But Tinian again exceeded the maximum contaminant level last month, the monthly report from the CUC laboratory showed.
Laboratory manager Heidi Yelin said none of the 82 samples collected throughout the Saipan public water system contained total coliform in October.
“This system achieved the goal of 100 percent compliance of the total coliform rule,” Yelin and CUC deputy director for water and wastewater Bruce R. Megarr told Division of Environmental Quality Director Frank Rabauliman.
In September, CUC laboratory reported that two total coliform positive samples were found in Tinian’s public water system.
The system, CUC said, was required to issue a public notice of the violation of the maximum contaminant level before Oct. 28.
Since the Tinian public water system wanted to determine that its system had resolved the source of the September total coliform contamination, it collected four samples from the affected area on Oct. 20, Yelin said.
One of those samples contained total coliform, she added.
Yelin said they collected three repeat samples and six routine samples for October, and none showed the presence of total coliform.
The cause of the positive samples collected in September had been resolved, CUC said.
On Rota, she said they collected three routine safe drinking water samples last Oct. 5 and none contained total coliform.
