In the hot, dry Middle East, where populations are growing rapidly and all major rivers cross political borders, water has become a focal point for escalating violence.
When I attended the U.S. EPA-hosted PFAS Summit held at the Horsham, PA high school auditorium on July 25, 2018, the education I received from state and municipal leaders focusing on the local problem was more than just a professional briefing. It was ominously personal, due to the fact that the Water Online editorial office where I work and drink water every day is served by a utility sitting smack-dab in the middle of one of the most concentrated PFAS hotspots in the U.S.
Sorting through practical, legal, and environmental considerations related to Michigan House Bills 5752 and 5753 — proposed oversight for onsite wastewater treatment systems
Jon Loveland, Global Practice Leader - Alternative Water Supply at Black & Veatch, shares insight on a major development for membrane bioreactor (MBR) systems and potable reuse.
The Environment Working Group (EWG) recently released a report that claims up to 110 million Americans could have drinking water contaminated by PFAS (per- and polyfluoroalkyl substances) — much higher than the previous estimate of 16 million affected Americans.
Turbidity, a measure of the cloudiness or haziness of a fluid, was originally intended as a qualitative measure of the aesthetics of drinking water. It is not a measure of actual particles in the water; it measures how much those particles affect light being transmitted through the water, or how that light reflects off particles in the water. Today’s turbidity designs and methods have been regimented in an attempt to bring quantitative consistency to the measurement for both aesthetic and pathogenic qualities of drinking water.
Turbidity measurement is both a nebulous, oft-misunderstood concept and the master link in a chain of events affecting U.S. EPA drinking water compliance. It can influence, or be influenced by, almost every other link in a water treatment process. Here is a quick overview of turbidity’s relationship to drinking water compliance standards and some tips for keeping a water treatment process in balance.
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.
One of the many travesties in the failure to properly protect drinking water in the United States is EPA’s decades-long inability to set an enforceable drinking standard for perchlorate, a chemical that harms the thyroid — critical for normal growth and development — and that contaminates drinking water systems serving over 17 million people in the U.S.
By now, just about everyone in the U.S. has heard about Flint, Michigan’s water woes. Despite the many issues raised by that incident, urban water systems are not the sole reason the 2017 Report Card from the American Society of Civil Engineers gives the U.S. drinking water infrastructure an overall “D” grade. Hidden within that disheartening rating are the harsh realities faced by rural water systems.
