The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical changes such as elevated temperature and discoloration. While many of the chemicals and substances that are regulated may be naturally occurring (calcium, sodium, iron, manganese, etc.) the concentration is often the key in determining what is a natural component of water and what is a contaminant. High concentrations of naturally occurring substances can have negative impacts on aquatic flora and fauna.

The Future of Water Treatment

The Future of Water Treatment

Increasing regulation will correspondingly increase the demand for reliability, performance, and new features in water treatment and testing, envisions Mark Mullet, senior product manager at GE Water. It’s not going to be easy to deliver. “Corrosive applications will pose special challenges.”

He mentions alkali, chlorine gas, and products like caustic soda

EPA Announces 2016 Annual Environmental Enforcement Results

WASHINGTON – The U.S. Environmental Protection Agency (EPA) today announced its 2016 annual enforcement and compliance results, highlighted by a series of high-impact cases that are delivering environmental and public health benefits to communities across the country. During EPA’s 2016 fiscal year—which spanned October 1, 2015 to September 30, 2016—EPA

“Mildly Radioactive”

Those of us concerned with surface water quality generally keep a wary eye on the amount of nutrients entering our lakes and rivers. Nitrogen and phosphorus from fertilizers—much of it from agricultural lands, some from urban stormwater runoff—are a big contributor to algae blooms and dead zones, and in high

Maintaining an Underground Potable Water Tank

Maintaining an Underground Potable Water Tank

Underground potable water tanks can be a cost-effective way to store healthy drinking water, but only if they are maintained properly. To reduce operating costs and conserve water, tanks must be inspected, cleaned, and maintained regularly. Documentation must be accurate, consistent, easy to analyze, current, and accessible to be a

Non-Revenue Water Loss: Its Causes and Cures

“Imagine that you run a company that sells bottled water. You spend lots of money, and use lots of energy, pumping the water out of the ground, purifying it and transporting it for sale. Then, one day, you discover that a large number of bottles never make it to the

Water Reuse and Sustainability Attract Industries

Writing in its 2012 “Guidelines for Water Reuse,” EPA acknowledges that “energy efficiency and sustainability are key drivers of water reuse which is why water reuse is so integral to sustainable water management.” Furthermore, “the water-energy nexus recognizes that water and energy are mutually dependent.”

When Ag Runoff Goes Nuclear: When Should We Regulate?

At Water Efficiency magazine, we are concerned not only with the efficient transportation and use of water, but also with water-quality issues. In other words, we try to present a holistic view of water resource management from sources to users.

Earlier this year, we ran a three-part series on solving Water Quality Index

The Dark Side of HVAC

I have a quirky cat (as if that is news!)—he likes me to walk around the apartment complex with him in the evenings. He had been an indoor cat when I adopted him, and quite a chubby one, so in an attempt to get him to be more active I
