Multi-component groundwater management programs include interventions to address soil and water quality. Such programs can 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), and water quotas and taxes.
Expected Beneficial Outcomes (Rated)
Increased use of water management practices
Improved water quality
Other Potential Beneficial Outcomes
Increased water conservation
Reduced soil erosion
Evidence of Effectiveness
There is some evidence that multi-component groundwater management programs increase use of best water management practices (Holsman 2002, Keestra 2012*), and improve water quality (Sahrawat 2010*, Kay 2009*, Kay 2012*, Esteban 2013*). However, additional evidence is needed to confirm effects, especially at the catchment level (Kay 2009*).
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 practices (Holsman 2002, Keestra 2012*). Soil and water conservation practices can reduce soil loss, as well as water, pesticide, and excess nutrient runoff (Sahrawat 2010*, Keestra 2012*), especially from individual plots and fields (Kay 2012*). 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 monitoring (Kay 2012*). Experts suggest that increased monitoring and regulation of these programs at the catchment level could improve their effectiveness (Sahrawat 2010*, King County DNR 2005, Kay 2012*).
Inconvenience, ignorance, and cost can be barriers to implementing groundwater management practices. Including educational materials and regulatory enforcement in multi-component programs may overcome such barriers (Kreutzwiser 2011*).
Impact on Disparities
There are a number of groundwater management programs in the US. Examples include state-level programs such as Florida’s Ground Water Program (FL DEP-GWP) and Minnesota’s Department of Natural Resources Groundwater Management Program (MN DNR-GMP); as well as regional or municipal programs such as the Sacramento Groundwater Authority’s Groundwater Management Plan (SGA-GMP), the Las Vegas Valley Groundwater Management Program (Las Vegas-GMP), and the King County Groundwater Protection Program in Washington (King County-GPP).
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 Program (MWSP).
