No amount of lead in drinking water is safe. I have been saying for many years that USEPA standards for contaminants in water are a political compromise.
Just because your water meets EPA standards (MCL) does not mean the water is ‘safe’. The standards start out with an orientation toward health. In other words, EPA looks for contaminants in water that can negatively affect your health. But then when they establish that standard they must consider the cost of forcing every water system in the country to meet that standard.
Joel Beauvias, the deputy assistant administrator for the EPA’s Office of Water, said the agency has “consistently said that no level of lead is safe.” But, he explained, the agency has to set limits that can be reasonably achieved.
The final MCL, or maximum contaminant level, established by EPA ends up being a compromise between health and cost. If you want to eliminate a particular contaminant, and I certainly suggest that you do, then you must do that on your own.
Here is an interesting article which cites EPA sources agreeing with my assessment about lead in drinking water: Continue reading
Finally a good article for consumers about the pros and cons of various types of whole house carbon filters.
This article is so good I decided to share it with you right away.
There is a brief discussion of chloramine and its disinfection byproducts, which differ from those of chlorine yet are also toxic to humans.
This is useful information if you have chloramine in your water.
Next the article talks about the pro and cons of various whole house carbon filters.
Is Las Vegas water safe to drink?
Here’s an aricle by the Las Vegas Review Journal in response to the Las Vegas Valley Water District releasing its annual Water Quality Report about drinking water in Las Vegas.
Bascially the article says that Las Vegas drinking water is safe in spite of the presence of uranium. Read more here: Continue reading
I’ve been saying for quite some time now that I am not comfortable with USEPA’s maximum allowable level of nitrates in drinking water. This amount is known as the Maximum Contaminant Level or MCL in your water report.
Yet another study has come out which finds a causal relationship between nitrates in drinking water at just half of the MCL and bladder cancer in post menopausal women.
You can read a synopsis of that study here: Continue reading
Yet another study of pharmaceuticals in streams has disturbing results.
‘A team of researchers, led by hydrologist Paul Bradley, recently collected water samples from 59 small streams in the Southeast… All 59 streams tested positive for at least one of compounds and the overall average was six different compounds per stream.
“Pharmaceutical contaminants are growing aquatic-health concerns and largely attributed to wastewater treatment facility discharges,” the study says. But only 17 of the 59 streams have any reported wastewater discharges.’ You can find information on the study here:
The notion of whether or not your chlorinated tap water is ‘healthy’ for you to drink is an intriguing question. USEPA regulates the level of contaminants which can be present in tap water. As long as those contaminants fall below the EPA Maximum Contaminant Level (MCL), the water is deemed to be acceptable. But what does acceptable mean? Does it mean the water is generally safe for healthy individuals? Does it mean the water is healthy to drink?
I don’t think there is a clear answer to this question. My opinion was reinforced recently when I came across this article: Chloramines in Water. The author, a former head of USEPA drinking water standards division says this in the article, Continue reading
I’ve been getting a lot of calls lately about PFOA, or perfluorooctanoic acid, an ingredient in Teflon. Apparently DuPont used this toxic ingredient and it has ended up in the water supplies of a number of cities. Most of my calls are coming from Montclair, NJ.
This is an interesting article about how a local farmer discovered the toxicity of this chemical and DuPont’s disposal methods when his cattle started dying: Continue reading
Round Up in Drinking Water Linked To…
Kidney and liver damage.
Do you live near fields of corn and beans? If so you may be drinking glyphosphate, aka Roundup. A tecent study performed on rats resulted in kidney and liver damage.
‘Long-term exposure to tiny amounts of Roundup—thousands of times lower than what is permitted in U.S. drinking water—may lead to serious problems in the liver and kidneys, according to a new study.’ Continue reading
The other day a woman wrote me and said she wanted the purest water possible at every faucet in her house. “No you don’t”, I said.
What’s the difference between purified water vs filtered water? Words have certain technical meanings in the water treatment world but of course consumers don’t know this. And not knowing you can be asking for the wrong things when you start your search for a water treatment system for your home. This can cost you money. More importantly it can simply lead you astray as you waste time searching for the wrong thing. Continue reading
