Dear Liaison Committee Member:
I hope this letter finds you well and having a good Spring. You
are invited to attend the next Liaison Committee meeting of the
New England Coastal Basins (NECB) National Water-Quality Assessment
(NAWQA) Program Study scheduled for Wednesday, May 16, 2001. We
will update you on study activities, results, and future plans.
This meeting, which will begin at 9:30 am and conclude by 3:00 pm,
will be held at the Westford Regency Inn, Westford Massachusetts
(directions are presented below). An agenda and registration form
for the meeting are enclosed.
We have published a new report titled Shallow Ground-Water Quality
in the Boston, Massachusetts Metropolitan Area that describes
the results of our 1999 monitoring of shallow ground waters in newly
urbanized lands of the Boston area. Copies of the report (and previous
NECB study reports) will be available at the Liaison meeting; if
you can not attend the meeting but would like a copy of the report,
please fill out the enclosed meeting registration form.
The year 2000 was our most intensive field data collection year
and was the second of three active field data collection years for
the study. We sampled nearly 60 domestic bedrock wells in Maine,
Massachusetts, and New Hampshire, and did some specialized monitoring
of two bedrock wells in coastal New Hampshire to address arsenic
occurrence. We completed the second and final year of routine monitoring
at our 10 fixed surface-water sites. All sites were monitored for
nutrients and suspended sediments; in addition, two sites, the Aberjona
and Charles Rivers, were seasonally monitored for volatile organic
compounds. Our most extensive field effort last year was the urban
land use gradient study that monitored 32 streams from Connecticut
northward to Maine. These streams represent a gradient of urbanization
from less than 1 percent urban land in the watershed to nearly 70
percent urban land. At all of the gradient study sites we monitored
nutrients and pesticides, periphyton biomass and species, macroinvertebrate
and fish communities, physical habitat features, and continuous
stream stage. Finally, we worked with other NAWQA Program staff
to conduct lake coring work at 9 lakes in the study area; 7 of these
lakes were in the Boston area and 2 lakes in the While Mountains.
The purpose of the coring work is to be determine long-term trends
(50+ years) for trace metals, semi-volatile organics, and pesticides.
Our studies and field data collection plans for 2001 are described
in the enclosed table.
We hope that you remain interested in our NAWQA study, and we welcome
your input on any of our activities. If you are planning to attend
the meeting, please return the enclosed registration form by
May 9 in the self-addressed envelope provided. If you can not
attend the meeting, but would like to discuss any of the NECB study
activities; or if you have any questions regarding the meeting please
give me a call at 603-226-7809 or e-mail me at email@example.com.
We appreciate your interest in the NECB NAWQA study and look forward
to seeing you next month.

New England Coastal Basins NAWQA Study
