Fecal matter on its own is a nuisance but not much of a health hazard because for the most part it is stationary and you usually don’t find it out in the open where it can cause widespread contamination. That is to say, yes tent homeless go #2 but usually go into the brush, woods, or other areas that provide concealment for them to do their business. As a result, the fecal matter lands in a single place, most often in dirt or grass where other organisms immediately get to work in breaking it down and it remains there by and large. The contamination is localized. This is not the same as raw sewage. It’s human waste and there is a difference.
Sewage = human waste +fluid, typically water and or urine. This is what really takes the smell from 3 to 20 and worse, makes the bacteria, pathogens and other harmful contaminants within transient. RVs typically park on pavement. And so dumping their tanks on pavement means there is a greater public health hazard because now not only are those contaminants highly transient, but they are being absorbed into the ground much more slowly since they are on pavement and there are far fewer organisms available on that surface to begin the decomposition process.
that’s why you target RVs - they are the real health hazard when it comes to this. I don’t know about you, but I’ll take a mountain of poo over a river of sewage any day of the week.
