This work documents the vulnerability of coastal aquifers located in the Niger Delta region (Nigeria) using soil and hydrogeological data. The parameters used include depth to water levels (SWL), cation exchange capacity (CEC), organic matter content (OMC), aquifer media character (AMC), recharge (R), and soil type (ST; based on the percentages of sand, silt, and clay). The results show that the most vulnerable areas are located in the southern part of the study area due mainly to seawater. The parameters used are cheap to be obtained and the the method can be applied in other coastal areas with similar conditions.
