Interpretation Acid-mine drainage occurs when sulfide-bearing waste rock and tailings come in contact with waters containing dissolved oxygen. The resulting oxidation reactions release associated metals and acidity, which may impact the biological community and significantly lower the pH of downstream waterways (Army, 2010). Released metals that are transported downstream may be removed from solution through precipitation of and sorption onto iron and manganese hydroxides. Attenuation of metals…

Each dog was up to date on treatments for heartworms, fleas, etc. It was…

very safe and patients can be instructed to self treat to manage their conditions independently. Cryotherapy is most commonly used in sports and acute injury treatment and is cheap and simple to use.
