Recent papers in groundwater remediation
Computational cost is a critical issue for large-scale water resource optimization under uncertainty, since time-intensive Monte Carlo simulations are often required to evaluate over multiple parameter realizations. This paper presents an efficient approach for replacing most Monte Carlo simulations with efficient surrogate models within a noisy genetic algorithm (GA). The surrogates are trained ...

Former Wellsite Sump - In-Situ Chemical Oxidation - Case Study
Former admixed drilling sump at an abandoned wellsite. Surficial soil impacts were excavated and removed from Site. Shallow groundwater limited excavation and required in-situ treatment method for remaining soil impacts and groundwater impacts. Lithology of the target treatment zone is saturated silty sand, creating a pathway for contaminant ...

Drycleaner site: Houston, Texas
Site Summary: Historical dry cleaning solvent spills from an active dry cleaners contaminated soil and ground water under a shopping center. The migration of contaminants in shallow ground water spread contamination from under the building into a residential subdivision. The resulting plume of contaminated ground water was more than 1,000 feet long. Geology and Hydrogeology The geology of the ...

Residential Property UST Spill - In-Situ Chemical Oxidation - Case Study
An underground storage tank containing heating oil had leaked off-site onto a residential property and migrated under the building foundation. Impacts under the basement resulted in vapour intrusion in the basement and free product in property ...

Groundwater remediation using simulation-optimisation approach: A review
Optimal design of a remediation system has been an active and important area of research since the past several years due to its potential to reduce the remediation cost substantially. The paper presents the state-of-the-art for application of simulation-optimisation approach to design an optimal groundwater remediation system. In the simulation-optimisation approach, the researchers have used ...

Case study - Reactive barrier wall project update
Reactive Barrier Wall solves space and on-going activity problems during remediation project “Name Removed”, was contracted to install a passive reactive barrier wall in “Name Removed”. The wall was designed to remediate groundwater containing tetrachloroethylene (TCE). What made this job unique was the site location. Installation would occur in an operating commercial ...

How to Remediate under an Intersection with Horizontal Wells
Roadway intersections within urban settings are arguably some of the most challenging areas for subsurface remediation. Many consultants tasked with remediation of challenging sites such as these become frustrated by the inability of a vertical remediation system to influence the area of concern and/or they are anxious that they will not efficiently bring their clients’ sites to closure. ...
