microorganisms able to degrade hydrocarbons. Monitoring of dissolved TPH in
groundwater during the tears 2003-2010 demonstrated a relatively stable plume that
neither shrank nor expanded. The low rate of natural attenuation and the fact that the
contamination in the centerline of the plume does not decrease with time suggest that
such changes in groundwater chemistry are irreversible on a human lifetime scale.
The above examples show that despite the decrease in the initial contaminant
mass due to a natural attenuation, a fraction of the petroleum hydrocarbon pres-
ence remains ''irreversible,'' affecting groundwater chemistry.
