This paper reviews three models for analyzing slug test data to determine hydraulic conductivity of hydrocarbon contaminated wells in the study area. 50 grams/litre potassium permanganate (KMnO₄) was used as permeating fluid for the remediation of the site. Data of the slug-in test from five (5) observation wells varying in diameter from 0.82-1.93m in the study area in Baruwa, Lagos Nigeria were analyzed with three models used in the study, namely; Hvorslev, Ferris –Knowles and Earth Manual models. Analysis of the data showed that all three analytical methods produced similar range of magnitude of the order of 10^-4cm/sec values of hydraulic conductivity.
