Background Domestic wastewater generally contains substantial inorganic phosphorous resulting primarily from human excrement and polyphosphates contained in synthetic detergents. Industrial wastewater may contain a variety of phosphate compounds. (Although some industrial waste may not contain sufficient phosphorous to promote the growth of the organisms used in wastewater treatment. See the application summary entitled “Nutrient Balancing” for a discussion of this issue). Po

When a product works reliably with minimal maintenance, plant operators can turn their focus to other areas of the treatment process. For more than 20 years, a municipal water facility in the United Kingdom has used the same Partech 7000i to monitor mixed liquor and suspended solids. When the unit recently stopped working, the operators naturally turned to Partech for a replacement. “Given the historic reliability of the previous unit, the customer asked if there was a new ve

Effects of Intraborehole Flows Two new research papers published in 2019, by an Australian research group led by David Poulsen, build on earlier work by McMillan et al (2014) and others in improving our understanding of the depth origin of water samples collected from long-screened and open boreholes. Background When sampling groundwater wells and open boreholes, many practitioners think no further than using sampling guidance, which is generally only suitable for use in shor

Fully or Partially Purged – Does It Matter? When taking a groundwater sample from a well or borehole , understanding just where the water sample originates within the groundwater body is critical, particularly when contaminants are present. Research by Lindsay McMillan highlights significant uncertainties in the interpretation of water quality data not only in long screen wells, but also from wells in which screens are less than 3 m in length and in which low-flow sampling is

Other water scientists ask me how we know whether the water resources in Uganda are adequate to supply all the new water wells we and others are installing. With water shortages in places like California constantly in the news in 2015, this is a question we are addressing with actual measurements of the water levels in wells we’ve installed in Uganda. Thanks to the very generous donation of electronic transducers from two manufacturers we are now collecting water level data e

Iron and manganese typically fall into the category of secondary contaminants, but they can still cause problems for municipal and private drinking water treatment systems. Iron and manganese are best known for creating unpleasant color, taste and odor in drinking water at high concentrations. While complaints from customers are never enjoyable, ongoing research is raising questions about iron and manganese's designation as secondary contaminants. Recent studies suggest that

Chloramination can be a complex topic, but our own Scott Kahle, Vice President of Process Analyzers and Monitoring, breaks it down and explains the benefits and challenges of monitoring at every stage to optimize the process. In-Situ: Scott, tell us how the chloramination process was developed? Scott:  Around the turn of the last century, scientists discovered that chlorine added to water dissipated quickly but when natural ammonia was present, chlorine lingered, and bacteria

In-Situ has announced a new line of fluorometers compatible with the company’s popular Aqua TROLL 500 and Aqua TROLL 600 Multiparameter Sondes. The line includes: Rhodamine WT, Chlorophyll a, Phycocyanin (BGA-PC), and Phycoerythrin (BGA-PE) sensors, ideal for lake and river monitoring as well as coastal studies.  The sensors will be the latest addition to the Multiparameter water quality platform, which allows for wireless data collection via the VuSitu mobile app. Overall, t

During our recent visit to Chestertown, Maryland, we found the perfect confluence of past, present and future. Founded in 1706, the town has a colonial history so rich, one half expects to see George Washington himself strolling the brick sidewalks. It’s also home to Washington College and the Semans-Griswold Environmental Hall, a state-of-the-art facility recently constructed on the shores of the Chester River to house the Center for Environment & Society and accommodate the

One sure way to get kids interested in environmental science is to feature the work of a passionate female hydrologist on National Geographic’s popular series “When Sharks Attack” during the network’s annual SharkFest. Tracy Fanara, PhD, is an environmental engineer and ocean scientist who also happens to be a telegenic spokesperson for water science. She was recently asked to return to the SharkFest series for a second season to help explain why anomaly shark bites occur. Du

In-Situ is pleased to announce that the most requested addition to the VuSitu app has arrived. Our new Graphing Assistant makes it easy to visually interpret data for better results. To help explain how it works and who will find it most useful, we sat down with Software and Solutions Product Manager Matt Trumbo and Application Development Managers Kerry Caslow, Adam Hobson and Brock Houston. In-Situ: This is exciting, Matt. Tell us why it was important to add a graphing func

The release of the seven-port Aqua TROLL 700 and 800 Multiparameter Sondes is of particular interest for coastal applications . We sat down with Brock Houston, In-Situ’s Application Development Manager for Coastal, to talk about how the addition of the Aqua TROLL 700 and 800 expands the possibilities for data collection in marine environments. In-Situ: As an application development manager, what role do you have in developing new products? Brock Houston: My role as an ADM is

smarTROLL RDO Probe System Keeps Fish Healthier and Reduces Loss In 2013, Jerry Weigel, a Fisheries Production and Development Section Leader with the North Dakota Game & Fish Department, worked with In-Situ to develop a multi-tank monitoring system for the Department’s fish transport trucks.  Since that time, both the North Dakota and Wyoming Game & Fish Departments have standardized on smarTROLL Rugged Dissolved Oxygen (RDO) systems in their transport fleets. Real-time oxyg

We sat down with Product Owner Tom Koniuta to talk about the recent release of In-Situ’s Rugged Buoy. In-Situ: Describe your Product Owner role at In-Situ. Tom: My title is Product Owner, so I make sure our designers and developers understand what they are building and for whom. This comes from market research and direct interactions with our customers and sales team.   In-Situ: What were the design priorities? Why are they important to the customer? Tom: The top priority was

In recent years, In-Situ has focused heavily on building a suite of products designed to work together to simplify continuous monitoring and remote data collection—from the seven-port Aqua TROLL 700 and 800 Multiparameter Sondes, ideal for users who need data on more parameters, to VuLink telemetry, which easily connects to instrumentation for data transmission from almost anywhere, to our most recent addition: the Rugged Buoy, a floating deployment platform for use in open w

For pond aquaculture and RAS systems, the focus of monitoring is more often on managing density in enclosed spaces. Without critical water quality data, efforts to increase yields in limited space can have devastating consequences, wiping out an entire stock before the farmer ever detects a problem. While dissolved oxygen levels are always a concern, open coastal spaces allow for more flow between pens, lowering the risk that farmers may create hypoxic conditions by increasin

The aquaculture industry is growing fast, facing constant pressure to produce more for less. Interest in fish and shrimp is increasing as people around the world recognize seafood as a great source of protein and an essential part of a healthy diet. As demand increases, farmers face a dilemma: how can they produce more product without increasing operational costs? Increasing density in a pond or tank is one way to meet rising demand and pull in profit. But this delicate busin
