1. A Field and Modeling Study to Determine Pesticide Occurrence in a Public Water Supply in Northern England, UK

Author:
Stuart, Marianne E.; Gooddy, Daren C.; Hughes, Andrew G.; Jackson, Christopher R.
Source:
Ground water monitoring & remediation 2006 v.26 no.4 pp. 128-136
ISSN:

Subject:
public water supply; groundwater contamination; groundwater flow; water treatment; aquifers; watersheds; nonpoint source pollution; hydrologic models; land use; wells; pesticides; sandstone; England
Abstract:
... In the UK, increasing numbers of pesticides are being detected in ground water as monitoring programs are developed and analytic techniques are refined. This study describes the investigation of pesticides at a site on the Triassic Sandstone aquifer of northern England. Drilling and pore water sampling demonstrated the presence of agricultural herbicides in the unsaturated zone of the aquifer clos ...

Subject:
groundwater; environmental monitoring; water quality; water table; poly(vinyl chloride); tubes; equipment design; groundwater contamination; Ontario; Wisconsin
Abstract:
... A modular multilevel system was adapted for high-resolution, depth-discrete monitoring of hydraulic head and ground water quality in rotasonic boreholes or boreholes produced with similar dual-casing drilling methods. The system accommodates up to 15 monitoring intervals within one hole and can be used to monitor overburden and/or bedrock to depths of 100 m (330 feet) or more. It is most effective ...

4. Permeable Reactive Barriers for the Removal of Heavy Metals: Lab-Scale Experiments with Low-Grade Magnesium Oxide

Author:
Navarro, Andrés; Chimenos, Josep M.; Muntaner, David; Fernández, A. Inés
Source:
Ground water monitoring & remediation 2006 v.26 no.4 pp. 142-152
ISSN:
1069-3629
Subject:
heavy metals; magnesium oxide; laboratories; remediation; groundwater contamination; pH; water treatment; permeability; sorption; provenance; Spain
Abstract:
... The attenuation of heavy metals in ground water depends on factors such as solid-solution equilibrium or the solubility product (Ksp) of the solid phase. Metals are pH dependent, and the solubility of heavy metal hydroxides such as lead, cadmium, zinc, and nickel is minimal within pH range 9 to 11. MgO as material in a passive remediation system for removing heavy metals from contaminated ground w ...

5. Source Zone Natural Attenuation at Petroleum Hydrocarbon Spill Sites--II: Application to a Former Oil Field

Author:
Lundegard, Paul D.; Johnson, Paul C.
Source:
Ground water monitoring & remediation 2006 v.26 no.4 pp. 93-106
ISSN:

Subject:
petroleum; oil spills; anaerobic conditions; soil pollution; aerobic conditions; groundwater contamination; hydrocarbons; weathering; infiltration (hydrology); aquifers; soil air; soil water; biodegradation; sand; groundwater; vapors; water table; California
Abstract:
... Petroleum spills often create persistent "source zones" of hydrocarbon-impacted soils that are either in direct contact with ground water or in indirect contact through soil moisture infiltration and dissolution. Understanding the natural attenuation of source zones is critical to anticipating their longevity and the future chemical composition of their associated dissolved ground water and vapor ...

6. Source Zone Natural Attenuation at Petroleum Hydrocarbon Spill Sites--I: Site-Specific Assessment Approach

Author:
Johnson, Paul; Lundegard, Paul; Liu, Zhuang
Source:
Ground water monitoring & remediation 2006 v.26 no.4 pp. 82-92
ISSN:
1069-3629
Subject:
soil pollution; petroleum; hydrocarbons; groundwater; water quality; environmental impact; remediation; vapors; groundwater contamination; California
Abstract:
... This work focuses on the site-specific assessment of source zone natural attenuation (SZNA) at petroleum spill sites, including the confirmation that SZNA is occurring, estimation of current SZNA rates, and anticipation of SZNA impact on future ground water quality. The approach anticipates that decision makers will be interested in answers to the following questions: (1) Is SZNA occurring and wha ...

Abstract:
... Results from a plume mapping study from November 2000 through February 2001 in the sand-and-gravel surficial aquifer at Dover Air Force Base, Delaware, were used to assess the occurrence and extent of chlorinated solvent mass loss by calculating mass fluxes across two transverse cross sections and by observing changes in concentration ratios and mole fractions along a longitudinal cross section th ...
