Article Regarding the Required Notification to Water Users of the Cave Creek Water System

The Town of Cave Creek has submitted information to the regulatory agency responsible for the current classification of our existing water treatment facilities.  A re-classification of the treatment plant has resulted in the “Public Notice” you have received.  

The Town has requested that the re-classification be reversed.  When this action is completed, no further public notifications will be required. 

Again, the notice you received indicates that the water delivered to your residence is safe to drink and use daily. YOU DO NOT NEED TO TAKE ANY FURTHER ACTION. 

We will continue to update you with news on the pending re-classification of our plant as we receive update information.

Below is the Text of the letter sent regarding the required Notification:

February 14, 2019

Dear Customer:                                               

On Feb. 1, 2019, the Town of Cave Creek (Town) received notification by the Arizona Department of Environmental Quality (ADEQ) that it is required to remove additional byproducts from its water supply. 

First off, this is not an emergency and your water remains safe to drink and use in your daily life.  Cave Creek has an outstanding record of providing safe and reliable drinking water.

This information is to advise you of the Town’s efforts to meet the highest regulatory standards. 

AZ0407016 Treatment Requirements

We are required to remove specific disinfection byproduct (DBP) Precursors between source water and filtered water.  The DBP Precursors test results from the last twelve (12) months that ended on December 31st, 2018 show that our system did not meet the required DBP Precursors removal efficiency rate.  Running Annual Average (RAA) of the DBP Precursors removal ratio for this twelve (12) month period is calculated at .9, which is below the required ratio of 1.00.

Although this is not a health emergency, as our customers, you have a right to know what happened, what you should do, and what we did (are doing) to correct this situation.

a. The notification is not a safety notification.  It is a notification that the treatment process is not as efficient as required.

b. Required chlorine levels necessary for safe water have been and continue to show both compliance and safety.  This is the primary indicator of safe water.

1.  How is Cave Creek continuing to provide safe and reliable customer service to its water customers?

Cave Creek has taken many steps to improve both monitoring and treatment of the Town water supply to better serve our customers. 

2.  What should I do?

You do not need to take other actions. We do not know of any contamination, and none of our testing has shown disease-causing organisms in the drinking water. The Town of Cave Creek has met with ADEQ and discussed a permanent solution that would modify the currently required removal percentages to a more realistic level based upon our existing treatment plant processes. 

3.  What does this mean?

This is not an emergency. If it had been, you would have been notified immediately. Total Organic Carbon (TOC, a form of DBP Precursors) has no health effects. However, total organic carbon provides a medium for the formation of disinfection byproducts. These byproducts include trihalomethanes (TTHM’s) and haloacetic acids (HAA5’s). Drinking water containing these byproducts in excess of the MCL may lead to adverse health effects, liver, or kidney problems, or nervous system effects, and may lead to an increased risk of getting cancer.

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.

If you have any question or would like more information, please contact Jim Kaylor at 480-488-6618 or [email protected]
