Wastewater HappensHow We Deal with it is very
important!
Health Impacts Associated with Wastewater
• Can carry/cause Disease• Nitrates harmful effects on infants• Drinking water contamination • Coastal Impacts
• Plant Growth• Algae Blooms• Fish Kills• Shellfish Bed Closures
Residential Areas without a Centralized Wastewater System
Regulated by 310 CMR 15.00 Title 5
On-Site Subsurface Disposal Systems
Inspections Required for Sale of Home Periodic for Large Systems and
Condominiums Must Inspect
