WELL MONITORING

The BGwT’s latest set of readings are indicated below.
Wells were read from Jun. 11th - 30th, 2010

There are currently 720 wells in the West network. Of the 720 wells read:

• 46 wells @ elevation >9’
• 122 wells @ elevation 7’-9’
• 310 wells @ elevation 5’-7’
• 186 wells @ elevation 3’-5’
• 29 wells @ elevation <3’
• 0 wells @ Dry
• 27 wells @ no reading
• 94 Recharge Locations

We have read 85 wells in the East network (East Boston Area). Wells were read in East Boston on Jun. 7th & 9th, 2010. Of the 85 wells read:

• 27 wells @ elevation >9’
• 24 wells @ elevation 7’-9’
• 12 wells @ elevation 5’-7’
• 5 wells @ elevation 3’-5’
• 11 wells @ elevation <3’
• 4 wells @ Dry
• 2 wells @ no reading

NOTE: We are continuously reading the well network and started a new set of readings on Monday July 5th, 2010 with our returning part-timer Robert Tully from Wentworth Institute of Technology.
Robert has continued to work out extremely well for us so we have decided to re-hire him again on co-op for the fall semester.

LEVELOGGERS

• We continue to upload dataloggers at the following locations on a weekly basis:
  • 1 on Saint Charles St. and 2 on Cazenove St.
  • 5 along the Storrow Drive Underpass from Embankment Rd. - Clarendon St.
• 4 loggers have been placed in wells in Back Bay closest to the alleys that BWSC are replacing lines and installing recharge systems
• Additional loggers have been placed in the Fenway, South End, and Back Bay.

CONTOURS

• We continue to generate contours for all areas of our well network. Elliott and I have reviewed them with our technical committee.
• We will continue to receive the contours from BWSC and will be sending them our contours for comparison.

ISD RESEARCH

• We continue to look for building permits and any underpinned buildings.
• I continue working on the South End.

WELL INSTALLATION

• We installed 14 OW’s from June 7th - June 25th in the Back Bay, South End, Fenway, and the Leather District. Our contract initially called for the installation of 17 OW’s. However, due to some utility interference and soil conditions 14 of the 17 were installed.
• Overall the operation ran relatively well. There were some minor hiccups here and there. The weather was great and once again New Hampshire Boring, Inc. executed fine work.
