Drinking Water Analysis Application Notes

  1. Network Monitors Water Quality In Shale Gas Drilling Region
    High-pressure injection of water, sand, and chemicals that fracture shale deposits deep underground to free trapped natural gas is employed by drillers tapping the Marcellus shale beds, a geologic deposit that stretches from central New York to Virginia and contains gas believed to be worth hundreds of billions of dollars.

  2. Dissolved Oxygen Measurement

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

  3. Determination Of Polycyclic Aromatic Hydrocarbons In Seafood

    Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.

  4. A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Raw And Finished Drinking Water

    Total organic carbon (TOC) analysis is an important indicator of water quality throughout the drinking water treatment process. Raw source water is progressively treated in chemical coagulation, flocculation, sedimentation, and filtration steps to remove particulate matter and natural organic matter (NOM).

  5. The Basics: Testing RO Quality

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached.

  6. Veterinary Drug Residue Analysis Using The AutoMate-Q40: An Automated Solution To QuEChERS

    QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

  7. Disinfection By-Products (DBP) Precursor Monitoring

    Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine.

  8. Monitoring Aromatic Organics For Optimizing Coagulation

    With the increasing awareness about the negative effects of organics within the water and wastewater treatment process along with increasingly strict water quality regulations, the need for more effective organics removal is becoming more important.

  9. Application Note: Water Flows From The Golden Hills Of California
    Each morning John Johnson drives the few miles from his smalltown home in northern California to the Center at Pardee Reservoir. Nestled among the foothills of the Sierra Nevada mountain range, the reservoir is a long 100 miles away from San Francisco Bay. By YSI
