Drinking Water Analysis Application Notes

  1. 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
  2. Application Note: Miami Conservancy District Uses Nitrate Screening As Conjunctive Management Tool
    Tasked with monitoring a watershed covering nearly 4,000 square miles, almost 2,300 miles of rivers and streams, and a huge aquifer that provides drinking water for more than 1.2 million people, water quality monitoring specialists at the Miami Conservancy District (MCD) in Dayton, Ohio, have their hands full.

  3. Chlorine Method For UKAS Accreditation And DWI Compliance At Welsh Water

    In 2013 the Drinking Water Inspectorate for England & Wales announced that water samples collected in England and Wales must be tested in a laboratory that meets specific standards for drinking water sampling and analysis. At the time of the new instruction, the chlorine method employed at the Welsh Water Bretton laboratory was unable to meet these requirements, notably for the prescribed limit of detection. This prompted the laboratory to investigate new analytical options for monitoring residual chlorine.

  4. Determination Of Pesticide Residues In Tea

    In 2012, Americans consumed well over 79 billion servings of tea, which is just over 3.60 billion gallons.

  5. Bottled Water Industry: Liquid Analytical Solutions

    Americans consume more than 9.1 billion gallons of bottled water annually - an average of twenty nine gallons per person every year. 

  6. Application Note: Using Real-Time Telemetry For Ecological Monitoring Of Coastal Wetlands
    The Grand Bay National Estuarine Research Reserve (NERR)in Mississippi is one of 27 protected estuarine reserves across the United States. By YSI
  7. The Importance Of Measuring Total Organic Carbon

    Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.

  8. Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution

    The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

  9. Application Note: YSI Real-Time Water Quality Monitoring And The IPSWATCH-EMPACT Program
    The Ipswich and Parker Rivers watersheds lie only a short distance north of Boston, MA. The first settlements in these watersheds began in the early 1600s. Since that time, residents have relied heavily on the natural resources of the Parker and Ipswich Rivers, their coastal estuaries and Plum Island Sound, which is known as the Great Marsh. This ecosystem has been designated and protected by the Commonwealth of Massachusetts as an Area of Critical Environmental Concern (ACEC).
  10. Accurately Measuring Network Leakage

    The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.
