• 185 Wells @ elevation >7’    (26%)
• 309 wells @ elevation 5’- 7’    (44%)

We have read 89 wells in the East network (East Boston Area). Wells were read in East Boston from November 6-7, 2006. Of the 89 wells read:

• 45 wells @ elevation >7’    (51%)
• 14 wells @ elevation 5’- 7’    (16%)
• 11 wells @ elevation 3’-5’    (12%)
• 19 wells @ elevation <3’    (21%)
• 0 wells @ no reading    (0%)

NOTE: Percentage numbers reflect the percentage of well elevations in proportion to the number of wells in each network.

LEVELLOGGERS

• Group 4 dataloggers have been installed in 20 wells. Data is scheduled to be uploaded the second week in December.
• As per agreement with GEI Consultants Inc., loggers (there are a total of 4) installed in and around Cazenove St. are uploaded once a week and sent to GEI Consultants Inc. The purpose is to observe the water levels in the area where the recharge systems have been installed.

ISD Research

• We continue to look for any underpinned buildings.
