Pet Waste

Be the solution and help Stop Poo-llution in San Mateo County!

be the solution - stop poo-llution from pet waste

Pets bring joy and companionship, but their waste can create environmental challenges when not managed properly. A single gram of dog waste can contain 23 million bacteria!

When pet waste is left on the ground, it can be washed into storm drains by rain or runoff, eventually making its way to streams, creeks, the San Francisco Bay or the Pacific Ocean. While certain types of ‘poop’ can make good fertilizer, dog waste in particular does not. For most plants it is actually too acidic, due to their diets, which often causes burning and browning if left on plants and grasses for too long.

Why is it important?

Pet waste is a significant source of pollution that can affect both human health and the environment. According to the EPA, the bacteria found in pet waste can lead to illnesses such as salmonellosis, toxocariasis, and toxoplasmosis. These pathogens can be transmitted through contaminated soil, water, or direct contact, which creates risks to both people and wildlife, especially aquatic wildlife. Children and those with compromised immune systems playing in parks or in waterways are at greater risk.

How You Can Help

Addressing pet waste is a key step in maintaining good water quality, and everyone can participate.

Pick it up and bag it!

Always carry poop bags to clean up after your dog. Dispose of the bag in a proper trash receptacle—leaving bags in parks or trails is considered littering and may result in fines. Promptly picking up waste helps prevent soil and water contamination. Although plastic bags are not environmentally ideal, the pollution from untreated pet waste poses a greater environmental hazard. Landfills are designed to manage waste safely.

Do Not Compost Pet Waste!

Pet waste is not suitable for composting. It contains parasites and pathogens that can pose health risks. Stick to putting it in the trash to ensure safety.

Fixit Clinic @ Half Moon Bay Library

Fixit Clinics are fun community-based workshops where neighbors, friends, and families work collectively to learn how to repair broken items. We’ll provide a workspace, specialty tools, and volunteer Fixit Coaches to help you troubleshoot and provide routine maintenance to your household items and appliances! Register at https://bit.ly/itemcheckin. 

Interested in being a Fixit Coach?
It’s easy! Provide participants with 1) guidance on tools and 2) encouragement to investigate their broken item. Let them talk about how they used it and how it broke. That often provides valuable hints as to what’s wrong. See how much you can do without actually handling the item. Empower the item’s owner to do the troubleshooting and disassembly. Register to be a Fixit Coach here.

This event is hosted in partnership with the San Mateo County Libraries.
