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: 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.

Removal Of Chloramines With Activated Carbon
In order to reduce the formation of harmful disinfection byproducts in drinking water, alternative disinfectant use has become increasingly widespread. Monochloramine is a leading alternative disinfectant that offers advantages for municipal water. This tech brief details the removal of monochloramine using activated carbon.
Leak Detection Using Conductivity
Virtually all industries from food and beverage to chemical processing use heat exchangers, condensers,or jacketed vessels. Leakage of the process into the cooling water represents a loss of product and can be a source of fouling or corrosion in the cooling water system.
Application Note: Desalination Plants: YSI Instruments Monitor Flow & Water Quality At Multiple Stages
Desalination is the process of removing salt from sea water or brackish river or groundwater to make potable water. By YSI
Measuring The Chlorine Content In The Emergency Chlorination Of Waterworks
Many municipal waterworks perform no permanent disinfection of drinking water. However, in many cases
a process known as emergency chlorination takes place. The process is switched on in case of need, adding
chlorine to the drinking water as a disinfectant.
How To Install A Submersible Pump In Discharge Tubes
In the fields of water and waste water technology, submersible pumps represent a viable economic and technical alternative to conventional, dry-installed pumps. In particular, they offer a number of handling advantages during maintenance and installation work, a factor of increasing importance in times of general staff cutbacks by operating companies.
Application Note: Employing Best Water Quality Monitoring Practices To Reduce Runoff During Construction
Under proposed EPA stormwater runoff guidelines, construction site operators will be required to actively monitor or sample stormwater discharges daily. The enhanced effluent rules take effect in August 2011 for construction sites that disturb 20 or more acres and February 2014 for sites that disturb 10 or more acres, and they may stipulate a strict numerical limit of less than 280 NTU for average turbidity (sediment in water) on any day.

Analysis Of Pesticide Residue In Spinach Using The AutoMate-Q40 An Automated QuEChERS Solution
QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.
(E)-2-Nonenal In Beer
Numerous compounds contribute to changes in beer flavor as it becomes stale. One of these compounds, (E)-2-nonenal, has been investigated as a major source of the papery/cardboard flavor that develops in aged beer.
