Fireworks contain Persistent, Bioaccumulative, and Toxic chemicals (PBTs) like copper, lead, perchlorate, and lithium to create their effects and remain on firework debris. PBTs remain in the environment for very long periods of time, are highly resistant to degradation, easily enter and quickly accumulate in the food chain and can be toxic to both humans and animals.
– Please pick up firework debris. Let spent fireworks sit only until they’re not longer hot or burning then move them to a bucket with water.
– Water used to soak spent fireworks should be flushed in a toilet so the water can be treated at the wastewater treatment plant. Please do not pour the water down the gutter or on the lawns to avoid contaminating ground and water with PBTs.
– Sweep small firework particles and put them in a plastic bag for disposal in the trash. The particles are prone to travel in the wind or in water runoff spreading PBTs to soils and waterways.
Over 90% of Rocky Mountain rainwater samples gathered for a United States Geological Survey contained microplastics, plastics less 5 mm or less. While urban samples contained more plastic, samples from remote sites indicate microplastics may be more pervasive.
Some microplastics are released as tiny particles like fibers from synthetic clothing or car tire fragments. Others fibers come from the breakdown of larger plastic items like bags and bottles. The particles migrate and have been found in the remotest parts and people on the planet.

Stormwater runoff has a knack for being able to transport whatever it comes into contact with as it makes its way downstream. Sediment, debris, stones…all are susceptible to it’s force.
The primary advantages of tree box filters include ease of construction and simple, cost-effective maintenance. Plant selection allows for a good blend into the environment. Maintenance is normally done with a rake and shovel to remove spent mulch and captured trash.
It takes just as much effort to cut the grass and shoot it into your yard as it does to shoot it into the street. The difference is that it’s a GOOD THING to put it in your yard and a BAD THING to put it in the street. People notice these things.
