For site survey and quarrying impact analysis, Google Earth Pro was used to obtain satellite images. Impact of waste at the site and in nearby areas was studied by visiting the quarrying site in different seasons and at different times of the day. Impact on people living nearby and working at the site was evaluated by talking to the locals.
