IN WELL WATER – SOME HELPFUL FACTS
Perchlorate is both a naturally occurring and man-made chemical. It is used
in a wide variety of industrial processes and pyrotechnics. Wastes from the
manufacture and improper disposal of perchlorate-containing chemicals are increasingly
being found in soil and water. It has been discovered in water in more than
20 states in the U.S. and has been found in water samples taken from wells
in Bergen County including Upper Saddle River.
Ingested perchlorate at sufficient levels interferes with the iodide uptake
into the thyroid gland, disrupting thyroid functions in adults and children.
While there is currently no standard for perchlorate, the New Jersey Department
of Environmental Protection recommends that people avoid drinking water known
through confirmed testing to contain more than 5ppb of perchlorate. Boiling
may increase the perchlorate concentration so cooking with water with a high
perchlorate level is not recommended, however, contaminated water is safe for
showering, bathing or washing clothes.
If you are concerned about possible perchlorate contamination, the DEP recommends
testing by a New Jersey certified lab. Typical water testing available through
the North West Regional Health Commission in Waldwick does not include perchlorate
testing. The DEP's Office of Quality Assurance offers a list of New Jersey
certified labs at http://www.state.nj.us/dep/pqa/index.html or by calling 1-609-292-3950.
