Water Contamination Information

This weeks blog is going to describe how to navigate through a web site to find information about certain water contamination facts.  We will start at the site http://www.odh.ohio.gov/ , and once here, we will click on the W listed in the A-Z index.  Then, we will click on water quality, where a list of contaminants in the water will come up.  Let's choose one, say selenium.  So, we will click on selenium on the site http://www.odh.ohio.gov/odhprograms/eh/water/PrivateWaterSystems/quality.aspx , to obtain further information about selenium contaminating water.  Once you click on selenium, you are redirected to another site.  This site is http://water.epa.gov/drink/contaminants/basicinformation/selenium.cfm , and there is a lot of information on the page.  There are paragraphs with bold questions titling each paragraph about what each individual paragraph is going to be about.  Examples are, what is selenium, uses for selenium, EPA regulations for selenium in drinking water, and selenium health effects.  So, what is selenium?  Well according to that site, it is a metal that can be found in natural deposits.  An example of a natural deposit would be an ore.  On this page you can also find other EPA levels and regulations on drinking water as well as how selenium can get into drinking water.  Basic facts about drinking water can also be found on different tabs and links all through out this page, and there is also a tab towards the right of the screen that contains the maximum contamination level of selenium and the maximum contamination goal level of selenium.  Again, we are just using selenium as an example, there is a whole list of contaminants that can be researched and studied that will also have these sort of facts on this site as well.  I hope this blog was helpful in providing information about how to navigate this site to obtain the desired information about drinking water.
