Horse Waste Linked to Surge in Waterborne Illnesses in Mahabaleshwar and Panchgani: Research Findings

Research uncovered that Venna Lake, the primary drinking water source for both Mahabaleshwar and Panchgani, was heavily polluted. The lake’s water was contaminated by equine waste from nearby recreational activities like horseback riding. This waste, especially during the rainy season, found its way into the lake, exacerbating the contamination problem.

To address these issues, the GIPE team, led by Dr. Priti Mastakar and supported by research assistants, undertook a comprehensive examination of water sources across the region, including the local water treatment plant. The results revealed high levels of contamination from E. coli and coliform bacteria, along with dangerous pathogens such as rotavirus and salmonella present in the equine waste.

Significant improvements have been made: the water treatment plant, which had been in disrepair for nine years, has been refurbished, and a new, effective water treatment system has been installed. According to Dr. Mastakar, “The water treatment plant, which was distributing contaminated drinking water, has been repaired and updated to ensure the water is now safe from both viruses and bacteria.”

Additionally, equine waste collection has been optimized, with the waste now being sent to biomethanation plants for energy production. This measure not only helps manage waste but also provides biogas for community kitchens. However, the plan to relocate the horse riding activities away from the lake area has yet to be fully realized.

The health improvements in Mahabaleshwar are reflected in the reduction of waterborne disease cases. Historical data showed a concerning rise in diarrhea cases, with peaks observed in May-June and November of 2022. The updated treatment and waste management practices have significantly reduced these health risks, particularly benefiting local residents and tourists.

The efforts of the GIPE, along with support from Satara District Collector Jitendra Dudhi and local officials, have brought substantial progress in enhancing the safety and quality of drinking water in Mahabaleshwar. Dr. Mastakar concludes, “Our research has significantly reduced health risks due to contaminated water, improving the safety of the local population and visitors alike.”
