Subject: UTAH28037, Aspen Ranch: Notice of Violation, Arsenic MCL Exceedance - Public
Notice Requirement

Jeremy Williams:

This letter serves as official notification that according to the Division of Drinking Water’s (the
Division) records, Aspen Ranch (the supplier) is in violation of both the state and federal
Maximum Contaminant Level (MCL) for arsenic, as defined in Utah Administrative Code
(UAC) R309-200-5.

The MCL for arsenic is 0.010 mg/L. Compliance with this standard is determined by calculating
the Running Annual Average (RAA) of the most recent four quarters of sample results. The
Division’s records show that the RAA for arsenic, collected from the Aspen Health Well
(identified as WS001 in the Division’s database), is 0.011mg/L. This exceeds the MCL.

As a result of this violation the Division Director has assessed 50 Improvement Priority System
(IPS) points to the supplier. Additionally, the supplier must issue public notice to all connections
served within 30 days of receiving this notice. Additional violations shall be assessed each
calendar quarter that the RAA for arsenic exceeds the MCL of 0.010 mg/L.

Required Actions by Rule for a Tier 2 MCL Exceedance Violation
With the Aspen Health Well (WS001) containing arsenic levels above the MCL, the Supplier is
required by rule to perform the following:

1. The Supplier is required to notify its water users with the enclosed Tier 02 public notice
protocol within 30 days of receiving this letter and repeat the notice every three months for
as long as the violation exists. A copy of the public notice must be submitted to the
Division at [e-mail] and [e-mail] prior to distribution. Public
notice shall be issued no later than 30 days from August 5, 2025.
2. Enact one of the following mitigation measures:
a. Identify and implement operational strategies that can minimize arsenic exposure.
b. Identify possible alternative sources for drinking water.

Please be aware any permanent treatment option must comply with the Division’s plan review
process including submittal of design, engineering plans and specification, and obtaining plan
approval (prior to construction) and then requesting and obtaining an operating permit prior to
placing any facility into service. Please contact John Chartier P.E. at [e-mail] or 435-
559-1969 if you have any questions regarding the potential plan review requirements.

Arsenic is a naturally occurring element found in the earth's crust, and its presence in drinking
water can pose a significant risk to public health. Long-term exposure to arsenic is associated
with an increased risk of various cancers, including those of the bladder, lungs, liver, and skin,
as well as non-cancerous effects like skin lesions, cardiovascular disease, and diabetes. The
toxicity of inorganic arsenic can damage cells and their DNA, potentially leading to the
development of these adverse health conditions. Therefore, regulatory standards are in place to
limit arsenic levels in drinking water and protect public health. Regular monitoring and
appropriate water treatment are essential to minimize exposure and ensure the safety of the
drinking water supply.

Instructions for Chemical or Radiological MCLs Notice Tier 2
Template on Reverse Since exceeding chemical or radiological maximum contaminant levels (MCLs) is a Tier 2 violation, you
must provide public notice to persons served as soon as practical but within 30 days after you learn of the violation (R309-220-6(2)). You must issue a repeat notice every three months for as long as the violation persists. The Division of Drinking Water may have more stringent requirements for MCL violations; e.g., it may require you to provide water from an alternate source. Check with your agency to make sure you meet all requirements. Use the Fluoride MCL – Tier 2 template for fluoride MCL violations. Community systems must use one of the following methods (R309-220-6(3)):
Χ Hand or direct delivery
Χ Mail, as a separate notice or included with the bill
Non-community systems must use one of the following methods (R309-220-6(3)):
Χ Posting in conspicuous locations
Χ Hand delivery
Χ Mail
In addition, both community and non-community systems must use another method reasonably calculated to reach others if they would not be reached by the first method (R309-220-6(3)). Such
methods could include newspapers, e-mail, or delivery to community organizations. If you mail, post, or hand deliver, print your notice on letterhead, if available.
The notice on the reverse is appropriate for hand delivery or mail. However, you may wish to modify it
before using it for posting. If you do, you must still include all the required elements and you may not modify the mandatory health effects language (R309-220-8(4)).
Corrective Action In your notice, describe corrective actions you are taking. Do not use overly technical terminology when
describing treatment methods. Listed below are some steps commonly taken by water systems with chemical or radiological violations. Use one or more of the following actions, if appropriate, or develop
your own:
Χ We are working with [local/state agency] to evaluate the water supply and researching options to correct the problem. These options may include treating the water to remove [contaminant] or
connecting to [system]=s water supply.
Χ We have stopped using the contaminated well. We have increased pumping from other wells, and we are investigating drilling a new well.
Χ We will increase the frequency at which we test the water for [contaminant].
Χ We have since taken samples at this location and had them tested. They show that we meet the
standards. Repeat Notices
If this is an ongoing violation and/or you fluctuate above and below the MCL, you should give the history behind the violation, including the source of contamination, if known. List the date of the initial detection,
as well as how levels have changed over time. If levels are changing as a result of treatment, you can indicate this.
After Issuing the Notice
Make sure to send the Division of Drinking Water (PO Box 144830, SLC, UT 84114-4830)a copy of each
type of notice and a certification that you have met all public notification requirements within ten days after issuing the notice (R309-105-16(3)).
IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER
[System] Has Levels of [Contaminant] Above Drinking Water Standards Our water system recently violated a drinking water standard. Although this is not an emergency, as our customers, you have a right to know what happened, what you should do,
and what we are doing to correct this situation. We routinely monitor for the presence of drinking water contaminants. Testing results we
received on [date] show that our system exceeds the standard, or maximum contaminant level (MCL), for [contaminant]. The standard for [contaminant] is [MCL]. The average level of [contaminant] over the last year was [level]. or [Contaminant] was found at [level].
What should I do?
• You do not need to use an alternative (e.g., bottled) water supply. However, if you have specific health concerns, consult your doctor.
What does this mean? This is not an immediate risk. If it had been, you would have been notified immediately. However, [Insert relevant health effects language from Appendix B.] What happened? What is being done?
[Describe corrective action.] We anticipate resolving the problem within [estimated time frame]. For more information, please contact [name of contact] at [phone number] or [mailing address].
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.
This notice is being sent to you by [system]. Water System ID#: ___________. Date distributed:
