Environmental Health Perspective, National Institute of Health
Water Resources Program
Point Source Pollution
• Comes from a
specific source, like a
pipe
• Factories, industry,
municipal treatment
plants
• Can be monitored
and controlled by a
permit system
(NPDES)
Water Resources Program
Nonpoint Source Pollution
• Nonpoint Source (NPS) Pollution is pollution associated with stormwater or runoff
• NPS occurs when runoff collects pollutants on its way to a collection system or water body
• NPS pollution cannot be traced to a direct discharge point such as a wastewater treatment facility
Water Resources Program
Impacts of Nonpoint Source Pollution
• Fish and wildlife
• Recreational water
activities
• Commercial fishing
• Tourism
• Drinking water quality
Water Resources Program
What is infrastructure?
• Infrastructure
includes the basic
structures and
organizations needed
to operate our cities:
– roads
– water supply
– sewers
– electrical grids
– telecommunications

Water Resources Program
Green Infrastructure…is an approach to stormwater management that
is cost-effective, sustainable, and environmentally
friendly.
Green Infrastructure projects:
• capture
• filter
• absorb
• reuse
stormwater to help restore the
natural water cycle.

Green Roofs
• Green roofs provide
numerous functions:
– improving stormwater
management
– improving air quality
– regulating temperature,
which moderates heat
island effect
– provides carbon dioxide-
oxygen exchange
– increases wildlife habitat
