Abstract: The presence of cations–anions in water is the cause of mineralization in groundwater. Such water is highly saline when it comes in contact with natural mineralized rocks and ores beneath the perched water bodies. Due to the continuous pumping of water from these aquifers, the salinity of water increases. Parameters like flow hydraulics and water chemistry were studied using three sets of columns and the tracer test is assessed for the ingestion effect on porous materials. Even though several transport models have been developed in recent decades, here focus is on developing salt ingestion in two conditions, namely biotic and abiotic. Salt ions in the column reflect that ingestions are higher in the biotic columns than in the abiotic, the preferable reactive sites allowed the salts to transport and leached according to a high flow rate. It suggests that salinity in water is caused on account of the hydraulic conditions in the water-bearing zone. Further study is expected to narrow the hydraulics and water chemistry understanding on the influence of sizes of packing material, flow velocity of the water, and intra-ionic competition of the ions during the transport of salts in contribution to salinity.
