The Issue
Understanding water quality and how you can help
The Basics
What Is Water Quality and Why Should You Care?
Water quality describes how clean and healthy water is for people, wildlife, and coastal ecosystems. When water quality declines, the effects ripple outward—impacting beaches, fishing, wildlife, tourism, and local communities.
A Unique Ecosystem
Why Sanibel's Water Is Special
Sanibel sits at the intersection of rivers, estuaries, and the Gulf of Mexico. This mix of freshwater and saltwater supports seagrass meadows, fish and shellfish, birds, dolphins, and manatees.
Healthy water keeps these systems in balance.
The Challenges
What Affects Water Quality?
Water quality is influenced by things we do not always see:
Runoff from streets, lawns, and parking lots
Excess nutrients from fertilizers and wastewater
Boat activity that disturbs seagrass
Changes in freshwater flow
Many of these pressures start far from the coast—which means solutions do too.
Small Choices. Real Impact.
Protecting water does not stop when your vacation ends. The same actions that help Sanibel's waters help rivers, lakes, and coastlines across the country.
