Heck, back then we even SWAM in the lakes and ponds!

Nope, never got sick and to be honest, back in those days we never even thought about things like pollution of any sort. The "uniform of the day" was shorts ... that's it, no shirt, no shoes ... just shorts. We'd ride bikes, play ball, hike, whatever ... then jump in the nearest lake to cool off when needed. Heck, lakes are never more that 5 minutes apart down here. As kids, we'd just splash water at the gators if they got too close! (I'm older and wiser now and prefer the pool these days)
