Disinfection Byproduct Levels Above Drinking Water Standards

Long Beach Water System (ID#48000) - Pacific County

Our water system has violated a drinking water standard. This situation does not require that you take immediate action; however, as our customers, you have a right to know what happened, what you should do, and what we are doing to correct the situation.

We routinely monitor for the presence of drinking water contaminants. Testing results we compiled from 2005 through 2007 show that our system exceeds the standard, or maximum contaminant level (MCL), for Total Trihalomethanes (TTHMs). The standard for TTHMs is 80 ug/L, while the average level ofTTHMs in our water system over the last year was 87.9 ug/L.

What should I do? You do not need to use an alternate (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, you must consider the following health risks: Total trihalomethanes - Some people who drink water containing trihalomethanes in excess of the MCL over many years could experience problems with their liver, kidneys, or central nervous systems, and may have an increased risk of getting cancer.

What happened? What is being done? At this time we've stopped using chlorine at the point where water enters our plant (pre-chlorination). In the past we used the pre-chlorination process to help keep our sedimentation basins algae free and as an oxidizer to remove color, iron, & manganese. This may not be the only part of the puzzle that has to change, therefore further observation & testing will be done. You, our customers, will receive notice each quarter on the progress that has been made. We anticipate resolving the problem within the next 60 to 90 days. The next follow-up letter will be in January of 2008, although we will continue to test daily.

We anticipate resolving the problem within 60 to 90 days. For more information, please contact Rick Gray 360-642-3163 or E-mail lbwtph2o@yahoo.com.
