Appendix D 103402.0001 Springfield Township, Bucks County, PA Springtown Source Water Protection Plan Executive Summary Springfield Township has initiated a source water protection program for the Village of Springtown. The project was funded through the assistance of a source water protection grant from Pennsylvania Department of Environmental Protection (PADEP). The program participants include a steering committee of local and regional stakeholders and a technical committee of environmental professionals. The goal of the wellhead protection program is the creation of a management plan that addresses specific concerns and potential threats to the quality and quantity of the public water supply. This report summarizes the components of the wellhead protection program and includes the necessary elements for PADEP approval. 1. Steering Committee A steering committee was formed to provide information, offer guidance, and implement the wellhead protection activities. 2. Public Participation Public participation was encouraged through informational and education activities conducted throughout the program. 3. Source Water Protection Area Delineations The source water protection areas were delineated for the single well and three groundwater springs with a hydrogeologic computer model. 4. Potential Sources of Contamination An inventory of potential sources of contamination within the delineated wellhead protection areas was generated and evaluated through a susceptibility analysis to assess the risk to groundwater quality. 5. Management Approaches Based on the wellhead protection area delineations and potential sources of contamination inventory, a wellhead protection area management plan was developed with an emphasis on land use planning and public education. 103402.0001 1 6. Contingency Planning The source water protection plan will be incorporated into the Springfield Township Emergency Response Plan. 7. New Source Protection Springfield Township has identified potential locations for new water supply wells if needed. The wellhead protection management of the potential new source well(s) is incorporated into the wellhead protection program and management plan for the existing wells. The implementation of this source water protection management plan will be carried out through a joint effort of Springfield Township and neighboring Lower Saucon Township, which includes part of the protection area for Springtown’s water supply. 103402.0001 2 1.0 Introduction Springfield Township, Bucks County has initiated a wellhead protection program for the water supply for the Village of Springtown. The Springfield Township Authority applied for and received a source water protection grant (ME3511172, May 2002) from the Pennsylvania Department of Environmental Protection (PADEP). After the grant was awarded, Springfield Township took over the obligations of the Authority; in January 2004, the Township directed the Springfield Township Environmental Advisory Council (STEAC) to proceed with development of the plan. Lower Saucon Township, located north of Springtown, supported the grant; part of Springtown’s source water protection area lies within Lower Saucon Township. The goal of the plan is to provide management options to Springfield Township and
