  • Use of geostatistics to evaluate the monitoring well network of a TCE plume

    This paper summarises the use of geostatistics to evaluate an existing network of wells in a groundwater monitoring program. The primary objective was to evaluate whether selective well removal would result in a comparable characterisation of a trichloroethylene (TCE) plume. For adequate characterisation, it is important to retain enough wells to evaluate areas with higher concentrations and to ...

  • Optimal design of groundwater-level monitoring networks

    Groundwater monitoring plays a significant role in groundwater management. This study presents an optimization method for designing groundwater-level monitoring networks. The proposed design method was used in the Eshtehard aquifer, in central Iran. Three scenarios were considered to optimize the locations of the observation wells: (1) designing new monitoring networks, (2) redesigning ...

  • Groundwater Plume, Source and Risk Identification Using Passive Soil Gas

    Abstract The results from sixty passive soil gas (PSG) samplers placed at a grain silo and mixed-use industrial facility with a known chlorinated solvent release aided with the rapid investigation time-schedule. The samplers were used to determine potential sources, plume extent and vapor risks in areas beyond the previous discrete soil sampling and permanent groundwater monitoring well ...

  • How to set up a groundwater monitoring test site

    When it comes to groundwater monitoring, testing the water often requires the creation of a borehole at the test site to reach the water below. The process of creating a safe and secure site for everyone involved can sometimes be a lengthy process. The size of the borehole, which drill to use and the response zone are just a few of the considerations that will need to be taken into account during ...

  • In Situ Bioremediation of Chlorinated Solvents: A Case Study

    In situ bioremediation is ongoing at a former manufacturing facility in Portland, Oregon. Shallow groundwater at the site was impacted by chlorinated solvents, primarily trichloroethene and degradation products cis-1,2-dichloroethene and vinyl chloride. In situ chemical oxidation treatment was completed in 2003 via the injection of sodium permanganate in source areas. Subsequent stimulation of in ...

  • Cost Savings with Bioremediation

    Introduction Prior operations at a former plating and hard anodizing facility in Santa Clara, California resulted in tetrachloroethene (PCE), trichloroethene (TCE), and cis-1,2-dichloroethene (DCE) impacts to soil and groundwater. In 1987, a groundwater monitoring program was implemented to monitor the plume. In 1998, CDM performed a natural attenuation evaluation for ...

  • GW monitoring in saxony

    Background During the hundred-year flood in 2002 in Eastern Germany the river “Elbe“ and a lot of rivers in the catchment area exceeded the banks and caused damages of millions within a short period of time. Often unnoticed, the groundwater level was rising extremely after a certain time. The time of rising groundwater took considerably longer than the actual flood, and caused enormous ...
