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 …

Experimental Analysis of Physical Parameters in Treated Water
Abstract: During the first phase, the surface water treatment plant at Saidabad treats 225 million liters of water per day. In the treated water, turbidity, color, total coliform, fecal coliform, and hardness are reduced; on the other hand, conductivity and total dissolved solids increase. In the wet season, turbidity is high due to relatively coarse particle dispersions in river water. All other parameters, such as, color, total and fecal coliform, hardness, …
