Nebraska’s Wellhead Protection (WHP) Program is a voluntary program which assists communities and other public water suppliers in preventing contamination of their water supplies. The Nebraska Legislature passed LB 1161 in 1998 (Neb. Rev. Stat. §46-1501 – 46-1509) *, authorizing the Wellhead Protection Area Act. This Act sets up a process for public water supply systems to use if they choose to implement a local Wellhead Protection plan. The Nebraska Department of Environment & Energy (NDEE) is the lead agency for Wellhead Protection (WHP) Plan approval.
The goal of Nebraska’s Wellhead Protection Program is to protect the land and groundwater surrounding public drinking water supply wells from contamination. Since approximately 85% of Nebraskans receive their drinking water from groundwater, preventing groundwater contamination is vital.
The Wellhead Protection planning process includes identifying the land surrounding the public water supply wells to be protected, identifying potential sources of groundwater contamination within this area, and managing the potential contaminant sources. Emergency, contingency, and long term plans are also developed for the community water supply, all the while educating and involving the public.
Delineating the Wellhead Protection Area
A Wellhead Protection area is calculated from information such as the geologic material the well is drilled into and the annual pumpage of the well. Computer-generated flow lines depict the approximate path groundwater, or a contaminant in groundwater, will take to reach a well. Flow lines are then associated with estimated times-of-travel and a boundary is drawn on property lines enclosing all 20-year-flow lines. The Nebraska Department of Environment and Energy (NDEE) provides these maps at no charge.

A Wellhead Protection map is just a piece of scrap paper unless you enact local ordinances, county zoning, or voluntary activities within your Wellhead Protection Area.
Potential Contaminant Source Inventory
The purpose of a potential contaminant source inventory is to identify potential contaminants that may pollute groundwater. Inventories should be compiled from existing databases and on-the-ground observations. Contact the NDEE Wellhead Protection Program for spreadsheets and shapefiles from existing databases.
- Inventory completed/updated within the past 3 years
- Contaminants marked on a map (point sources)

Common Potential Contaminant Sources:
Commercial / Light Industry
- Fuel Storage
- Grain Storage

- Chemical Storage
- Auto Repair
- Dry Cleaners
- Fuel Stations/Storage
- Machine Shop
- Rail Yard
- Gas/Oil Well
- Junk Yard
- Sewage Treatment
- Golf Course
- HWY Maintenance Yard
- Transportation Corridors
Contaminant Source Management
Management of a groundwater supply by local communities can involve a number of possible steps. These may include the enactment of sanitary and water ordinances, public nuisance laws, and zoning restrictions on specific land uses; the purchase of land or conservation easements; cooperative efforts with local NRDs; or voluntary actions. Best Management Practices should be encouraged throughout the Wellhead Protection area. Some water systems subsidize or even completely fund these practices.
Example Best Management Practices in Urban Settings:
- Develop a list of existing controls
- for example: setback distances for wells, backflow ordinances, limitations on fuel/chemical storage, limitations on confined animal feeding operations, etc.
- Develop or suggest new controls
- Include copies or descriptions of inter agency agreements (if any)
- Alternative Lawn Options
- Improving Soil Structure
- Installing Water Meters
- Low Flow Nozzles
- Mulching Lawn Clippings
- Permeable Pavement
- Rain Barrels / Rain Gardens
- Rain Sensors for Lawn Irrigation
- WHP Area Signs
Example Best Management Practices in Ag Settings:
- Alternative Cropping Methods
- Conservation Reserve Program
- No-Till Cultivation
- Nutrient Management Program (soil testing)
- Strip Cropping
- Water Management Program
- WHP Area Signs
Emergency, Contingency, and Long-Term Planning
A plan is developed to provide a replacement source of drinking water in the event of:
- Shut down of well due to contamination
- A natural disaster that impacts wells: flood, tornado, drought, ice storm
- Major mechanical or physical breakdown of pump, water tower, or distribution system
- Vandalism to well, water tower/storage, or supply source
- Include or reference a copy of your emergency plan
- Identify a safe short-term, temporary source of drinking water
- Identify options for obtaining a new long-term source of water
- Possible locations of a new well
- Other Public Water Systems to purchase water from
Public Education & Participation
Through state agencies, local groups, and environmental organizations, the public needs to be informed throughout the process and educated about what can be done to protect groundwater and their drinking water.
- Make the Wellhead Protection Plan available for public review at least 30 days prior to the meeting where public comment on the Plan will be taken/recorded
- Take public comments at a regularly scheduled meeting of the controlling entity (village board, city council, RWD board, etc.)
- Public notice both of the above
- Provide proof of public meetings and public notices
Numerous funding options are available for everything from paying someone to develop a plan to implementing on-the-ground management practices. Sources of these funds may include:
