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.
Immediate pH Correction For Fluctuating Flow
In a number of water, wastewater and industrial process applications, pH is one of the most critical and highly sensitive analytical measurements. Examples of critical pH applications include: Reverse Osmosis (RO) systems in which a controlled feed of caustic solution is typically added to the feed stream in order to convert a portion of dissolved carbon dioxide into bicarbonate precipitate allowing for removal by the RO membrane.

Phosphate Corrosion Control In Drinking Water
Corrosion occurs because metals tend to oxidize when they come in contact with oxygenated water, resulting in the formation of stable metal oxides.
Application Note: Simultaneous Determination Of Total Bound Nitrogen (TNb) And Total Organic Carbon (TOC) In Aqueous Samples
Total bound nitrogen (TNb) consists of dissolved ammonia, nitrates, nitrites, amines, and other organic nitrogen-containing compounds. TNb measurements represent an alternative to Total Kjeldahl Nitrogen (TKN) analysis for rapid screening of industrial wastewater, drinking water,agricultural run-off, and surface waters.

Organics Monitoring (TOC)
Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small.
Application Note: YSI 600 Optical Monitoring System Used To Protect Lake Oconee, Georgia Water Quality
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
Real-Time Conductivity Monitoring Estimates Chloride Levels In Minnesota Watershed By Using The Aqua TROLL 200
Monitoring deicing chemical levels can help researchers, city governments, and regulatory agencies understand runoff impacts on surface water, groundwater, and surrounding environments.
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).
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
