Ghana's water resources are being polluted by a variety of factors, including illegal mining, inappropriate use of agrochemicals, sewage discharge, and plastic waste. The quality of water in Ghana has deteriorated due to these polluting activities, causing health issues for the population and negatively impacting the environment. In particular, the practice of galamsey, or illegal artisanal mining, has been associated with significant environmental impacts, including the destruction of aquatic ecosystems. The Ghanaian government is working towards improving water quality by 2030, addressing the critical sources of pollution and mitigating their impacts on human health and the environment. However, the existing water management strategies are not sufficient to address the challenges posed by the constant exploitation of water resources and the rapid population growth in the country.

What You'll Learn
Illegal mining and agrochemicals
Ghana's water resources are being polluted by a variety of sources, including illegal mining and the inappropriate use of agrochemicals.
Illegal Mining
Also known as "galamsey", illegal mining has been widely associated with significant environmental impacts, including the destruction of aquatic ecosystems. This practice involves the use of simple tools to mine gold, which is then sold. While it provides socio-economic benefits, it has led to the pollution and destruction of water bodies and the degradation of farmlands. The advent of earth-moving equipment in small-scale mining has increased surface water pollution throughout the country.
The majority of miners in Ghana work informally, without licenses, due to challenges with securing land and permits. This informality has resulted in a number of environmental and social problems, including the negative health impacts of working in hazardous conditions.
Agrochemicals
The constant use of agrochemicals in agriculture contaminates freshwater bodies and the environment. The use of chemical fertilizers and pesticides in agriculture contributes to water pollution, as these chemicals leach into water systems. This is exacerbated by the inappropriate sanitation practices that are common in Ghana, such as open defecation.
The quality of water in Ghana has deteriorated due to these practices, with high levels of pH, Fe, P, and Pb found in water samples. This has led to an increase in water-related diseases, such as cholera, diarrhoea, dysentery, hepatitis A, typhoid, and polio. The government of Ghana is working to improve water quality by 2030, but the existing water management strategies are not robust enough to address the current challenges.

Poor sanitation
In Ghana, the primary sources of water for rural communities are small ponds and unprotected wells, which are highly susceptible to pollution. These water sources often contain parasites, high levels of microbes, and dangerous minerals, posing serious health risks to those who consume it. The consumption of contaminated drinking water has been linked to various water-related diseases, including cholera, diarrhoea, dysentery, hepatitis A, typhoid, and polio. The situation is further exacerbated by the practice of open defecation, with 23% of Ghana's population relying on it as their primary means of sanitation.
The inadequate management of wastewater from urban, industrial, and agricultural activities further contributes to water pollution in Ghana. Only a small proportion of the substantial amount of wastewater generated in urban areas is collected and treated, resulting in the contamination of drinking water sources for millions of people. This issue is prominent in the capital city of Accra, where approximately only 10% of wastewater is collected. Additionally, the ineffectiveness of treatment plants is concerning, with less than 25% of the 46 industrial and municipal treatment plants in Ghana being functional, according to a 2001 inventory.
The use of surface water sources, such as rivers, dams, and lakes, further exacerbates the sanitation challenges in Ghana. These water sources are highly likely to be polluted with bacteria and toxic products, leading to infections and diseases, including deadly ones. The lack of reliable and hygienic water sources forces households to rely on alternative options, often at a higher cost. The widespread use of plastic drinking water sachets, due to the lack of available potable water, has contributed to increased plastic pollution, further contaminating water bodies.
While Ghana has made efforts to address water quality issues, the existing water management strategies have struggled to keep up with the challenges posed by increasing pollution levels and rapid population growth. The government and its partners have made significant strides, yet approximately 76% of households remain at risk of consuming water contaminated with animal and human excreta. The path towards improving water quality by 2030, as stated by Ing Harold Esseku, a Senior Water and Sanitation Specialist at the World Bank, underscores the urgency and ongoing work to tackle sanitation issues in Ghana.

Plastic pollution
Ghana generates over 3,000 metric tons of plastic waste every day, which amounts to 1.1 million metric tons per year. An estimated 86% of this plastic waste is mismanaged, leading to widespread environmental and urban pollution. This has become a common issue in almost every community in Ghana over the past 20 years, contributing to disasters such as flooding and cholera outbreaks.
The widespread use of plastic drinking water sachets, due to the lack of available potable water, has led to increased plastic pollution in Ghana. This plastic pollution often ends up polluting water bodies, further contaminating the limited drinking water sources available.
In addition to plastic pollution, other major causes of freshwater pollution in Ghana include illegal artisanal mining, known as "galamsey", localized discharges of sewage into water bodies from industrial and domestic activities, and the leaching of fertilizers and pesticides used in agriculture. The constant use of agrochemicals in agriculture contaminates freshwater bodies and the environment.
The quality of groundwater and surface water resources in Ghana is worsening due to various factors, including pollution from illegal mining, waste, leachate from chemical fertilizers and pesticides, and rapid population growth. The existing water management strategies are not robust enough to address these challenges, and the per capita availability of water resources is decreasing daily.
While Ghana has made strides in improving water quality, such as through the use of boreholes, the issue of plastic pollution remains a significant contributor to the overall water pollution challenge in the country.

Industrial and domestic sewage
Ghana's water resources are under threat from various sources of pollution, one of the most significant being industrial and domestic sewage. The discharge of sewage into water bodies from industrial and domestic activities is a major contributor to water pollution in Ghana. This includes both legal and illegal discharges, with industrial effluents and toxic substances ending up in water systems.
The problem is exacerbated by the inadequate management of wastewater. In urban areas, such as the capital city of Accra, only a small portion of the generated wastewater is collected and treated, leading to the contamination of drinking water for millions of people. This is a serious health hazard, as the water can be chemically polluted or contain dangerous bacteria.
The main sources of water for rural communities in Ghana, such as small ponds and unprotected wells, are easily polluted, causing diseases in those who consume the water. These water sources often contain parasites, high microbial content, and dangerous minerals. The use of boreholes for drinking water has reduced reliance on rivers, but surface water sources remain critical for crop production and other domestic uses.
In addition to industrial and domestic sewage, other sources of water pollution in Ghana include agrochemicals from agriculture, illegal mining activities, and population growth. The constant use of chemical fertilizers and pesticides, as well as the discharge of waste from mining operations, have severely impacted water quality. Ghana's water management strategies struggle to keep up with the rapid decline in water quality and quantity, and climate change further exacerbates these challenges.
To address these issues, Ghana has signed onto international agreements and treaties on health and pollution, and has developed various legal and policy frameworks to safeguard its citizens and the environment. However, the effectiveness of these measures remains to be seen, and the country continues to face significant challenges in providing clean and safe water to its population.

Fertilisers and pesticides
Water pollution is a significant environmental challenge in Ghana, and the quality of its water resources is worsening due to soaring pollution levels. One of the major causes of freshwater pollution in Ghana is the leaching of fertilisers and pesticides used in agriculture.
The constant use of agrochemicals in agriculture contaminates freshwater bodies and the environment. In the dry season, irrigation farming relies heavily on agrochemicals, including fertilisers and pesticides, which can leach into the water supply. This intensive use of agrochemicals is a climate change adaptation strategy, but it comes at the cost of increased pollution risks.
The use of fertilisers and pesticides in agriculture is essential for increasing crop yields and ensuring food security. However, their inappropriate use can have detrimental effects on the environment and human health. Excessive or improper use of fertilisers and pesticides can lead to water pollution, soil degradation, and even air pollution. It can also negatively impact the health of farmers and nearby communities, as these chemicals can cause various health issues, including respiratory problems and skin irritation.
While Ghana has constitutional and policy frameworks in place to address pollution, the challenge of environmental pollution persists. The country has a high number of institutions dedicated to environmental management, but the institutional framework is incomplete and suffers from conflicting mandates and ambiguous relationships between agencies and ministries. This has impeded improvements to the country's environmental governance system and has contributed to the ongoing issue of water pollution from fertilisers and pesticides.
