WORK TASKS COMPLETED
FOR YEAR 2001
Groundwater Level
Monitoring Program for
Back Bay, Fenway,
South End, Beacon Hill and Chinatown Areas of Boston
- Measurement and Recording
of Groundwater Elevations: Continued to measure all operable observation
wells about three times per semester (approximately 9 readings per year).
Continued to update database with new data from these readings, data
generally entered within one week of the readings. Using the data from
the well readings, developed study area plans to summarize potential
"problem" areas where groundwater levels were measured to
be below Elev. +6 BCB; updated as each
new set of groundwater level data was entered into the data base.
- Prepared Proper Documentation
for Application to Install New Wells: Completed permit applications
for the installation of 35 new observation wells in the Fenway and Back
Bay areas. Worked to complete these permit submittals in a manner to
address PIC concerns. Applicationincluded AutoCAD drawings for each
well location showing known utilities (water and sewer).Funding for
this capital expense is planned from the two $25,000 linkage grants
received by the Trust
($50,000 total).
- Building Permits Search
at Inspectional Services: Research building jackets at ISD to determine
areas of wood pile foundations at the perimeter of the principal study
area, and which will also be included in further study of groundwater
levels.
- BRA: Contact BRA upon
receipt of all Project Notification filings to insure that groundwater
wells are included
in construction documents.
- Base Plans: Continued
to work on the plans, to make sure that all wells are shown in correct
locations. Contacted BWSC and BRA to obtain updated databases, as
may be available, to correct building locations, however, there is no
update available as of yet.
- Collection of Groundwater
Level Data from Public and Private Parties: Updated database with
new well data that was obtained from various developers, building owners
and city agencies that had previously been agreed to being in the program.
Expanded the database to allow including groundwater level data from
previous years, prior to the commencement of the present program.
- Locating Additional Existing
Observation Wells: Continued to search for other existing observation
wells, which either were not identified in the 1990 report by Stone
& Webster, or have been recently installed. Determined ground surface
elevations at each new well by surveying from known benchmarks. Some
of these wells were located based on additional information provided
by other parties (from No. 6 above).
- Website Development:
Worked with the web designer to launch an interactive base plan on
the website. Provided BCB elevations of groundwater levels in wells,
that are posted on the web for each set of readings. Continued to post
news articles to website.
WORK TASKS FOR CO-OP
STUDENTS
Groundwater Level Monitoring
Program for Back Bay, Fenway, South End, Beacon Hill and Chinatown Areas
of Boston
- Measurement of Groundwater
Elevations: Continue to measure all operable observation
wells at three to four times per semester. Continue to update database
with new data from these readings, within one week of the readings.
Develop study area plans
on CAD to summarize "problem" areas with groundwater levels
below Elev. +6 and +5
BCB, for each set of new groundwater elevations as they are gathered.
- Monitor the Installation
of New Observation Wells: During the installation of new observation
wells in the Fenway/Symphony and Back Bay areas, monitor the drilling
contractor’s installation of new wells and document details of
each installation in
the database.
- Building Permits Search
at Inspectional Services: Continue to research files/permit jackets
as ISD to determine areas of wood pile foundations, the elevations of
tops of wood piles and where wood pile repairs have been made. This
data helps to identify
portions of the study area where different "critical groundwater
levels" may be established.
- Base Plans: Continue
work on the plans to make sure that all wells are properly located.
Obtain updated databases from BWSC (or BRA) as available to correct
building locations.
- Collection of Groundwater
Level Data from Public and Private Parties: Update database with
new groundwater level data from the wells (data that is provided by
various developers, building owners and city agencies). Add to an expanding
database as necessary to allow including groundwater level data fromprevious
years.
- Locating Additional Existing
Observation Wells: Continue to search for other existing
observation wells, and incorporate those found into the program. Determine
ground surface elevations by level surveying for newly found wells.
