Issues raised during Public Hearings in respect of proposed Development Drilling activities in Godavari Onland and West Godavari PML blocks in the three districts viz.

Ministry of Environment and Forests b. Sri Mente (MOEF), made the observations that Someswara Rao, land subsidence has been reported Krishna Godavari and observed in the areas where Deltala Parirakshan extensive extraction of underground Samithi. water has been carried out. Oil and c. Sri. Gopala Krishna gas reservoirs have limited aerial Raju, Krishna extents and therefore not prone to Godavari Deltala subsidence. Parirakshan ONGC has outsourced the work to Samithi. investigate indications of Land Subsidence due to Hydrocarbon Exploration in KG-PG Basin to Delta Studies Institute, Andhra University. Notification of Award and Scope of Work for Hiring of Services to investigate indications of Land Subsidence due to Hydrocarbon Exploration in KG-PG Basin has been attached as Annexure F in this report 2 Intrusion of a. Sri. Gopala Krishna Groundwater salinity is not due to any Saline water in Raju, Krishna leakage of hydrocarbons and their agricultural fields Godavari Deltala associated produced water from the and ground water production wells. Production wells are Parirakshan constructed with many layers of casing Samithi. pipes with outer most one covering the b. Prof. G.Krishna shallow aquifers up to sufficient depths Rao, Retd. Prof. of and it protects the groundwater from Geology, Andhra any leakage effects. Ground water University contaminated wells are quite away Visakhapatnam. from the production wells. Even if there is contamination, it could be a local phenomenon and cannot be widespread as the aquifers are generally highly localized due to deltaic sedimentation pattern. Intrusion of seawater in the tube wells is due to over exploitation of groundwater. Seawater percolates into the inland parts from the seacoast. According to the Sub-committee‟s observations some studies have suggested extensive aquaculture could be a factor for groundwater salinity in the area. 3 Extracted gas is a.
