[SEMCO] Denitrification System Technologies Workshop

[Tompkins, Laurie (DCR)]

New Technologies and Alternatives to Traditional Septic Systems 
March 15, 2005
8:30am -- 12:30pm
Waquoit Bay Reserve Visitors Center
 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.

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.
