MANUFACTURED GAS PLANTS --
Manufactured Gas Plants, 2010 (Source scale is unknown)
MGPs produced gas for lighting, heating, and cooking from the 1850ís to
the 1940ís. In addition to producing the desired product, gas, numerous toxic
by-products (such as tars and purifier wastes) were often stored in subsurface
structures or disposed of in the dump areas at the site. Significant amounts of
contamination usually occurred at these sites due to the nature of gas production and
poor housekeeping. MGPs productions decreased and were phased out in the 1940ís due
to the increase network of natural gas pipelines across the country. These plants
were decommissioned by razing the building but leaving subsurface structures and wastes
in place. There are at least 74 known former MGPs in Indiana.
