Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415
Total organic carbon (TOC) measurement is of vital importance to the operation of water treatment due to organic compounds comprising a large group of water pollutants. TOC has been around for many years, and although it is a relatively simple analysis in theory, operational efficiency is paramount.
Application Note: Busseron Creek Watershed Partnership Addresses Concerns In A Rural Watershed
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
Validation Of Environmental Water Methods On One System
Water quality laboratories across the nation are faced with both a rising level of water quality awareness amongst the general public, as well as rising costs in water quality monitoring. As a result, laboratories are looking for more efficient ways to provide higher quality monitoring.
Application Note: Vertical Profiling Safeguards Drinking Water And Sheds Light On Cyanobacteria
A search for algal toxins in North Carolina reservoirs has evolved into an ongoing early warning system for three important drinking water reservoirs—which serve two large cities—and yielded a greater understanding of the dynamics of blue-green algae, or cyanobacteria, in the state’s reservoir system.

The Basics: Monitoring Deionized Water
Years ago, high purity water was used only in limited applications. Today, deionized (Dl) water has become an essential ingredient in hundreds of applications including: medical, laboratory, pharmaceutical, cosmetics, electronics manufacturing, food processing, plating, countless industrial processes, and even the final rinse at the local car wash.
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
Application Note: Low-Flow Sampling Of Water Quality Parameters Used In Determining Groundwater Stability
In April 1996, the U.S. EPA developed and published a document entitled Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures. The document states that “the most common ground water purging and sampling methodology is to purge wells using bailers or high speed pumps to remove 3 to 5 casing volumes followed by sample collection.” Adverse impacts can occur through this method affecting sample quality by increasing levels of turbidity. These problems can often be mitigated by using low-flow purging and sampling to reduce sampling-induced turbidity. By YSI
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.
ABB Aztec 600 Manganese Analyzer Optimizing Manganese Removal Efficiency
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.
Application Note: YSI Water Quality Monitoring Buoys Help Connecticut DOT Protect The Housatonic River
When replacement of the Sikorski Bridge spanning the
Housatonic River was authorized, Paul Corrente and the
Connecticut Department of Transportation (CT-DOT) set
about the design and development of a water quality monitoring
program to monitor the contractor’s in-water activities to
insure full protection of
the river from perturbation
