Water Quality

Testing private drinking water supplies in Nebraska is not required by federal or state regulation, with some exceptions such as licensed childcare facilities and foster care home water supplies. County or city jurisdictions may have requirements for private water supply testing.

Have you ever wondered about the water quality in your favorite lake?  Or perhaps you’ve planned a day at the lake only to see a sign that says “Health Alert” and not known what that meant. 

Odors that can be compared to rotten eggs are not ideal in your home or coming from your drinking water faucet.  Sulfates, which are a combination of sulfur and oxygen, are naturally occurring minerals.  They are found in some soil and rock formations where groundwater is also found.  Bacteria that feed on sulfur can produce hydrogen sulfide gas which is the primary offender when it comes to odor. 

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.

Protecting the quality and safety of your water supply means protecting your well and the area surrounding it by not storing hazardous materials including fuel, metals and chemicals near the well, keeping livestock including horses away, and limiting applications of lawn chemicals immediately around the well. However, to protect your water supply you need to look beyond the area immediately around your well.

Discolored water. A strange odor. Stained ceramic fixtures such as tubs, sinks and toilets. Discolored clothes, towels and dishes. Reduced water pressure.  These are all some of the potential impacts from high levels of iron and manganese in your water supply. 

National Septic Smart week is Sept. 17–21, 2018. The U.S. Environmental Protection Agency (EPA) uses a week in September each year to focus on improved awareness of proper operation and maintenance of septic systems across the U.S.  The wastewater of approximately 25 percent of the population of the U.S. is treated by on-site or individual wastewater systems. In Nebraska, that statistic holds consistent with approximately 25 percent of our state’s population served by onsite wastewater systems on farms, acreages, suburbs and even some small communities.

The City of Auburn, population 3,000, is located in southeast Nebraska, near the Little Nemaha River, approximately seven miles upstream of its confluence with the Missouri River. The City receives its drinking water from a wellfield located east of the community within an alluvial aquifer along the Little Nemaha River. The wellfield consists of 11 vertical wells averaging 45 to 50 feet below the ground's surface, pumping up to 150 million gallons per year.

Have you ever wondered why groundwater nitrate maps show so much variation across Nebraska? Or why wells near to your own tested well have such different nitrate levels? The answer has three parts. Nitrate in groundwater varies from place to place because of differences in:
