Waltham officials warned residents last night that the city's drinking water showed a higher than normal level of total coliform bacteria this week, but assured locals that the findings do not present a public health threat.
A trace amount of the bacteria was detected by water testers in several samples this week at 1560 Trapelo Rd., officials announced.
Town engineers have been flushing hydrants and adding chlorine to the city's water to fix the problem.
According to the US Centers for Disease Control, coliform bacteria typically do not make humans sick, but because the microbes that do cause disease are hard to test for in water, the total coliform level is tested instead. If that count is high, that indicates there could be harmful viruses, bacteria, and/or parasites in the water.
Waltham officials said they would provide an update when the water is resampled.
The mayor and engineering officials could not immediately be reached.
