Precision electrical resistance has been identified as a testing method that could be used to determine the composition (lead or copper) of underground water service lines, but other potential techniques may exist. This project will investigate various testing options to develop a methodology for discerning, to the extent possible, the composition of service lines from the street main to the property owner’s home or business. The research will also consider external influences that could affect these testing methods, such as soil conditions, proximity of other pipes (such as sewer and gas), and effects of internal home distribution piping.
Facilitated Research Partner: Massachusetts Water Resources Authority.
October 2017-March 2018 - The technique identified is the resistance measurement of a pipe.
January-March 2019 - After conclusive experimentation in the laboratory, testing in the field has begun. The equipment used for laboratory experiments was modified for usage in the field.
