Being sensitive to environmental changes, for-aminifera have been extensively used to monitor pollution level in the marine environment, including the effect of mining in coastal areas. In the Goa state of India, the rejects from opencast mining on land largely find their way to the estuaries, as washout during monsoon.
According to the EIA report, open cast coal mining by proposed mine will involve breaching of the groundwater table. The depth of the groundwater table varies between 2.81 to 10.6 m below the ground level during the pre-monsoon period, and in post monsoon it ranges between 0.5 to 4.05 meter (page 3-14).

This study was carried out during the monsoon of 2002 which is the first rigorous study done in the wet-season to assess the impacts of mining and associated activities
Dust storms, or haboobs, are more common during the early part of the monsoon, but can occur at any time during the season, depending on rainfall patterns. Be prepared for blowing dust and reduced visibilities any time thunderstorms are nearby. Remember: PULL ASIDE, STAY ALIVE! If you encounter a dust storm, and cannot avoid driving into it.
