**3.8 Salinity**

The salinity of the samples collected from the sites in the study area range from 42 mg/l – 508 mg/l. The high values recorded were from sample sites SD2 (483 mg/l), MD2 (496 mg/l) and MD3 (508 mg/l). The salinity values for all sample sites are higher than the value range of 1.36 0.13 mg/l to 5.27 0.21 mg/l, with a mean value of 2.55 0.109 mg/l reported by Bolarinwa, Fasakin and Fagbenro [23] in the analysis of the physicochemical parameters of coastal waters of Ondo State, Nigeria. The results obtained in this study are within WHO's permissible range of ≤600 mg/L.

**Salinity:** The salinity of water samplwes collected from the sites in the study area ranged from (28.1 476nmg/l) as shown in **Table 4** with a mean value of 36.33 4.51–297.33 234.35 during the rainy season and the value range of (33.4 – 508 mg/l) as shown in table with a mean value of 50.9 14.79–350.7 262.19 as shown in **Table 5** the salinity levels obtained in this study revealed that both in the dry and rainy season the results were within the WHO permissible limit of ≤600 mg/l.
