If you've driven down Main Street in recent days, you've likely seen some activity on the site of our future Town Common. We are thrilled that site clean up is well underway. We've received mutliple requests from town residents inquiring about the remediation process. Below we have outlined the four phases to clean up:
1. Investigation -- the phase in which a number of subsurface soil and groundwater samples are taken to assess the condition of the site -- is now complete.
2. Characterization is the phase during which the results of the soil and groundwater testing are interpreted to determine the concentrations and extent of the contamination. This information is critical to developing the plan for the remediation of the site. This phase is essentially complete; however, some additional information will be provided prior to developing the remediation design alternatives.
3. Remediation Design determines the alternative approaches to the cleanup of the site. From these alternatives, a selection is made based on the intended use of the site and must be approved by the Massachusetts Department of Environmental Protection. This phase will begin mid-2015 after the charrette (collaborative design effort) is completed in January and a proposed design for the Common is complete. The design will ultimately determine which remediation design will be implemented.
4. Remediation -- the actual clean-up of the site -- may include a range of methods ranging from soil removal to capping and cover as required by the preferred alternative. We intend for the remediation effort and the final detailed build-out of the Common to occur simultaneously in order to avoid the cost of separate contracts and the associated mobilizing and demobilizing constru
ction contractors. This is currently planned for early 2016.
Once we have completed all four of these phases, we will be well on our way to transforming the current brownfield to a town green.
