	Is There Any Household Method to Neutralize Arsenic in Drinking Water? Help yourself to an AD-FREE life

The water Im going to be drinking within a month will be filled with it.

It does have relatively high levels of it though, 20-30 Parts Per Billion. The USEPA's maximum contaminant level is 10 Parts Per Billion.

quote: For water containing greater than 10 PPB of arsenic, but not greater than 50 PPB of arsenic: Some people who drink water containing arsenic in excess of the new MCL over many years could experience skin damage or problems with their circulatory system, and may have an increased risk of getting cancer.

Um, guys? We're talking parts per billion here.

Billion.

All the government's own site says is that you may have problems after many years of drinking the stuff.

I wouldn't worry.

Filtering seems to be the most common approach. Most sites refer to commercial applications or for wells.

One such example but includes a family possibility................

HOBOKEN, N.J. — Excessive arsenic in drinking water presents a major health hazard to millions of people in the United States and abroad. Arsenic, a carcinogen, is known to cause cancer and other serious health problems over time. Fortunately, engineers at Stevens Institute of Technology are on the leading edge of technology that can solve this insidious problem.
The Center for Environmental Engineering at Stevens has created patented technology for safely and effectively removing arsenic from drinking water. This technology has been developed on a large scale for water treatment plants and remediation sites, and on a low-cost, family-size scale for developing countries in crisis such as Bangladesh.


Stevens developed the Stevens Direct Coprecipitation Filtration process, successfully used in the United States for the removal of arsenic from contaminated groundwater and surface water since 1997. The DCF units can be installed in public water treatment plants as well as in groundwater remediation projects.

With changes in acceptable arsenic levels expected by the U.S. Environmental Protection Agency, applications for this technology are likely to expand considerably in the 21st century in the United States. Congress has required the EPA to finalize a new standard by 2001. The expected change will have a major impact on the nation’s water treatment plants and individual water wells throughout the country. Heightened awareness in countries worldwide also will likely lead to more widespread use of both large and small-scale technologies developed by Stevens.

In Bangladesh, naturally occurring arsenic leaches into aquifers in high concentrations, threatening the health as many as 70 million people who drink well water. Stevens is currently working to help the Bangladeshi government provide low-cost, family-sized filtration systems to everyone in that country who needs them.

MetalFilter, a new company under development at Stevens, is bringing the Stevens technologies to commercialization. For more information, contact Cass Bruton-Ward at the number near the top of this release, or Dr. George Korfiatis, professor and director of Stevens’ Center for Environmental Engineering at (201) 216-5326.

Rah's article refers to Floculation using FeCl3. Charcoal or activated Carbon typically only used for removing hydrocarbons so would not be applicable.

Perhaps ion exchange collumns might also work although I do not know if it will work to teh ppb levels mentioned above.

Reverse osmosis with the right sized semi-permeable membrane would also work. I doubt it would be feasible on the family home scale though.

Get a Britta or Pur filter. Your individual chance to get cancer from arsenic is very small. It's when it's spread across hundreds of millions of people that you see problems. Of course, if you're one of the statistics, sucks to be you.

It wasn't a vote. They undid the Clinton executive order lowering the amount of arsenic in drikning water in the 1st month of the first term of the Bush presidency. It was very contraversial at the time.

our drinking water has rocket fuel chemicals in it. Henderson used to manufacture rocket fuel for the space shuttle. Perchlorate is the name of the chemical. it has seeped into the ground and into Lake Mead, our source of drinking water.

Our case is a little different as the effects of perchlorate are not fully known, and it is difficult to put a limit on how much is allowable in drinking water.

Some metals as they have a small ion exchage filter as well. But according to this the best bet is a reverse osmosis filtration system for sepcifically removing obscure materiasl such as Arsenic.


Consumer Search

quote: Reverse osmosis These systems used to be popular, but since advances have been made among other filter types, reverse osmosis models are not recommended for most people. Part of the problem is that this process—which pulls water through a membrane--wastes about five gallons of water for every gallon of purified water produced. The filtering process is very slow compared to other methods. Nonetheless, reverse osmosis is very effective, and can filter out more obscure pollutants like arsenic. They are also adept with dissolved minerals such as iron.That makes them a good choice for well owners who may have such problems with their water. Reverse osmosis systems fit under the sink and require professional installation. Other filtering systems include distillation, which involves boiling water, allowing it to cool, and then filtering the collected sedimentation. Sediment filters help remove large particles like sand and silt. Reviewers generally do not discuss these types of filtering techniques.

It's been awhile since I looked at a Brita label, but memory says that they only remove copper and iron.

I'd recomend either reverse osmosis or steam distillation. Home units of either are available in the $300-500 range IIRC.

Tragically, this interpretation of events in Space's water supply is not supported by the facts.

1. Clinton's executive order came in the last days of his Presidency, so it wasn't as if he crusaded for this.
2. Clinton's executive order wasn't even supposed to go into effect until 2006. That's next year, btw.
3. Bush's proposal to rollback the executive orders was blocked in (the Republican held) Congress 218-189.
4. The EPA got into the act and made the 10 parts per billion standard official.
5. Of course, there wasn't a bit of evidence that said that the old 50 parts per billion standard was detrimental. But when did facts matter in government anyway?

Case closed. If Space is suffering from arsenic poisoning, it is not Bush's fault.

Now can we have one single goddamned discussion without ****ing politicizing it? Please?

Lastly I would like to point out that 30 ppb exceeds the standard in the US for the entire existence of the Republic. The idea of buying a purifier for water that is already pure is pretty damned silly. My grandmother drank WV well water for the first 40 years of her life and lived to see her 76th wedding anniversary.

It ain't the water that's gonna kill you, it's the worry.
