The likely hood is that based on the age of the community the cottagers are polluting the lake, E.coli counts are probably up in the swimming area during the summer after a rain and at some point it will be discovered.

Most of that electricity previously came from the heavily polluting, coal-fired Navajo Generating Station which created a lot of problems for the Navajo Nation and was just destroyed a few days ago actually.

Some countries like China have to think about how much to pollute killing people that way vs starving people to death every day. 

Lots of traffic and pollution.

Whole foods  Safeway and our local high end store Zupans all within 3 miles of me and since I am going in the Tesla I am not polluting either LOLmiddle road is those clubs that send you meals .. that you simply cook I tried that.. but I don't like others picking out my veggies etc.. or touching them .. and they wrap everything so it takes a bunch of time to unwrap one radish that is in plastic waste of energy and not very environmentally friendly.. 

The local governments seem to be pretty averse to anything manufacturing or "polluting".  

The oil is pollution and seeps into the soil, possibly the groundwater. 

Or, is someone just tired of the signs, which are illegal in some communities, may be illegal without first paying for a permit, or simply considered a nuisance by someone living or working in the area and you are polluting their neighborhood in their mind?

Pollution dropped, outside litter reduces, plastic bag reduction etc.

If you buy a polluted property, it's highly likely that the cost of cleanup is yours.I've represented a few gas stations in Massachusetts, so from experience I can tell you that you'll need a current environmental survey.
