  • EPA Method 415.3 - Determination of TOC in Source Water and Drinking Water

    Method 415.3 states that the measurement of Total Organic Carbon (TOC) and DOC must use a TOC instrument that oxidizes organic carbon in the water to create carbon dioxide gas, which is then measurable. The instruments are required to use one of two basic oxidation methods – either through combustion with an oxidizing gas, or through chemical oxidation with persulfate promoted by either UV ...

  • U.S. EPA approves first enzymatic method for SDWA reporting of nitrate

    The US Environmental Protection Agency periodically updates methods laboratories can use for protecting the quality of the nation's drinking water.  The Safe Drinking Water Act office of the EPA published its list of Alternate Test Protocols (ATP) in the Federal Register in July 2016. ...

  • Trace Analysis of PAHs using EPA methods 3541, 3545 and 8100

    The Extraction System B-811 and the Syncore Analyst parallel concentrator from Buchi as well as the Pressurized Solvent Extractor from Applied Separations were evaluated for the pretreatment of samples containing PAHs. Recoveries of extraction and subsequent concentration using acetone-n-hexane (1+1) were 70-95% for 2 ring and 90-100% for less volatile 3-5 ring PAHs. A good precision (95% ...

  • Will your oil in water analysis method match the regulatory method?

    Anyone involved in field analysis of oil in water will continually get the question “Does your equipment match the regulatory method?” While the amount of oil in water is highly regulated -- it can also be a challenging measurement. It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the ...

  • Quantitative Determination of Volatile Organic Compounds in Drinking Water by EPA Method with Headspace Trap GC-MS

    Volatile Organic Compounds (VOCs) refer to a group of easily vapourised organic compounds. Under atmospheric pressure, these compounds boil below 250C. Studies have shown that prolonged exposure to the VOCs could increase the risk of various health problems, such as cancer. VOCs are commonly present in gasoline, dry cleaning solvents and degreasing agents. Due to improper storage, disposal or ...

  • Analysis of Mercury in Wastewater by Microwave Digestion Followed by ICP/MS: Comparison to EPA Methods Approved at 40 CFR 136.3

     ABSTRACT As a cost-saving measure, the use of an existing microwave digestion system and ICP/MS instrument was investigated for the analysis of mercury in domestic wastewater, industry effluent, storm water, and other aqueous matrices analyzed under the City of Portland’s various NPDES permits. A formal alternate test procedure application (ATP) study was undertaken to add total ...

  • Shimadzu Guide to US EPA Method 8260 for analysis of volatile organic compounds in groundwater and solid waste

    Environmental contamination has been at the forefront of government policy and regulation since the US EPA was established in 1970. Over the years the US EPA has developed, published, and updated multiple methods for analysis of environmental pollutants, and single-quadrupole gas chromatography-mass spectrometry (GC/MS) has long been the technique of choice for determination of volatile ...

  • Improved performance in the analysis of drinking waters and wastewaters by U.S. EPA Method 200.8 with an SC-FAST System

    U.S. EPA Method 200.8 contains a lengthy, detailed description of procedures, both required and recommended. A summary of the experiments that must be performed to establish the performance of the instrument, along with a 10-step daily analysis procedure, can be found in Table 1 (Page 2). Instrumental Conditions A PerkinElmer® ELAN® 9000 ICP-MS was used for the ...

  • Development of the methods and procedures for environmental life cycle assessment and practical use possibilities

    ABSTRACT The report provides the overview of current development activities on life cycle assessment (LCA). It also gives the outline of opinions and assumptions on LCA use in practice, and the relation of LCA research and practical application of LCA. Respecting the multi-disciplinary character of LCA, it can be the basic framework for environmental assessment consisting of many other ...

  • 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 ...


  • 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 isues GHG BACT guidance

    Beginning in 2011, major sources of greenhouse gas (GHG) emissions that trigger Prevention of Significant Deterioration (PSD) permitting must implement Best Available Control Technology (BACT) for GHG emissions from new and modified sources. EPA has issued a variety of guidance in an attempt to clarify the BACT determination process for GHG emissions from common stationary sources:1 EPA’s ...
