In '78 I worked as a general dogsbody doing water quality analysis around the river forth estuary. Suspended solids, phosphate & nitrates from fertiliser factories and manufacturing alongside sewage outfalls were measured right upstream, to tidal limits and from the top north shore to the south. 100km or more. My constant tl;dr is that stuff moves, and whilst nothing like the tidal zone, groundwater is anything but static. My case? Estuarine. The Biscayne aquifer is limestone. Highly porous. Water will travel as water does. If anything even close has contamination its getting in, if there's transport from surface water into the aquifer. The stuff here says urban canals and groundwater flows definitely feed in. Any firestation testing foam? Its in. PFAS contamination from airport fire testing is a thing. https://www.evergladesfoundation.org/post/water-on-earth-explaining-the-wonders-of-the-biscayne-aquifer https://www.evergladesfoundation.org/post/water-on-earth-exp...
