Water Quality & Conservation
What's the problem?
The Biscayne Aquifer is the primary source of drinking water for Miami-Dade and Broward County residents. It is made of limestone and is a productive aquifer, meaning it is very porous. The State of Florida manages this water resource and lets utilities dig wells into the aquifer to reach the freshwater and bring it up for consumers. Some risks that face the aquifer are contamination, over-pumping and saltwater intrusion. Another threat to the safety of Florida’s waters is the redirection of naturally flowing water. Water from Lake Okeechobee used to pour into the Everglades. However, since artificial canals have been adopted, the water received by the Everglades is lower in quality. Aside from freshwater, our ocean is also at risk. Harmful algal blooms, plastic pollution, and climate change threaten the health of our coastal and marine ecosystems.
Why should we care?
The Biscayne Aquifer is recharged by rainfall because it is close to the surface. The aquifer is also classified as unconfined, meaning there is a minimal shielding layer of substances, like clay, to protect from external pollutants. This leaves the aquifer vulnerable to contamination by pesticides, gas, oil, and chemicals from degrading waste. As the population of Florida increases, we risk withdrawing water from the aquifer faster than it is being recharged. Sea level rise from climate change has also increased the rate at which saltwater infiltrates the groundwater. This will eventually make it too saline for consumption. Alternative costly solutions may need to be used. Access to clean water is a right, not a privilege. Low-income and communities of color bear the brunt of the burden of polluted water, leading to increased risk for health issues. Our wellbeing is also very dependent on the health of our coastal waters. They provide us with climate regulation, food, and a thriving economy among other things. The Florida Ocean Alliance estimates that in 2020 alone, “direct and indirect use of ocean and coastal resources contributed $73.9 billion to [Florida’s] economy.”
What can we do?
What can we do?
Protecting our water resources is a priority for Miami-Dade County. The Miami-Dade Water and Sewer Department has put together a comprehensive list of tips to help conserve water. Some easy solutions include switching to more water-efficient models like low-flow shower heads, faucets, and toilets. The County offers numerous rebates and sometimes even free exchange programs to help. This year, we are also proud to partner with the Ocean Conservancy and share the amazing work they have done in setting out a vision for Florida’s ocean and coasts. “We know this is a phenomenal challenge - to imagine and then realize a Florida whose beaches are (even more) vibrant, whose waters are clean and accessible to all, and whose ocean is thriving and providing for millions. We are up to the challenge - and we hope that you are, too.” Janis Searles Jones, Chief Executive Officer.
