Groundwater quality is a critical factor in the sustainable management of groundwater resources, especially in densely populated regions prone to contamination from anthropogenic activities and seawater intrusion. This study investigates the groundwater quality dynamics in the coastal zones of Kannur district, Kerala, India, employing a geochemical perspective. Groundwater samples for 21 locations on the Kannur coast were collected from the Central Groundwater Board (CGWB) with additions from the Kerala State Groundwater Board. This study employs an integrated approach using Piper, Schoeller, and Stiff diagrams along with statistical analyses to assess the groundwater quality dynamics. The results reveal significant spatial variability influenced by seawater intrusion, carbonate weathering, and anthropogenic activities. Piper, Schoeller, and Stiff diagrams indicate the dominance of Ca²⁺-HCO₃⁻ and Na⁺-Cl⁻ water types, reflecting a mix of fresh and saline water. Seawater intrusion and anthropogenic impacts are prominent near the coastline. The findings highlight the need for sustainable groundwater management strategies, including monitoring salinity intrusion and controlling pollution sources, to ensure long-term water quality and availability.
