Dealing effectively with hydrogen sulfide (H2S) in groundwater presented a major challenge for coastal Indian River County, Fla. Stripping the odorous substance from the water was only half the solution; keeping the smell from drifting through the air in the neighborhood was the other half.
Like most central
Florida communities, Indian River relies on deep wells to withdraw water from
the Floridan aquifer. The inland supplies are fresh water, and the coastal resource
is typically high in total dissolved solids (TDS) and chlorides. Both the fresh
and saline water supplies contain high concentrations of H2S.
