Conduct analysis to define biofouling and biocorrosion mechanisms involved in the rapid corrosion of multiple monitoring well casing, potentially compromising critical data on potential chemical and radiological contamination of ground water. Ground Water Science supplied project scope, an on-site laboratory capability (with no outside inputs or transport out) to analyze for microbial contributors to biocorrosion, documentation of evidence of biocorrosion from pulled well components, and definition of a method to measure corrosion potentials between inner and outer casings through grout. Project conducted on a very rapid time scale.
