Does Lead Enter the Body Through the Skin or through Breathing?

Here’s a brief AI answer to the question with excellent reference notes.

According to multiple sources, lead does not enter the body through the skin during bathing or showering, even if the water contains lead¹²³⁴. The US Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC) agree that human skin does not absorb lead in water². Similarly, Health Canada states that lead will not enter the body through the skin or by breathing in vapors while showering or bathing³. The Massachusetts government also confirms that lead is not absorbed through the skin⁴.

However, it’s important to note that lead can enter the body if it is ingested. For example, you could accidentally swallow lead that is on your hands when you eat, drink, smoke, or apply cosmetics¹. Therefore, it’s always a good idea to wash your hands thoroughly after contact with lead-contaminated water.

The War Against Lead Pipes

In announcing a significant expansion of the federal government’s efforts under the Bipartisan Infrastructure Law to get “100% of lead pipes out of the nation’s water supply, once and for all,” the EPA estimated that there are still 9.2 million water supply pipes in the nation that contain lead. It noted that most of these pipes serve older homes.

The Chemical Industry Has Spent $110 million in Recent Months to Thwart Legislation to Control PFAS 

The US chemical industry likely spent over $110m during the last two election cycles deploying lobbyists to kill dozens of pieces of PFAS legislation and slow administrative regulation around “forever chemicals”, a new analysis of federal lobbying documents has found.

The industry’s onslaught was effective: only eight pieces of legislation that targeted PFAS made it through Congress, the paper prepared by the Food and Water Watch (FWW) nonprofit found.

“There’s an extreme amount of money that’s going into fighting [PFAS legislation],” said Amanda Starbuck, FWW’s research director and the lead author on the report. “It’s hard to win these fights when there’s so much funding being put in from the opposing side.”

PFAS are a class of about 14,000 compounds used to make products resist water, stains and heat. They are known as “forever chemicals” because they do not naturally break down, and they have been linked to cancer, high cholesterol, liver disease, kidney disease, fetal complications and other serious health problems.

As the dangers from PFAS have come into sharper focus over the last decade, lawmakers, the Environmental Protection Agency and other administrative agencies have come under an ever-increasing amount of pressure to rein in the chemicals use and clean up pollution. Chemical manufacturers’ spending has jumped in response, the report noted

“The chemical and associated industries are powerful and have used their army of lobbyists and campaign finance war chests to thwart meaningful action,” the paper states.

Measuring PFAS

A major problem in enforcing the EPA’s proposed new 4 parts per trillion limit on the “forever chemicals” is that instrumentation capable of measuring an amount that small is hard to find and very expensive. A practical solution may be to raise the allowable a bit to an amount that city water suppliers can measure. The lesson here is that all EPA allowables are based on science that has been negotiated to meet the realities of the world we live in. 

Nitrates in Wells in Eastern Oregon

High levels of nitrates that are getting worse by the year are making the water impossible to drink in rural areas of Eastern Oregon.”Thousands of Oregonians in Umatilla and north Morrow counties rely on private wells for drinking water, tapping into a massive underground aquifer. But pollution has steadily contaminated that groundwater source in recent decades, turning what was once safe water into a potentially toxic supply.” KGW8 News.

That’s not really debatable anymore.’’  Capitol Media Services.

Fraudulent Claims Are Disrupting Camp LeJeune Damage Payouts

According to Bloomberg News, “The government plan to pay billions of dollars to victims of toxic water at Camp Lejeune has unleashed a wave of fraudulent claims that threatens to disrupt or taint what could be one of the largest-ever mass tort cases.  Veterans’ advocates and lawyers also say the fake claims — and the time and effort to identify and weed them out — could dilute the empathy for legitimately ill victims and slow the process of compensating them.”  Water Online.

Lithium

Lithium, an unregulated water contaminant, was found in surprisingly high occurrence levels in ongoing EPA monitoring. In fact, 22% of the community water supplies tested exceeded the the EPA’s established health reference level.

According to a recent Water Quality Association (WQA) statement, “The health implications of lithium in drinking water are still being studied, and they may not all be negative. In the pharmaceutical industry, lithium is used as an antidepressant, and some studies have correlated high lithium levels in drinking water with a reduction in suicide rate. A study in Denmark had conflicting results: High levels of lithium in drinking water were correlated with a decreased risk of dementia, but medium levels of lithium in drinking water correlated with an increased risk of dementia. A study in Argentina found that high levels of lithium can interfere with child development by making it difficult for pregnant women to maintain healthy calcium levels in the blood.”

The WQA reaches the familiar conclusion: “More studies are needed.”

In the meantime, if you want to remove lithium from your drinking water, an undersink reverse osmosis unit is the best way to go about it.

Can’t Open the Filter Housings on Your Undersink Water Filter or Reverse Osmosis Unit?

1. The first thing of all is relieve the pressure on the housings.  With a filter, turn off the inlet water and open the faucet.  Leave it locked open while you work.  If you have a reverse osmosis unit, also turn off the valve on the storage tank. When no water is coming from the faucet, you should be able to open the housing.

2. To open, turn the housing counterclockwise.  Think of it this way: If you put the filter wrench on the extreme right housing and point the handle away from the housing to the left, you would use your right hand and pull back toward your body to open the housing.

3. Get into a comfortable position. If the unit is installed in an awkward, hard-to-reach location, you may have to pull it out to a place where you can address it comfortably. In the worst case, you may have to uninstall it so you can lay it on its back to get more leverage.  (Remember that the housings are full of water, so it’s going to run on the floor when it opens if it’s lying sideways.)

4.If all else fails, you can get more leverage by lengthening the wrench handle with a pipe or a vacuum cleaner wand.  Or you can even buy a special wrench designed for very tough jobs.  See WR012 on this page.

5. Extreme methods: Someone suggests using a hair dryer to warm the filter cap causing it to expand and thus loosen more easily.  Another suggestion, and I’ve seen this work with larger housings, is to apply the wrench to the housing and tap on the wrench handle with a small hammer or rubber mallet. The shock from the mallet tapping can break the housing loose and let you open it.

6. Finally, this may sound strange, but it is important.  When you apply steady pressure to the wrench to loosen the housing, believe that it will open.  In fact, think about what it will feel like when it breaks loose and opens.

EPA Declares War On TCE

On October 23,  the U.S. Environmental Protection Agency (EPA) announced a proposal to ban all uses of trichloroethylene (TCE), an extremely toxic chemical known to cause serious health risks including cancer, neurotoxicity, and reproductive toxicity. TCE is used in cleaning and furniture care products, degreasers, brake cleaners, and tire repair sealants, and a variety of safer alternatives are readily available for many uses. This action, taken under the Toxic Substances Control Act (TSCA), would protect people from these health risks by banning the manufacture, processing, and distribution of TCE for all uses.

The toxicity and dangers of TCE have been known for many years and the EPA’s action is long overdue. EPA found that TCE causes liver cancer, kidney cancer, and non-Hodgkin’s lymphoma. It also causes damage to the central nervous system, liver, kidneys, immune system, reproductive organs, and is dangerous for fetal development. These risks are present even at very small concentrations of TCE.The best protection for homes and businesses against TCE are carbon filtration and reverse osmosis.

Encroaching water from the Mississippi River has necessitated more thorough disinfecting, which leaves behind dangerous chemicals

The water for a community along Louisiana’s Gulf coast has seen a significant increase in the levels of contaminants known as disinfection byproducts, according to recent state water tests reviewed by the Guardian. According to the Environmental Protection Agency (EPA), long-term exposure to such substances poses an increased risk of cancer.

The findings have emerged as many residents along Louisiana’s southern coast have faced saltwater intrusion from the Gulf of Mexico.

Since early summer, the combination of drought and rising sea levels has helped drag salty water from the ocean up the Mississippi River. The high levels of saltwater have made much of the region’s water undrinkable. But public health experts have also voiced worries that the saltwater intrusion could, over time, corrode the region’s ageing water infrastructure, leach heavy metals into the drinking water and create other knock-on problems.

Faucet Adapters for Countertop Filters

As sink faucets get more diverse, it is getting harder to install water filters that get their water from the sink faucet. Among our standard products, our Model 77 countertop and our countertop reverse osmosis units are most often connected to the sink faucet for their water source.  Ideally (but increasingly rarely) the faucet’s aerator is removed and the filter’s diverter valve screws right on to the threads on the faucet.

If the diverter doesn’t match the faucet (all diverters are the same, but faucets can vary a lot), an adapter is used to make the connection.

The diverter valve from the filter screws directly to the sink faucet. If it doesn’t fit, there are many adapters available to make the connection. 

We provide the two most standard diverter adapters with our new units, but if these don’t work, the best plan is to buy an inexpensive pack of the most commonly used adapters.  We don’t sell adapters other than the two most common, but a customer suggested a really good Amazon source.  Their basic adapter pack should work with almost any faucet. See link below.
