While spills and
other accidents do happen at industrial plant sites, much of the contamination
that accrues through time at manufacturing, refining, and other sorts
of industrial operations happens as the result of daily operations - the
expected and intended result of product storage, product transfers from
rail cars, trucks, drums and other containers into and out of process
areas, and on-site disposal practices. Information from historic aerial
photographs, maps and other supportive data sources can be central to
understanding what materials are present and what processes were used
through time, and where at a site. |
