In the Netherlands, a large drinking water distribution system exists which composes of a complex network of underground pipes owned by several water companies. Part of the drinking water distributions pipes consist of cast iron pipes of which some have been installed more than 80 years ago.¹ To prevent leaks, it is desirable to have insight into the condition of these pipes and the risk of leakages or even pipe bursts. During local replacements and maintenance work, corrosion is regularly found in the pipes and previous research⁷ has indicated that Microbiologically Influenced Corrosion (MIC) may be involved in this corrosion that is found in the pipes.

MIC-causing microorganisms were investigated in a 16” diameter and 9.6 km long injection water pipeline. Nitrate was added to the water and pigging debris from the pipeline showed that both sulfate-reducing bacteria (SRB), nitrate-utilizing bacteria, and methanogens were present in numbers of 105 – 106 cells/g.

Microbial contamination is a major concern in oil/gas system or industrial water operation where it can result in multiple major corrosion issues and efficiency losses. Chemical treatment is the primary means to control microbial contamination, but due to changes in temperature and water sources, this results in major shifts in the microbial levels and populations which can influence the efficacy of these treatments.

Due to the shifts in the number of bacteria and the change in the dominant microbial species, optimal dosage of biocide is very difficult. Inadequate dosage regimen will result in major losses, whilst excess chemical dosage will incur unnecessary costs whilst also increasing the environmental load. A quick, reliable microbial measurement will help identify critical control points in the process and will allow optimization of dosing of the treatment program.

Agar growth, ATP, and media bottle testing have long been the standard for microbial detection, but these can lack the specificity, sensitivity and response time needed to adequately address the changing conditions in the industrial system described. The molecular-based approach, quantitative polymerase chain reaction (qPCR), described in this article, provides a near real-time method to measure bioburden, allowing operational decisions to mitigate issues to occur more rapidly.

Microbiologically influenced corrosion (MIC) is a key risk to oil and gas infrastructure and confers great cost to asset owners. The AMPP 2021 IMPACT Canada study, which analyzed the energy, manufacturing, and mining sectors, shows the cost of corrosion in Canada is roughly $51.9 billion per year. To break this down further, MIC is estimated to make up roughly 20% of all corrosion which is roughly $10.4 billion in Canada alone, each year.
