anaged Aquifer Recharge (MAR) is becoming an increasingly important strategy for water
resource managers, providing for the ability to store water in aquifers during times of
plenty and then mine the stored water when the need arises. This approach provides
great flexibility for water resource managers in solving today's complex water problems.
However, using MAR in aquifers can provide other benefits that are often overlooked. One of these is
the ability of aquifers to provide a degree of water treatment. In Florida, considerable attention is being
placed on the environmental impacts to surface water bodies from excessive nutrients like phosphorus
and nitrogen present in stormwater or wastewater.

Natural treatment systems for wastewater
have been the object of study and research
for many years (Kruzic 1997). These systems
are quite varied and include soil-based,
wetland, and aquatic systems. Today, other
types of degraded water are also being

increasingly treated using these treatment
systems (e.g. stormwater). Managed aquifer
recharge systems fall into the soil-based
treatment category and can include surface
spreading systems or injection well systems
like aquifer storage and recovery (ASR)

projects. In both types, water treatment or
soil aquifer treatment (SAT) is accomplished
via a number of important mechanisms
(Liehr 2005) including:
* Physical straining;
* Chemical changes; and
