industrial areas and from agricultural land and mining operations makes its way back to receiving waters (river‚ lake or ocean) and into the ground. STORMWATER Stormwater is a point source that contributes to water pollution. Because impervious surfaces (parking lots‚ roads‚ buildings‚ compacted soil) do not allow rain to infiltrate into the ground‚ more runoff is generated than in the undeveloped condition. This additional runoff can erode watercourses (streams and rivers) as well as cause flooding

dumped into exploration holes dug out to map mining areas. After the mining had stopped in the 1960’s‚ the mines flooded and these waste materials began to mix in with the rest of the water that filled the mine. Eventually‚ this water reached the surface and formed springs of contaminated water. “Highly contaminated acid mine water began flowing from the mine shafts in Ottawa County Oklahoma in 1979‚ just as predicted by the miners during the 1950’s and in 1977 by S.J. Playton of the USGS. This

Hydrogen peroxide‚ size of Potato‚ concentration of Hydrogen Peroxide Hypothesis I predict that the breakdown of Hydrogen Peroxide will be quicker when the surface area is increased. If you cut the same size piece of potato into smaller pieces‚ I believe‚ the breakdown will be faster. I predict that an increase in surface area will result in an increase in kinetic energy. Since the size of the area increases‚ I think that more oxygen will be released from the Hydrogen Peroxide and

POLLUTIONS Environmental issues become one of the top topics nowadays. Environmental issues like pollution‚ climate change‚ global warning and deforestation are being discussed this day. Pollution is one of biggest concern in the environmental issues because it covers all which are water pollution‚ air pollution‚ soil pollution and noise pollution. Pollution is contaminants that can cause an adverse change s to environment and human health. Pollutants is components of pollution where it can be foreign

important that the main water supply to the fishpond be safe and free from contamination. Contaminated water is the main cause of death in fish grown in fishponds. Keep the fishpond away from waste water drainage systems and away from routes of running surface water. In regards to the topography of the site‚ it is important that the fishpond is situated in a location that is properly inclined to allow effective and efficient inflow and outflow of water in the fishpond. It is advisable that a fishpond is

The Consequences of Water Pollution Annually‚ 90 million people add to the current population of 6.5 billion. At this rate the global population will reach approximately 8.5 billion by 2025 (http://dieoff.org/page120.htm). As the global population grows exponentially‚ so does the demand for natural resources. Of all these natural resources‚ water‚ is the most vital for survival and expansion. Human’s dependency on water will never go away‚ making it a key part to any civilizations future. It
