What is a brownfield?

The Environmental Protection Agency (EPA) defines a brownfield as “real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant”.

How many brownfields are there?

EPA estimates there are more than 450,000 brownfields in the US.

Brownfields are often abandoned, closed or under-used industrial or commercial facilities, such as an abandoned factory in a town’s former industrial section or a closed commercial building or warehouse in a suburban setting. Brownfields, however, can be located anywhere and can be quite small.

Unfortunately, this map is not a complete list of all New York City brownfields; NYC houses over 7,000 contaminated sites. As of now, no complete list is available to the public. There is major room for improvement in raising community awareness on brownfields.

    May I suggest you look into brownfields remediation – there are lots of DIY tactics as well as expensive solutions by environmental engineers, using effective microorganisms. I have a great friend working on such a project in troy NY I can connect you with And there’s RADIX in Albany – led by Scott Kellogg, whom I learned a lot from!
