Recently pervious
concrete, "no-fines concrete" or "porous concrete" has been
developed to help with the problems of storm water runoff. It is
being used all around the country and it can be used for many
surfaces such as parking lots. The water is allowed to percolate
through the concrete into the ground instead of washing off so
that runoff and its potential for downstream pollution is
reduced.
One concern that people have is that pervious
concrete may allow oils and other hydrocarbons to percolate
through to the ground water underneath, but preliminary studies
have indicated that the pervious concrete may partially trap
them and still allow water to percolate through. This
competition is designed to explore the variation in hydrocarbon
trapping capacity in pervious concrete.
