Evaluating Groundwater Contamination in the Vicinity of a Cemetery for Environmental Concerns

Abstract

Groundwater pollution near cemeteries poses risks to the environment and public health. This study investigated groundwater quality around the Third Cemetery in Benin City, Nigeria, using analytical techniques like a PQWT water detector. Groundwater samples from boreholes near the cemetery were analyzed for physico-chemical and bacteriological parameters. Water Quality Index (WQI) modeling assessed drinking water suitability. Geophysical surveys with a PQWT-TC 300 detector identified subsurface anomalies indicative of potential contaminants. Results revealed elevated levels of contaminants like bicarbonate, magnesium, manganese, ammonium, iron, lead, and chromium exceeding recommended limits. Spatial correlations showed higher contamination levels in boreholes closer to the cemetery, suggesting cemetery-related activities as contributing factors. Lead, chromium, and ammonium were consistently present across distances. The WQI categorized the water as "Very Poor" and "Unsuitable for Drinking," indicating health risks. The study highlights the need for action to preserve the environment, promote public health, and improve access to clean water in areas near cemeteries.
