The Federal Emergency Management Agency (FEMA) lists several ways to purify water for human consumption on their Community and Family Preparedness Web page. Also, the EPA fact sheet Emergency disinfection of drinking water is available in English and...
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 water in southern New Jersey. The scientists measured atmospheric concentrations of MTBE from...
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. In cooperation with EPA's Office of Ground Water and Drinking Water,...
  MTBE was the third most  frequently detected VOC in aquifers. MTBE was the third most frequently detected VOC in aquifers. MTBE findings demonstrate how quickly some anthropogenic chemicals, especially those that are mobile and persistent like MTBE,...
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. In addition, incidence...
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. The USGS studies these and other effects of acid...
No, but it can cause problems. Depending on where you live, maybe you've heard of acid rain. Now, acid rain is not pure acid falling from the sky, but rather it is rainfall or atmospheric moisture that reacts with air pollutants (primarily sulfur oxides...
Acid precipitation affects stone primarily in two ways: dissolution and alteration. When sulfurous, sulfuric, and nitric acids in polluted air react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and...
Scientists from many disciplines are studying acid precipitation and its impact. The National Acid Precipitation Assessment Program, a Federal program involving representatives from more than a dozen Federal agencies, has sponsored studies on how acid...
First of all, plants naturally grow in and around lakes. Maybe you're asking about a lake that is being choked off by too much algae. In many cases, humans are responsible. Actually, these lakes are being fed too much food for plants! There are certain...
