Metal Ions Analysis of Water in the Industrial Area in Gaya District of Bihar State - India

Abstract

The groundwater quality assessment conducted in the Manpur Block near Falgu River was aimed at evaluate the suitability of the water for drinking purposes. The study measured various water quality parameters, including hardness, turbidity, conductivity, pH, TDS (total dissolved solids), alkalinity, chloride, content and dissolved metals. These parameters were compared with the acceptable limits prescribed by the BIS (Bureau of Indian Standards) to determine if the water meets the required standards for safe consumption. The study included analysis of the acceptability of groundwater sample, metal contamination, potential risks, and analysis of surrounding groundwater.  Some of the groundwater samples collected were found to be acceptable within the BIS limits for drinking water quality, while others exceeded these limits. The average concentrations of metals in the groundwater samples followed the trend: Mn (Manganese) > Zn (Zinc) > Fe (Iron) > Ni (Nickel) > Cu (Copper) > Cr (Chromium). This indicates that manganese and zinc are the most prevalent metals, while chromium and copper were found in the least amounts. Presence of certain metals such as nickel and iron beyond the acceptable limits can invite a serious health hazard to the local population, especially if the water is consumed regularly without proper treatment. The study assessed not only the water quality of the Falgu river but also the quality of nearby groundwater, which may be affected by industrial activities in the congested area. This relationship is important to understand the broader environmental impact on water resources.
