Question

Sea water intrusions consists of a lot of Geo-chemical process, which of the following is not included in the same?

(a) Inter-aquifer mixing

(b) Anthropogenic contamination

(c) Increasing dissolved oxygen

(d) Mobilization of brines

I had been asked this question during a job interview.

Question is taken from Management of Coastal Saline Soil topic in division Management and Remediation of Problem Soil of Environmental Biotechnology

Answer 1

Right choice is (c) Increasing dissolved oxygen

To elaborate: Sea water intrusions can be direct into aquifers or it is a combination of processes that consists of a lot of Geo-chemical processes like Inter-aquifer mixing, Anthropogenic contamination, water-rock interaction and Mobilization of brines, whereas, increasing the dissolved oxygen doesnot lead to soil salinity.
