Abstract
Detailed geochemical investigation of water from River Kassa was carried out to assess trace element distribution in the river system. The results showed significant enrichment of these elements Pb, As, Co, Cr, V, Ni and Fe. The value of index of geoaccumulation (Igeo) is approximately 2; for Zn and Pb which indicates, moderate contamination. Areas of the river system with anomalous value of trace element concentrations are those where mine tailings have been deposited close to the river channel or places where run off from adjoining farmlands and settlements enter the river. The major sources of contamination are mining and agricultural activities on the flood plain of this river. The anomalous concentration of As, V, Cr, Co and Pb need further investigation in view of their health implications on man and aquatic lives.
Highlights
River Kassa is a major river which flows through several mining settlements and inhabitants of these areas depend on it for their domestic, agricultural and mining activities
The concentration of Co and Fe increases from hornblende pyroxene fayalite (Hpf) to Rbg/biotite granite (Bg) while other trace elements shows no defined trend in concentration from one rock type to the other
The concentration of Co and Fe increases from Hpf to Rbg/Bg while other trace elements shows no defined trend in concentration from one rock type to the other Trace element concentrations in the upper Kassa River are generally higher than the lower portion
Summary
River Kassa is a major river which flows through several mining settlements and inhabitants of these areas depend on it for their domestic, agricultural and mining activities. The river drains an area of more than 1000km during periods of high flow with a water shed of about 100km. Tributaries of Kassa River are channeled into their concessional area for processing of tin ore. The Kassa river system which is the southeastern part of Jos-Plateau begins at the point of major hub of tin mineralized communities. Land use on the path of flow is mainly agricultural and washing of tin ores
