Abstract: In this study, the soil of 16 landfills from 15 Northwest Florida counties was characterised through sieve analysis. On the basis of plate counts, it was found that there were around 3.0 × 10⁴ to 9.5 × 10⁵ Colony-Forming Units (CFU) per gram of soil for the soil of Northwest Florida. Through Polymerase Chain Reaction (PCR) analysis, Bacillus subtilis, Bacillus cereus, Bacillus thuringiensis and Pseudomonas aeruginosa were identified as dominating species

Keywords: landfill leachate; soil characterisation; microbial characterisation; iron release; microbes; groundwater pollution; water pollution; USA; United States; sieve analysis; polymerase chain reaction; PCR; iron reducing bacteria.
