Background of the Study:
Water contamination is a pressing environmental health concern that significantly affects public health outcomes, particularly in regions with inadequate water treatment and sanitation facilities. In Kaduna State, a combination of industrial discharges, agricultural runoff, and poor waste management practices has led to the contamination of water sources with harmful pathogens, chemicals, and heavy metals. These contaminants have been directly linked to outbreaks of diarrheal diseases, which remain one of the leading causes of morbidity and mortality, especially among children under five years of age (Usman, 2023).
The contamination of water supplies in Kaduna State poses a serious risk to communities that rely on untreated or poorly treated water for drinking, cooking, and personal hygiene. Microbial pathogens such as Escherichia coli, Vibrio cholerae, and other enteric bacteria thrive in contaminated water and are known to cause severe gastrointestinal infections. Additionally, chemical pollutants such as nitrates and heavy metals can exacerbate the health risks by affecting the immune system and increasing susceptibility to infections (Aliyu, 2024). Seasonal variations and climatic factors further complicate the situation, as periods of heavy rainfall often lead to increased runoff and a higher likelihood of waterborne disease outbreaks.
The socio-economic impact of water contamination extends beyond health, affecting education, productivity, and overall community well-being. Families frequently bear the financial burden of medical treatment and lost income due to illness. Despite various government and non-governmental initiatives aimed at improving water quality and sanitation, challenges persist in implementing sustainable solutions across Kaduna State. There is a critical need to evaluate the direct impact of water contamination on diarrheal diseases and to develop targeted interventions that can reduce disease incidence and improve water quality (Bello, 2025). This study aims to bridge the gap by providing an in-depth analysis of the relationship between water quality and the prevalence of diarrheal diseases in the region, thereby informing policy and public health strategies.
Statement of the Problem :
In Kaduna State, water contamination remains a critical environmental and public health issue that directly contributes to the high incidence of diarrheal diseases. Despite efforts to improve water treatment and sanitation, many communities continue to rely on water sources that are heavily contaminated with microbial pathogens and chemical pollutants. The lack of effective water quality monitoring and enforcement of environmental regulations exacerbates the problem, leading to frequent outbreaks of diarrheal illnesses that disproportionately affect children and vulnerable populations (Gambo, 2024).
The persistent problem of water contamination is compounded by infrastructural deficits, limited public awareness, and socio-economic constraints. Rural and peri-urban areas in Kaduna State are particularly affected, where access to safe and clean water is limited, and the available water is often sourced from contaminated rivers, wells, or boreholes. This situation not only contributes to immediate health risks but also has long-term implications on community health, economic productivity, and social development. The financial burden associated with treating diarrheal diseases, coupled with lost educational and workdays, creates a cycle of poverty and poor health outcomes (Sani, 2025).
Furthermore, existing studies on water contamination and its health effects have largely focused on urban centers, leaving a significant gap in our understanding of its impact in more vulnerable rural settings. The limited scope of current research hinders the development of comprehensive policies that address the root causes of water contamination and its health consequences. This study seeks to systematically assess the impact of water contamination on diarrheal diseases in Kaduna State, identify the primary sources of contamination, and propose sustainable interventions to mitigate these health risks.
