Subject area	Engineering
More specific subject area	Chemical Engineering, Environmental Engineering, Sustainable Environmental Sciences and Management
Type of data	Tables, graphs, figures
How data was acquired	Absorbance data measurements from crude oil polluted soil sample systems using a Jenway 6405 ultra violet visible (UV/VIS) spectrophotometer instrument
Data format	Raw, statistically analyzed
Experimental factors	Absorbance data monitoring were executed as laboratory experimental data sourcing on crude oil polluted soil samples that had been inoculated using Pseudomonas aeruginosa strain of bacteria
Experimental features	Air dried loamy soil was polluted by two different concentrations of two types (raw and treated) of Nigerian Escravos Light blend of petroleum and then inoculated using Pseudomonas aeruginosa strain of microbe, for bioremediation monitoring via periodic absorbance measurements
Data source location	Loamy soil was collected from Covenant University Farm, Nigerian Escravos Light crude oil blend was sourced from Chevron® Nigeria, Delta State, Nigeria, Absorbance measurement procedures was carried out at Covenant University, Ota, Nigeria (Latitude 6.6718°N, Longitude 3.1581°E).
Data accessibility	The comprehensive dataset of the bioremediation effects of Pseudomonas aeruginosa, via absorbance monitoring, on soil that has been polluted by raw and treated crude oil is made available in this data article
