I believe that if one is tagging an area to imply that there is
contamination, one should cite an authoritative source. Having your
property tagged as potentially contaminated could lead to difficulties
in selling or refinancing the property. Even if a property was
contaminated, it could be remediated to the point where no
contamination exists on the site anymore. If the tags are not
maintained, they will likely be inaccurate.
In the US, when a person/corporation has a major financial or
ownership transaction related to a property, there is often a review
of the current and historical activities that have taken place on and
in the vicinity of the property. (A Phase I Environmental
Assessment). The result of this is a list of potential environmental
risks or hazards.
I would suggest keeping information about contamination out of OSM and
leave it up to the end user to mash OSM data with up-to-date data from
the local environmental authority. If one has knowledge about current
(and maybe past) land use activities, they could tag that. This in
turn could be a good source for people who are doing environmental
Think about the weight of tagging a property as contaminated.
Incorrectly tag a property as a pub and you might get some frustrated
people parked in front of the house on a Saturday night. Incorrectly
tag a property as contaminated and you may delay an important
transaction or force a person to spend money to prove that their
property isn't contaminated.
