Mine drainage refers to any surface water or groundwater that drains from an active or abandoned mining operation. Mine drainage can be high-quality similar to natural waters or contaminated by leftover materials. Polluted mine drainage can be extremely acidic and is often laden with high concentrations of toxic, heavy metals. In general, the more acidic the water, the more likely it is to be harmful to living organisms.
There are 42 species of snakes in South Carolina and Georgia and only 6 of them are venomous. The venomous species that we do have tend to be quite secretive and are some of the least frequently encountered species. The most frequently observed of our resident snakes are black racers, rat snakes, and nonvenomous water snakes, common and important predators in our ecosystems.
Besides “air,” which is made up of primarily/approximately 78% nitrogen and 21% oxygen, there are four main gases that concern workers in a coal mine. They are carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), and hydrogen sulfide (H2S).
Surge piles of mined material at coal mines have inherent hazards for personnel and equipment working on or around them.
Summer severe (convective) weather presents many challenges to the forecaster. This self-paced, distance learning course addresses the scientific aspects of a few of those challenges: buoyancy, shear, and their interaction to create various types of summer severe weather phenomena (squall lines, bow echoes, supercells, etc).
