Study of Groundwater and Surface Water Remediation
Abstract: Groundwater remediation is the process of treating contaminated groundwater by removing contaminants or converting them to harmless chemicals. Water that saturates the pore space in the subsurface and is located beneath the ground surface is known as groundwater. Between 25% and 40% of the world's drinking water comes from boreholes and dug wells. Farmers need groundwater to irrigate crops, while industry use it to make everyday items. Even though most …

Evaluating Remedy of Oil Polluted Environment Using Fermented Cassava Liquid
Abstract: A 28-day experimental investigation was conducted to evaluate the effectiveness of fermented cassava liquid in the bioremediation of crude oil-contaminated soils. Three soil types, namely clay, sandy-loamy, and swampy soils, were examined. Cassava liquid was fermented for six days to allow sufficient microbial growth before being introduced into the contaminated soil samples. Uninoculated contaminated soil served as the control. Soil samples were collected at one-week intervals throughout the study for …
