Bringing heavily
contaminated brownfields back into productive use is many times not
simply a financial or regulatory issue, but one often involving difficult
technical tasks. Any site where there has been previous industrial
uses is likely to suffer from contamination by a variety of substances
(see chemcicals section). Designing robust and sustainable methods
of remediating sites is a key task of engineering. This entails developing
high-quality methods of risk analysis and conceptualising the extent
of the contamination (see SUBR:IM Project G and also the American
Environmental Protection Agency's document on this here.
Many brownfield
sites require extensive restorative treatments before they can be
development for future uses. For example, acid tar lagoons are particularly
challenging from a technical perspective as at exposed surfaces, the
tar weathers into different forms, depending on temperature, moisture
and other conditions. As geological, topographical, and environmental
conditions differ from site to site, each site may present a specific
environmental impact problem. More information on acid tar lagoons
can be accessed here.
Engineering
is also important for the protection of human populations and valuable
resources, such as water, which can be contaminated by heavily polluted
brownfield sites. More information on this can be found on the Eugris
website.
