Many effective technologies and approaches are available to
improve water quality. Appropriate technologies can be used
to treat wastewater if funding is available to communities
to implement needed technology and infrastructure. A
tremendously cost-effective approach to improving water
quality is through pollution prevention. In cases where
contaminants result from domestic, industrial, or agricultural
activities, wastewater must be treated. When water quality
and watersheds are adversely impacted by poor water
quality, strategies to remediate pollution and restore
watershed functions are important.
Technologies and infrastructure to prevent, treat, and restore
water quality must be employed in every region of the world by:
• connecting communities, governments, and businesses
to effective water quality technologies and approaches;
• developing new technologies when needed to meet
the particular environmental or resource conditions in a
particular location;
• providing financing to implement needed technologies
and infrastructure projects;
