These scientists are keeping an eye on which KC beaches are safe for swimming

Memorial Day is a time to honor America’s fallen soldiers past and present. It’s also the unofficial start of summer. Today’s weather isn't exactly ideal for a beach swim. But once we get to magical Seattle summer weather, don’t forget to check King County Public Health’s website before you take a dip. They send out environmental scientists like Wyatt Klepac each week to test our swim beaches for toxic algae and bacteria. Right now, Green Lake’s West Beach is closed because of toxic algae and Newcastle Beach due to high bacteria. Last summer, we were curious about how the county decides to close beaches and went out with Wyatt to see for ourselves. Here’s that episode again.
