How Harford County Homeowners Can Clean Responsibly in the Chesapeake Bay Watershed

Harford County sits in the upper watershed of the Chesapeake Bay — the largest estuary in the United States. The water that flows off our roofs, through our storm drains, and down our pipes is part of the same hydrological system that sustains the Bay's ecosystem. For Harford County homeowners, this creates a particular responsibility.

This isn't about guilt — it's about understanding how everyday choices at home connect to one of the most important ecological systems in the mid-Atlantic region.

How Cleaning Products Reach the Bay

Most household cleaning products go down drains and enter the municipal wastewater treatment system. Treatment plants remove many contaminants, but not all. Some compounds pass through treatment and enter waterways — eventually reaching the Bay and its tributaries.

For septic system users (common in rural Harford County), the connection is more direct: wastewater is treated on-site and then percolates into groundwater, which connects directly to streams and the Bay watershed.

The specific compounds of concern:

Phosphates: Once common in dishwashing and laundry detergents, phosphates contribute to algal blooms in the Bay. Maryland has restricted phosphates in cleaning products, and most modern formulations have removed them — but some older or imported products still contain them.

Nitrogen compounds: Certain surfactants and cleaning chemicals break down into nitrogen compounds, which also contribute to nutrient loading and algal growth in the Bay.

Triclosan and antibacterial agents: Antimicrobial agents in cleaning products pass through wastewater treatment and have been detected in Bay tributaries. They affect aquatic organisms and can contribute to antibiotic resistance.

Synthetic fragrances: Many fragrance compounds are persistent in aquatic environments and have demonstrated hormonal effects on fish and other aquatic life.

What the Bay Research Shows

The Chesapeake Bay Program has documented that household sources — including cleaning products, lawn care products, and pharmaceuticals — contribute measurably to nutrient loading in the Bay. This nutrient loading drives the dead zones (hypoxic areas) that form in the Bay each summer, killing fish and crabs and reducing oxygen for the organisms that sustain the Bay's food web.

Harford and Cecil County, as upper-watershed counties, have an outsized influence on what eventually reaches the water.

What You Can Do

Choose EPA Safer Choice certified products. The EPA Safer Choice program evaluates ingredient safety for aquatic toxicity — products bearing this certification have been reviewed for their environmental impact, not just their cleaning effectiveness. This is the most reliable standard for identifying products that are safer for the Bay watershed.

Avoid antibacterial soaps and cleaning products unless there's a specific medical need. Regular soap removes germs effectively without the environmental tradeoffs of triclosan and related compounds.

Check for phosphates in dishwasher detergents. While banned in many formulations, some products still contain them. The ingredient list is the only reliable way to check.

Don't pour cleaning products down storm drains. Storm drains go directly to waterways without treatment — unlike sink drains, which pass through the wastewater treatment system. Dispose of cleaning products through household hazardous waste programs.

Maintain your septic system. For rural Harford County homeowners, a properly functioning septic system is the difference between treated wastewater percolating into groundwater and raw sewage reaching nearby streams.

Professional Cleaning and the Bay

At Chesapeake Premier Cleaning, we exclusively use EPA Safer Choice certified products — not as a marketing claim, but as a genuine commitment to the community we live in. Our team cleans in Harford and Cecil County every day of the week. The products we use in hundreds of homes each month add up in the watershed.

We chose the Safer Choice standard because it addresses aquatic toxicity specifically — the compounds that our products release into the Bay watershed after they go down drains. It's the right approach for a cleaning company operating in this specific geography.
