Abstract

Water is important in the daily activities of living things. The sources could be from the surface or ground. Rainwater is known to be pure, but its use could be reduced due to contaminants due to industrial, agricultural, traffic activities and other natural sources. Many research works have been undertaken on water pollution to provide information on the outcome for use in policymaking and monitoring. The location of this study has little or no information with regards to environmental safety. Therefore, the aim of this study was to assess the rainwater quality (July 2018 - June 2019) with reference to the physicochemical parameters. Standard methods were used in the assessment process. The results showed the mean results as follows: Total Dissolved Solids (TDS - 22.92 mg L L-1), Temperature (28.58oC), pH (6.83), Electrical Conductivity (EC - 45.3 µS/cm), and Free CO2 (22.0 mg L L-1). Statistical analyses (coefficient of variation (%)) depicted high variations in TDS, EC, and Free CO2.The only pH was skewed to the left.The results compared well with WHO standards and other references used. The present situation at the study location revealed a safe environment, but it is recommended that constant monitoring should be put in place by relevant stakeholders.
