Surface Water Fixed Site Monitoring
|Monthly monitoring of the following
sites for field parameters, nutrients, major ions and suspended
- Aberjona River at Winchester (NAWQA Trends site)
- Charles River at Watertown (NAWQA Trends site)
- Merrimack River at Lowell (NAWQA Trends site)
- Stillwater River near Sterling, MA (NAWQA Trends site)
- Ipswich River near South Middleton (supporting Parker/Ipswich
- Saugus River at Saugus Ironworks (supporting Saugus Iron Works
National Historic Site activities)
Trace Elements in Surface Waters Attached to Suspended
|Storm sampling of 4 rivers upstream
of where lake coring was performed in 2000 to determine the origin
of trace elements in the cores. The Charles, Aberjona, and Mill
Rivers will be monitored during 4 storm events in the Spring and
Summer; Big Round Top Pond (RI) tributaries will be monitored once.
|Sources of VOCs to
an Urban Stream
||A short-term synoptic of the Aberjona
River in the Spring will be performed to determine the sources of
VOCs to this urban stream.
||Nutrients and chlorophyll levels will
be monitored over the course of the Summer at about 10 streams;
most of these streams were part of the urban land use gradient study
done in 2000. Open and closed canopy areas of the stream will be
monitored. Streams will reflect a combination of impaired and un-impaired
|Water Resource of
the Saugus River at the Saugus Ironworks National Historic Site
||The NECB NAWQA study is collaborating
with Saugus Ironworks National Historic Site to characterize the
current and historic water quality and quantity of the Saugus River
for park interpretative displays.
Stratified Drift Aquifers in the NECB Study Area
||Thirty public water supply wells that
tap stratified drift aquifers will be monitored for a host of chemical
constituents and radionuclides.
Arsenic in Ground Water, Bed Sediments, and Rocks in the New England
||NECB NAWQA scientists will continue
collaborating with the USGS Geologic Division to identify regional
patterns and relations of arsenic in ground water, bed sediments,
and rocks of New England.
