Several analytical and microbiological tools were explored for use in detecting and diagnosing microbiologically influenced corrosion (MIC) in failed fire protection systems obtained from seven different sites. The tools used in this study included microbial community analysis, immunoassay analysis, ion chromatography, sulfide testing, and scanning electron microscopy. Since detecting and diagnosing MIC in failed systems is not a simple and definitive process, employment of a combination of different analyses increased the accuracy for a proper diagnosis.
