What you should know

It is unlawful to test drinking water without certification. Recently, companies, including prominent big-box retailers, have offered "free" testing in exchange for a sales pitch for expensive and often unnecessary treatment systems. Remember to have your water tested by an independent, certified laboratory before making any decision about treatment. Only a certified testing laboratory can provide an objective analysis of your drinking water.
