Two-Way ANOVA for Comparison of Remedial Nutrient Solution and Enhanced Natural Attenuation Using SPSS for Treating Petroleum Contaminated Soils

Statistical comparison of two remediation methods: Remedial nutrient solution and enhanced natural attenuation were analyzed in terms TPH different soil samples collected from Khana Local Government Area Rivers State, Nigeria at locations placed inside sample bottles labelled A to D replicated into two, one for each the above treatment technique. The was determined using GC analyzer after solvent extraction carried out hexane/dichloromethane mixture. Three batches performed on every interval eight weeks a duration six months. result obtained two-way ANOVA factorial experimental design test significance various sources variation. From obtained, source variation interactions non-significantly other which means that irrespective number or combination both treatment, they will still not be significantly other. batch replications this applied (methods used), always individual showed efficiency Nutrient Solution method better than Enhanced Natural Attenuation method.
