Groundwater

Groundwater is vital to the “Good Life” in Nebraska. It maintains our agricultural economy, supplies water to streams and lakes, and provides drinking water to municipalities and rural households. Nebraskans pump groundwater out of the High Plains aquifer and many other aquifers across the state. The vast majority of groundwater is used for agricultural production.

Groundwater regulation impacts on Nebraska land values

With new regulations being implemented in Nebraska because of falling groundwater levels, you may be wondering how they will impact the value of agricultural lands in those regions. Ag economists from the University of Nebraska - Lincoln and Daugherty Water for Food Global Institute analyzed what has happened historically. Their findings: Land values were unaffected by groundwater allocations. Neither allocations or well moratoria had any significant effect on the value of land that had already been developed for irrigation. Well moratoria reduced the value of dryland acres by 9%.

Drought year causes groundwater level decline

The annual Nebraska Statewide Groundwater-Level Report from the Conservation and Survey Division in the University of Nebraska–Lincoln’s School of Natural Resources shows that groundwater levels in the eastern half of the state continue to decline following several years of persistent drought.

Be Groundwater Aware in Your Day-to-Day Life!

National Groundwater Awareness Week is March 9–15, making it the perfect time to talk about groundwater in Nebraska! What exactly is groundwater? It is the water below the earth’s surface that fills the interconnected voids and cracks in and around soil particles, sand, gravel and rock — all of this is what we call an aquifer.

Managing Hard Water

Many parts of Nebraska have hard water. Hard water has a high mineral content; hardness primarily refers to the amount of calcium (Ca) and magnesium (Mg) dissolved in the water. Hard water is not just a private well owner’s problem, it affects many municipal water users, too. While hard water does not present a health risk for the vast majority of the population, it is often a nuisance for rural and urban homeowners across the state. Having your well water tested for hardness is helpful in assessing what treatment system will work best.

Aquifers of Nebraska

There are at least seven major aquifer systems in Nebraska. By far, the High Plains/Ogallala aquifer is the largest in terms of volume of water in storage and withdrawals for irrigation. Several secondary aquifers exist in areas outside of the High Plains aquifer, providing water for irrigation, municipal supplies, and domestic use in parts of far western and far eastern Nebraska.

Groundwater Quality and Protection

In many parts of Nebraska, the natural quality of groundwater is suitable for both humans and ecosystems. However, in some areas the groundwater quality has been impacted by high levels of nitrate from human activities, or naturally high levels of uranium or arsenic. These groundwater quality issues can cause significant challenges for communities, in part because of the cost of treating groundwater to reduce contaminants to meet drinking water standards.

Groundwater Levels

Groundwater levels are an indication of how humans and climate have impacted the amount of water stored below ground, and the amount of groundwater that flows out of the ground to streams, rivers, springs, and lakes. Depletion of groundwater resources would have major social, economic, and ecological impacts in Nebraska and beyond.

An Overview of Secondary Aquifers in Nebraska

Nebraska is a groundwater-rich state. Nebraska has one primary aquifer, the High Plains Aquifer, and seven secondary aquifers. These secondary aquifers supply water to more than 4000 active wells spread across 30 counties.

Celebrate (and check) your drinking water in May

National Drinking Water Week is held in May each year to bring attention to important water quantity and quality issues and their relationship to drinking water supplies.  The attention to drinking water during that week provides an opportunity to learn more water resources in general and also serves a reminder to think about where your water comes from.

Groundwater is vital to the “Good Life” in Nebraska. It maintains our agricultural economy, supplies water to streams and lakes, and provides drinking water to municipalities and rural households.
