The study evaluated the effectiveness of a low-cost water disinfection technology called the Solar Water Disinfection (SODIS) method in rural India. The SODIS method involves filling transparent plastic bottles with water and exposing them to sunlight for several hours to kill harmful microorganisms.

The study found that the SODIS method was effective in reducing the presence of harmful bacteria in drinking water, with a 4.5 log reduction in bacterial counts after six hours of exposure to sunlight. However, the method was less effective in reducing the presence of viruses and parasites.

The study also found that the SODIS method was well-received by the community, with high levels of user satisfaction and willingness to continue using the technology. However, the study identified several barriers to adoption, including limited access to transparent plastic bottles and concerns about the taste and odor of treated water.
