water quality

In 2015, the U.S. Environmental Protection Agency released a report finding 457 fracking-related spills in eight states between 2006 and 2012. Last month, a new study tallied more than 6,600 fracking spills in just four states between 2005 and 2014. But, as usual, the numbers only tell part of the story. Not every spill counted in that new number represents a spill of potentially harmful materials or even a spill that made contact with the environment. In fact, the study’s goal wasn’t to tally an absolute number of fracking spills. Instead, researchers set out to collect available spill data…
Lead isn’t the only toxin threatening the safety of community drinking water. A recent study on water located downstream from a West Virginia fracking disposal site uncovered levels of endocrine-disrupting chemicals high enough to adversely impact the aquatic animals living there. And that means human health could be at risk too. “We can’t make any direct (human health) assumptions about this particular water,” said study co-author Susan Nagel, an associate professor in the University of Missouri School of Medicine’s Division of Obstetrics, Gynecology and Women’s Health. “But we certainly…
For years, scientists have described climate change as a slowly emerging public health crisis. But for many, it’s difficult to imagine how a complex planetary phenomenon can impact personal well-being beyond the obvious effects of natural disasters, which climatologists say will happen more frequently and intensely as the world warms. That disconnect is what piqued my interest in a new study on old infrastructure, heavy rainfalls and spikes in human illness. Drinking water quality is among the many adverse effects that climate change is expected to have on human health. But what exactly does…
This is the time of year, spring, when a lot of people switch to drinking bottled water instead of tap water. They do this because in their particular area the tap water seems to "go bad" ... usually it is a mild smell or a slightly icky taste. This makes people fear their tap water, so they go to the store and buy bottled water. What has happened in many cases is that the local municipal water supply has done everything it can reasonably do to clean up and make nice the water that comes out of your tap, but there is this slight taste or smell because in the spring, that is what water does…
Forty years ago today, the Clean Water Act was enacted. Since then, US waterways have gotten cleaner – but some people seem to be forgetting why we need regulation like this in the first place.  The Act aimed "to restore and maintain the chemical, physical, and biological integrity of the Nation's waters" by establishing a system to regulate municipal, industrial, and other discharges into waterways. EPA explains: The CWA set a new national goal “to restore and maintain the chemical, physical, and biological integrity of the Nation’s waters”, with interim goals that all waters be fishable and…
Jet-lag and grading fatigue (plus being on the other coast for three days) mean that I haven't had much time lately to sit down with the sprogs and have a conversation about science. However, Casa Free-Ride presents me with clues which suggest that the Free-Ride offspring have been thinking about science. The younger Free-Ride offspring's backpack, for example, yielded a water quality report: The dry-erase calendar on the door between the kitchen and garage still retains visual aids from a conversation Dr. Free-Ride's better half seems to have had with the sprogs about genetics: And, on…
