  • Case study - Dredge site testing PAHs in sediment

    The Grand Calumet River is a tributary located in Northwest Indiana, which flows into Lake Michigan. Years of industrial pollution caused by nearby steel mills, petro-chemical plants and oil refineries have contaminated the river with oil and other pollutants, which threaten human and ecological health in this watershed. The primary contaminants of concern are carcinogenic Polyaromatic ...

  • Effectiveness of priority PAH removal in a water coagulation process

    The paper presents results of research on the removal of priority hazardous polycyclic aromatic hydrocarbons (PAHs) (anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[g,h,i]perylene, indeno[1,2,3-cd]pyrene) from water in the coagulation and sedimentation process. Coagulants chosen for the analysis were aluminum(VI)sulfate and two pre-hydrolyzed coagulants – ...

  • PAHs in Parking Lot Sealcoats - Case Study

    There is growing concern - and regulations in the works - over the use of sealcoating products due to their high PAH content.  In the United States and elsewhere, most sealcoats are made from coal tar which can be toxic to aquatic life and threaten public water supplies from rain and runoff.  Sample was collected from a freshly treated parking lot in Seabrook, New Hampshire. The ...

  • PaHs: Beazer East, Inc. - Denver, Colorado, USA

    Project In Situ Biogeochemical Stabilization (ISBS) of Creosote/Pentachlorophenol NAPLS Using Permanganate Summary A growing number of non-aqueous phase liquid (NAPL) removal technologies have been promoted commercially over the past few years, including: thermal-enhanced recovery, surfactant flooding, steam- and temperature-enhanced extraction and others. It is ...


  • 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% ...

  • Heavy metals, PAHs and toxicity in stormwater wet detention ponds

    Concentrations of 6 different heavy metals and total polycyclic aromatic hydrocarbons (PAHs) were determined in stormwater runoff and in the pond water of two Danish wet detention ponds. The pond water samples were analyzed for toxic effects, using the algae Selenastrum capricornutum as a test organism. Stormwater and pond water from a catchment with light industry showed high levels of heavy ...

  • Extraction of Sediment using the SpeedExtractor E-916 for the Determination of Polycyclic Aromatic Hydrocarbons (PAH)

    Polycyclic aromatic hydrocarbons (PAH) are chemical compounds that consist of fused aromatic rings and do not contain heteroatoms or carry substituents. They are of concern because some compounds have been identified as carcinogenic, mutagenic and teratogenic. Sediment samples origin from a round robin program (SETOC 2008/4, Wepal, Wageningen University) were extracted according to EPA 3545A with ...

  • Exposure time–dependent effects on the relative potencies and additivity of PAHs in the Ah receptor‐based H4IIE‐luc bioassay

    In the present study, relative potency factors (REPs) of 16 individual polycyclic aromatic hydrocarbons (PAHs) were investigated using the H4IIE‐luc bioassay. Exposure time‐dependent effects on the REPs were examined using 24, 48, and 72 h of exposure. Seven different mixtures of PAHs were tested for additivity at an exposure time of 24 h. Three of the PAH mixtures were also studied at 48 and ...

  • Use of PAHs RaPID ASSAY kits for semi-quantitative screening consistent with SW-846 Methood 4035

    BACKGROUND The Methods Section of the EPA Office of Solid Waste (OSW) has stated a need for more rapid, less expensive field screening procedures that do not compromise the accuracy of contaminant evaluation. The OSW screening approach incorporates a single point threshold or multiple individual point discriminators giving results in semiquantitative ranges lying between these points. SDI ...


  • A Comparison of Two Media Filtration BMP Treatments for the Removal of PAHS and Phthalates from Roadway Runoff

    Urban runoff is a major contributor to the degradation of our urban streams, rivers, and lakes (Pitt, 1995). Organic pollutants, such as PAHs and phthalates, in urban stormwater can contribute to receiving water degradation (EPA, 1983). A study in Rhode Island’s Narragansett Bay watershed found that urban runoff accounted for 71 percent of the total inputs to the bay for higher molecular weight ...


  • Predicting toxicity to Hyalella azteca in pyrogenic‐impacted sediments – Do we need to analyze for all 34 PAHs?

    PAHs are major drivers of risk at many urban/industrialized sediment sites. The USEPA currently recommends using measurements of 18 parent + 16 groups of alkylated PAHs (PAH‐34) to assess the potential for sediment‐bound PAHs to impact benthic organisms at these sites. ASTM Method D7363‐13 was developed to directly measure low‐level sediment pore water PAH concentrations. These concentrations ...
