (SVE) system. The model is applicable to a special case in which a radial flow field is insignificant. The system considered contains two unsaturated zone layers, an upper contaminated low permeability layer and a lower high permeability layer contains a well ...

In situ Chemical Oxidation: An Innovative Groundwater Remediation Technology

A promising new technology, in situ Chemical Oxidation (ISCO), has the potential to supplant the more widely used pump-and-treat groundwater remediation technology by destroying groundwater contamination in situ (in place). ISCO is the process of oxidizing contaminants in the groundwater and soil by injecting water containing high concentrations of an oxidant to the site of the contamination. ...

‘Smart’ flood alleviation system protects Portsmouth

In late 2014, Southern Water completed a major project to reduce the risk of sewer flooding in parts of Portsmouth and Southsea. Substantial works were undertaken to divert runoff and tidal ingress, and a ‘smart’ hydrometeorological monitoring system was installed to enable prompt diversion of excess water during periods of high rainfall. Sewer level monitoring is undertaken in ...
