    Rapid consumerism and improper waste disposal create widespread environmental degradation through the air, water sources and landfills in India's rural areas. This work develops a health risk prediction model to score villages based on quantitative and qualitative factors. Quan-titative observations regarding pollutant levels and qualitative responses are collected at various households. The households are risk labelled against WHO standards. From the qualitative factors, significant factors are found. The health risk model is designed to correlate the qualitative factors. A total of 2,370 rural households spread across three dis tricts of Karnataka were selected. The study found that the health risk score predicted by the model has a higher significant correlation (>0.8) to various existing pollutant factors. The study found that source of drinking water (0.87), quality of drinking water (0.81), drainage canal availability (0.72), type of drainage (0.73), stagnant water (0.71), toilet availability (0.83), maintenance frequency (0.83), cooking fuel type (0.77), cigarette use (0.71), garbage pile up (0.73) and the percentage composition of wastes (0.74) were found to have a higher positive correlation to the health of rural households. The villages with higher health risks can be identified, and suitable mitigation plans can be designed to mitigate the health risk by state authorities.
