This study investigates the synthesis and application of hydroxyapatite (HAp)-modified zeolite materials for efficient fluoride removal from groundwater-based drinking water. Characterization confirmed successful incorporation HAp onto surface formation a stable composite. EDS analysis revealed presence Ca P after modification, while FTIR XRD structural integrity during adsorption. ZH8 exhibited highest F-removal efficiency 92.23% at pH 3, 30 °C, [F−] = 6 ppm dose 10 g/L. Meanwhile, HAp-modified showed high F-selectivity, competing ions had limited interference. The Langmuir model best described adsorption process, suggesting monolayer with maximum capacity 39.38 mg/g ZH8. process followed pseudo-first-order kinetics, equilibrium achieved within 4 h. Regeneration studies demonstrated that maintained over 85% three cycles, highlighting its reusability. Column validated material’s practical applicability, breakthrough times up to 23 h under optimal conditions (flow rate: 8 cm3 min−1, bed depth: cm, feed concentration: 7.5 ppm) yield 99% 5 Vb 10.8 L. Thomas column indicating chemical as dominant mechanism. These findings demonstrate potential zeolite, particularly ZH8, an effective adsorbent in real-world applications.

Groundwater is one of the major sources freshwater supply for drinking and domestic purposes. This study evaluates hydrogeochemical processes, groundwater quality human consumption, associated health risks from fluoride F− nitrate (NO3−), dissolved solutes in a highland watershed northern Pakistan. samples (n = 51) were gathered analyzed range physicochemical parameters. To evaluate contamination, indices such as pollution index (NPI) (FPI) applied, along with composite to assess overall water quality. The findings revealed that total solid, turbidity, F−, K+ levels exceeded health-based thresholds 20%, 1%, 4%, 2% samples, respectively. Among sources, handpumps identified most contaminated. According NPI index, 96% 92% did not show significant However, FPI results highlighted 59% exhibited low pollution, while 41% fell under medium levels. While NO3− ingestion posed no notable risks, exposure presented concerns, 58.8% posing particularly children. dominant hydrochemical facies Ca-Mg-HCO3, main influence on chemistry by rock-water interactions reverse ion exchange processes.
