Teresa Gray Salt Lake City Water System 1530 S West Temple Salt Lake City, UT 84115
Subject: Notice of Source Deactivation for Salt Lake City Water System; UTAH18026 Teresa Gray:
On November 13, 2024, Dustin White notified the Division of Drinking Water (the Division) that the following sources were inactive for the entirety of 2024.
• ARTESIAN BASIN WELL #2 (Identified as WS042)
• 15TH EAST WELL (WS018)
• 4TH AVE WELL (WS017)
To avoid issuing yearly monitoring violations, the sources listed above were changed from an “Active” status in the Division’s database to an “Inactive” status.

With this change, ARTESIAN BASIN WELL #2 (WS042), 15TH EAST WELL (WS018) and 4TH AVE WELL (WS017) are not currently allowed to be utilized as a source of drinking water until they have been formally reactivated.
In most cases the source reactivation process involves only collecting the outstanding samples that
were missed during the period of inactivity. The reactivation process does not require that systems obtain new operating permits. Inactive facilities which are plumbed into the water system can pose a risk to public health if not maintained properly. Per Division policy, all inactive facilities are inspected during water systems triannual sanitary survey.

As of December 10, 2024 the following samples are required to be collected and reviewed by the Division prior to placing the source back online. It is strongly recommended that the system run the source to waste for an adequate amount of time prior to sampling to ensure that the samples are representative of the aquifer.
