For years, centralized water and wastewater treatment facilities have been the norm. Large treatment plants typically provided the most cost-effective solution, due to economies of scale. However, new technology is tipping the scales, as decentralized treatment solutions are providing improved treatment at reduced costs.
The opioid epidemic has now hit the waters of Puget Sound. State agencies tracking pollution levels in Puget Sound have discovered traces of oxycodone in the tissues of native bay mussels (Mytilus trossulus) from Seattle and Bremerton area harbors.
Controlling Legionnaires’ disease will require a universal, preventive-based approach by a bevy of stakeholders ranging from building owners to hospital administrators, from public health officials to policymakers, and from scientists to water system engineers.
California is one step closer to a more resilient and secure water future for our communities, environment, and economy thanks to the passage of two bills in Sacramento this week.
As if they don’t already face enough challenges, water treatment plants (WTPs) in the western U.S. have yet another potential problem lurking in their source water waiting to blossom when they least expect it. This specific problem comes in the form of two invasive species: quagga mussels and zebra mussels.
Desert life depends on reliable access to water. In Namibia’s stark Namib Desert, where I spent 18 months doing research for my Ph.D., wildlife concentrates around natural springs. Increasingly, animals there also rely on man-made ponds intended for livestock.
While point level measuring approaches are regarded as simple and user-friendly, they lack the capabilities of more sophisticated continuous measuring instruments.
Computational fluid dynamics (CFD) modeling was applied to a circular water storage reservoir, proving invaluable for understanding hydraulic characteristics, developing a plan for mixing efficiency, and maintaining water quality.
AWWA’s 2018-19 president, David Rager, talks about personal priorities for his tenure and the long-range challenges the industry and his organization must strive to overcome.
Growing cities are generating higher volumes of wastewater and putting a strain on clean water supplies, calling for solutions that extract value from “waste” and ensure the sustainability of resources — with the added bonus, or imperative, of protecting the environment.
