MARINE CORPS BASE QUANTICO, Va. --
Levels of Total Trihalomethanes Above Drinking Water Standards
In keeping with National Primary Drinking Water Regulations, we are obliged to inform you that we may be in violation of state regulations because drinking water being served to our customers in the Quantico MCB Mainside system did not comply with Primary Maximum Contaminant Levels for total trihalomethnes.
We routinely monitor for the presence of drinking water contaminants. Testing results from 2nd quarter 2018 through 1st quarter 2019 show that our system exceeds the standard, or maximum contaminant level (MCL), for total trihalomethanes. The standard for total trihalomethanes is 0.080 mg/L. The average level of total trihalomethanes over this period at one of our four sample sites was 0.083 mg/L. Due to the rolling 12-month average levels repeatedly exceeding the PMCL, MCBQ has issued a contract to upgrade the Base’s water treatment system and it is expected to be in operation in 2019.
Even though this is not an emergency, as our consumers, you have the right to know what happened and what we are doing to correct this situation. There is nothing you need to do at this time. However, if you have specific health concerns, consult your doctor. This is not an immediate health risk. If it had been, you would have been notified immediately. You do not need to use an alternative (e.g. bottled) water supply. We continue to monitor and sample as required and consumers will be notified if there are any further issues. TTHMs are a by-product of drinking water disinfection by chlorination. It has been shown that some people who drink water containing TTHMs in excess of the PMCL over many years could experience problems with their liver, kidneys, or central nervous systems, and may have an increased risk of getting cancer. If consumers have any questions regarding the MCBQ drinking water system, they should contact the MCBQ POC listed below.
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.
