MWRA Contractor to Conduct Soil Boring and Test Pit Work in Waltham

The Massachusetts Water Resources Authority (MWRA) is planning to upgrade water transmission pipes in your area. As part of the design effort, MWRA has hired Green International Affiliates, Inc. and other firms to perform sub-surface exploration activities on/near existing pipelines or in areas where new water pipes could be constructed.

The soil boring and test pit activities involve blocking off a small area of the road with a truck and a boring rig, digging and drilling down to a depth of 15 to 35 feet and removing the soil samples.

At each location the work will take 4-5 hours. MWRA has 13 sites planned for Waltham. The locations are listed in the table below.
