  • How to identify issues in water quality

    Water quality can mean different things to different people and therefore depends on what standard of quality one is looking for, for example, water may be fine for fish to live in but lack the quality required for human consumption. To measure the quality of water accurately, tests are carried out to identify several key indicators. These characteristics are then compared ...

  • 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 ...

  • 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 ...

  • TOC System Suitability Test for Sterile Water

    The United States Pharmacopeia (USP) specifies that total organic carbon (TOC) content be used for management of organic impurity values permitted in bulk purified water, water for injection, in addition to sterile purified water and sterile water for injection. According to USP, TOC analyzers to be used for sterile water must satisfy the TOC system suitability test using test water ...

  • Factors Affecting Oil in Water Testing Methods

    Various factors need to be considered when comparing methods to measure oil and grease in water.  Whether you are trying to meet effluent limits for an NPDES (National Pollutant Discharge Elimination System) permit, comply with oil and grease limits for the Clean Water Act (CWA), or an industry satisfying a POTW’s (Publically Owned Treatment Works) discharge permit, it is ...

  • 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, ...

  • 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 ...

  • Introduction to Environmental Testing in the USA

    Environmental laboratories practice “applied analytical chemistry” by analyzing samples using a list of potential contaminants to determine how much, if any, of the contaminant is present. These contaminants, the methods used to analyze for them, and the maximum amount of contaminant allowed in the sample are defined by regulation. This paper provides an overview of ...
