Memorial Day weekend is the unofficial, official start to summer. Many west Texans will spend this weekend out on Big Country lakes. But have you ever thought about what's in the water?

We spent time testing the water chemistry of Lake Fort Phantom and Lake Kirby, two lakes that are popular destinations every year.

We are testing the water using Simple Water Tap Score. They are a California-based company that specializes in testing tap water. However, they are also capable of testing lake water, too.
