For trash to get from Kearney, NE to the Gulf of Mexico it must first travel nearly 2,000 miles. However, there are many opportunities for it to get caught up in shoreline of the rivers on the way there. Either way, it’s not good for the environment.
Continued melting means flowing snow melt and runoff. Check street gutters and storm drains near your home to make sure they’re clear of debris and functioning properly.
Clogged storm drains can cause neighborhood flooding, icy back up and nutrient overload as debris decays in the drains.Removing leaves, one of the largest urban sources of phosphorus pollution, from street gutters and drains can reduce the amount of phosphorus in urban runoff by 80% (USGS 2016).
Urban snowmelt runoff carries diverse pollutants, like gas combustion products, snowmelting agents, and automotive exhaust, which threaten the quality of the receiving waters, like the North Platte River.
Pollutants can affect water quality faster two ways in winter. First, snow collects contaminants and releases them in concentrated form during melts. Second, the partially frozen state of rivers lessen the ability for self-purification.
Keeping walks and driveways clear, using snowmelt “sparingly and caringly”, and driving only when necessary are good winter water quality measures.
As much as 75 percent of water supplies in some western states are derived from snowmelt, according to the United States Geological Service (USGS). The Nebraska Panhandle relies heavily on snowmelt for our water supply – so taking care of our snow means taking care of our water.
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.
Recent research suggests rain harvesting may have provided the 800 Roman soliders manning Hadrian’s Fort with 10 liters (2.62 gallons) of drinking water per per capita per day during their deployment.
Evidence at Hadrian’s Fort, a strategic Roman outpost along Hadrian’s Wall in northern England, indicates building rooftops were constructed to capture rainfall. The runoff collected in stone-lined tanks, two to six tanks per key building, capable of holding 2 cubic meters (about 528 gallons) of water each.
It’s an amazing feat of foresight, considering Hadrian’s Fort has no internal springs or wells, access to springs or waterways in the region, and an aqueduct supply would have been extremely impractical.

Stormwater is not treated before it flows into the North Platte River, so contaminants that enter the storm sewer system can also contaminate the river.
According to regulation, anything other than rain or snowmelt in the storm sewer is an illicit discharge. However, clean water discharges to the gutter – like pumped groundwater, air conditioning condensation, or irrigation water/lawn watering – are typically excused.
If you see or find evidence of substances other than rain or snowmelt in the gutter or near a storm drain please call the stormwater department 630-8011. If the spill is over 25 gallons or you know the substance is hazardous, please call 911.
