The phone has been ringing off the hook at Bend City Hall Tuesday after reports that a toxic chemical may be in the Avion Water system. City officials are very frustrated and question the accuracy of testing attributed to the environmental working group. A newly released study states that Bend is tenth among 35 cities in the nation for the presence of hexavalent chromium n it's drinking water. “I’m concerned about the verbiage coming out and saying that the City of Bend is supplying toxic carcinogenic water which is not true, and I am concerned that they are not supplying us with provable data, they are not giving that to us.” City of Bend Laboratory Manager Steve Prozak says this chemical was made famous in the legal case involved Erin Brockovich. Prozak says the Unites States Environmental Protection Agency has yet to determine what is a safe level for hexavalent chromium. This study says the sample from Avion Water was .78 parts per billion. Prozak says the City does test for total chromium levels and those are well within safe limits.
