Impact of Artisanal Crude Oil Refining Effluents on Interstitial Water at a Mangrove Wetland, Asari-Toru Axis of Sombreiro River, Rivers State.

A comparative study on the water quality of interstitial two creeks in Rivers State was conducted. Temperature, pH, Conductivity, Dissolved oxygen, biochemical oxygen demand, Salinity, and Total dissolved solid were checked with an in-situ hand-held multi-meter (The EZODO Multi-meter). (DO) measured a Milwaukee meter while Biochemical Oxygen Demand (BOD) determined by 5-day BOD test (APHA, 2005). The temperature ranged between 28.3 to 29.3? Opro-ama creek 26.0 -26.8? Buguma creek. pH value from 6.2 6.8 that Sa-ama 6.99. Salinity ranges 9.1 9.5 (ppt) recorded range 11.2 12.0 (ppt). 1.5 2.3 (µS/cm) Okpoka meanwhile varied 4.6 4.10 (µS/cm). demand values 1.4 1.9 2.4 conductivity for 10.3 10.6 12.5 to12.6 there significant variations (P
