Effects of Gas Flaring On Air and Groundwater Quality in Ebedei and Ashaka, Located in Ukwuani, Delta State, Nigeria

This research examines the effects of gas flaring on air and groundwater quality in Ebedei and Ashaka, located in Ukwuani, Delta State, Nigeria. Data on air pollutants, including sulphur dioxide (SO₂), nitrogen dioxide (NO₂), and carbon dioxide (CO₂), as well as groundwater quality parameters, were collected during both the wet and dry seasons through systematic sampling techniques. The findings indicate that levels of SO₂ and NO₂ exceeded the permissible limits set by the World Health Organization (WHO), posing significant threats to air quality and public health. Conversely, CO₂ concentrations remained within acceptable ranges. Groundwater analysis revealed slightly acidic pH levels, elevated biochemical oxygen demand (BOD), and high concentrations of iron, lead, and phosphates, all surpassing WHO standards and pointing to contamination caused by industrial emissions and acid rain. Statistical analyses demonstrated strong links between SO₂ and NO₂ emissions and groundwater quality, highlighting their harmful effects. Seasonal differences in pollutant levels were minor, suggesting that human activities are the primary source of pollution. The study emphasizes the urgent need for stricter environmental policies, effective pollution control measures, and ongoing monitoring to protect local communities and ecosystems.
