DEPTH TO GROUNDWATER TARGETS
Depth to groundwater targets were developed based upon input from the Town for protection of
critical infrastructure, shown in Figure 2.4. A depth to groundwater target of 18 feet was chosen
for areas of the Town south of County Road 42 and east of Birch Street based upon a 1.2-foot depth
of wastewater basins at the Town's wastewater treatment plant, depth of sewer lines and existence
of basements in the historically developed portion of Town. The Town has two wastewater pump
stations, one located at 12th Street and Ash Street and a second located at 8th Street and Elm Street
identified in Figure 2.4. A depth to groundwater target of 25 feet was chosen at these locations to
protect pump station infrastructure and minimize I&I. For all other areas of Town, a 15-foot depth
to water target was chosen to prevent I&I to existing and future wastewater collection facilities.
The depth to groundwater targets are conservatively deep and accommodate the relatively small
water level decline observed in some wells between 2014 and 2016.
GROUNDWATER LEVEL DRAWDOWN TARGETS
The depth to groundwater targets were subtracted from the April 2016 depth to groundwater
mapping to determine the amount of groundwater level drawdown required throughout the Town,
shown in Figure 2.5. The greatest drawdown targets are at the Town's two wastewater pump
stations and in the northeast portion of Town near the wastewater treatment facility.
