How Green Cleaning Protects the St. Johns River Watershed

What Goes Down Your Drain in Jacksonville

When you spray your shower with conventional bathroom cleaner, mop your floor with chemical solutions, or dump that bucket of dirty cleaning water down the sink, where does it go? In Jacksonville, most of our wastewater flows through the JEA treatment system — which is excellent at removing biological waste but was never designed to filter out the complex chemical cocktails in modern cleaning products.

The St. Johns River, which runs right through the heart of our city, is the receiving water body for much of this treated discharge. And while treatment plants remove the worst of it, many cleaning chemicals pass through treatment systems and enter the river in concentrations that affect aquatic life.

The St. Johns Riverkeeper's 2023 water quality report found traces of surfactants, phosphates, and antimicrobial agents at multiple testing sites along the Duval County stretch of the river. At Clean Fix Jax, we believe that how we clean matters not just for your home, but for the river that defines our city.

The St. Johns River: Our City's Lifeblood

Why This River Matters

The St. Johns River is one of only 33 rivers in the United States that flows north. It stretches 310 miles from Indian River County to its mouth at Jacksonville, where it empties into the Atlantic Ocean.

The river and its watershed provide drinking water for millions of Floridians, support a $7 billion annual recreational and commercial fishing economy, and sustain one of the most diverse ecosystems in the Southeast — including manatees, bald eagles, ospreys, and over 180 species of fish.

But the St. Johns is also one of the most endangered rivers in America. The American Rivers organization listed it among the nation's most threatened waterways due to nutrient pollution, and the river suffers from chronic algae blooms caused by nitrogen and phosphorus loading. Every chemical that enters this system adds to the burden.

How Cleaning Chemicals Enter Our Waterways

The Path from Your Sink to the River

Here's the journey a cleaning chemical takes from your home to the St. Johns:

• Step 1: You use a cleaning product in your home. Residue rinses down the drain or is washed off during cleaning
• Step 2: Wastewater enters JEA's treatment system. Primary treatment removes solids; secondary treatment uses bacteria to break down organic matter. But many synthetic chemicals resist bacterial decomposition
• Step 3: Treated effluent is discharged into the St. Johns River. While it meets EPA standards for biological contaminants, it may still contain traces of surfactants, antimicrobials, phosphates, and volatile organic compounds
• Step 4: These chemicals enter the river ecosystem, where they accumulate in sediments and organisms

There's also a secondary pathway: when you clean your driveway, patio, or exterior surfaces with chemical cleaners, the runoff goes directly into storm drains — and storm drains in Jacksonville flow directly to the St. Johns River with ZERO treatment. Every chemical that washes off your property during rain goes straight into the river.

The Worst Offenders in Your Cleaning Cabinet

Chemicals That Harm the St. Johns Ecosystem

These common cleaning chemicals pose the greatest threat to our local waterways:

• Phosphates: Found in some automatic dishwashing detergents and floor cleaners. Phosphates are the primary driver of algae blooms in the St. Johns. When algae die and decompose, they consume dissolved oxygen, creating dead zones. Florida banned phosphates in laundry detergent in 2010, but they're still present in some dish and surface cleaning products
• Triclosan: An antibacterial agent found in some hand soaps and cleaning products. Triclosan is toxic to algae (the base of the aquatic food chain) and has been detected in St. Johns River sediment samples
• Nonylphenol ethoxylates (NPEs): Surfactants used in some industrial and commercial cleaners. When these break down, they produce nonylphenol, which is an endocrine disruptor that feminizes male fish. The European Union banned NPEs; the US has not
• Quaternary ammonium compounds (quats): The active ingredient in many antibacterial wipes and sprays. Quats are toxic to aquatic organisms at very low concentrations — as low as 0.1 parts per million for some species. They also don't break down quickly in the environment
• Ammonia: Toxic to aquatic life. When ammonia enters waterways, it's converted to ammonium, which is a source of nitrogen — another driver of algae blooms
• Chlorine bleach: Reacts with organic matter in water to form trihalomethanes and other disinfection byproducts that are toxic to aquatic organisms

How Green Cleaning Protects the Watershed

Biodegradable Ingredients Break Down Naturally

The key difference between conventional and green cleaning products is what happens after they go down the drain. Conventional products contain synthetic chemicals designed to be stable — they resist breaking down because that's what makes them shelf-stable and effective. But that same stability means they persist in the environment.

Green cleaning products use plant-derived, biodegradable ingredients that microorganisms in treatment plants and natural waterways can break down into harmless components:

• Plant-based surfactants (from coconut, corn, and sugar) biodegrade by 95-99% within 28 days, compared to 30-60% for petroleum-based surfactants
• Citric acid (from lemons) breaks down completely into water and carbon dioxide
• Acetic acid (vinegar) is naturally present in the environment and breaks down immediately
• Enzymes used in green cleaners are proteins that break down into amino acids — harmless building blocks of life

No Nutrient Pollution

Quality green cleaning products are phosphate-free by design. When you switch from conventional dish detergent to a phosphate-free alternative, you directly reduce the phosphorus load entering the St. Johns River. If every household in Duval County made this single switch, it would remove an estimated 12,000 pounds of phosphorus from the river system annually.

Practical Steps for Jacksonville Homeowners

What You Can Do Today

• Switch to phosphate-free dish detergent: Seventh Generation, Ecover, and Puracy all make effective phosphate-free options ($4-6 per bottle)
• Never clean outdoor surfaces with chemical cleaners: Use a pressure washer with plain water, or for tough stains, use a vinegar solution
• Choose plant-based, biodegradable products: Look for EPA Safer Choice certification on labels
• Avoid antibacterial products: Unless someone in your home has a compromised immune system, you don't need antibacterial soaps and sprays
• Properly dispose of hazardous products: Take old chemicals to the Household Hazardous Waste facility at 2675 Commonwealth Avenue in Jacksonville
