Really quick update on the water contamination issue affecting Paradise Valley and parts of Scottsdale -
According to a news report on Channel 12's ten o'clock news, test results show that the TCE contamination levels are down to acceptable levels, however, customers shouldn't drink or prepare food with tap water until they have been told by EPA, state, and Arizona America Water officials that the tap water is safe for consumption.
The system still needs to be flushed.
