Instructions for Chemical or Radiological MCLs NoticeBTier 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)):

Hand or direct delivery
Mail, as a separate notice or included with the bill

Non-community systems must use one of the following methods (R309-220-6(3)):

Posting in conspicuous locations
Hand delivery
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:

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.
We have stopped using the contaminated well. We have increased pumping from other wells, and we are investigating drilling a new well.
We will increase the frequency at which we test the water for [contaminant].
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.
