The testing was conducted by a specialized firm experienced in water testing and the samples were analyzed by a certified laboratory.
The testing protocol used was recommended by the New Brunswick Department of Health and involved taking a sample from the cold water tap as soon as the tap was opened (first draw). These samples were sent to the lab for analysis.
For all the locations where lead levels were found to be above the guideline on first draw, a second sample was taken after the water was run for 30 seconds (second draw).
Drinking water should have no more than 10 micrograms per litre (ug/L) of lead, as measured on the second draw after a 30 second flush.
Of the 132 locations tested:
- 129 locations tested below lead levels of 10 ug/L on the first draw
- 3 locations were retested with a second draw
- 0 locations had a result above the 10 ug/L guideline on second draw
Water testing took place in Thornton House on Aug. 15, 2016 and Aug. 24, 2016 before the building was re-opened to students after a year-long renovation project.
A total of 136 locations in the building were tested using the first draw/second draw method described above.
In the initial results, three locations tested unusually high for lead on first draw. It was suspected that the cause was aerators that had not been cleaned post-construction.
The aerators were subsequently cleaned and the three locations were retested. All three tested well within the guidelines during the re-test.
All cleaning and testing was complete before residents returned to the building.
