Odds are if you’re reading this, you rely on groundwater or well water as a primary source for the water you use in your daily life. Nearly 50% of all American households and businesses depend on groundwater, which is why it is important to be informed about the quality of the water you drink, cook and wash with, or utilize in all manner of municipal and manufacturing activities.

Groundwater is a renewable natural resource (1). The term refers specifically to the water that is absorbed into the soil from rain, snow, and other forms of precipitation in the Earth’s hydrologic cycle (1). This also means that anything else that gets into the soil—chemicals, contaminants, industrial gasses, insecticides and herbicides—ultimately may get into the groundwater drawn from that soil. Whether you are a homeowner, business owner, or public official charged with protecting and monitoring water for your municipality, it is important that you are aware of the quality of the groundwater you so depend on—and know what to do to treat water affected by industrial and agricultural runoff.

Consider these important facts about groundwater from the National Groundwater Awareness Association (1):

  • 90% of our freshwater resources are underground groundwater
  • Americans use 79 billion gallons of groundwater per day
  • more than 13 million households rely on private groundwater wells
  • approximately 500,000 new residential wells are created each year
  • 44% of Americans rely on groundwater for its drinking water supply
  • irrigation accounts for 67% of all groundwater used each day

The Ogallala aquifer, which stretches underground 250 thousand square miles from Texas to North Dakota, is the largest aquifer in the U.S. If you took all the water in the Ogallala and released across the country, it would cover the entire continental U.S. in 1.5 feet of water (1)! About 90% of the groundwater in the Ogallala is used for irrigation of crops (1). Anything that runs off from those crops—like insecticides and herbicides—can make its way back into the groundwater that constitutes the Ogallala aquifer. If you are a homeowner with a private well or a municipality that draws residential water from the Ogallala, it is essential that you know what chemicals and contaminants are in the groundwater your families use and ingest every day.

Culligan celebrates the importance of National Groundwater Awareness Week because for more than 75 years now, we have been pioneering innovation in water treatment and filtration for homeowners and commercial entities. The best way to know what is in the groundwater your family or business relies on everyday is to have your water tested by a professional. Your area Culligan Man is familiar with the water conditions in your community and will be able to test the water coming into your house for all manner of runoff and other contaminants. Your Culligan Man can suggest the most appropriate solutions to ensure you have the best water possible.

So during National Groundwater Awareness week, Culligan urges you to make knowing what’s in your water a priority.
