Human Impact: Water And Pollution In Argentina

Water pollution is a significant issue in Argentina, with industrial effluents, stormwater, flooding, and groundwater management posing major concerns, particularly in the greater Buenos Aires region. The country's most polluted river, the Reconquista, is a stark example of the ecological challenges faced by Argentina, as it carries cow hides, animal organs, heavy metals, and diseases into the Parana River. While there have been efforts to address pollution, such as a local judge shutting down factories and jailing executives for dumping poisons, Argentina continues to struggle with effectively tackling its pollution problems. Deforestation, soil degradation, desertification, air pollution, and water pollution are also prevalent, threatening the country's biodiversity and landscapes. Sanitation has been an ongoing issue, with low-income and rural areas lacking access to clean drinking water, and water consumption in Argentina being among the highest in the world.

Water pollution from industrial effluents

The problem of industrial effluents extends beyond the Matanza-Riachuelo River Basin. In the city of Mendoza, for instance, agriculture and industrial runoff, along with the mismanagement of irrigation water, have deteriorated the first levels of the aquifer. This has resulted in over-pumping and the exploitation of deeper wells, leading to a risk of vertical filtration where contaminated water from higher levels can infiltrate lower water tables.

The abandonment of older wells without proper sealing further exacerbates the issue, causing fields to become stagnant and barren, resulting in economic losses for the region. Additionally, lakes and reservoirs in Argentina are facing water quality issues due to various factors, including industrial activities, deforestation, logging, animal production, and the discharge of untreated sewage.

The discharge of industrial effluents into water systems is a primary source of water pollution in Argentina. This, coupled with improper landfill techniques, flooding in urban areas, and agricultural practices, has led to a decline in water quality and the contamination of freshwater sources.

To address these challenges, Argentina has implemented various measures, including the creation of institutions such as the National Institute for Water and the Environment (INA) and the National Water and Sanitation Utility (AySA). These organizations work towards researching, preserving, and developing water resources, as well as implementing water projects. However, more needs to be done to optimize the state's regulatory function and expand coverage to ensure sustainable water management in the country.

Fracking and oil leaks

One of the primary issues is water usage and contamination. Fracking requires large volumes of water, which can deplete local water resources, especially in arid regions like Patagonia. There are also worries about potential groundwater contamination from the chemicals used in fracking fluids. The management of wastewater produced during the extraction process is another concern, as it can contain hazardous substances such as heavy metals, salts, toxic hydrocarbons, and radioactive materials.

In 2019, Greenpeace activists brought attention to the issue by blockading the entrance to a toxic waste facility in Patagonia. They highlighted how waste from fracking operations by oil companies, including Shell and Total, had been illegally dumped near a residential area and a major water supply. The landfill site was found to be in violation of local regulations, as it was too close to both people and bodies of water. Natalia Machain, Executive Director of Greenpeace Argentina, warned that the toxic waste from fracking could poison waterways and make children sick, while also pushing the global climate closer to irreversible catastrophe.

The impact of fracking on water pollution in Argentina is not limited to Patagonia. The country's energy sector, including the development of unconventional oil and gas resources, contributes significantly to its greenhouse gas emissions. This has raised concerns about Argentina's ability to meet its climate commitments under the Paris Agreement. Additionally, there are worries about seismic activity induced by fracking and the injection of wastewater into deep wells, particularly in areas near the Andes mountain range.

Overall, fracking and oil leaks have had a detrimental effect on water pollution in Argentina. The country faces the challenge of balancing energy production with sustainability and climate goals, addressing the environmental and health concerns associated with these practices.

Lack of access to clean drinking water

Despite Argentina's large water resources, the country faces significant challenges in providing access to clean drinking water for its population. While the situation has improved in recent years, with 99% of the population gaining access to "special" water in 2015, disparities remain, particularly between urban and rural areas.

In urban areas, water services are generally continuous and of potable quality. However, issues such as water rationing and sub-standard drinking water quality persist in some cities during the summer months. The situation is more acute in rural areas, where only 98.9% of the population had access to "special" water in 2015, compared to 99.9% in urban areas.

One of the main issues affecting access to clean drinking water in Argentina is the lack of infrastructure. In the province of Chaco, for example, infrastructure works have focused on ensuring a constant supply of safe water, with the Wichi System benefiting 25,000 people in some of the most vulnerable and isolated communities. However, across the country, 21% of the total population remains without access to house connections, and 52% of the urban population lacks access to sewerage. This disparity in access to basic water and sanitation services is particularly pronounced in the poorest provinces and areas.

The responsibility for operating and maintaining water and sanitation services in Argentina falls on provincial water and sewer companies, municipalities, and cooperatives. However, these entities often struggle to recover operation and maintenance costs, and the freezing of tariffs since the 2002 economic crisis has further eroded their financial capacity. As a result, they heavily rely on federal transfers and specific sector programs for investment financing. The highly decentralized nature of the country's governance structure and the dispersion of sector responsibilities between various levels of government also hinder the development of a coherent national water policy, which further exacerbates the challenges in ensuring universal access to clean drinking water.

Moreover, water pollution poses a significant threat to the availability of clean drinking water in Argentina. Industrial effluents, stormwater, flooding, and groundwater management are major concerns, particularly in the greater Buenos Aires area. In addition, agricultural activities, deforestation, logging, animal production, mining activities, and urban runoff contribute to the deterioration of water quality in lakes and reservoirs across the country. The lack of proper sewage systems and the discharge of untreated sewage further exacerbate water pollution levels, leading to health issues such as acute gastrointestinal diseases, paratyphoid, typhoid fever, and intestinal parasitosis.

Deforestation and pollution

The main cause of deforestation in Argentina is the growth of the agricultural industry, particularly for intensive livestock farming and soybean production. Argentina is the third-largest soybean producer in the world, and much of the country's farmland has been converted for soybean cultivation. Research shows that soybean production was a direct driver of deforestation in the 2000s. As soybean producers rushed to meet global demand, they began clearing forests and arid regions to find new land for cultivation. Technological advancements also made it easier to grow crops on these previously untapped marginal lands.

The expansion of cattle breeding and beef production has also contributed to deforestation in Argentina. These activities have threatened grasslands and forests, particularly in the Chaco ecoregion and the Espinal Ecoregion. The Chaco ecoregion, located in northern Argentina, is the second-largest dry forest in South America. It spans about 650,000 square kilometers (250,000 square miles) across Argentina, Paraguay, Bolivia, and Brazil. The Chaco is home to thousands of plant species and hundreds of animal species, and it has been facing rapid deforestation in recent years.

Observations by Landsat satellites indicate that approximately 20% of the Chaco forest, or 142,000 square kilometers, was converted into farmland or grazing land from 1985 to 2013. Between 2010 and 2018, more than 29,000 square kilometers of the Chaco were cleared for farms and ranches, with much of the clearing taking place in Argentina. This rapid deforestation has had significant ecological consequences, intensifying the impacts of climate change and leading to extreme weather events, species extinction, displacement of native and Indigenous communities, and adverse effects on human health.

To address deforestation, Argentina enacted a national "forest law" in 2007, mandating that local governments regulate large-scale farming expansion and establish practices to protect native forests. However, research suggests that local governments have struggled to enforce this law effectively, and certain protected zones have continued to experience deforestation.

Inefficient use of non-renewable resources

The electricity sector in Argentina is facing challenges due to rising demand and declining reserve margins. The country's electricity demand has been steadily increasing, with an annual growth rate of over 6%. To meet this rising demand, the government is commissioning large projects in generation and transmission, requiring significant investments. However, the electricity sector is highly dependent on natural gas, which faces uncertainty due to declining gas reserves and potential supply issues. This overreliance on a single source of energy contributes to inefficient use and makes the sector vulnerable to supply disruptions.

Another factor contributing to the inefficient use of non-renewable resources in Argentina is the structure of the electricity market. The market is highly regulated, with transmission and distribution sectors being less competitive than generation. The transmission sector, in particular, is dominated by a few private companies, which may limit innovation and efficient resource utilisation. Additionally, cross-ownership restrictions between generation, transmission, and distribution segments may hinder the optimal utilisation of resources.

Argentina has recognised the need to diversify its energy mix and promote renewable energy sources. The country has set a goal for non-hydro renewables to reach 20% of the power mix by 2025. However, the development of renewable energy projects faces challenges due to limited transmission and transformation capacity. The government has estimated that significant investments are required to expand and upgrade the transmission and transformation infrastructure to support the integration of renewable energy sources.

The inefficient use of non-renewable resources in Argentina has economic and environmental implications. The heavy reliance on natural gas and oil contributes to higher energy costs and increases the country's carbon footprint. Additionally, the lack of diversification in the energy mix makes the country vulnerable to fluctuations in global energy markets and supply chain disruptions.

To address these issues, Argentina should focus on several key strategies. Firstly, the country should continue to prioritise the development of renewable energy sources, such as wind, solar, and hydropower. This will help reduce the overreliance on natural gas and oil, improving efficiency and sustainability. Secondly, the government should work on removing barriers to the integration of renewable energy, including investing in transmission and transformation infrastructure. This will enable a more diverse and resilient energy mix. Finally, Argentina should consider further reforms to increase competition and efficiency in the electricity market, particularly in the transmission and distribution sectors.
