Water as well know is important to life. Without it, no living species on the planet would thrive except maybe for bacteria. In today’s fragile ecological environment, it is imperative that we are able to save as much of our finite fresh water sources and save those that we have already contaminated. In order to understand the groundwater treatment system options available, we must learn how different pollutants affect water quality so as to better understand the entire process.
Harmful bacteria may be eliminated from groundwater by ensuring the water remains underground at least 30 days before being used by either animals or human. This option is quite effective particularly for E. coli as well as a host of viruses. Bacteria like staph and Giardia may be destroyed through chlorination or by some other chemical treatment of the water. Proper treatment needs to be done at all times as Giardia is known to survive even for an hour after chlorination is instituted.
These pose one of the biggest challenges for remediating groundwater as these can come from a variety of sources such as runoff from agricultural land, waste from factories and even chemicals right off our kitchen sinks and bathrooms. Volatile organic chemicals pose the greatest danger and an array of treatment methods are available to specifically address this problem. Air stripping is one such method used to treat this problem effectively. Other kinds of chemical processes also affect water quality and produce a heavy impact on the environment. Overuse of fertilizers and pesticides as well as acid waters from mining drainage are prime examples.
Examples include sediment and heat are mostly released from a point source. The fact that sediment naturally settles to the bottom of a still body of water, this kind of pollution may be removed from water by using a stilling pond prior to release to a waterway. Heated water on the other hand can simply be allowed to cool naturally.
