  • Lab plus international interviews ITS president

    The US-based company Industrial Test Systems (ITS) is a relatively young start-up company but is already making a big name for itself in the field of sensitive yet simple-to-use kits for water testing. The dynamism of the company can be seen from their constant challenging of the status quo to see if new and improved methods of water testing are possible. The most recent example of this is the ...

  • Oil in frac water testing

    The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the wa-ter. Waiting for remote laboratory results can take several days to a week. The InfraCal TOG/TPH ...

  • Test of Raschig Super-Pak® 250 - Case study

    SUMMARY Rascliig Super-Pak 250 (RSP 250) structured packing was tested at FRI's experimental distillation unit. The packing was tested in the 4-foot (1.22 m) section of the low-pressure column with the cyclohexane/n-heptane {C^ICi) system at 4.5 and 23.5 psia (0.31 and 1.62 bar) and the o/p xylene system at 1.43 psia (0.1 bar), or 75 mm Hg. The installation and portions of the tests were ...

  • Influences on the water testing behaviors of private well owners

    Many private wells in the United States and Canada already are contaminated, or are at risk of contamination. Regular testing for pathogenic bacteria is one of the most concrete measures well owners can use to determine whether or not their drinking water quality is safe. This study explored the factors and causal relationships that influence well owner water quality testing behavior. In-depth, ...

  • Evaluation of Allowable Pressure Under Foundations

    To understand the surcharge effect on test-loading results, water-saturated loessial soils were tested by bearing plates of different sizes in open pits and boring holes. All pit bottoms were accurately prepared for experiments. The surcharge around the bearing plate with an area of 600 cm2 was simulated by special equipment. Results of field experiments showed that the proportionality limit for ...

  • Equivalence of Air and Water Permeability Tests in Evaluating Engineering Fabrics

    Permeability characteristics of civil engineering filter fabrics are currently evaluated by three types of tests: air permeability and falling-head and constant-head water permeability. Test procedures for the falling-head and constant-head water permeability tests are discussed, and results from these tests are correlated to air permeability results for filter fabrics. Several commercially ...

  • Water insecurity in Indigenous Canada: a community-based inter-disciplinary approach

    Water insecurity in Northern Indigenous communities in Canada remains a pressing problem, with multiple dimensions and health impacts. We carried out a case study of long-term water insecurity in the Southern Inuit island community of Black Tickle, Labrador, where there is no piped water and people rely on an under-funded potable water dispensing unit (PWDU) and unmonitored water sources. Our ...

  • Heavy Metals Water Testing Powered by DNA

    Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants are one prevalent type of water pollutant. They are persistent in the environment once d is charged and removal from source waters is necessary to ensure a clean drinking water supply. The problem of heavy metal pollution arises from several sources. Heavy metals such as uranium can ...

  • The Importance of Water Testing After Natural Disasters

    In the aftermath of a natural disaster, particularly earthquakes, infrastructure could be damaged and a safe source of drinking water is often not available. This may be due to damaged pipes or water supplies becoming contaminated. Our colleagues at Oxfamstate; “In the initial phases of an emergency it should be assumed that all water sources are contaminated ...

  • Importance of Air & Water Testing in Indoor Pools

    Have you ever wondered why your eyes hurt or why you have a cough after swimming at an indoor pool? We all assume that it’s from too much chlorine in the pool but that is false! If the pool staff doesn’t regularly test and monitor both the air and water indoors, the environment becomes very toxic and unsafe to everyone in the building. Water is an essential ingredient for all life as ...
