Physicochemical water quality and basic soil parameters of Embung B, Institut Teknologi Sumatera: a preliminary assessment
Abstract
Monitoring physicochemical parameters is essential for establishing baseline information on the ecological condition and water safety of small reservoirs. This study provides a preliminary assessment of the water quality of Embung B based on selected physicochemical parameters and iron (Fe) concentration. Water samples were collected from three spatially representative locations and analyzed for pH, electrical conductivity, total dissolved solids (TDS), and Fe(III). TDS was determined using both gravimetric and in situ meter-based methods, while Fe(III) concentration was measured colorimetrically through the formation of the Fe(SCN)²⁺ complex at 480 nm. Meter-based TDS measurements indicated relatively low dissolved solids, whereas gravimetric results showed notable variability, highlighting method-dependent differences. Water pH values ranged from 8.31 to 8.83 and remained within the permissible range (6–9). Electrical conductivity values suggested low ionic strength, and Fe(III) concentrations (0.178–0.241 mg/L) were below the national drinking water limit of 0.3 mg/L. Overall, the results indicate that the water quality of Embung B, based on the measured physicochemical parameters, complies with applicable regulatory standards at the time of sampling. These findings provide baseline information to support environmental monitoring and educational activities, while emphasizing the need for extended spatial, temporal, and methodological assessment in future studies.
