  • Field Test Experiments to Validate The CEN Standard Measurement Method For PM2,5

    For air quality across the European Union to be assessed on a consistent basis, Member States need to employ standard measurement techniques and procedures, following Community Directive 96/62/EC on ambient air quality assessment and management [1], and Directive 1999/30/EC (1st EC Air Quality Daughter Directive) [2], which sets the parameters specific to the assessment of particulate matter (and ...


  • A method for reducing purge volumes in deep monitoring wells: a purging experiment.

    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 samples. Lockheed sponsored a purge experiment on two deep monitor ...

  • Greenhouse gas emissions from waste management-assessment of quantification methods

    Of the many sources of urban greenhouse gas (GHG) emissions, solid waste is the only one for which management decisions are undertaken primarily by municipal governments themselves and is hence often the largest component of cities’ corporate inventories. It is essential that decision-makers select an appropriate quantification methodology and have an appreciation of methodological ...

  • EPA Increases Ammonia Emissions Control

    Concern about ammonia emissions in the air and the water continues to grow, both officially and unofficially. As U.S. Environmental Protection Agency (EPA) moves to further reduce ammonia concentrations in surface waters, common water treatment methods transform what had been a water pollution problem into an air pollution issue. Earlier this year, EPA released its draft Integrated Risk ...
