Water pollution from agricultural waste
Water pollution is a pressing issue in Costa Rica, threatening the quality of the country's abundant freshwater sources. While Costa Rica is known for its biodiversity and conservation efforts, water pollution from agricultural waste, industrial sewage, and inadequate wastewater treatment poses significant risks to both human health and the environment.
Agricultural development is a major contributor to water pollution in Costa Rica. The country's agricultural sector accounts for 6.5% of its GDP and employs 14% of its workforce. However, agricultural practices, such as the use of pesticides and other chemicals, can lead to water contamination. For example, in the agriculture sector, 70% of pollution comes from debris and waste generated by coffee plantations. This waste often ends up in waterways, contributing to surface water pollution.
In addition to chemical runoff, agricultural waste can also introduce bacteria into water sources. Dr. Thomas Shahady's research at the University of Lynchburg and the University of Georgia Costa Rica has revealed that several sites in the country are contaminated with bacteria such as E. coli, particularly during the wet season. This contamination is likely due to the inadequate collection and treatment of agricultural wastewater.
The government's lack of clear regulatory authority over wastewater treatment further exacerbates the issue. While the central government in San Jose and various government agencies are responsible for managing water quality, disparities in authority and unclear responsibilities have led to a lack of regulation and ineffective management of wastewater and greywater.
To address water pollution from agricultural waste, Costa Rica needs to implement multi-layered strategies. This includes adopting more stringent controls on contaminants, investing in water treatment infrastructure, and encouraging farmers to practice chemical-free agriculture. Community engagement and support for water monitoring practices are also crucial in ensuring the future of water health in the country.

Poor sewage treatment
One of the primary concerns is the inadequate collection and treatment of wastewater. Existing wastewater treatment plants are not well maintained, and the construction of new plants is costly. These plants often suffer from unrepairable structural damage and become blocked by sewage sludge build-up. The responsibility for water and sanitation is spread across multiple institutions, with a lack of coordination and conflicting competencies in policy planning and development. This fragmentation contributes to the ineffective management of water quality.
The fast population growth and urbanization in Costa Rica have further exacerbated the sewage problem. Overcrowded cities struggle with inadequate sewage systems, and in the most populated areas, only 19.4% of sewage receives treatment. The Tarcoles River, born in the central mountain range, is a stark example of the impact of poor sewage treatment. The Metropolitan Area of San Jose dumps 80% of its residues into this river, effectively using it as a city sewer and causing severe water pollution.
Agricultural waste and septic tanks also contribute significantly to water pollution. Septic tanks can contaminate aquifers, which serve as water supply sources, and the sludge removed during cleaning is often disposed of in rivers, further polluting water sources. Additionally, the use of pesticides on pineapple plantations has affected the quality of drinking water in some communities, such as in Siquirres, where residents have been dependent on water supplied by tanker trucks since 2007.
Community health is directly impacted by poor sewage treatment and water pollution. Dr. Thomas Shahady's research team found that several sites they tested were contaminated with bacteria, particularly during the wet season, likely due to inadequate wastewater treatment. The lack of access to reliable drinking water sources burdens healthcare systems, and there is a recognized need to improve water quality to reduce disease occurrences.

Industrial waste
While Costa Rica is known for its environmental initiatives and eco-tourism, the country faces significant challenges when it comes to industrial waste and pollution. The most pressing issue is water pollution, which affects both rivers and coastal areas.
One of the main contributors to water pollution in Costa Rica is inadequate wastewater treatment. Despite having a good availability of potable water, the country struggles with the management of wastewater and greywater. This is due in part to a lack of clear regulatory authority and government responsibility, as well as the challenging terrain and seasonal rains that hinder effective monitoring and maintenance of treatment plants. The current wastewater treatment plants in Costa Rica are not well maintained, and future construction is very expensive. Additionally, there is a lack of specific legislation or government programmes directly assigned to protect rivers from industrial and human waste.
Agricultural waste is also a significant contributor to water pollution in Costa Rica. The use of pesticides and fertilisers in agriculture can contaminate water sources, and improper waste disposal practices can lead to pollution of rivers and other water bodies. The Tarcoles River, for example, has been described as the most contaminated river in Central America, with the Metropolitan Area of San Jose dumping 80% of its residues into it, according to the Ministry of Environment and Energy (MINAE).
Community initiatives and beach clean-up programmes have been instrumental in raising awareness about water pollution in Costa Rica and encouraging environmental stewardship among locals and tourists alike. These efforts have also brought attention to the problem of plastic pollution, with styrofoam waste being a particular concern due to its non-recyclable nature. While these initiatives are a positive step towards reducing pollution, more comprehensive solutions are needed to address the underlying issues of industrial waste and inadequate wastewater treatment in Costa Rica.

Car pollution
Costa Rica has a population of 5 million people and approximately 1.4 million cars. The average age of these vehicles is 16 years, which is a contributing factor to the country's emission problem. The transport sector is responsible for 66% of hydrocarbon consumption and 54% of carbon dioxide emissions in Costa Rica. The capital city, San Jose, is particularly affected by car pollution, with the health costs of air pollution from vehicles running into millions of dollars each year.
In recognition of this issue, the government has proposed initiatives to reduce emissions and promote sustainable practices. For example, Marcela Guerrero, a lawmaker from the governing Citizen Action Party, presented a bill to eliminate import duties on electric vehicles for five years and encourage the adoption of zero-emission cars. The goal is to replace 100,000 conventional cars with electric alternatives. Additionally, there are plans to introduce an urban electric train system in San Jose to alleviate congestion and reduce emissions.
Costa Rica's commitment to clean energy is evident, with expectations to generate 97% of its energy from renewable sources, including hydroelectric dams, wind, solar, geothermal, and biomass energy. The nation aims to eventually reach 100% renewable energy, but this will require a balanced approach to energy production over many years.
While Costa Rica faces challenges in reducing car pollution, the government and citizens are taking active steps toward a more sustainable future. By encouraging the use of electric vehicles, investing in renewable energy sources, and developing sustainable transport infrastructure, Costa Rica is working towards lowering emissions and improving air quality for its citizens.

Water pollution in Costa Rica is a pressing issue, with the country's rivers, oceans, and groundwater systems being threatened by various sources of contamination. Agricultural runoff, including pesticide and fertiliser use, is a major contributor to water pollution. Industrial waste and sewage treatment facilities also play a significant role, with businesses discharging toxic materials and untreated waste seeping into water sources. The Tarcoles River, for example, has been heavily polluted by the Metropolitan Area of San Jose, which dumps 80% of its residues into the river, according to the Ministry of Environment and Energy (MINAE).
The government has recognised these water quality issues and has established more rigorous standards and management plans. However, enforcement of these laws and the provision of water and sanitation services to all households remain challenging. The physical terrain and seasonal rains further complicate effective water quality monitoring and management.
In addition to water pollution, Costa Rica also struggles with air pollution due to congested roads and ageing vehicles. The transport sector accounts for a significant portion of hydrocarbon consumption and carbon dioxide emissions, with old cars and buses spewing smoke. The country has nearly 1.4 million cars for a population of 5 million, and the average age of these vehicles is 16 years, exacerbating the emission problem.
To address these environmental concerns, Costa Rica has taken several initiatives. Lawmakers have proposed bills to encourage the adoption of electric vehicles and reduce import duties on them. Additionally, plans for an urban electric train system in the capital, San José, are underway, aiming to reduce congestion and emissions. Community initiatives, such as beach cleanups and educational platforms, also play a crucial role in raising awareness and promoting sustainable practices among locals and tourists.
