Some residents of Hereford are unsettled after a letter they got with their water bill.

The letter informed residents TCEQ found Hereford's water exceeded the limit for gross alpha emitters, a measurement of radiation.  The limit if 15, Hereford's water scored 16.

Although the city maintains in the short term there is no danger to residents.  However prolonged exposure could lead to an increased risk for cancer.

Hereford is retesting it's water to confirm the results.  They also plan to test at the city's water wells to hopefully identify where the alpha emitters are originating.
