The study examined the impact of pollution on groundwater quality in Onitsha Metropolis, Anambra State, Southeastern Nigeria. The specific objectives are to; examine the effect of air pollution on groundwater quality and assess the effect of land pollution on groundwater quality in Onitsha Metropolis. Arsenic levels in water samples from Onitsha were found using the atomic absorption spectrometry method. Water and soil samples were evaluated to understand the effects of dumpsite location on the quality of water in surrounding areas. Analysis of the physical characteristics of the groundwater samples reveals that turbidity, odor, and appearance were all found to be within the WHO standard limit in every sample location. The descriptive statistics for the physical parameters of groundwater include Temperature, Turbidity, Conductivity, Total solids, Total dissolved solids, Total suspended, and Distance accordingly. We observed that among these physical parameters. Conductivity recorded the highest mean value as (Mean = 307.79286; Standard Dev = 108.270188) while total suspended recorded the least mean value as (Mean = 0.32833; Standard Dev = 0.333192). We concluded that the research work on the effects of land pollution on groundwater in the study area established that biophysical, economic, and social factors cause pollution into land terrain, biodiversity loss, groundwater pollution, displacement of farmland, and threat to life. Physico-chemical data tell us how much the water is polluted using tests generated from laboratory analysis. We recommended that the inhabitants should be educated on the dangers of drinking contaminated water.
