lol there are signs on the Allegheny in Kittanning that read: “Warning, do not swim downstream of this sign, RAW SEWAGE DISCHARGE”
also, almost bought a house in Templeton a while back… one of the guy’s key selling points was “yep, no sewage bill, no septic tanks to worry about. It all goes right into the river!”
Don’t get me wrong, I grew up swimming in it and it doesn’t really bother me, but those rivers are pretty nasty.
