Costa Rica has long been regarded as a global leader in sustainability, with a strong social conscience and commitment to ambitious environmental policies. However, the country faces significant challenges, particularly regarding water pollution and sanitation management. While Costa Rica has an adequate supply of drinking water, ineffective wastewater treatment, agricultural waste, and seasonal rains contribute to water pollution, impacting both river health and community health. To address these issues, researchers have developed innovative indices to increase community engagement and drive governmental action for improved water resource management. Additionally, Costa Rica has committed to long-term decarbonization goals, aiming for net-zero emissions by 2050 through sector-specific strategies, including transport electrification, renewable energy, and sustainable agriculture.

Water pollution
Agricultural development and pollutant runoff are also significant contributors to water pollution in Costa Rica. Pesticides and fungicides used in agriculture, such as chlorothalonil, have been detected in water sources, posing risks to human health. In the mountain town of Cipreses, for example, the local water source was found to be contaminated with chlorothalonil, a pesticide banned in Europe but still sold in Costa Rica. The authorities have been trucking clean water to the town, but the lack of systematic testing and the limited capabilities of the national authorities to test for certain pollutants raise concerns about the extent of the contamination.
In addition to agricultural pollution, septic tanks and inadequate sanitation management, particularly in rural areas, are also major contributors to water pollution in Costa Rica. Rivers carry high levels of pollutants and can be a significant source of disease. While potable water is available to over 99% of the population, wastewater treatment is highly lacking. The responsibility for water quality management is spread across multiple government agencies, leading to a lack of clear regulatory authority and ineffective governance of wastewater and greywater.
To address these issues, researchers have developed a simplified macroinvertebrate index that community groups can use to predict water contamination and make local decisions about how to deal with water pollution. This index has the potential to drive governmental agencies to react to water pollution and improve river and community health in Costa Rica. However, building and maintaining wastewater treatment plants is not a feasible solution, as current plants are already facing challenges with maintenance and the high costs of future construction.

Inadequate sanitation
One of the primary concerns is the inadequate collection and treatment of wastewater. The existing wastewater treatment plants are not effectively maintained, and constructing new ones is costly. The current infrastructure is often plagued by irreparable structural damage and frequent blockages due to sewage sludge buildup. This situation is exacerbated by the absence of a dedicated government agency, programme, or law specifically tasked with safeguarding rivers from the impacts of inadequate sanitation.
The sanitation sector in Costa Rica faces several key challenges. These include low sanitation connections, poor service quality, and low cost recovery. In 2015, around 274,000 people lacked access to "improved" sanitation, highlighting the extent of the issue. The majority of the population relies on septic tanks for sanitation, which, along with agricultural waste, contributes significantly to water pollution.
The country's unpredictable climate and vulnerability to natural disasters, such as the 2014-2016 El Niño-induced drought, pose significant obstacles to developing and maintaining water sanitation infrastructure. Additionally, the rapid population growth and urbanisation trends have further strained the already overburdened sewage systems, leading to inadequate sewage treatment in many cities.
To address these challenges, Costa Rica has embarked on various projects to improve sewage conditions and upgrade existing sewage plants. For example, the Administrations Associations of the Systems of the Aqueducts and Communal Sewers (ASADAS) play a pivotal role in constructing, monitoring, operating, and maintaining rural water aqueducts. These initiatives receive funding from both domestic and international sources, demonstrating a concerted effort to tackle the sanitation crisis.
While Costa Rica grapples with inadequate sanitation, it is reassuring to see that the country is actively pursuing solutions through community engagement, policy reforms, and collaborative projects. These efforts are vital to safeguarding the health and well-being of its citizens and preserving the country's precious water resources for future generations.

Air pollution
Costa Rica has demonstrated a commitment to mitigating short-lived climate pollutants and joined the Climate and Clean Air Coalition in 2017. The country has implemented initiatives to reduce black carbon from heavy-duty diesel vehicles and engines and to improve air quality and mitigate pollutant emissions from the municipal solid waste sector.
Costa Rica's 2015-2035 National Strategy for Low Carbon Livestock aims to scale up sustainable livestock agriculture practices. The Livestock Nationally Appropriate Mitigation Action (NAMA) project, launched in 2015, provides mechanisms to implement the strategy, resulting in a 70% reduction of greenhouse gas emissions on 141 farms. The project aims to expand to 27% of farms in the country by 2030.
Additionally, Costa Rica has worked with partners on projects in agriculture, waste management, and national planning to enhance policies and strategic plans to reduce short-lived climate pollutants. The country has also prioritised the health and productivity of employees by implementing air quality monitoring solutions in workplaces.

Climate neutrality
Costa Rica has launched a plan to achieve "
The transport sector is currently the largest single source of Costa Rica's climate-changing emissions, accounting for about 40%-50% of the country's net emissions. To address this, the government plans to modernize public transport, including the creation of an electric train line that will connect 15 neighbourhoods in the San José metropolitan area. By 2040, the number of cars circulating in urban areas is planned to be cut by half, and by 2035, 70% of the country's buses and 25% of its cars will be electric.
The agricultural sector is also a notable contributor to Costa Rica's emissions. To address this, the government has implemented a biofuel mandate, requiring gas stations to incorporate 10% ethanol into their gasoline. Additionally, Costa Rica is working to enhance carbon sinks, such as its forests, which play a crucial role in achieving its carbon neutrality goal.
Despite these positive developments, there are challenges and uncertainties surrounding Costa Rica's path to climate neutrality. For example, the current administration has paused or downscaled some key electric public transportation projects, and President Chaves has announced his intention to explore the country's fossil fuel reserves. There are also concerns about the long-term health of Costa Rica's forests, which are being relied on for carbon sequestration.
Overall, Costa Rica's efforts towards climate neutrality are a step in the right direction, and if successful, they could serve as a model for other nations.

Wastewater treatment
The responsibility for water and sanitation services in Costa Rica is spread across numerous institutions, including the Costa Rican Water and Sanitation Institute (AyA), which serves 46% of the population, mostly in urban areas. However, due to unclear regulatory authority and a lack of coordination between agencies, wastewater treatment remains largely unregulated. The physical terrain and seasonal rains also hinder effective water quality management.
To address these issues, Costa Rica has taken several steps. In 2006, the country signed the Metropolitan San José Environment Improvement Project loan with the Japanese Bank for International Development (JBIC) to finance a wastewater treatment plant, sewerage installation, and consulting services. As of 2011, bidding was underway for this large wastewater treatment plant for the metropolitan area of San José with Japanese financing. Additionally, Costa Rica has adopted the new Law for Integrated Water Resources Management (IWRM), which will incorporate innovative mechanisms for wastewater treatment and reuse, climate change mitigation, and natural ecosystem conservation.
Despite these efforts, there are still challenges. Building and maintaining wastewater treatment plants is expensive, and the existing ones are not well maintained, often suffering from structural damage and sewage sludge blockages. Furthermore, there is a lack of specific government initiatives to protect rivers from inadequate sanitation, despite evidence that improved water quality leads to better health outcomes.
