Potable Water Access and Its Impact on Nutrition and Health
This paper examines the relationship between access to potable water and nutritional outcomes, drawing on six peer-reviewed studies. It discusses how the absence of clean drinking water contributes to waterborne diseases such as cholera and diarrhea, which prevent the body from retaining essential nutrients and ultimately cause malnutrition. The paper addresses how poverty, inadequate waste management, and compromised water distribution systems compound these risks, particularly in low-income and rural communities. It also reviews interventions — including improved sanitation, community education, and borehole installation — that have demonstrated measurable reductions in malnutrition and child mortality when potable water is made reliably available.

What makes this paper effective
- The paper builds a clear causal chain — from unsafe water to disease to nutrient loss to malnutrition — making the argument easy to follow even across multiple studies.
- It grounds abstract public health claims in specific, real-world contexts (Kenyan slums, street food vendors, rural borehole access), giving concrete texture to statistical arguments.
- The paper moves logically from problem identification through mechanisms of harm to practical interventions, providing a complete analytical arc.
Key academic technique demonstrated
The paper demonstrates effective synthesis of a small literature review: rather than summarizing each source separately, it weaves multiple citations into a unified argument about how water quality, sanitation, and nutrition interact. This integrative approach — where sources reinforce and contextualize one another — is a core skill in public health and social science writing.
Structure breakdown
The paper opens with an introduction establishing the water–nutrition link and previewing the six reviewed studies. It then moves through nutritional deficiency mechanisms, sanitation and waste management failures, and disease-driven nutrient loss, before shifting to the documented benefits of potable water access. A brief conclusion restates the central argument and offers policy-facing recommendations. The structure follows a classic problem–mechanism–solution format suited to applied health research writing.
Introduction
There is a direct correlation between the lack of clean, safe water for drinking and cooking and nutritional problems. The lack of clean drinking water leads to diseases like diarrhea, and nutritional deficiencies are directly related to the absence of potable water. This is because a person does not receive enough calories, proteins, carbohydrates, vitamins, or minerals. Undernutrition has been associated with 45 percent of global deaths, and nearly 7.4 percent of the world's children are at risk of undernutrition. Malnourished children have weakened immune systems that make them more susceptible to diarrhea when they are exposed to dirty water. The lack of clean water means that individuals are living in unsanitary environments, which increases the risk of diarrhea. People suffering from diarrhea eat less and are unable to absorb the nutrients they need from the food they consume, resulting in malnutrition. As Esrey and Habicht (1986) note, diarrhea can occur after a person ingests contaminated water. There are also instances when water containing low doses of pathogenic bacteria — sufficient to infect humans — is used to prepare food, which can incubate and multiply the bacteria in that food (Esrey & Habicht, 1986).
Numerous studies have been conducted indicating that the lack of clean water has adverse effects on individual nutrition. The underlying trend across six reviewed studies is that the absence of clean drinking water has been consistently associated with nutritional problems. Low-income areas are disproportionately affected, and the lack of proper waste disposal has also been linked to nutritional issues. According to Moe and Rheingans (2006), the provision of clean water is one of the primary means of preventing the spread of waterborne disease. However, they also note that the distribution system itself can be problematic and can result in water contamination. Therefore, there must be mechanisms to ensure that clean piped water is delivered to individual homes without contamination during distribution, as distribution system contamination has been identified as the single most common cause of outbreaks in community water systems.
This paper aims to determine the effect of potable water on nutrition. To this end, six articles focusing on the role of potable water in nutrition have been reviewed, with some also addressing sanitation. The paper begins with the nutritional problems that arise when clean water is unavailable for drinking and food preparation, then progresses to interventions that have been put in place to address these problems, and finally considers strategies that can be implemented in areas where water is scarce.
