Drinking Water Analysis Application Notes

1. New Water Turbidity Measurement Technology — The US Experience
   2/3/2017

   The amount of insoluble matter present in drinking water is an essential quality indicator. Silt, sand, bacteria, spores, and chemical precipitates all contribute to the cloudiness or turbidity of water. Drinking water (DW) which is highly turbid can be unpalatable and unsafe. Consumption of even low concentrations of certain bacteria and other microorganisms can cause serious health effects. Consequently, an accurate and sensitive measurement of turbidity is vital for ensuring that drinking water is free of these contaminants.

2. Monitoring Aromatic Organics For Optimizing Coagulation
   2/1/2013

   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.

3. Application Note: Troubleshooting A pH Electrode
   1/26/2011

   Many factors affect performance of a pH electrode. When performance degrades, it is always a challenge for the analyst to identify the cause. Common troubleshooting procedures, which include evaluation of slope, electrode drift, time response, and accuracy, take considerable time. By Thermo Fisher Scientific

4. Application Note: YSI 600 Optical Monitoring System Used To Protect Lake Oconee, Georgia Water Quality
   12/27/2005
   Northern Georgia is experiencing unprecedented development; consequently, water quality in many of its watersheds is in jeopardy of severe degradation. The State of Georgia, Environmental Protection Division (EPD) has implemented an NPDES monitoring and enforcement program designed to prevent construction activities from impacting water quality
5. A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Raw And Finished Drinking Water
   4/5/2013

   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).

6. Application Note: Busseron Creek Watershed Partnership Addresses Concerns In A Rural Watershed
   1/20/2010
   As with other watershed organizations, the Busseron Creek Watershed Partnership (BCWP) exists because of surface water quality degradation. In this case, those waters drain 163,231 acres of a watershed that crosses the boundaries of Vigo, Clay, Green, and Sullivan counties in West- Central Indiana. By YSI
7. Application Note: Using Real-Time Telemetry For Ecological Monitoring Of Coastal Wetlands
   2/3/2011
   The Grand Bay National Estuarine Research Reserve (NERR)in Mississippi is one of 27 protected estuarine reserves across the United States. By YSI
8. Control Of Active Chlorine Disinfection By-Products (DBPs) Of Drinking Water Using The THM Plus Method
   4/13/2017

   Determining trihalomethane levels using standard analytical methods requires expensive equipment and highly qualified personnel, which also means that analysis costs are very high. For these reasons, trihalomethane analysis poses a serious problem for companies that supply drinking water. Read the full application note to learn how two drinking water laboratories improved quality control of water delivered to end users.

9. ABB Aztec 600 Manganese Analyzer Optimizing Manganese Removal Efficiency
   11/15/2017

   The task of managing the quantity and quality of potable water is unimaginable without online instrumentation to help water utilities to measure, treat and deliver drinking water to consumers. ABB’s Aztec 600 colorimetric and ion-selective electrode (ISE) analyzers have been designed to measure the key parameters that affect water quality – aluminium, iron, manganese, phosphate, color, ammonia and fluoride.

10. Application Note: Real-Time Monitoring-Through Swell And High Water
    6/9/2011
    Application article about water quality monitoring pontoon providing continuous data in the Burry Inlet, an estuary in Wales. By YSI
