  • Biocorrosion in drinking water pipes

    Copper is widely used in drinking water distribution systems due to its relatively low cost and favorable mechanical properties. However, copper corrosion may generate copper concentrations exceeding the thresholds prescribed by international drinking water standards. In-situ measurements performed in an actual system found that the copper mass released under flowing water conditions (pipe ...

  • The use of aquatic plant Elodea canadensis to assess toxicity and genotoxicity of sediments of the Yenisei River

    We estimated toxicity, cyto‐ and genotoxicity of bulk sediments from the Yenisei River in laboratory bioassay based on using several endpoints of aquatic plant Elodea canadensis (Elodea). The samples of bottom sediments (BS) were collected in the Yenisei River upstream and downstream of the sources of chemical and radioactive contamination. The testing revealed different sensitivities of ...

    I wanted to start off this brief technical summary with an item that appeared in the January 2009 Indoor Environment Connections publication… “Asbestos in Soil; The State of the Issue, Tom Laubenthal, Sean Fitzgerald, Alan Seagrave, P.G. In this session, Laubenthal and Seagrave will describe the nature of asbestos contamination in soil. This issue has perplexed the industry for years. What ...

  • Aerobic granule formation in a sequencing batch reactor treating newsprint effluent under low phosphate conditions

    Pulp and paper mills are under increasing pressure to minimize the discharge of phosphate to receiving waters. We investigated the operation of two laboratory sequencing batch reactors (SBR) under low phosphate conditions over a period of eight months. Performance characteristics in terms of COD and TSS removal were similar to the full-scale mill activated sludge operation, but the floc density ...

  • Bringing powdered metal blending in-house, rotary-style

    When processing powdered metal compounds for products such as gyro rotors, flywheels, counterbalances, boring bars and grinding quills, the proportion of powdered metal ingredients must be precise, and the distribution of those ingredients 100 percent uniform. Mi-Tech Metals, Indianapolis, IN, has been manufacturing products from high-density tungsten-based alloys for more than 26 years, during ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • In Situ Solidification/Stabilization

    Introduction Solidification/stabilization (S/S) reduces the mobility of hazardous substances and contaminants in the environment through both physical and chemical means. Unlike other remedial technologies, S/S seeks to trap or immobilize contaminants within their 'host' medium (i.e., the soil, sand, and/or building materials that contain them), instead of removing them through chemical or ...
