Abstract: A livestock and poultry farm in Neixiang County, Nanyang City was chosen as the research object and a total of 11 groundwater samples were collected in its surrounding areas. The test indicators included 35 conventional indicators and 24 antibiotic indicators. Water chemical analysis, groundwater quality assessment, pollution assessment and health risk assessment were carried out by using mathematical statistics, Piper diagram, correlation analysis, pollution index method and health risk assessment model. The results showed that the characteristic pollution factors of groundwater around the farm included total hardness, nitrate, lead, iron and manganese. The antibiotic components with relatively high concentrations were josamycin, lincomycin, norfloxacin, danofloxacin and flumequine, among which lincomycin had the highest pollution risk. The health risk assessment showed that the non-carcinogenic risk was mainly caused by oral intake of nitrate nitrogen and lead, and the maximum non-carcinogenic health risk index reached 0.908 and 0.875, respectively, which was close to the risk threshold. Finally, the causes of pollution were analyzed based on the geological conditions and human factors of the study area.
