Arsenic In Drinking Water

in Drinking-water

What Is Arsenic? Arsenic, a natural element of the earth's crust, is a poisonous heavy metal. In natural ground water, it may exist as trivalent, pentavalent, or a combination of both. Although both forms are potentially harmful to human health, trivalent is considered more harmful.

The Public's Greatest Exposure To Arsenic Is In Drinking Water, Where It Has No Color, Taste Or Odor.

How Does Arsenic Get Into Water Supplies? Arsenic enters our drinking water from natural, industrial and agricultural uses including mining, pesticides, atmospheric deposition, industrial releases, leaching from dumps & mining tailings, improperly disposed chemicals and natural leaching or erosion from rock. Arsenic contamination is common in groundwater wells.

Arsenic Is One Of The Most Toxic Substances Commonly Found In Drinking Water - There Is No Safe Level !

Health Concerns:According to a 2003 USPIRG report, arsenic can cause cancer, developmental, neurological, immune, & respiratory disorders, damage to internal organs, nerve function & arteries. National Academy Of Science (NAS) found that low levels of arsenic may be associated with increased risk of high blood pressure and the development of diabetes. The study found that arsenic harms the central & peripheral nervous systems, cardiovascular systems, damages the heart & blood vessels, & causes serious skin problems. Those especially vulnerable include: children, pregnant women, people with poor nutrition, those with HIV or AIDS, & those on chemotherapy.

  • Pregnant Women: While the placenta usually protects fetuses from chemicals, arsenic crosses the placental barrier. There is evidence it has adverse reproductive & developmental effects, including infant mortality, spontaneous abortions, stillbirths & premature births.
  • Children: Since they cannot quickly reduce arsenic in their blood, they are especially vulnerable. Many wooden play-sets have been built with chromated copper arsenate treated lumber.
  • Cancer: The NAS study found that chronic ingestion causes bladder, lung & skin cancer, and may cause kidney, liver, colon, & prostate cancer. They estimate 1 out of 100 people who drink water containing 50ppb, the current standard, will get cancer. As little as 3ppb carries a high risk of multiple cancers.

The Fact That A City May Meet The Federal Standard For Arsenic - Does Not Mean The Water Is Safe To Drink !

Regulations: Current EPA standard is 10ppb. A 10ppb standard goes against a vast amount of scientific information that support a 3ppb standard. NAS found that the new 2006 standard represents a lifetime fatal cancer risk 30x greater than what the EPA generally considers acceptable. There is no requirement that water providers tell consumers about levels of arsenic between 5-10ppb in their tap water. 4,000 public utilities will have a difficult time meeting the new 2006 arsenic standard. The California Office of Environmental Health Hazard Assessment has set the Public Health Goal (PHG) for arsenic at 4 parts per trillion(4ppt), a level in drinking water that would not be expected to pose a significant human health risk.

4-Year Comprehensive Study Shows - 1/4 Of Bottled Water Tested, Contained Arsenic!

Bottled water, which is often filtered tap water, is not necessarily any safer than tap water. Bottled water regulations are inadequate to assure consumers of safety, as certified testing for chemical contaminants is not required. NRDC's 4-year study of the industry, the most comprehensive independent testing of bottled water in the US, found that 1/4 of the waters tested contained arsenic.

There Is An Effective & Affordable Solution To The Arsenic Problem

Can I buy a water filter that will remove arsenic from my water? Yes, you should purchase filters only certified by NSF (800-673-6275 or nsf.org) The Multi-Pure 800 has been tested & certified by NSF to effectively reduce Arsenic V. It is the only carbon block filter in the U.S. to be certified by NSF for Arsenic.
