HEAVY METAL CONCENTRATION AND pH LEVELS IN SOILS OF THE MAIN DUMPSITE OF NAROK CENTRAL SUB-COUNTY.

Solid waste has been a major challenge in Narok town and its environs over the years causing pollution of water bodies such as rivers, blockage of drainage systems consequently leading to flooding that translates to loss of life and property. In this study soil samples were collected from the main dumpsite for heavy metal and pH analysis. They were analyzed for Lead (Pb), Cadmium (Cd), Chromium (Cr) and Zinc (Zn). This was done using Atomic Absorption Spectrophotometer (AAS-PG 990) and pH meter (HANNAH pH 211). These results indicate that these metals were beyond the levels at the reference sites for unpolluted soil 20m away from the dumpsite. The PH range was between 7.19±0.6 - 9.8±0.12 with a mean of 8.29±0.84 in the dump site during the dry season and 8.14±0.25 during the wet season. The mean pH during wet and dry season was not significantly different (P>0.05).The dumpsite was found to be about 50m from the Narok River while the recommended distance should be 500m. The results indicate negative effects of the dumpsite to the environment and therefore measures should be taken to ensure proper waste disposal and management. With the major dumpsite being near the river, this study recommends its relocation to prevent further water pollution, which may be a cause of human and livestock diseases.
