Pesticides Illegal in Garbage & Drains Hazardous Waste Tahoe-Truckee Earth Day Festival Saturday, April 20, 2019 More Info Get Reminder Never Pour Down the Drain Pesticides should never be poured down the drain because they contain toxic chemicals that can contaminate waterways.

This runoff ends up in water drains that can contaminate lakes and rivers. It also makes your pesticides less effective against pests. Don't Use if It's Going to Rain Avoid using chemicals before a storm; if you do, they will be washed down storm drains, or leach into the soil, once it starts raining. Rinse Empty Concentrate Containers Containers that held concentrate need to be rinsed out three times before they are thrown in the trash: to do this, add remaining spray to the tank. Next, add water into the container, swirl and then transfer to the spray tank. Finally, repeat these steps twice. Ready-to-Use Containers Empty containers that held ready-to-use chemicals can be thrown in the trash without rinsing them out.

If you’re not going to use them up completely, try giving them to a friend. Avoid Purchasing Concentrate Consider purchasing ready-to-use products. Purchasing concentrations to dilute on your own can expose the body to harmful chemicals. Also the use of under-diluted chemicals is more damaging to the air, water and soil.
