Continuous water quality monitoring of ammonia is becoming increasingly important for plant operations and process control. Unfortunately, on-line ammonia monitors are generally very expensive, complex, and labor intensive instruments. Most are automated versions of ammonia selective ion electrodes methods better suited to laboratory measurements. Others are automated colorimetric devices or instrumental methods that are difficult to justify on a cost basis.
ATI has developed a completely new approach to on-line monitoring of ammonia that is far less expensive and much simpler than conventional monitoring equipment. The Q46N Dissolved Ammonia Monitor uses reaction chemistry that converts ammonia in solution to a stable monochloramine compound equivalent in concentration to the original ammonia level. The chloramine concentration is then measured with a unique amperometric sensor that responds linearly to chloramines while eliminating interference from excess free chlorine in solution.

Yellow perch are a species central to the culture and economy surrounding Lake Erie. With the largest commercial fishery and a prolific sportfishing industry, Lake Erie's yellow perch are a treasured study subject for environmental scientists. Daily bag limits and other public wildlife regulations rely heavily on the work of scientists like Ann Marie Gorman, one of the Fisheries Biologists responsible for coordinating ODNR ’s Central Basin Bottom Trawl Survey.
The survey, ongoing since 1990, conducts seasonal assessments of the bottom fish community in Erie. It aims to index annual recruitment and catch-at-age of yellow perch.Read More
It’s an open, dirty secret that the ocean is used as the ultimate sewage solution.
Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up.
“This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.Read More
In 2012, for maybe the first time, Lake Superior got scummy.
Visitors to the Apostle Islands National Lakeshore reported algae washing up on shore around the park.
It was a marked shift for the park, made up of a portion of the Lake Superior lakeshore and nearby islands. The water surrounding the park is cold, clear and typically low in nutrients: a combination unlikely to result in algal blooms.
But, in 2012 and again in 2018 after violent storms, major algal blooms—ones observed over multiple days—washed ashore and clogged the beaches with unsightly, scummy algae.
Not the usual suspects
The algal blooms of Lake Superior are not the algal blooms of warmer, more nutrient-rich lakes like Lake Erie.Read More
