Approximately 20 people who dined at two Pine restaurants in the past week are experiencing vomiting, diarrhea and headaches and one of the area's water supplies is suspected of having something to do with it.
"There's a small, private water company up there ... which may be affected," said Payson Health Inspector Svanna Jones. "It's a surface water source, so it may just be that the chlorinator is down or something."
Lois Krebs, a member of the Pine Water Association, confirmed that the health department was testing that system's water supply.
The Pine Water Association serves about 120 customers.
"I took water samples down to the lab last night, and they won't have the results until about 3 p.m. today (Friday)," Jones said. "Until then, we're having someone contact everyone who is sick and tell them to go to the doctor and ask for an entero bacter viral test. That's really the only way you can verify exactly what it is."
Until the water analysis is complete, Jones said, those on the water system should boil their water before drinking it.
