Abstract:
The physico-chemical parameters were sampled from February to September, 2019. Surface water samples were collected from three sampling sites for physico-chemical analysis in 1-litre plastic bottle. Water samples for water quality were collected not below 0.5 m. Water temperature (mg/L), pH, electrical conductivity (µS/cm) and total dissolved solids (mg/L) were determined in-situ using Hannah instrument while secchi disc was used for transparency (m). Results were presented using inferential and descriptive statistics, while diversity dat was analyzed using diversity software. Range of values of physico-chemical parameters measured were water temperature (27.2 to 32.6°C), air temperature ( 26.0 to34.8°C), transparency ( 0.61 to 1.04 m), pH (5.4 to 7.9), total dissolved solids (799 to 2000 mg/L), conductivity ( 1714 to 3999 μmhos/cm), salinity (15.0°c to 34.8%), Nitrate (2.49 to 3.23 mg/L) dissolved oxygen (5.40 to 8.3mg/L) and alkalinity (3.0 to 73.3 mg/l). High variation in salinity shows that Lagoon is brackish water environment.
