Community concern and science joined forces to investigate the mysterious decline of South Africa's Great Brak Estuary. Continuous monitoring with the Aqua TROLL 600 Multiparameter Sonde revealed that upstream dam releases meant to help were actually releasing water depleted in dissolved oxygen, harming the estuary downstream. The findings, a partnership between Anchor Environmental and the Southern Estuarine Rehabilitation Action Group, led to a new estuary management approach.
Adrian Lechel of SRK Consulting has come up with a new method for measuring transmissivity and hydraulic conductivity that’s virtually free, gives answers quickly that compare well to pumping tests, and uses the Rugged TROLL 100 Data Logger to make measurements at the end of the airlifting (clean-out) that happens when all new wells are drilled.
Liquid Control Systems manages the unique discharge monitoring needs of U.K. quarry operations with onsite gravimetric testing, In-Situ Partech sensors, and robust reporting.
The City of Appleton WWTP conducted a 90-day trial, placing ortho phosphate and low ortho phosphate analyzers from ChemScan, and two other manufacturers side by side to see which performed best.
Longtime In-Situ customer Eli Kersh uses the RDO Trio to monitor DO, temperature and conductivity and solve a customer’s persistent water quality mystery.
New South Wales wastewater treatment plants, traditionally reluctant to trust online nutrient analyzers, have found a reliable solution in the ChemScan UV-4200 Nutrient Analyzer and a valued partner in Royce Water Technologies.
After experiencing persistent water quality issues in Tadd Lake, Minnesota’s Middle Fork Crow River Watershed District partnered with Moleaer, industry leader in nanobubble technology, to conduct a proof-of-concept study investigating nanobubbles’ suitability as a chemical-free, high-efficiency treatment for poor water quality and algal blooms.
A compact, non-contact radar level sensor delivered critical insights into impacts of development downstream, challenging previous models and underscoring the need for upstream water retention strategies to accompany new construction.
