  • Mass flow sensing improves leak test efficiency

    Mass flow meters reduce risk of measurement error and provide a reliable, quantitative measurement of product quality and production process control. In the leak testing application, mass flow meters offer advantages unmatched by other instruments. Today, leak testing must be not only precise, accurate and irrefutable, but also easy-to-use, fast and efficient. With mass flow sensing, dry air ...

  • Feds propose new reg to remove leaking storage tanks from service

    With spills and leaks from storage tank systems that contain petroleum products continuing to pose significant health and environmental risks, the federal Department of the Environment proposed recently a new regulation to reduce the risk of contaminating soil and groundwater. The proposed Storage Tank Systems for Petroleum Products and Allied Petroleum Products Regulations would replace the ...

  • 99% of Oil from Leaking tanks remediated - Case study

    Spills and leaks from domestic and commercial oil tanks are a very common occurrence, caused either by the refilling of tanks or as the result of leaks. Very  often old metal tanks corrode and start leaking oil onto the ground around the tank. Also the tanks themselves become covered in dried hydrocarbons and become significantly discoloured, even black. Spilled oil can seep into the ground, ...

  • Performance-Based Specification Of Electrical Leak Location Surveys For Geomembrane Liners

    ABSTRACT Electrical leak location surveys can be a crucial part of the final quality control of geomembrane liner installations. The method has been offered as a commercial service since 1985 and is the only practical test method that can find holes in the liner after protective soil cover is put on the liner. During the past fourteen years the test method has been used on a wide variety of ...

  • Successful Pilot Test Results in Full-Scale Treatment of Large BTEX Plume

    CASE SUMMARYRefueling Station – Algonquin, IL Leaking underground storage tanks at a refueling station resulted in a benzene, toluene, ethylbenzene and xylene (BTEX) plume in the underlying sand/gravel aquifer. The plume covered 1-acre and extended 390 feet downgradient from the source area, with a total BTEX concentration exceeding 24,000 parts per billion (ppb). In an ...

  • Rapid Analysis of Petroleum Hydrocarbons (TPH) in Soil and Water by Infrared Spectroscopy

    In 1988 the US EPA estimated that there were 3 to 5 million underground chemical storage tanks (UST’s) in the United States, of which up to 1% would develop leaks every year. In response to growing concerns about the quality and future availability of safe drinking water, federal and state programs have begun to systematically replace virtually all UST’s installed before 1986 either with above ...

  • Gas process automation

    Problem: Many relatively simple industrial or laboratory processes that require control of flow or pressure can be greatly improved with automation. Using a mass flow controller to control a certain gas flow rate, for instance, is far more precise and has a faster speed of response than manually adjusting a needle valve while consulting a pressure gage. Such processes can be automated ...

  • On-Site Analysis of Gasoline Range Organics (GRO) in Soil and Groundwater Using Field Portable Purge and Trap GC / FID / PID

    Although leaking underground storage tanks account for the majority of gasoline contamination in soils and groundwater, other events such as accidents during product transportation or delivery are also significant. Spill clean-ups and tank replacements have an immediacy to them due to the very steep relationship between delay and cost. Since gasoline is highly mobile in the environment, it is ...

  • Development of resistivity probes for continuous monitoring of pollutant in porous media

    In this study, an attempt has been made to develop resistivity probes and an experimental setup capable of simulating the field conditions concerned with migration of pollutant through the porous media. The porous media chosen for the present study is commercially available uniformly graded sand; while Sodium Chloride solution was considered as the pollutant. For the continuous monitoring of ...

  • Typical Sensor Location Considerations

    The sensor mounting location within a space may be dependent on many variables. There are no specific formulas since each application will have it’s own determining factors and priorities. These include, but are not limited to: source of gas: Is the source a combustion exhaust from a vehicle or furnace or a vapour from a tank spill, pipe leak, or faulty valve? density of ...

  • A Simplified Procedure for the Determination of TPH’s in Waters and Soils Using the HC-404 System

    The determination of Total Petroleum Hydrocarbons (TPH), greases, and lubricant residues are important environmental and industrial tests. Fuel and lube oils can be determined in water and soils to track spills and storage tank leaks, while many military and industrial situations require certain components (gas regulators, space shuttle components, weaponry parts, etc.) to have a maximum limit of ...

  • In-Situ Treatment - Funnel & Gate System - Case Study

    Problem An asphalt testing facility, in operation for many years, closed in the early 1990s. A subsequent environmental assessment revealed that an underground storage tank, used to hold common cleaning/degreasing solvent for use during testing, had developed a leak and had to be abandoned. The storage tank and soil in the immediate vicinity was removed as the first step to remediate ...

  • Case study - EPH in soil with No. 6 fuel oil

    No. 6 fuel oils (heavy fuel oil, bunker C oil) is often used in industry for heat, steam or power generation. A consultant used Sitelab to investigate two different spill sites contaminated with subsurface plumes of NAPL resulting from leaking underground storage tanks (USTs). Soils were collected from borings using a drill rig and field screened for their EPH aromatic content. Split samples ...

  • Case study – BTEX contamination - Kentucky

    In 1992, remedial activities began at the Shively Service Center located in Radcliff, Kentucky. After the leaking underground storage tanks were removed from the site approximately 1,500 cubic yards of BTEX impacted soil was excavated and disposed off-site from the tank pits. Based on the review of historical sampling activities it was believed that the majority of the impacted soils were removed ...
