I learned recently that approximately 40% of the world’s food is cultivated in irrigated areas and that 10% of the world’s population consumes food irrigated with wastewater.
This realization made me wonder: how safe is it to irrigate crops with wastewater? And, after a bit of research, it appears that there … Read More
Since 1993, the equipment rental industry has more than doubled in size—from $11.2 billion to $22 billion. Just 10 years before that, equipment rental was a $1.1-billion industry.
Industry experts say that a combination of factors is responsible for this sizable boost, most notably the construction booms of the late 1980s … Read More

Among researchers who study the potential effects of rising sea levels, and among the city planners in coastal areas who are actively trying to come up with viable plans for their communities, the idea of retreat is catching on. The alternative is to build physical defenses—costly sea walls, levees, or … Read More
Where do you stand on climate change? Is the issue settled? Do you think there are still some uncertainties to be cleared up?
Last week I wrote about a recent report on the science behind sea level rise; the authors of that report explain the models and data they’re using to … Read More
Nuclear generation makes up about 20% of the United States’ energy supply. While nuclear plants are in-line with current carbon-free environmental goals, positive attributes, such as grid stability and consistent base load are often overlooked. As a result, today, they are struggling to compete.
In May, at a US Department of … Read More
Last week, as you’ve probably heard, five people in Michigan were charged with involuntary manslaughter for circumstances related to the Flint water crisis—specifically for their failure to sound the alert about increases in the number of cases of Legionnaires’ disease.

Last Sunday’s New York Times article, “It’s No Accident: Advocates Want to Speak of Car ‘Crashes’ Instead,” hit the nail on the head by suggesting that people, not some intergalactic demonic force, are responsible for all but 6% of the 38,000 roadway fatalities in 2015. What’s behind the 6% not … Read More
Many cities and some states have banned single-use plastic shopping bags. The next item on the list? It could be the plastic drinking straw.
Cities and states that have banned plastic bags have done so for several reasons—they’re not biodegradable; they contribute to landfill waste—but one of the most-cited has been … Read More
“The current reality of smart cities is that there aren’t any,” asserts a recent Scientific American article. And it’s true. While there are a number of cities with “smart” elements, such as networked cameras and traffic signals or daylight-sensing streetlights, most of today’s smart cities are made up of smart … Read More
It’s estimated that 70% of freshwater withdrawals worldwide are for agricultural use. Although some see recycled wastewater as a potential solution component to global water scarcity issues, the costs of treating wastewater—to remove contaminants, reduce crop-damaging salts, and to meet health standards for reuse—often present financial limitations.
A new economic model … Read More
In May 2016, the governor of Colorado signed a bill legalizing rain barrels. Before then, the capture and use of rainwater, even on so small a scale, was illegal in Colorado.

What exactly does “navigable” mean? Vague definitions of which bodies of water are protected by federal agencies have confounded policy makers for decades. In 1972, the Clean Water Act gave federal authorities the power to regulate pollution in “navigable waters.” The job of determining which of those waters the policy … Read More
This is a question many have asked, particularly over the past decade as the concern for energy resources again reared its ugly head.

When it’s time to replace a water heater—or put one into a newly constructed building—facility managers can choose between the traditional storage tank heater or a tankless water heater.
Tankless water heaters, also known as demand-type water heaters, can provide endless hot water only as it is needed and used, points … Read More
Satellite radar measurements provided by interferometric synthetic aperture radar, or InSAR, can detect subtle, millimeter-scale changes in ground elevation as areas gain or lose groundwater. Researchers have recently utilized the technology to quantify the effects of California’s drought. And in an unexpected twist, they also detected shifts due to policy … Read More
We’ve talked a lot on this website and in Erosion Control magazine about invasive species, from kudzu to the salt cedar beetle. Sometimes non-native species are introduced into an ecosystem deliberately: as ornamental plants, or vegetation used to shore up eroding hillsides, or animals and insects used as biological controls … Read More
For the most part, antibiotics play a positive role in the modern world. They help combat infection and keep us healthy.
