A wastewater treatment facility currently under construction in Falmouth, Massachusetts, features a dual disposal method for land application of effluent. As the effluent disposal site is considered part of Cape Cod's sole-source aquifer, comprehensive groundwater investigations were required before the proposed facility was approved by EPA and state regulatory agencies. The DYNFLOW and DYNTRACK simulation models were used to represent the local groundwater system. The simulation results showed that the plume from the treatment site would not move towards Long Pond nor would its hydraulic effects 'deflect' an existing landfill plume into the Long Pond drainage basin. Based on the modeling results, the Town notified about 300 property owners in the area, restricted future use of private potable groundwater supplies, and extended municipal water supplies to 11 properties in the affected area.
