The city recently sent a notice to its water customers about slightly elevated TTHM levels. You can find a list of FAQs below. Updates on the temporary and permanent solutions will also be available on this page.
Does this affect all Goodyear residents?
No. This notice applies to city of Goodyear water service area customers south of the I-10 only.
Some Goodyear residents receive water service from other providers. If you are unsure who provides your water service, please check your utility bill or contact Water Services for help confirming your provider.
Why did I receive this water quality notice?
You received this notice, because recent required water quality testing showed that Total Trihalomethanes, or TTHMs, in the city of Goodyear water system slightly exceeded the federal drinking water standard.
This notice applies to city of Goodyear water service area customers only. If you are unsure who provides your water service, please check your utility bill or contact Water Services for assistance.
The city is required to notify customers when this type of water quality standard is exceeded, even when the situation is not an emergency.
Is my drinking water safe to use?
Yes. This is not an emergency, and your water remains safe to drink and use as normal. If the water is ever unsafe to drink for any reason, the city would notify customers within 24 hours. No immediate corrective action is required by customers.
Do I need to boil my water, buy bottled water or install a filtration system?
No. This is not a boil-water notice, and customers do not need to boil water, buy bottled water or install a filtration system because of this notice.
Some residents may choose to use bottled water or filtration systems based on personal preference, but the city is not requiring any corrective action by customers. While you do not have to install filtration systems, if you do have a filter on your refrigerator or reverse osmosis for your drinking water, they will remove TTHMs.
Is the water safe for showering, bathing and other household use?
Yes. The water remains safe to use as normal, including for showering, bathing, handwashing, laundry and other household uses. This notice is not a boil-water notice, and no special precautions are required for normal household use.
Is the water safe for pets?
Yes. No corrective action is required for customers, and the water remains safe to use as normal.
Why am I learning about this now?
TTHM compliance is based on a running annual average of required quarterly testing results, not a single daily test result. The city tests its water quarterly. When the most recent annual average showed a slight exceedance of the federal drinking water standard at one testing location, the city was required to notify affected customers within 30 days.
This is the first time the city has had to issue this type of notice.
What is the city doing to address the issue?
What is the city doing to address the issue? The city has taken several steps to reduce TTHM levels and expects the equipment associated with the issue to be repaired by June 9. To resolve the issue on an ongoing basis, additional actions include lowering chlorine residuals, verifying that systems are working properly, conducting additional system flushing, completing additional testing and continuing to monitor water quality.
Is additional testing being done to make sure the water remains safe?
Yes. The city is proactively conducting additional testing and continues to monitor water quality.
Customers do not need to conduct their own testing because of this notice. Residents can view the latest annual water quality report by scrolling down on this page.
What are Total Trihalomethanes, or TTHMs?
TTHMs are compounds that can form when chlorine, which is used to disinfect drinking water, reacts with naturally occurring organic materials in the water. Chlorine is used because disinfecting drinking water is an important public health step. It helps eliminate harmful bacteria and viruses that can cause illness.
What are the possible health effects of TTHM exposure?
This situation is not an emergency and does not require customers to take corrective action.
Health risks related to TTHMs are generally associated with long-term exposure over many years, not short-term consumption. Individuals with specific health concerns, including those with compromised immune systems, should contact their healthcare provider.
Is this notice related to water rates or data centers?
No. This notice is related to required drinking water quality testing for Total Trihalomethanes, or TTHMs. The notice was triggered by the annual average of quarterly water quality testing results. It is not related to water rates or data centers.
How can I ask questions or stay informed?
Residents with questions may contact Water Services by phone at 623-932-3010, Option 3, or by email: Mark Ortiz, Environmental Programs Manager, Mark.Ortiz@goodyearaz.gov.
