North Carolina School Finds Contaminated Drinking Water Perchlorate
“On Dec. 18, elevated levels of perchlorate were discovered in drinking water at Lake Norman High School in Iredell County, N.C. The Iredell-Statesville School Board has decided to provide bottled water to students and staff until further testing of the water quality is completed.
According to a press release, the school found that perchlorate levels at Lake Norman High School were particularly elevated compared to neighboring schools. While perchlorate levels are not regulated in North Carolina, the school system recognizes the risks and has opted to provide bottled water. The schools system hired an outside agency, Reliant Environmental, to test the district’s water quality following the discovery of elevated lead levels at a neighboring school.”

What is Perchlorate?
Perchlorate is a naturally occurring and manufactured chemical anion (ClO4-). Perchlorate occurs naturally in arid states within the southwestern portioin of the United States, nitrate fertilizer deposits in Chile, and deposits of clay deposits rich in potassium and sodium salts, i.e., potash ore, in the United States. It also forms naturally in the atmosphere by a photochemical interaction between chloride and ozone in the atmosphere . Perchlorate is commonly used as an oxidizer in rocket propellants, munitions, fireworks, airbag initiators for vehicles, matches, and signal/road flares. The primary source of perchlorate is man-made.
People are exposed to perchlorate primarily through eating contaminated food or drinking water and perchlorate dissolves in water. FDA perchlorate data can be found here.
The EPA has not yet established a maximum contaminant level goal for perchlorate and the intermim health advisory can be found here. Massachusetts adopted a drinking water standard for perchlorate of 2 µg/L, and California promulgated a revised standard of 1 µg/L. In addition, states may impose clean-up standards related to the quality and use of the groundwater aquifer.
Perchlorate can be removed using a number of advanced treatment technologies. Each technology has advantages and disadvantages depending on the level of perchlorate present in the source water, removal goals, other water quality parameters, competing treatment objectives, and treatment waste disposal options. Regenerable and single-pass ion exchange, reverse osmosis, and fixed- and fluidized-bed biological treatment can all remove perchlorate from drinking water sources.

A Water Quality Test Protects Against Contaminated Drinking Water
A Test on Water to Ensure Safety
Summary: Examining what you may be drinking in your water and why a water quality test on water is essential.
There is nothing more refreshing on a hot summer day than a cold glass of water. However, what if I told you that delicious glass of water could be making you sick? Yes, even water that tastes fine and looks clear may contain extremely harmful, dangerous microorganisms. While most people do not really think about having a water quality test completed for their water, it is most definitely an action you want to consider having done right away. Only information can protect you and your family, and if you know the data about the water you are drinking then you can take confidence in knowing whether your water is clean or poisoning you and your family.
Running a test on water is the best way to find out exactly what is in the water you and your loved ones are drinking. This can be done on any water source, even if you live in the city and water is provided through a water system. Although, there are some natural chemicals and minerals that are found in water that can be beneficial to us and are completely safe, there are also limits to the ingestible amounts found. If you drink the recommended water intake daily you need to be sure that you are drinking safe water.
A water quality test determines if there are any harmful bacteria in your water, such as total coliform, fecal coliform, E. coli., just to name a few. All of these harmful bacteria can cause you to become sick or make you susceptible to illness. There are some hazards in water that can even cause cancer and disease. While coliform bacteria is the least dangerous of the bacteria found in water, a large presence of it found in your water will lead to the need to test for other types of bacterium and contaminants. The others can cause sickness, including diarrhea, stomach cramps, low fever, vomiting, and more.
The last thing anybody wants is to end up getting sick from drinking water that they thought was completely safe. Running a test on water is important to guarantee you and your loved ones are drinking good, clean, safe drinking water. Have a professional come in and run the test for you. The reputable ones will be able to use a dependable, approved, trustworthy lab to run the test determining what is and is not in the water. It is recommended that you have your water tested routinely. Depending on the circumstances, yearly is advised, but some do test more often.
