I’ve got a question there is a wastewater treatment lagoon that hasn’t been operated since 2003 and the water is pretty clear is the water fine to swim in when the place hasn’t been used in 18 years
Probably not. There are typically a lot of heavy metals in sewage. Which will always be there. Plus a lot of other things get flushed into lagoons. Eg needles, tampon applicators, medication. The biological processes will have cleaned the water a lot over that time but it would be the sludge that would be quite dangerous.
