  • Guidelines for Use of Groundwater Spreadsheet Models in Risk-Based Corrective Action Design

    For use in risk-based corrective action design, simple analytical spreadsheet models can provide a cost-effective means of predicting groundwater plume migration and developing site-specific remediation standards. Such models are therefore commonly recommended as a conservative first step in the corrective action planning process, prior to use of more complex numerical modeling methods. However, ...

  • 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 ...

  • Parameter Estimation Guidelines for Risk-Based Corrective Action (RBCA) Modeling

    For use in risk-based corrective action (RBCA) analyses, simple analytical fate-and-transport models can provide a cost-effective means of estimating exposure concentrations and developing risk-based soil and groundwater remediation standards. Under ASTM E-1739 'Standard Guide for Risk-Based Corrective Action Applied at Petroleum Release Sites,' such models are recommended as a conservative first ...


  • ITRC technical regulatory guidelines for passive diffusion sampling, 2004

    Polyethylene diffusion bag (PDB) samplers are low-density polyethylene bags containing deionized water, used to collect water samples in groundwater wells for laboratory analyses of volatile organic compounds (VOCs). PDB samplers are passive devices, relying on the movement of groundwater from the aquifer or water-bearing zone through the screen or open interval of a well. VOCs in groundwater ...

  • Minimizing risks in wastewater reuse: proposed operational principles and guidelines for South Africa

    Treated wastewater represents a significant potential source of reclaimed water for some beneficial reuses. However, public concern over the risks/health-related hazards of wastewater reuse has limited the general acceptability of reuse systems in many countries. It is important to manage the operation of recycled water systems in such a way that it will not adversely affect public health and ...

  • Contamination of groundwater and the risk to human health

    Groundwater is a major source of drinking water in many parts of the world. In industrialised countries, there is increasing concern that groundwater reserves are being contaminated by industrial effluents and the chemical pesticides and fertilizers used in intensive farming. This paper compares some of the existing guidelines for acceptable concentrations of certain common contaminants in ...

  • New Spanish regulation on groundwater protection

    On 22 October it was issued Royal Decree 1514/2009 regulating the protection of groundwater against pollution and deterioration. The legal framework of this Royal Decree is formed by Directive 2000/60/EC (WFD) in particular Article 17, and Directive 20006/118/EC. The main objectives are to prevent or limit groundwater pollution and to establish criteria and procedures to assess their chemical ...

  • Groundwater: Low-flow Purging and Sampling

    Significant timesavings, improved sample process integrity, quality assurance and minimal quantities of potentially contaminated purge water to manage - are attractive as the focus on groundwater quality sharpens and economics demand best cost-benefit based methods Water has become a vitally important resource.  Maintaining its quality and quantity and avoiding pollution are set to be ...

  • Arsenic in private drinking water wells: an assessment of jurisdictional regulations and guidelines for risk remediation in North America

    Arsenic is a known carcinogen found globally in groundwater supplies due to natural geological occurrence. Levels exceeding the internationally recognized safe drinking water standard of 10 μg/L have been found in private drinking water supplies in many parts of Canada and the United States. Emerging epidemiological evidence confirms groundwater arsenic to be a significant health concern, ...

  • Modeling Leachate Contamination and Remediation of Groundwater at a Landfill Site

    Leachate contamination of an aquifer from a landfill sitewas simulated using the groundwater flow and transport model SUTRA developed by the U.S. Geological Survey. The model calibration was performed by spatially adjusting the hydraulic conductivity in order to capture the measured hydraulic head spatial variation and then by adjusting the dispersivity and porosity match the measured chloride ...
