I probably notice it more because I am sensitive to a lot of chemicals that don't seem to bother most people. The chemical solution that is commonly used in tanks contains formaldehyde. It is bad to breath, and bad for your tanks. In a few parks I smelled it pretty strong, and in others it isn't as bad. Some parks have a rule not to use those chemicals, but people do anyway. My guess is a lot of people just don't think much about it because they don't have allergies to the chemicals.
If you are smelling chemicals you are most likely parked close to a chemical porta pottie or bath house that uses one. I make a point of not parking near these.
Once chemicals are put into an RV holding tank and MIXED with sewerage waste you can not smell the chemical. All you smell is the sewage. No chems used and the smell of the waste coming out quadruples.
