Devarakonda, located 50 kilometers west of Nalgonda, is a peninsular gneissic complex with a lot of agricultural activity and past increasing urbanization. Major ions pH, EC, TDS, Ca, Mg, TH, Na, K, CO3, HCO3, Cl, NO3, SO4, and F were all measured in 45 pre-monsoon samples. During the pre-and post-monsoon seasons, fluoride concentrations range from 0.36 to 3.11 mg/l and 0.25 to 2.56 mg/l, respectively. The presence of fluoride ions in groundwater samples affected the samples, according to the findings. When compared to the World Health Organization's tolerance limit (1.5 mg/l), about 51% and 36% of groundwater samples had higher fluoride levels. The piper trilinear found that Na-Ca-Cl and mixed Ca-Mg-Cl were the most common groundwater types. The majority of the area is a rock dominant field, according to Gibb's plot. The study region's water chemistry is dominated by weathering of feldspar minerals and cation exchange reactions, according to statistical analysis. According to the principal component analysis majorly groundwater samples are influenced by weathering of silicate group minerals and cation exchange processes, and anthropogenic contribute to groundwater chemistry.
