What’s in your water?

What’s in your water, and how did it get there? Clean water is a must, but modern living can put a lot of bad stuff in it. Road salt, fertilizer, dog doo-doo, heavy metals – how do these things get in our water? Why should we care? And how can we tell if our water is healthy?  Check out this episode!

The wonderful weirdness of water

One of the weirdest substances in the universe is right under your nose. No, not boogers. Water! Water seems ordinary, almost boring, but take a closer look and you’ll find a wonderfully weird molecule that behaves like nothing else in the universe. Why is water so weird, and why does that matter? Listen to find out!  Check out this episode!

Burning Rivers of Fire

Rivers are known for being wet. So how did a river in Ohio suddenly catch fire, not once, but several times last century? In part three of our water series, we’ll explore the shocking tale of the Cuyahoga River. We’ll look at how pollution led to this environmental tragedy and what’s been done to address the problem. Check out this episode!

Keeping water healthy, one clue at a time

In the previous podcast, we heard about the tale of the Cuyahoga River — a river in Ohio that caught on fire multiple times because it was so polluted. The river is now doing much better, but beyond the fact that it’s not on currently fire — how do we actually know it’s healthier today? That’s when being a water detective really comes in handy. Check out this episode!
