By Tessa Roy, WPRO News A boil water advisory issued for parts of Narragansett and South Kingstown last week remains in effect as of Thursday.
Five different water systems and about 38,000 customers are affected.
State Health Department spokesperson Joseph Wendelken said it’s possible the advisory could be lifted by the weekend, but made no promises.
He said affected customers should continue boiling all water used for consumption until the Health Department gives the all clear.
Wendelken said at least three days of clean water samples are necessary before a boil water advisory can be lifted.
“They only started sampling on Wednesday and the reason why that was done was because they were doing an investigation into the source and they were also doing treatment of the water.
Doing that treatment takes time,” he said.
The Health Department’s recommendations from last week remain the same.
Affected customers should vigorously boil for one minute all water that may be consumed, and should avoid swallowing the water while bathing.
