The Impact of Waste Incineration on Water Quality: A Study of Naromoru Catholic Dispensary’s Incinerator and its Effects on Local Water Sources
Introduction
Waste incineration is a common practice in many healthcare facilities, including hospitals and dispensaries, as a means of disposing of medical waste. However, the process of incineration can have significant environmental implications, particularly on water quality. This study aims to investigate the impact of waste incineration on water quality, using the Naromoru Catholic Dispensary’s incinerator as a case study. The dispensary, located in a rural area of Kenya, has been in operation for over a decade and has been incinerating its medical waste on site. This study seeks to examine the effects of the incinerator on local water sources and to identify potential risks to human health and the environment.
Methodology
The study employed a combination of field observations, water sampling, and laboratory analysis to assess the impact of the incinerator on local water sources. Water samples were collected from nearby streams, rivers, and boreholes, as well as from the dispensary’s wastewater treatment plant. The samples were analyzed for various parameters, including pH, temperature, turbidity, and concentrations of heavy metals and other pollutants. Additionally, interviews were conducted with local residents and dispensary staff to gather information on the incineration process and any perceived impacts on the environment.
Results
The results of the study showed that the incinerator at Naromoru Catholic Dispensary was emitting significant amounts of pollutants, including particulate matter, carbon monoxide, and volatile organic compounds (VOCs). The water samples collected from nearby streams and rivers showed elevated levels of heavy metals, including lead, mercury, and cadmium, which are known to be toxic to humans and wildlife. The concentrations of these pollutants were found to be highest in the water samples collected closest to the incinerator, suggesting a direct link between the incineration process and water pollution.
The study also found that the dispensary’s wastewater treatment plant was not effectively removing pollutants from the wastewater, resulting in the release of contaminated water into the environment. The wastewater treatment plant was found to be inadequate, with insufficient capacity to handle the volume of wastewater generated by the dispensary.
Discussion
The findings of this study highlight the significant impacts of waste incineration on water quality. The emission of pollutants from the incinerator and the release of contaminated wastewater from the treatment plant pose significant risks to human health and the environment. The presence of heavy metals in the water samples is of particular concern, as these pollutants can accumulate in the food chain and cause long-term damage to ecosystems.
The study also highlights the need for improved waste management practices in healthcare facilities. The incineration of medical waste is a common practice, but it is not a sustainable or environmentally friendly solution. Alternative methods, such as recycling and composting, should be explored to reduce the amount of waste generated by healthcare facilities.

The impact of waste incineration on water quality is a significant concern, particularly in rural areas where access to clean water is already limited. The study of Naromoru Catholic Dispensary’s incinerator and its effects on local water sources highlights the need for improved waste management practices and more effective pollution control measures. The findings of this study have implications for policy and practice, and suggest that a more sustainable approach to waste management is needed to protect human health and the environment.
Recommendations
- Improve waste management practices: Healthcare facilities should explore alternative methods of waste disposal, such as recycling and composting, to reduce the amount of waste generated.
- Upgrade wastewater treatment plants: Wastewater treatment plants should be upgraded to ensure that they can effectively remove pollutants from wastewater.
- Implement pollution control measures: Pollution control measures, such as air pollution control devices and wastewater treatment systems, should be implemented to reduce the emission of pollutants from incinerators.
- Monitor water quality: Regular monitoring of water quality should be conducted to detect any changes in water quality and to identify potential risks to human health and the environment.
- Educate local communities: Local communities should be educated on the risks associated with waste incineration and the importance of proper waste management practices.
By implementing these recommendations, we can reduce the impact of waste incineration on water quality and protect human health and the environment.
