For many MSPs, integrating their security solution with their remote monitoring and management (RMM) and professional service automation (PSA) platforms is essential for doing business. Together, these platforms help lower the cost of keeping up with each client, ensuring profitable margins for a healthy, growing business.
Last year, the National Oceanic and Atmospheric Administration (NOAA) recorded the largest hypoxic zone in the Gulf of Mexico since monitoring began 32 years ago. Hypoxic waters, often referred to as dead zones, have dissolved oxygen concentrations of less than 2-3 ppm. They are caused by eutrophication or excess nutrients that promote algal growth in water bodies. As algae decompose, they consume oxygen creating dead zones.
Mohawk Valley Water Authority (MVWA) in New York State is a progressive supplier of potable water. With source water from the Adirondack Mountains, MVWA works to improve on nature and provide superior water quality, always striving to meet or exceed drinking water standards.
The water industry has made progress in developing numerical values for screen-capture ratings under specific conditions. One such example is the UK Water Industry Research (UK WIR) standard. Its methodology is sound in measuring capture rate for a specific screen in a channel for a specific time and set of conditions. However, the measurements provided in these studies cannot be assumed to represent the performance of that screen in any other wastewater treatment plant or even in the same channel in a different time or season.
Ozone disinfection has long been a critical process in the wastewater treatment industry. And, because ozone is relied on so heavily to oxidize a wide variety of potential wastewater contaminants, water quality analysis during the disinfection process is paramount. Once the ozone process itself is understood, its water quality ramifications and the quality parameters that offer insight into its efficacy can be analyzed and taken into account.
There are many options for ensuring accurate billing of water used at established industrial customer locations. But how do municipalities or businesses keep track of water availability and use for intermittent applications or movable access points? We spoke with McCrometer, Inc.’s Marc Bennett for insight into how water utilities and industries can efficiently track and allocate water use for billing or internal accounting purposes in such ad hoc applications.
Total nitrogen (TN) has become a compound of concern because of its impact on eutrophication on water sources. And as more states begin to set limits for TN, accurate testing becomes paramount. Unfortunately, multiple labs and variable test procedures can lead to disparities in final results. Many of today’s test methods are also time consuming, expensive, and even unsafe for lab technicians to use.
Automated metering systems (AMSs) or “smart meters” can provide valuable data for electric and water utilities. Data analytics can be used to improve customer service, boost conservation, monitor the system, and even forecast demand. An ultimate goal might be to eventually monitor everything from streetlight intensity to fire hydrants.
A lot has changed over the past 15 years. Back in the early 2000s, many utilities weren’t interested in understanding what was in their water beyond the contaminant and disinfection byproduct levels they were regulated to comply with. But as Pat Whalen, President and CEO of LuminUltra, explains in this ACE 2018 Water Talk interview, a steady stream of ongoing education and the modern data storage and analytics that cloud computing provides, has developed some rabid fans eager to explore the microbiology of their water systems.
Recently, Ohio Governor John Kasich issued an executive order allowing the Ohio Department of Agriculture to set requirements for storing, handling and applying manure as well as nutrient management plans in an effort to reduce nutrient pollution and algal bloom growth in Lake Erie. The order is set to affect 7,000 farms across 2 million acres.
Water professionals must plan and budget to meet new regulations on the horizon. They must find the best technology for removing emerging contaminants, such as perfluorinated compounds. Above all, they want to ensure the health and safety of their customers.

In the wastewater treatment industry, coagulation has become one of the most widespread processes for effectively separating contaminants and effluent. But coagulation is a complicated and sensitive process, one that alters the chemical balance of the wastewater in order to strip it of unwanted constituents. As in many such processes, pH plays a critical role, and treatment professionals must analyze it closely if they want to properly coagulate their product.
Wastewater service charges vary considerably across EPA regions and States. That’s one of the key findings from the National Association of Clean Water Agencies’ (NACWA) Cost of Clean Water Index. If you live in Montana, Wyoming or the Dakotas (EPA Region 8), your average service charge of $261 a year is considerably less than the $884 your fellow Americans up in New England (EPA Region 1) are paying. As you can imagine, much of the difference is to do with population size and geography.
