Strategies with this rating are likely to work, but further research is needed to confirm effects. These strategies have been tested more than once and results trend positive overall.

Health Factors  
Decision Makers

Multi-component groundwater management programs combine statewide and local level efforts to monitor and protect underground water resources. Such programs often include regular groundwater monitoring, education about risks to groundwater, resources to limit water contamination (e.g., tools for appropriate pesticide and fertilizer application, wastewater disposal, and soil tillage), water quotas and taxes, and support for program enforcement. From state to state, program designs vary significantly, with different degrees of local authority and control over monitoring, enforcement, and modification efforts1. Groundwater management programs may also be a part of broader efforts to protect source water for public drinking water supplies and private wells; source water can come from above ground sources such as rivers, streams, lakes, and reservoirs, or from groundwater beneath the surface2.

Expected Beneficial Outcomes (Rated)

  • Increased use of water management practices

  • Improved water quality

Other Potential Beneficial Outcomes

  • Increased water conservation

  • Reduced soil erosion

  • Reduced run-off

Evidence of Effectiveness

There is some evidence that multi-component groundwater management programs increase use of water management best practices3, 4, and improve water quality5, 6, 7, 8. However, additional evidence is needed to confirm effects, especially at the catchment level6.

Multi-component groundwater management programs can increase closure of abandoned wells, use of safeguards in pesticide storage and handling, well water testing, nutrient best management, and integrated pest management practices3, 4. Soil and water conservation practices can reduce soil loss, as well as water, pesticide, and excess nutrient runoff4, 5, especially from individual plots and fields7.

At catchment scale, current programs appear to be less effective, often due to their voluntary nature, insufficient financial rewards, unclear farm costs, or insufficient regulatory pressure and monitoring7. Experts suggest that increased monitoring and regulation of these programs at the catchment level could improve their effectiveness5, 7, 9.

One California-based study suggests regional source water protection plans offer an opportunity to address inequities in rural access to safe, affordable drinking water and water management planning. However, especially among small, rural communities of color with low incomes, limited power and resources can prevent participation in regional strategies. Efforts to support rural community participation are suggested to avoid further establishing historic inequities in water provision, access, and quality10. Farmer participation is also important to understand the feasibility and implications of regional water governance plans11, 12.

Successful efforts to promote sustainable groundwater management incorporate scientific knowledge about aquifers, climate, and habitat characteristics; understand the legal, economic, political, and historical context surrounding groundwater rights and use1; seek out and incorporate community feedback to solve problems continuously13; and use landscape scale planning as a tool to consider land use changes over time14. Local design and implementation plans may be more successful for settling conflicts between groundwater users than top-down efforts15. Groundwater management programs can use taxes on pumping groundwater to reduce aquifer use, though education efforts may also be needed to improve the political acceptability of such tax policies16.

Inconvenience, ignorance, and cost can be barriers to implementing groundwater management practices for private well owners. Including educational materials and regulatory enforcement in multi-component programs may overcome such barriers17. Surveys suggest many groundwater management programs face staffing limitations and budget decreases, and issues with declining groundwater quality and quantity often due to contamination and overuse18. Timing and frequency of management decisions, especially relative to irrigation season, can influence the effectiveness of groundwater management efforts19.

Implementation Examples

There are many groundwater management programs in the US. Examples include state-level programs such as those established by the Sustainable Groundwater Management Act in California20, Florida’s Ground Water Program21, Minnesota’s Department of Natural Resources Groundwater Management Program22, and the Texas Commission on Environmental Quality’s groundwater protection programs23. In Arizona, regional Active Management Areas (AMAs) coordinate state and local efforts to regulate groundwater use, with a goal of achieving safe yield, or withdrawing no more groundwater than is being replaced annually, by 2025. Some AMA initiatives include efforts to capture surface water and use it to replenish underground water supplies24.

Many regional or municipal areas have programs such as the Sacramento Groundwater Authority’s Groundwater Management Plan25, the Las Vegas Valley Groundwater Management Program26, and the King County Groundwater Protection Program in Washington27. In Kansas, five regional Groundwater Management Districts address groundwater depletion and declining groundwater quality, often using intensive local conservation and enhanced management plans28. In Nebraska, 23 local Natural Resources Districts (NRDs) have been established based on river basin boundaries; NRDs have state support, local authority, and mandated responsibilities for groundwater protection and preservation and 11 other focus areas, including protection for surface water resources, from flooding, against soil erosion, and for rangeland and forestry management29.

Non-governmental organizations can also partner to create groundwater management programs that offer education, technical assistance, monitoring services, and outline voluntary steps to reduce water contamination risks, for example the Michigan Water Stewardship Program30.
