Marshall Iron & Metal in the City of Marshall, Michigan, operated as a railroad maintenance yard from 1899 to 1931 and a foundry from 1938 to 1960. Most recently, it served as an auto salvage/metal scrapyard from 1961 to 1996. Excavation and disposal of soil and debris were completed in the fall of 2015. During these activities, light non-aqueous phase liquid (LNAPL) was observed in an ...
Volcanic gases are released by active volcanoes and significantly impact our atmosphere and environment due to the air pollutants, gases, and particles they emit. The four most common types of volcanic gases are carbon dioxide, hydrogen sulfide, sulfur dioxide, and water vapour. These can be monitored via ground-based instruments so that analysts can understand more about the gases and their ...
TerraStryke Products LLC (TerraStryke) develop-distribute biostimulation additives proven to cost-effectively enhance chlorinated volatile organic compound (cVOC) biotransformation safely and completely. Our patented biostimulation additive ERDENHANCED leverages existing biogeochemical conditions to facilitate chlorinated alkane/alkene destruction. ERDENHANCED is proven to expedite residual mass ...
Geologic characteristic of property, soils, surface, and groundwater (i.e. 7.5-minute topographic maps). Aerial photographs and Sanborn Maps as available. ...
Groundwater chemistry is diverse and complicated and is regulated by both natural hydrogeochemical and anthropogenic processes. Determining the governing processes and their influence on groundwater chemistry is very important to understand groundwater quality evolution and establish reasonable water management strategies. Main cations (Ca2+, ...
Background Leakages of TCE and the subsequent groundwater contamination at an industrial facility in Adelaide have led to an ongoing investigation and remediation program conducted since 1999. This work comprised site characterisation and remediation, including borehole drilling, monitoring well installation, soil, groundwater and vapour ...
TerraStryke Remediation Products LLC (TerraStryke) develop and distribute biostimulation additives proven to enhance any bioremediation project using low- impact, cost-effective biostimulation. Background: NASA Stennis Space Center, Passive Release Sock (PRS) Pilot Study. Evaluated additive efficacy under actual biogeochemical conditions. Past Site use impacted several groundwater bearing units ...
The goal of this study was to determine the treatment efficiency of four OWS in reducing total dissolved nitrogen (TDN) and dissolved organic carbon (DOC) concentrations before discharge to groundwater and/or adjacent surface water. Piezometers were installed for groundwater sample collection and nutrient analysis at four ...
Leakages of TCE and the subsequent groundwater contamination at an industrial facility in Adelaide have led to an ongoing investigation and remediation program conducted since 1999. This work comprised site characterisation and remediation, including borehole drilling, monitoring well installation, soil, groundwater and vapour sampling, ...
Regulatory agencies often require three well casing volumes or more be purged prior to collection of groundwater samples for chemical analysis. Costs are high for testing and disposing of potentially hazardous purge water; therefore, efforts must be made to minimize waste-water volume while obtaining representative groundwater ...
(Parsons ES) was retained by the US Air Force Center for Environmental Excellence Technology Transfer Division (AFCEE/ERT) to perform an evaluation of passive groundwater diffusion sampling technology. The diffusion sampler evaluation was funded under Contract F11623-94-D0024, Delivery Order RL72, as part of the AFCEE/ERT Remedial Process Optimization (RPO) ...
In this study, the characterisation of the solid waste and the effect of the leachate from the major dumping site in Perungudi, Chennai city, on groundwater is investigated. Various physical and chemical parameters were estimated: this includes pH, total hardness, electrical conductivity, and total dissolved solids, major cations such as Ca2+, Mg2+, Na+, and K+, major anions such ...
The investigation was performed during the third year of operation and included: (1) groundwater sampling and analysis for chlorinated solvents, dissolved CH4, dissolved H2 and major inorganic constituents; (2) Fe0 core sampling and analysis by SEM-EDS, XRD, and FTIR spectroscopy for the organic fraction; (3) in ...
Methods and Instrumentation used for Investigation Late in the 1960's, efforts rose toward drillings for chemical analysis of groundwater samples and the determination of flow patterns based on piezometric levels. ...
These monitoring wells are located transverse to and along the plume axis and are screened over 12 m across the water table. Groundwater samples from these boreholes show dissolved phase contamination between 20-30 m depth, with a mixed oxygenate/BTEX plume close to the site and oxygenate-only plume further downgradient. ...
The Regional Superfund Ground Water Forum is a group of ground-water scientists, representing EPA’s Regional Superfund Offices, organized to exchange up-to-date information related to ground-water remediation at Superfund sites. Filtration of ground-water samples for metals analysis is an issue identified by the Forum as a concern of Superfund decisionmakers. Inconsistency in EPA Superfund ...
