  • Decontaminating Groundwater Sampling Devices

    These studies are the second part of a two year project that examines decontaminating groundwater sampling devices. In the first year, the efficiency of various decontamination protocols was tested using small test pieces of materials that are commonly used in groundwater sampling devices. Those tests showed that a hot detergent wash and rinse followed by hot air drying (105°C) was the most ...

  • Hitting the Bull`s-Eye in Groundwater Sampling

    Many commonly used groundwater sampling techniques and procedures have resulted from methods developed for water supply investigations. These methods have persisted, even though the monitoring goals may have changed from water supply development to contaminant source and plume delineation. Unfortunately, the use of these methods can result in an incorrect understanding of the contaminant ...

  • Case study - Low-flow groundwater sampling on a nuclear site

    Nuclear licensed site use of low-flow groundwater sampling shows: Reduced time, reduced quantity of purge water – both thus reducing cost - and reduced risk of operator contact especially with potentially radioactive-contaminated purge water thanks to a self-contained enclosed system. One of the biggest headaches on site is the purge water and the expense of getting rid of it – after ...

  • Sampling and On-Site Analytical Methods for Volatiles in Soil and Groundwater - Field Guidance Manual

    Abstract: Volatile organic compounds (VOCs) are among the most frequently identified contaminants in soil and groundwater samples obtained during the investigation of suspected hazardous waste sites. Because some VOCs and their degradation products are potentially mutagenic, carcinogenic, or teratogenic, their concentrations in these two matrices are key factors in the risk assessment process. ...

  • Low Flow Groundwater Sampling Using RotaPump Inertial Lift Pump

    This article tells you how to perform low flow groundwater sampling using a portable, surface-mounted pump with no decontamination required before each use and  no chance of cross contamination between wells. An inertial lift pump moves a dedicated (stored in the well) pumping tube rapidly up and down.  A one-way valve on the bottom admits water on the down stroke and ...

  • Groundwater Monitoring Case Study

    Global has been contracted by the Michigan Department of Environmental Quality, Remediation and Redevelopment Division (MDEQ RRD) to conduct quarterly sampling at a former gas station and adjacent property located near a State of Michigan owned public assess site to Torch Lake. The purpose of the sampling is to assure that there are no impacts to the surface water located downgradient of the ...

  • 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 ...

  • Groundwater arsenic in Chimaltenango, Guatemala

    In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site ...

  • MTBE Groundwater BioTreatability Study

    The following graph illustrates the analytical results of a bio-treatability study conducted on MTBE. A two-liter groundwater sample was collected from the client's service station in western Pennsylvania. We tested three different combinations of microbe and nutrient products in order to determine which products are the most effective. The results indicate that MTBE can be bioremediated by our ...

  • Radon distribution in groundwater of Taiwan

    Radon levels were surveyed in 517 monitoring wells constructed in five major groundwater areas of Taiwan. The radon concentration in groundwater samples varied in a wide range from below the detection limit of 18 pCi/L up to 1,100 pCi/L. A worldwide comparison of reported groundwater radon levels was conducted. Overall radon levels in Taiwan groundwater are relatively low compared to other ...

  • Technical Bulletin: Multilevel Sampling

    The topic of this CL:AIRE Technical Bulletin is multilevel sampling systems for characterising contaminated groundwater. Contaminated groundwater can present considerable problems for landowners: it can occur at significant depth, sources of the contamination are not often obvious, it can migrate from one property to another, and groundwater flow directions can be altered due to seasonal ...

  • Analysis of TNT and RDX in groundwater

    MATRIX: Water ANALYTE: TNT and RDX LIMIT OF DETECTION: TNT 1 ppb (mg/L), RDX: 5 ppb (mg/L) BACKGROUND: This application describes a field screening method for determining TNT and RDX concentrations in water. The method uses solid phase extraction to remove and preconcentrate the analytes from water. In the method, a 2 ...

  • Bioremediation of groundwater at a gas station in PA

    The target compounds detected in the source area wells (MW-1, OW-A, and OW-B) decreased during the eight quarterly sampling events performed since the injection of HydroRemed. These compounds included benzene, ethylbenzene, naphthalene, toluene, 1,2,4-TMB, and 1,3,5-TMB. During the last three quarters (November 2011 to May 2012), the only target compounds 1,2,4-TMB and 1,3,5-TMB, were drastically ...
