Benefits of a Public Water System
 Superior
Well Construction
 Sanitary Defect Inspections
 Technical Financial and Managerial (TFM)
Framework required
 Continual Monitoring
 Proactive Approach to Contamination
 Technical Assistance from DEQ
Risks of Private Wells
 Many
conduits from surface to aquifer
 Each homeowner is fully responsible
 Monitoring non-existent or minimal
 Monitoring is costly ($1700-2200) for full
suite of contaminants
 Reactive approach to contamination (if
monitoring conducted/revealed)
