  • EPA Method TO-15

    EPA Method TO-15

    EPA Method TO-15, also referred to as EPA TO-15 and TO-15, documents sampling and analytical procedures for the measurement of subsets of the 97 volatile organic compounds (VOCs) that are included in the 189 hazardous air pollutants (HAPs) listed in Title III of the Clean Air Act Amendments of 1990. TO-15 Volatile Organics are defined as compounds having a vapor pressure greater than 10-1 Torr at 25EC and 760 mm Hg.  The TO-15 target VOCs include...

  • Fence-line & Perimeter Air Monitoring

    Fence-line & Perimeter Air Monitoring

    Perimeter Air Monitoring at a site or facility may be needed or required for a number of different reasons. These include: To determine short & long-term inhalation exposure concentrations and associated health risks, both individual human and estimation of population risks. To collect empirical data for development or confirmation of air dispersion modeling. To determine if Clean Air Act (CAA) and/or National Ambient Air Quality Standards (NAAQS)...

  • Manufactured Gas Plant (MGP) Site Testing

    Manufactured Gas Plant (MGP) Site Testing

    The 19th & early 20th centuries was the height of the period when Manufactured Gas Plants (MGPs) were producing gas to light cities around the United States. The plants were located near the point of use, close to a water source required for the gas production. A number of different fuels and processes were used, giving rise to a range of residual materials. With the advent of electricity and other sources of gas, many sites were leveled and...

  • Indoor & Ambient Air Quality Testing

    Indoor & Ambient Air Quality Testing

    Ambient air and indoor air quality testing has increased over time as there has been increasing public awareness and concern over the quality of the air we breathe. The EPA has made significant improvement in ambient air quality through the Clean Air Act (CAA). The focus has moved from major sources to indoor air quality. We all spend a significant part of our lives indoors at home, at work, and in public indoor environments. Indoor air quality is...

  • Petroleum Vapor Intrusion

    Petroleum Vapor Intrusion

    Vapor intrusion occurs when vapor-phase volatile organic compounds migrate from sub-surface sources into overlying buildings. One type of vapor intrusion is Petroleum Vapor Intrusion, or PVI. This occurs when petroleum hydrocarbon vapors from gasoline or light distillate fuels, such as diesel or kerosene fuel enter a building. Hydrocarbon vapors entering indoor spaces can pose two threats; first, an immediate safety concern from potential explosive...

  • Analytical Support for Ecological / Human Health Risk Assessment Applications

    Analytical Support for Ecological / Human Health Risk Assessment Applications

    Generating useful, reliable analytical data for risk assessments, particularly ones involving sediment and/or tissue sampling programs, is the most difficult task an environmental laboratory can undertake. Contaminated sediments can present a significant challenge to achieving project-specific detection limits, given the high TOC and moisture content. This can be further exacerbated by high concentrations of both target and non-target analytes. Tissue...

  • Analytical Support for MGP Site Applications

    Analytical Support for MGP Site Applications

    Legacies of the 'gaslight era', former manufactured gas plant (MGP) sites can have a unique chemical contamination signature and, as they were often located along waterways in urban areas, can present a significant challenge to remediation. Alpha Analytical has considerable qualifications and experience working on site characterization and remediation projects, where former manufactured gas plant (MGP) operations are suspected of being the primary...

  • PCB Analysis (Aroclors, Congeners, Homologs)

    PCB Analysis (Aroclors, Congeners, Homologs)

    Traditionally, most PCB analysis has been performed by either of two approaches - aroclor analysis utilizing gas chromatography with an electron capture detector (GC-ECD) or congener/homolog analysis utilizing high resolution gas chromatography/mass spectrometry (GC/HRMS). While each approach has its advantages and disadvantages, there is a very wide gap between these techniques in terms of the type, depth, breadth, and quality of information that...

  • PAH Analysis (Alkylated PAHs, HPAHs & PAHs in Air)

    PAH Analysis (Alkylated PAHs, HPAHs & PAHs in Air)

    Alpha Analytical has considerable experience with the analysis of hydrocarbons in general and PAHs in particular. We have supported some of the largest, most demanding and highest profile hydrocarbon investigations in the world. Alpha offers a unique combination of the highest quality analytical capabiliities, as well as the capacity to process the large numbers of samples these types of projects typically generate both efficiently and in accordance...

  • PAH Analysis of Sediment Pore Water (SPME/GCMS-SIM)

    PAH Analysis of Sediment Pore Water (SPME/GCMS-SIM)

    Total PAH concentrations in sediment are generally recognized in the literature to be poor predictors of benthic invertebrate toxicity. Pore water analysis provides a better indication; however, the direct measurement of PAH concentrations in pore water has traditionally been very challenging.
