Valley Pioneers water samples pass inspection

The Valley Pioneers Water Co.

received a clean bill of health after eight water samples taken on Monday showed no presence of potentially harmful bacteria, according to General Manager John Clayton.

None of the samples tested positive to the presence of coliform, Clayton said on Wednesday.

He immediately ordered chlorination of the water system after monthly testing done on July 11 determined the presence of the coliform in five of eight samples.

Valley Pioneers violated water quality standards established by the U.S.

Environmental Protection Agency because coliform appeared in more than 5 percent of the samples taken during the July testing period.

Coliform can cause health problems such as diarrhea, cramps and nausea, according to a public notice Clayton issued last week.

"It was a nonacute violation, and it was taken care of immediately – I would guess within a few hours," Clayton said.

Although Valley Pioneers was not required to do any testing until August, Clayton said he had other samples taken on Monday.

The next samples will be taken Aug.

7.

Clayton said he has not determined the cause of the contamination last week.

He added Valley Pioneers staff probably will continue chlorination for another week as a precaution.

He expressed concern about chlorination adding a distaste to the water, while saying only a minute amount of chlorine is added to the system.

"If you took a gallon of water and separated it into one million separate parts, then half of one part would be chlorine," he said.

Valley Pioneers supplies water to 1,938 meters in a 24-square-mile service area in Golden Valley.
