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.
Post-Construction Stormwater Management is the most recently implemented MCM in the SWMP. For projects to require Stormwater Treatment Facilities they need to have been preliminary platted after Sept 1, 2017 and greater than an acre in size.
The City of Kearney’s IDDE Program depends a lot on the ‘eyes on the ground.’ In order to identify issues such as discharges that could negatively impact stormwater pollution, the City of Kearney relies on communication within its departments and the citizens of our municipality. There are established ways of communication: 308-233-3273; email@example.com; and ‘Access Kearney’ at www.cityofkearney.org.
