font-family:"Maiandra GD"'> The influx of excessive amounts of nitrogen from
anthropogenic sources, including wastewater from residential septic systems, is
greatly responsible for water quality degradation and habitat loss in our
coastal waters. Eutrophication, excessive algal and plant growth in the water
due to this over-abundant nutrient stimulation, reduces dissolved oxygen,
clouds the water thus severely limiting light penetration, kills other
organisms, degrades the aesthetic qualities of coastal waters, threatens
recreational uses of waterways, and may severely hamper the commercial harvest
of fin fish and shellfish. Thus, developing low-cost, efficient technologies
that significantly reduce nitrogen loads from wastewater and other sources are
very important to the health and sustainability of coastal waters.<br>
<br>
At present, several types of onsite denitrification are in common use, but many
questions remain about the cost and effectiveness of the first generation of
technologies. This workshop will examine three new technologies in development
that strive to markedly increase the amount of nitrogen removed from wastewater
or groundwater. Following an overview of current on-site denitrification
systems, the new systems (an innovative biological process, barrier
interception, and leach field aeration) will be described and analyzed by the
researchers working on them; followed by a workshop wide discussion of the
technologies, and their policy and land use management implications. <br>
