Quantify and interpret concentrations of explosives residues in soils and surface waters of five sampling points SP1-SP5 of Boko Haram/Military detonation sites in Gwoza LGA and assess spatial differences using a one-way ANOVA in triplicate measurements mean±SD. Methods: For soils and sample waters, nitroaromatics TNT, DNB, TNB, 2,4-DNT, 2,6-DNT, NP, NT and nitramines RDX, HMX were shown as mean±SD (mg/kg) and (mg/L). We calculated ANOVA from summary statistics to compare differences among sampling points in each compound and matrix of which we reported effect sizes. Soils’ concentrations were one to three orders of magnitude higher than water’s, as a byproduct of strong sorption. Hotspots were found in SP4 for 2,6-DNT and 2,4-DNT and in SP2–SP3 for TNT . Several soil analytes revealed significant spatial heterogeneity according to ANOVA, and “notably TNT, 2,4-DNT, 2,6-DNT” had a large effect (η² = 0.8). The result is that Patterns “reflect the proximity to detonation/handling areas, soil organic matter mediated sorption, and the transformation of 2,4,6-TNT to DNT isomers, whereas aqueous concentrations remain low due to the dilution and photolysis”. As a consequence, the findings qualify for a targeted risk assessment and erosion/storm-water controls at hotspot
