Rain Garden Research & Results
The negative impact of urban areas on water quality is a well-documented
phenomenon. Rain gardens,
or bioretention areas, were
developed in Prince
George's County, Maryland as part of Low Impact Development
(LID) to reduce nonpoint source pollution.
The paired rain gardens located at the Haddam demonstration site
were sized to contain one inch of roof runoff. Monitoring for flow
and pollutants was performed by Michael
Dietz and John
Clausen in the Department of Natural Resources Management and
Engineering at the University of Connecticut, from November 2002
through December 2004. Monitoring has ceased, but the gardens continue
to be used as part of the sustainable landscape demonstration site
through the NEMO program.
