Plumbing Contractors ? Building Contractors ? Insurance Companies ? Developers ? Real Estate Agents ? Municipal and Private Water System Managers ? Property Owners This booklet is a resource on microbiologically influenced corrosion for its understanding, prevention and remediation of the problems that are "bugging" your pipes.
