Whats in your water?

When it comes to finding out what contaminants may be in your home's drinking water, a good place to start is by contacting your county's Health or Environmental department—especially for rural and well water users. These departments can provide you with information you may need to know about area water contaminants.
Another good source of information is your municipality's water provider or utility. Municipal water utilities are required by the Environmental Protection Agency (EPA) to rigorously test their water regularly and to make the test results available publicly and report the results to the EPA.
You can also visit the EPA online for an overview of water conditions in your area by visiting http://www.epa.gov/safewater/dwinfo/index.html. Then, once you have an idea what's actually in your water, it will be easier to choose the water filtration system that's best suited to your needs.
