Contamination and Pollution

Here are some USGS resources on acid mine drainage:USGS Energy Resources Program - Environmental Effects
As a government agency, the USGS does not comment on commercial products, but many organizations evaluate consumer products and post product reports on the Internet.
The EPA Ground Water and Drinking Water section keeps a table of regulated drinking water contaminants and their potential health effects from
The Federal Emergency Management Agency (FEMA) and the American Red Cross have put together a booklet titled "Food and Water in an Emergency" which includes a section on ways to treat water.
USGS scientists have discovered that the atmosphere is a potential source of the low concentrations of methyl tert-butyl ether (MTBE) detected in shallow ground
Yes, but in small amounts. In addition to USGS studies of ambient groundwater, USGS is conducting focused studies to assess MTBE concentrations associated with drinking-water supplies.
NAWQA findings indicate that MTBE is most frequently detected in ground water underlying urban areas in comparison to agricultural and mixed land-use settings. MTBE was detected in about 14 percent of wells sampled in urban areas.
The answer is yes. The environmental effects of acid rain include the acidification of lakes and streams, damage to trees at high altitude, the acceleration of decay in buildings, and poorer air quality.
No, but it can cause problems. Depending on where you live, maybe you've heard of acid rain.
