Strengthen groundwater governance
Groundwater is the world's most abundant freshwater resource, regulating water extremes such as floods and droughts. However, it is often out of sight and out of mind, and the current approach to groundwater management is leading the world towards disaster, according to Dr John Cherry, winner of the 2020 Stockholm Water Prize.
Groundwater depletion and pollution can often be attributed to poor governance, stemming from a lack of knowledge about groundwater. Therefore, it is crucial to strengthen groundwater governance by making groundwater science more accessible and raising awareness about groundwater governance. Here are some ways to achieve this:
Firstly, promote ecological agriculture as a form of cradle-to-cradle production for food. This involves shifting away from modern chemical agriculture, which is a major cause of groundwater depletion and pollution. Impose taxes or penalties on agricultural activities that pollute groundwater and eliminate government subsidies that contribute to groundwater unsustainability.
Secondly, establish effective groundwater monitoring systems. Utilise modern, cost-effective methods such as real-time data recording technology to monitor groundwater levels and hydrochemistry. Ensure data transparency by making the information publicly available, enabling citizens to access the data on their smartphones or tablets.
Additionally, encourage cooperation between federal departments, states, and local governments to prevent and control groundwater pollution. The EPA can play a crucial role by providing guidance, technical assistance, and grants to support state planning and pollution control efforts. Implement the Pollution Prevention Act, which mandates the EPA to establish programs for preventing, reducing, or eliminating groundwater pollution and improving water quality.
Furthermore, raise awareness about the importance of groundwater protection among the public and engage them in the decision-making process. Educate citizens about the impact of human activities on groundwater and the environment, empowering them to make informed choices and support sustainable practices.
By implementing these measures, governments can strengthen groundwater governance and protect this vital resource for future generations.

Shift to ecological agriculture
Agriculture is the world's largest industry, employing over one billion people and generating over $1.3 trillion worth of food annually. As such, it has a significant environmental impact.
Firstly, agriculture requires large amounts of freshwater, consuming about 69% of the planet's supply. This can cause environmental pressures in water-stressed regions. Secondly, agriculture pollutes rivers, lakes, and oceans by releasing nutrients, causing eutrophication. Eutrophication accounts for 78% of global ocean and freshwater pollution. Thirdly, agriculture is a major driver of climate change, responsible for around a quarter of global greenhouse gas emissions. Finally, agriculture requires enormous land use, with half of the world's habitable land used for agricultural production. This has led to deforestation and the destruction of natural habitats, reducing the world's biodiversity.
To address these issues, a shift to ecological agriculture is necessary. Ecological agriculture is a form of cradle-to-cradle production applied to food, aiming to reduce groundwater depletion and pollution caused by modern chemical agriculture. Here are some ways in which this shift can be achieved:
- Improve groundwater governance: Groundwater depletion and pollution are often due to poor governance and a lack of knowledge about groundwater. Governments should implement effective groundwater monitoring methods and make data accessible to the public.
- Change food habits: Ecological agriculture encourages a shift away from eating beef and other animal-sourced foods. This is because livestock accounts for 94% of non-human mammal biomass, with poultry livestock outweighing wild birds by a factor of more than 3-to-1. Reducing the consumption of animal products can help alleviate the environmental impact of agriculture on land and water use.
- Financial incentives and taxes: Governments can create financial incentives to encourage biodiversity conservation and sustainable practices in agriculture. Additionally, imposing taxes or penalties on groundwater pollution caused by agricultural activities can deter unsustainable practices.
- Conservation and restoration of critical habitats: Sustainable agricultural practices can help preserve and restore critical habitats, protect watersheds, and improve soil health and water quality. This includes implementing conservation techniques, promoting the use of non-toxic substances, and reusing materials.
- Research and development: The EPA has been mandated to establish a national research and development program for pollution prevention and control. This includes providing grants to states and local agencies for pollution control and facilitating coordination among air pollution prevention and control agencies.
- Education and outreach: Making groundwater science more accessible through initiatives like the Groundwater Project can help raise awareness and capacity for groundwater governance.

Impose taxes on agricultural groundwater pollution
Groundwater is the world's most abundant source of freshwater, regulating water extremes such as floods and droughts. However, due to its hidden nature, it often remains out of sight and out of mind, making it difficult to manage and protect.
Agricultural activities are a leading cause of groundwater pollution, with modern chemical agriculture contributing significantly to groundwater depletion and contamination. Nitrogen-based fertilisers, pesticides, and livestock manure are among the primary sources of pollution, as they can infiltrate water sources through runoff, infiltration, and irrigation return flows.
To address this issue, governments can consider imposing taxes or penalties on agricultural groundwater pollution. This approach has been proposed in Minnesota, where nitrate pollution from agricultural activities has contaminated drinking water sources. The tax revenue is intended to fund the cleanup of nitrate pollution and provide safe drinking water to communities, particularly prioritising mothers and infants.
While taxation may be a practical alternative to monitoring and mitigating pollution levels, it is essential to recognise that taxes should not be the sole solution. Instead, a comprehensive approach should be implemented, including improved governance, education, and the adoption of sustainable agricultural practices.
For example, the National Water Quality Initiative (NWQI) in the United States aims to address agricultural water quality issues by promoting practices such as contour strip cropping, which reduces erosion and runoff. Additionally, nutrient management practices, such as targeted fertiliser and manure application, drip irrigation, and the storage of livestock manure in protected areas, can minimise runoff risks and improve water quality.
By combining taxation with a range of preventive and restorative measures, governments can effectively address agricultural groundwater pollution, ensuring the protection and sustainable utilisation of this vital resource.
