Cloud seeding is a form of weather modification, a way of changing the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud. The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice. Liquid propane, which expands into a gas, has also been used. Cloud seeding is used to increase precipitation in an area, to evaporate fog and clouds to keep an area dry by precipitating out, for reducing the cloud cover, to clean out the pollution, to help put out wildfire by making it rain. Cloud seeding has never been statistically proven to work but it is claimed to increase precipitation (Pelley, 2016). Since India is not very water rich, the cloud seeding technology is very closely associated with water resource management that is the major requirement for India. Under the guidelines of the Clean Water Act by the EPA, silver iodide is considered a hazardous substance, a priority pollutant and as a toxic pollutant. Chronic ingestion of iodides may produce skin rashes, running nose, headache and irritation of the mucous membranes.
