Notice of Standard Maximum Contaminate Level (MCL) Violation

Posted on Feb 26, 2019

IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER

Drinking Water Contains High Levels of Disinfection By-Products

NOTICE OF STANDARD MAXIMUM CONTAMINANT LEVEL (MCL) VIOLATION

 The Sugarloaf Water Association, PWSID: ME0091690, water system recently violated drinking water standards. 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 are required to monitor your drinking water for specific contaminants on a regular basis. The locational running annual average (LRAA) is determined by averaging all the samples collected at a particular monitoring location during the previous four calendar quarters. The LRAA standard for Haloacetic Acid 5 (HAA5) is 0.060 mg/L. Testing results for the 4th quarter of 2018 show that our system exceeded the maximum contaminant level for HAA5 when calculating the LRAA.

 The LRAA of HAA5 exceeded the MCL of 0.060 mg/L at our system’s sampling location.

The LRAA was 0.093 mg/L

What does this mean?

This is not an emergency.  If it had been, you would have been notified immediately. However, some people who drink water containing haloacetic acids in excess of the MCL over many years may have an increased risk of getting cancer.

 What should I do?

It is not necessary to use alternate water; however, if you have specific health concerns, please contact your health care professional.

Steps We Are Taking:

To protect drinking water from disease-causing organisms, or pathogens, we add chlorine to the drinking water as a disinfectant. Chlorine reacting with natural organic matter in the water can cause disinfection byproducts (HAAs) to form. As a first step, we are working with Wright Pierce Engineering to increase the removal of naturally occurring organic matter from our source water during the treatment process.

We are required to submit a plan to the Maine Drinking Water Program by 03/02/19, which will outline our progression of steps to resolve the problem.  This plan will include an engineering and operations evaluation of the treatment facility to resolve the problem.
