Potassium Permanganate (KMnO4) is a strong oxidizer used in the water industry for reduction of organics in raw water. It is also used for control of zebra mussel problems at raw water intake structures. Continuous monitoring of low permanganate concentrations allows operators to adjust chemical feed rates and achieve target values. Chemical feed problems that result in either too little or too much residual can be quickly identified and corrected.
The Q46H/83 eliminates this problem by employing a measurement method in which the sensor never comes into contact with the sample. In operation, water containing permanganate is mixed with pH buffer and potassium iodide solutions. Permanganate oxidizes the iodide to iodine (I2), and the resulting I2 is stripped out of solution and measured using an I2 gas sensor. This “gas phase” measurement  technique eliminates MnO2 sensor fouling, resulting in a system capable of providing long term reliability.

The Q46H/83 Permanganate monitor consists of two main components, an electronic display unit and a chemistry module.  The  chemistry module contains sample and reagent pumps, sample handling systems, and the gas sensor that provides the final measurement.  An inlet overflow assembly attached to the bottom of the chemistry module is where the inlet sample line and drain line are connected.  Sample inlet flows of 250-100 ml./min. are recommended to keep system response time to a minimum.  Reagent bottle holders are supplied so that reagents can be wall mounted below the chemistry system.

Volunteer Water Quality Monitoring Networks at the Heart of Citizen Science Movement

Lately, citizen science initiatives have been getting noticed by laypeople and mainstream media outlets. As everyday people become aware of ways they can get involved in actual scientific research, more of them are doing so—especially teachers and parents working with children. But this citizen science wave isn't actually a new thing. It has been growing outward from its core in volunteer water quality monitoring networks for years. Around the country, volunteers have been quietly monitoring the water quality in lakes, streams, rivers, marshes, and other surface waterways for decades. These highly successful programs have been supporting better water quality in communities across America, and in doing so have also formed the heart of the modern citizen science movement.

US Steel Dumping Chromium: Citizens Fighting for Lake Michigan, and Drinkable Water

If you remember the movie “Erin Brockovich,†you are already familiar with hexavalent chromium, a toxic substance that was contaminating the drinking water of people in California in the movie ( and in real life ). Although on the silver screen there was a very satisfying Hollywood resolution to the problem, there has not yet been such a happy ending in real life. The dumping of the hexavalent chromium by PG&E that the film documented took place in the 1950s and 1960s, although the company didn't tell anyone about the problem until the late 1980s. Based on current litigation around the Illinois and Indiana shores of Lake Michigan, startlingly little has changed.

Monitoring the Mississippi: Wild Celery, Redhorse and More

The Upper Mississippi stretches from headwaters at Lake Itasca, Minnesota, all the way to Cairo, Illinois, about 1,250 miles. It includes picturesque wilderness areas complete with waterfalls, limestone bluffs and expansive valleys. It has attracted many campers, hikers, fishing enthusiasts and people seeking to launch their favorite boats or canoes. It has also been a haven for environmental researchers. Since 2016, Jeff Houser is the Science Director for the Long Term Resource Monitoring element (LTRM) of the Upper Mississippi River Restoration Program (UMRR).  Previously, he led the LTRM water quality component from 2003 until 2016.
