This paper reports the finding of the impact of sand mining within Ado Ekiti metropolis. Three
locations were chosen from where field physical measurements and observations were made.
Laboratory analysis such as compressive strength test and particle distribution analysis were
conducted on samples collected at the locations. Global Position System (GPS) was used to
determine the coordinates and elevations of the mine sites to produce the digitized topography maps
of the sand mine sites using Arc GIS software. The volume of sand mine was determined thereafter.
The result obtained from topography shows that the volume of sand mined in Afao, Ijan, and Federal
Polytechnic Ado-Ekitiwere 3.62 metric Tonnes 1.34 metric Tonnes and 0.51 metric Tonnes
respectively. The sample size classification showed that clay and silt content of all the location were
5% with sand range between 75 – 82%, and the gravel range between 13 – 20 %. Also the
absorption test shows that Afao and Ijan have 11.76 % and 10.96% respectively while Federal
Polytechnic Area of Ado Ekiti had 13.23% and 13.92% respectively. The conclusion drawn from the
observation and analysis of the field data was that indiscriminate sand mining pose environmental
threats to the life and properties of the people around the sites.
