The following LSPA practice tip was introduced at the February 2024 Membership Meeting, which was held remotely on February 13, 2024 via Zoom.  

Practice Tip of the Month
Many municipalities have areas designated for the protection of groundwater quality to ensure its availability for use as a source of potable water supply (e.g., Aquifer Protection Districts).

When classifying groundwater, be aware that these areas, which are established by local rule, are not shown on MassGIS or the MCP Phase 1 Site Assessment mapping tools. Being within a local Aquifer Protection District will categorically drive the groundwater classification of a Site to GW-1, even if it lies within a designated Non-potential Drinking Water Source Area (NPDWSA) area as shown on the mapping tools.
