Abstract :A comparative study on the water quality of the interstitial water of 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 insert ignore into journalissuearticles values(The EZODO Multi-meter);. Dissolved oxygen insert ignore into journalissuearticles values(DO); was measured with a Milwaukee Dissolved oxygen meter while Biochemical Oxygen Demand insert ignore into journalissuearticles values(BOD); was determined by the 5-day BOD test insert ignore into journalissuearticles values(APHA, 2005);. The temperature ranged between 28.3 to 29.3℃ in the Opro-ama creek and 26.0 -26.8℃ in Buguma creek. The pH value ranged from 6.2 to 6.8 in Opro-ama creek while that of Sa-ama creek was between 6.8 and 6.99. Salinity ranges from 9.1 to 9.5 insert ignore into journalissuearticles values(ppt); in the Opro-ama creek while Sa-ama creek recorded a range between 11.2 to 12.0 insert ignore into journalissuearticles values(ppt);. The dissolved oxygen was between 1.5 and 2.3 insert ignore into journalissuearticles values(µS/cm); in Okpoka creek meanwhile Sa-ama creek varied between 4.6 and 4.10 insert ignore into journalissuearticles values(µS/cm);. The biochemical oxygen demand values were between 1.4 to 2.3 insert ignore into journalissuearticles values(µS/cm); in Opro-ama creek while that of Sa-ama was between 1.9 to 2.4 insert ignore into journalissuearticles values(µS/cm);. The conductivity values for the Opro-ama creek were between 10.3 and 10.6 while Sa-ama creek recorded a value of 12.5 to12.6 insert ignore into journalissuearticles values(µS/cm);. there were significant variations insert ignore into journalissuearticles values(P<0.05);. It was observed that Sa-ama creek had more impacted water parameters than the Opro-ama creek. The results were that most parameters were not within the permissible limits of WHO, USEPA, and DPR. There is therefore a need for regular environmental impact assessment by authorized regulatory bodies in this region.
