Surface Water Fixed Site Monitoring
|
Monthly monitoring of the following
sites for field parameters, nutrients, major ions and suspended
sediments:
- 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
EMPACT study)
- Saugus River at Saugus Ironworks (supporting Saugus Iron Works
National Historic Site activities) |
|
Trace Elements in Surface Waters Attached to Suspended
Sediments
|
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. |
| Nutrient/Chlorophyll
Synoptic |
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
reaches. |
| 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. |
| Water-Quality of
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. |
| Determination of
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. |
