The hidden impact of seafood processing on coastal aquifers: Hydrogeochemistry and water quality assessment.

Seafood processing industries play a crucial role in meeting global food demands; however, their consequences on groundwater quality are a growing concern. The study fills the existing knowledge gap among the shallow aquifers of the Southwest coast of India by conducting a thorough assessment of the hydrogeochemical alterations caused by the release of wastewater and waste by-products related to seafood processing operations. The methodology involves a multi-faceted approach, encompassing field sampling, hydro-chemical modelling, and statistical validation.

Seawater intrusion and resuspension of surface sediment control mercury (Hg) distribution and its bioavailability in water column of a monsoonal estuarine system.

There is limited knowledge regarding seawater intrusion on Hg distribution in monsoon fed tropical estuarine systems during dry season (February to May). This study examined the influence of resuspension of estuarine sediment and intrusion of Hg bound SPM (Hg) (by the tide) from the outside of an estuary in controlling distribution, mobility, and bioavailability of Hg within the estuarine systems during the dry season. This investigation was carried out in the Mandovi estuary, a monsoon fed tropical estuary from the central west coast of India.
