Pinatubo erupted, in the Philippines, it released more pollution IN ONE DAY, than man has released in 200,000 years.

According to news today, the company has suspended the use of these chemicals. http://www.portlandmercury.com/BlogtownPDX/archive...As far as affecting home values, I think it's probably good news that chemicals are from an active point source (which can cease polluting) rather than arsenic or cadmium leftover from industry or natural to the area.

A UV light will need to have the bulb changed probably every year.One investor that I know claims that a disgruntled tenant continually ran the water to saturate the septic and drain field, causing him to spend $25,000 for a new system, immediate afterwards he sold the property.Shallow dug wells are susceptable to all kind of pollution including fertilizer, chemical and natural, septic systems, insects and even a decaying animal.

In Texas for example there are restrictions that there can be no more than 7 homes per acre as a means to ensure that septic will not cause pollution (some counties restrict one septic per acre, but you can get around this with a larger commercial system for multiple homes...).  

They have polluted your pool of buyer's. 

Laws were passed by good ol Bill White to cut down on street pollution and even set up a bandit sign enforcement team that WILL come looking for you.

We haven't been able to find a solution to that problem and it's likely caused but global warming and pollution so it's difficult to see a solution anytime soon.

It "oxidizes" the pollutants leaving you with fresh O2 to breathe and no smells!

It seems that municipal garbage services would be intrusive big government at its worst; the thin end of a socialist wedge that would deprive the citizens of their right to choose which noisy truck lumbered up to their house on a weekly basis ;These trucks get 2 mpgA single hauler need 5 trucks full time to replace 35 independent haulersThese are the biggest and heaviest trucks in neighborhoodsProbably there are 10 garbage trip per week on any given street versus 1These mom and pop trucks are the dirtiest polluters Garbage goes out on your block just one day a week.

My suspicion is they go under contract with a bid above asking price, and then during the close process, the buyers realize that they have to make up the difference in appraised value and can't.I currently have friends looking in the Globeville area (despite the I-70 expansion proposal and the pollution)...they've made multiple offers they've lost out on for the same reason you have.
