Q: How will I know if my LMWD water is unsafe to drink or if there is a “boil order” ?

A:  How and when customers are notified about unsafe water is mandated by Federal and State laws, depending on type of contamination and possible health risk, so LMWD will follow those requirements.   We encourage you to read all correspondence from the District in a timely manner.  Notices can be included with your bill if the required notification meets the protocols for method of delivery and deadline for such notification.  These notices will describe what you should do and will help you determine if your health is at risk.  For example, if there were a serious health hazard, urgent public notices would be delivered in less than 24 hours by direct residential delivery.  It should be noted that boiling water cannot remove many types of contaminants, and could actually make the problem worse.  This is one of many reasons why it is important to read public notices if issued.

Q: How often is LMWD water tested?

A:  LMWD routinely monitors for many contaminants in your drinking water according to Federal and State laws.  An annual report summarizes testing and detections for each compliance period.   Violations and Formal Enforcement Actions, if any, are reported in each report.  We encourage customers to study the test standards and results, and to review related information from other independent sources. LMWD has reported many years of clean and safe water and this information can be found here:    https://www.lookoutmountainwaterdistrict.org/publications-and-records/drinking-water-quality-reports/

Q:   What about my water quality prior to the treatment process?

A:  A Source Water Assessment and Protection (SWAP) report provides a screening-level evaluation of potential contamination that could occur to source water, available from the State.  We use this and similar information to evaluate the need to improve our current water treatment capabilities and prepare for future contamination threats.

Q:  What should I do if I am unsure about something posted on social media or that I heard from my neighbor about my LMWD water quality?      

S Check your most recent correspondence from LMWD

S In case you overlooked a notification provided to you, you can check for recently posted notices at https://www.lookoutmountainwaterdistrict.org/category/news/

S Call or email the office to see if you missed an important recent notification LMWD does not currently use social media platforms for official correspondence

 

Q: What is LMWD doing about the recent “TTHM MCL” results? 

1) A Professional Engineer (P.E.) will evaluate and make recommendations to modify the treatment procedures, or distribution system, or both to reduce the likelihood that the Maximum Contaminant Level (MCL) will be exceeded once the plan is implemented.  Implementation timeline is not currently known, but is estimated at 12 to 16 months (possibly longer if construction is necessary).

2) Compliance testing will be done for the next quarter. Since this test calculates on a running average, even if the actual sample result is better (i.e. lower than the MCL), the 12 month average may exceed the MCL.  Notifications will be issued accordingly.

The recent notice included this information:  Some people who drink water containing trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys, or central nervous systems, and may have an increased risk of getting cancer.  You do not need to boil your water, use bottled water, or take other actions.  If you have an infant, severely compromised immune system, are pregnant, or are elderly, you may be at increased risk and should seek advice from your doctor about drinking this water. General guidelines on ways to lessen the risk of infection by bacteria and other disease-causing organisms are available from EPA’s Safe Drinking Water Hotline at 1-800-426-4791.
