- Project No 1010
- Project Name Identification and prevention of chemical contamination causing taint and odour in water from coal tar enamel lined pipes
- Lead Organisation Melbourne Water
- Research Lead RMIT University
- Main Researcher Felicity Roddick
- Completion Year 2013
This project developed analytical methods sensitive enough to detect the very low levels of compounds that leach out of old coal tar enamel-lined pipes, then catalogued the chemicals and the levels they were found at in a problematic pipeline. One of the chemicals leaching out of the old lining is probably acted on by microbes to produce another substance with an earthy, musty flavour. None of these were toxic in tests and they are therefore unlikely to pose a risk to human health.
