Agricultural pollution is pollution caused by byproducts that come from fertilizers that are not suitable for plant needs, one of which is nitrogen. This study aims to examine the health risks of nitrite contamination (NO2) in dug well water in the agricultural area of ​​Cilacap Regency. This type of research used quantitative descriptive survey with cross-sectional design. The subjects studied were 103 people from the community living around the agricultural area who met predetermined criteria. The object of the research was 17 wells dug ≤ 150 meters from the rice fields and used as a source of drinking water. Data were collected by observation and questionnaires, then analyzed by calculating the ARKL formula. The results showed that the average nitrite concentration value was 0.03 (mg / L), the maximum nitrite concentration value was 0.22 (mg / L) and the minimum nitrite concentration value was 0.005 (mg / L). There is one well-dug location with nitrite concentration exceeding the threshold value of 0.220 mg / l. The results of the non-carcinogenic health risk analysis of nitrite exposure showed that the risk factor (RQ) of the entire test sample was <1, meaning that no risk caused a public health problem. It is provided that there is exposure to nitrite in water from dug wells of farmers who live near the rice fields, but this exposure has not caused any public health problems.
