Lead in Water Test Results

Last Updated: 4/29/2019 7:38 PM

Please be advised the water testing program for the presence of lead in drinking water has been completed in all seven of our schools and in the Board of Education Offices.  Please review the letter below for detailed information regarding the test results.

Lead in Water Testing Results 


May 31, 2017


Dear Parents & Staff:

As you may be aware, districtwide sampling of the water in all seven schools and the Board of Education offices took place on Saturday, May 6, 2017. Results of the testing were received today and will be posted on the district website this afternoon.

The water sampling procedure was carried out by Agra Environmental and Laboratory Services in accordance with the technical guidance that was provided by the State of New Jersey. All drinking water and food preparation outlets were tested. All of the samples in Cedar Hill, Hilldale, Valley View, William Mason, Woodmont and Lazar Middle School tested below the lead action level established by the U.S. Environmental Protection Agency for lead in drinking water (15 µg/l [ppb]).

At MTHS there was one sample that tested above the lead action level - the drinking fountain in the Wrestling Gym. This fountain has been temporarily disabled until remedial measures can be completed.

At the Board of Education Office, the two fountains at the main entrance also tested above the lead action level. These fountains have been disabled. Bottled water is available in the kitchen area.

Our school system is committed to protecting student, teacher, and staff health. To protect our community and be in compliance with the Department of Education regulations, the Montville Township School Districttested our schools' drinking water for lead.

In accordance with the Department of Education regulations, the Montville Township School District will implement immediate remedial measures for any drinking water outlet with a result greater than the action level of 15 µg/l (parts per billion [ppb]). This includes turning off the outlet unless it is determined the location must remain on for non-drinking purposes. In these cases, a "DO NOT DRINK - SAFE FOR HANDWASHING ONLY" sign will be posted.

Results of our Testing

Following instructions given in technical guidance developed by the New Jersey Department of Environmental Protection, we completed a plumbing profile for the Montville Township High School. Through this effort, we identified and tested all drinking water and food preparation outlets.

Of the 29 samples taken at MTHS, all but 1 tested below the lead action level established by the US Environmental Protection Agency for lead in drinking water (15 µg/l [ppb]).

Of the 3 samples taken, all but 2 tested below the lead action level established by the US Environmental Protection Agency for lead in drinking water (15 µg/l [ppb]).


The tables below identify the drinking water outlets that tested above the 15 µg/l for lead, the actual lead level, and what temporary remedial action the Montville Township School Districthas taken to reduce the levels of lead at these locations.

In the coming weeks, we will be working on solutions to maintain a reduced lead level in these areas and conduct follow up testing. Only after appropriate remedial measures have been completed and follow up testing completed, will the drinking water locations be placed back into service.

Health Effects of Lead

High levels of lead in drinking water can cause health problems. Lead is most dangerous for pregnant women, infants, and children under 6 years of age. It can cause damage to the brain and kidneys, and can interfere with the production of red blood cells that carry oxygen to all parts of your body. Exposure to high levels of lead during pregnancy contributes to low birth weight and developmental delays in infants. In young children, lead exposure can lower IQ levels, affect hearing, reduce attention span, and hurt school performance. At very high levels, lead can even cause brain damage. Adults with kidney problems and high blood pressure can be affected by low levels of lead more than healthy adults.

How Lead Enters our Water

Lead is unusual among drinking water contaminants in that it seldom occurs naturally in water supplies like groundwater, rivers and lakes. Lead enters drinking water primarily as a result of the corrosion, or wearing away, of materials containing lead in the water distribution system and in building plumbing. These materials include lead-based solder used to join copper pipe, brass, and chrome-plated brass faucets. In 1986, Congress banned the use of lead solder containing greater than 0.2% lead, and restricted the lead content of faucets, pipes and other plumbing materials. However, even the lead in plumbing materials meeting these new requirements is subject to corrosion. When water stands in lead pipes or plumbing systems containing lead for several hours or more, the lead may dissolve into the drinking water. This means the first water drawn from the tap in the morning may contain fairly high levels of lead.

Lead in Drinking Water

Lead in drinking water, although rarely the sole cause of lead poisoning can significantly increase a person's total lead exposure, particularly the exposure of children under the age of 6. EPA estimates that drinking water can make up 20% or more of a person's total exposure to lead.


For More Information

A copy of the test results is available in our central office at each school for inspection by the public, including students, teachers, other school personnel, and parents, and can be viewed between the hours of 8:30 a.m. and 4:00 p.m. The results are also available on our website at www.montville.net. For more information about water quality in our schools, contact Mr. Steven Toth, Facilities Manager at 973-331-7100 ext. 2232.


For more information on reducing lead exposure around your home and the health effects of lead, visit EPA's Web site at www.epa.gov/lead, call the National Lead Information Center at 800-424-LEAD, or contact your health care provider.


If you are concerned about lead exposure at our school facilities or in your home, you may want to ask your health care providers about testing children to determine levels of lead in their blood.
