In West Virginia, a coal cleaning chemical, MCHM, had contaminated
the water and has forbidden thousands of West Virginians to drink or use any
water. As a result, many have been forced to drink and wash with bottled water.
However, even as the chemical has been diluted enough to be considered safe to
drink, many West Virginians still will not drink the water. Their reasons
primarily include fears of damage to the liver or kidneys, and interference
with human metabolisms. Hopefully with time, the water will be able to dissolve
the chemicals into small enough pieces where the chemicals will have no effect
on humans.

Bracing for Carp in Great Lakes, but Debating Their Presence
According to the Army Corps of Engineers, remnants of environmental
DNA of the Asian carp have been discovered to have arrived in the Great Lakes.
Environmental DNA, or eDNA, is genetic material that is not directly from the
fish, but from shedding of scales, gills, or waste products found from birds
who have consumed this fish. This invasive species was first introduced from
China to clean up algae-ridden fishponds in the Arkansas River in 1976. Since
then, the carp has moved up the Mississippi River towards the Great Lakes. If
these fish make it to the lakes, it can cause large problems. The carp
reproduces very quickly and can eat as much as 10 percent of its own weight in
a day. Thus, these fish can lead to the possibility of wiping out entire ecosystems.
Therefore, environmentalists must act quickly before this non-native species
eliminates the entire region.
