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.
There is little doubt about the importance of taking turbidity readings as part of drinking water treatment. However, there are certain misperceptions about the associated requirements and procedures needed to confirm the validity of those readings. The major points of confusion seem to revolve around perception of the terms “approved,” “calibration,” and “validation.” Here is a quick synopsis on what you really need to know about meeting U.S. EPA Method 180.1: Determination of Turbidity by Nephelometry for accurate turbidity readings.
In the oil and gas industry, regulations and requirements to measure, monitor and report flared gases continue to expand and extend. The U.S. EPA continues to focus on enhancing regulations aimed at reducing emissions of methane and volatile organic compounds (VOCs) into the environment.
On January 1st 2017, Philadelphia’s controversial “soda tax” went into effect, adding a 1.5-cents-per-ounce on sugary beverages sold in the city. Several cities across the U.S. have enacted similar taxes in a bid to battle diet-related diseases such as obesity and fund more healthy activities within their communities.
While many water/waste water facilities stick with outdated supervisory control and data acquisition (SCADA) systems, Aguas de Saltillo in Mexico is taking a different path and accelerating toward Industry 4.0 — and is seeing numerous benefits today.
Despite evidence that often points to the contrary, many bodies of water around the country stand as prime examples of how environmental quality can be improved with the proper will and effort.
Water utility managers have a lot of responsibilities, not the least of which is to keep up with the latest in the industry—contaminants, regulations, technology, and trends. And perfluorinated compounds (PFCs) are on the horizon as contaminants that may affect the public health. Water Online spoke with Calgon Carbon about these important emerging contaminants and how best to remove them.
Angelo Mazzei has always thought locally and acted globally. Born and raised in California’s San Joaquin Valley — one of the world’s most productive farming regions — Angelo worked for his uncle’s 10,000-acre farming operation after graduating from college. There he saw a pressing need for a system that would allow farmers to safely and efficiently inject fertilizer into their irrigation water — a task made even more challenging with the 1968 introduction of high-pressure water supplies through the California Aqueduct, a 400-mile-long water conveyance system. A new approach was vital.
The City of Paramount conducted a pilot study for arsenic, manganese and iron treatment system at their Well 15 site. The onsite pilot test was designed to demonstrate the performance of the Loprest Water Treatment Company treatment process proposed for the new treatment plant.
San Jose Water Company (SJWC) provides drinking water for over a million people in the greater San Jose Metropolitan region and is a recognized leader in drinking water treatment and distribution system water quality management.
