Abstract
The Ikot Effanga area of Calabar, Southeastern Nigeria, is located close to a municipal waste dump. The area is defined by latitudes 050001N and 050251N and longitudes 0080201 E and 0080251 E. The aim of the study was to assess the impact of the waste dump on the groundwater resources of the area. Groundwater samples were obtained from 10 boreholes located around the dump site. The samples were collected during the peak dry season and peak rainy season for comparison. Physicochemical parameters were analyzed. Static water level and surface elevation of the boreholes were used to determine the groundwater flow direction. Results obtained were compared with the NSDWQ and WHO standards. From the result, it was observed that groundwater in the area is acidic as the mean pH values were 4.03 and 3.57 for dry and wet season respectively. Other physicochemical parameters analyzed showed that there were no significant variations between the dry and wet season. Also, groundwater from the area was classified as fresh and suitable for domestic and agricultural purposes. The general flow direction of groundwater in the study area is NW-SE. While the present study showed that the dumpsite does not have significant impact on the groundwater resources either due to geology or natural attenuation
Highlights
Rapid urbanization, increased population, advancement in technology and the general improvement in the standard of living in many countries of the world have led to generation of large amount of municipal wastes
In an effort to study the level of groundwater contamination of the area, ten (10) water samples were collected from boreholes around the vicinity of the dumpsite (Table 1 and 2)
Dissolved Oxygen (DO) in the study area varied from 13-24mg/l with mean value of 16.6mg/l during the dry season and mean value of 220.5mg/l during wet season
Summary
Rapid urbanization, increased population, advancement in technology and the general improvement in the standard of living in many countries of the world have led to generation of large amount of municipal wastes. Disposal of these wastes is a global concern, most especially in the developing countries across the world, where less attention is paid on waste management due to poor funding leading to improper design and poor waste management technique (Doan, 1998). Nature of waste, age of landfill and climate may be some important factors that affect the level of impact on groundwater, local geology, particle size, degree of compaction and site hydrology significantly affect groundwater quality around dumpsites. The disposal of wastes at Ikot Effanga dumpsite calls for concern due to the growing population which has led to the increased in the demand for potable
