Arsenic In Drinking Water: Exposure, Toxicity, Removal By Water Filters

Arsenic In Drinking Water: Exposure, Toxicity, Removal By Water Filters

We do everything from providing in-depth breakdowns of common contaminants to reports on city tap water quality. We’re keeping it going by writing about another common heavy metal that can contaminate drinking water: Arsenic.  

How Are We Exposed To Arsenic?

Humans are exposed to inorganic arsenic mainly through contaminated drinking water. Some water sources in the United States have higher naturally occurring levels of inorganic arsenic than other regions. Levels of inorganic arsenic in soil typically range from 1-40mg/kg and the EPA recommended concentration in water supplies is less than 10µg/L. However, higher levels can occur near natural mineral deposits, mining sites, smelting industries, and regions where pesticides have been applied.

In addition, workers who use arsenic compounds for smelting, pesticide manufacturing and application, and wood preservation are at a higher risk for arsenic poisoning.  

Below is a map published by the United States Geological Survey (USGS) which shows the concentration of arsenic in groundwater in the United States.  If you live in one of the areas with high arsenic concentration, and get your drinking water from a private well, we highly recommend getting your water tested by a qualified laboratory

Arsenic Toxicity

Arsenic is a toxic heavy metal several epidemiological studies have reported a strong association between arsenic exposure, cancer, and systemic diseases. In fact, arsenic exposure affects virtually all organ systems including the cardiovascular, dermatologic, nervous, hepatic, renal, gastrointestinal, and respiratory systems. The severity of the adverse health effects is related to both the chemical form of arsenic and the dosage. Evidence of carcinogenicity due to arsenic exposure is very strong, but the specific mechanism by which it causes cancer is not completely understood.

What Can I Do To Reduce My Exposure To Arsenic?

A growing number of people are realizing that regulatory limits are not always in line with current toxicological studies, and are taking steps to minimize expsoure to heavy metals like arsenic, lead, mercury, and chromium 6 from their drinking water, even if their city is "in compliance" with EPA regulations.   

Unlike lead, which leaches into water from pipes, arsenic comes from the source water itself, so flushing pipes or replacing plumbing will not reduce arsenic concentrations. Boiling water also does NOT remove arsenic.  Arsenic must be removed using a water filter that is specifically designed to do so.  

Whole House Filters

Some whole house filters can be configured to remove arsenic to some degree.  We do not typically recommend these systems becasue they are very expensive, and there's no need to filter the water that is used for most household applications (e.g. flush toilet).  We strongly believe that point of use water filters are the appropriate tool for the job.

Point Of Use Water Filters For Arsenic

The most cost-effective method of arsenic, chromium 6, and contaminants filtration is through a point of use water filter.  When shopping for these systems, we encourage you to make sure that the filter actually filters arsenic (most don't).  While we believe that our advanced under sink filters have unique benefits and use filtration media that effectively remove both types of inorganic arsenic, some systems that use reverse osmosis can be a good choice for people who are willing to accept the downsides.  No matter what... make sure that your filter removes what you think it does!

As always, feel free to take advantage of our “help no matter what” approach to technical support!  While we do make water filters that remove arsenic, our water nerds are happy to answer your questions about the effects of arsenic in water, even if you have no intention of purchasing a Hydroviv Water Filter.  Reach out by dropping us an email (hello@hydroviv.com) or through the live chat on our webpage.

Digging Into The Environmental Working Group Tap Water Database

Digging Into The Environmental Working Group Tap Water Database

Eric Roy, Ph.D.  |  Scientific Founder   

This past week, the Environmental Working Group (EWG) released a website where people punch in their zip code, and view contaminants found in their water.  As a company that uses water quality data to optimize each customer’s water filter, we applaud EWG for putting in the enormous amount of time & effort to build the database so the public can learn about their water.  Unfortunately, we are seeing that these data are being used to generate inflammatory headlines, which can leave consumers confused and unnecessarily panicked.   

We will be updating this water quality database blog post as more questions come in. If you have your own question, please reach out to us (hello@hydroviv.com).  One of our water nerds will do their best to get back to you very quickly, even if it’s outside of our business hours.

Frequently Asked Questions 

Updated July 31, 2017

Are All Potential Contaminants Listed In The EWG Tap Water Database?  

No.  The EWG Tap Water Database pulls data from municipal measurements, but municipalities are only required to test for certain things.  Simply put, you can’t detect what you don’t look for.  One example of this can be seen by punching in Zip Code 28402 (Wilmington, North Carolina) into the EWG Tap Water Database.  GenX, a chemical that has been discharged into the Cape Fear River by Chemours since PFOA since 2010, is not listed, even though it’s been in the center of a huge topic of conversation for the past 2 months in the local media.

Why Is The “Health Guideline” Different Than The “Legal Limit?”

The two different thresholds use different criteria.  For example, the “Health Guideline” cited by EWG for carcinogens is defined by the California Office of Environmental Health Hazard Assessment (OEHHA) as a one-in-a-million lifetime risk of cancer, while the “Legal Limit” refers to the MCL which is the limit that triggers a violation by EPA.  The OEHHA's criteria are established by toxicological techniques, while the EPA limits are negotiated through political channels.  We wrote an article that addresses this topic in much more detail for those who are interested.

Why Am I Just Learning About This Now?

The EPA's Safe Drinking Water Act requires municipalities to make water quality test data public in Consumer Confidence Reports.  These reports are required to talk about the water's source, information about any regulated contaminants found in the water, health effects of any regulated contaminant found above the regulated limit, and a few other things.  As discussed before, the data in the EWG report use different criteria than the EPA, and it's hard for people to make sense of what's what.  

Are The Data Correct If My Water Comes From A Private Well?

No.  The EWG Tap Water Database only has data for municipal tap water.  Private wells are completely unregulated, and there's no requirement to conduct testing.  If you'd like us to dig into our additional water quality databases to help you understand likely contaminants in your private well, we're happy to do so.  We don't offer testing services, but we're happy to help you find an accredited lab in your area, give advice on which tests to run, and help you interpret the results!  We offer this service for free.

Heavy Metal Toxicity & Contamination:  What You Need To Know

Heavy Metal Toxicity & Contamination: What You Need To Know

What Are Heavy Metals?  

Chemists categorize heavy metals as elements that are at least five times denser than water. Examples of heavy metals include: cobalt (Co), copper (Cu), chromium (Cr), iron (Fe), magnesium (Mg), manganese (Mn), molybdenum (Mo), nickel (Ni), selenium (Se), zinc (Zn), arsenic (As), mercury (Hg), and lead (Pb). Some heavy metals are essential minerals for healthy biochemical and physiological function. Others, such as lead, chromium, arsenic, and mercury are toxic even when ingested in very small quantities. Elemental density and toxicity are inter-related. Arsenic, which is technically categorized as a metalloid (think of a metalloid as metal-like), is quite dense and is extremely toxic in very small quantities. Thus, toxicologists typically categorize arsenic as a heavy metal.  Due to their shared high degree of toxicity, lead, cadmium, chromium, mercury, and arsenic are cause for significant public concern.

How Are We Exposed To Heavy Metals?

People can be exposed to heavy metals though ingestion, inhalation, or contact with skin. The severity of health effects of heavy metals is related to the type and chemical form of each particular contaminant, and is also depends on the exposure time and dose.

Heavy metals have industrial, domestic, agricultural, medical and technological applications, and as a result they are now widespread in our environment. Heavy metal pollution in water is very high in areas where mining, smelters, metal processing refineries, wood preservation, and paper processing facilities are located. Human exposure to heavy metals as well as public concern for the associated health risks have both risen dramatically as a result of an exponential increase of their use in these various applications.

If Heavy Metals Are Toxic, Why Are They Found In Multi-Vitamins?

Some heavy metals including cobalt (Co), copper (Cu), chromium (Cr), iron (Fe), magnesium (Mg), manganese (Mn), molybdenum (Mo), nickel (Ni), selenium (Se) and zinc (Zn) are essential minerals that are necessary for various biochemical and physiological functions.  They serve as components of several key enzymes and play important roles in various oxidation-reduction reactions in our bodies. Many of these metals are found naturally in the food we eat, while other foods are fortified with these minerals. For example, almost all and grain products (cereal, bread, crackers, etc) are fortified with iron. Inadequate supply of these minerals can result in a variety of deficiency diseases. For example, anemia (red blood cell deficiency) can result from low iron. Supplements can prevent or treat diseases resulting from mineral deficiency.

Not all heavy metals are toxic at in low quantities, however all heavy metals (yes, even the good ones) can be toxic if too much is ingested. Each heavy metal’s toxicity depends on dosage, method of exposure, age, gender, genetics, and nutritional status of the exposed individual. An excess amount of any particular heavy metal produces cellular and tissue damage leading to a variety of adverse effects and human diseases. For some including chromium and copper, there is a very narrow range of concentrations between beneficial and toxic effects, so be careful when taking supplements. Other metals such as aluminium (Al), antinomy (Sb), arsenic (As), barium (Ba), beryllium (Be), bismuth (Bi), cadmium (Cd), gallium (Ga), germanium (Ge), gold (Au), indium (In), lead (Pb), lithium (Li), mercury (Hg), nickel (Ni), platinum (Pt), silver (Ag), strontium (Sr), tellurium (Te), thallium (Tl), tin (Sn), titanium (Ti), vanadium (V) and uranium (U) have no established biological functions and are considered non-essential metals in our diet.

What Is Heavy Metal Toxicity Or Heavy Metal Poisoning?

Each metal differs in how it behaves in our bodies, and exposure alone does not always cause disease or harm. Heavy metal-induced toxicity and carcinogenicity involves many biochemical processes, some of which are not clearly understood. The human body’s natural response to heavy metal exposure is to store them and slowly excrete them over time to minimize organ damage.

Acute heavy metal poisoning usually occurs when people are exposed to large amounts of one particular metal at a time. For example, a child swallowing a lead bullet can cause a large amount of lead exposure all at once. Acute exposures can quickly cause serious health effects or death.

Chronic or long-term exposure to lower levels of heavy metals can also cause health problems. The symptoms of chronic heavy metal poisoning can be severe, but are often less obvious and develop much more slowly over time than the symptoms caused by acute exposure. This is a topic of growing scientific evidence that needs to be better researched to clarify all the possible health implications. Chronic heavy metal poisoning can be challenging for both health care providers and patients because there are often many more questions than answers. Symptoms of chronic heavy metal toxicity can include but is not limited to headaches, fatigue, muscle and joint pain, and weakness. However, these same symptoms can be caused by many other health problems unrelated to heavy metal toxicity. True chronic heavy metal poisoning is rare but also difficult to diagnose.

What Are The Health Effects Of Heavy Metal Toxicity?

Even in very low quantities, lead, cadmium, chromium, mercury, and arsenic are known to induce cardiovascular diseases, developmental abnormalities, neurologic and neurobehavioral disorders, diabetes, hearing loss, hematologic and immunologic disorders. These heavy metals are also classified as human carcinogens (known or probable) according to the U.S. Environmental Protection Agency, and the International Agency for Research on Cancer.

Although the acute and chronic effects are known for some metals, little is known about the health impact of mixtures of heavy metals. Studies have shown that toxic heavy metals can interfere with absorption and use of nutritionally essential metals such as iron, calcium, copper, and zinc. However, the research on the combined effects of heavy metal exposure is very limited.

How Can I Minimize Exposure To Heavy Metals?

The best way to reduce heavy metal pollution is prevention. Identify sources of heavy metals in your home and remove them. Here are some helpful suggestions:

  • Be aware of local fish advisories for mercury contamination.
  • Test the water in your home for heavy metals and install a home water filtration system if necessary.
  • Read labels on products coming in to your home.
  • Store products containing heavy metals out of reach of children.

How Is Drinking Water Regulated?

The Environmental Protection Agency (EPA) sets regulatory limits for over 90 contaminants in water provided by public water systems.  The EPA sets these limits in accordance with the Safe Drinking Water Act to protect public health in the communities that are using this water. The EPA limits are divided into two main categories.  National Primary Drinking Water Regulations are legally enforceable standards that apply to public water systems. Primary standards protect public health by limiting the levels of contaminants in drinking water that negatively affect human health. National Secondary Drinking Water Regulations are non-enforceable guidelines regulating contaminants that may cause cosmetic effects (such as skin or tooth discoloration) or aesthetic effects (such as taste, odor, or color) in drinking water. EPA recommends secondary standards to water systems but does not require systems to comply. In addition to the federal EPA standards, The Safe Drinking Water Act (SDWA) gives individual states the opportunity to establish their own drinking water standards if they are not more lenient than those set by the EPA's national standards.

So how do these federal and state regulations effect private well-owners?  These same limits and guidelines used for public water are also adopted by most institutions and lenders for home water testing as a way to determine if the property provides potable, safe water. When a home goes up for sale, if the buyer is financing, they will likely be required to test the water. While lenders may be concerned about a potable water source in order to protect their investment, there are no official rules or regulations for determining potability of private wells. Many states and towns do not even require sampling of private wells after installation. It is the responsibility of the homeowner to maintain their well and water supply. 

How Often Should Home Water Testing Be Conducted?

Private well water should be tested a minimum of once per year. Drinking water supplies obtained from shallow dug wells and surface water sources should be tested more frequently as they are more susceptible to contamination. Annual testing of both dug and drilled wells should check for the most common contaminants which are bacteria, nitrates and nitrites. Even if your water has consistently been safe to drink in the past these parameters could change without you knowing and affect the safety of your water. New drilled wells should be tested with a more comprehensive water test which includes bacteria, nitrates, nitrites, metals, minerals and radon. This test identifies many common primary and secondary contaminants typically found in the bedrock surrounding the well.  This comprehensive test should be repeated every 3 – 5 years to ensure the well is still providing safe water.

What Are The Most Common Types Of Drinking Water Contaminants?

Drinking water contaminants can be divided into several categories: Inorganic Chemicals, Organic Chemicals, Radionuclides and Microorganisms. Testing for every possible analyte would be prohibitively expensive but we have put together a comprehensive test package which covers common problems found in our area.  

Total Coliform

E.coli

pH

Nitrate-N

Nitrite-N

Copper

Iron

Manganese

Lead

Arsenic

Hardness

Magnesium

Calcium

Chloride

Fluoride

Uranium

Sodium

Radon

 

 

 

Laboratories throughout the United States will offer similar packages based on the geology in their area.

What Is The Process For Analyzing Drinking Water?  

The process of analyzing drinking water varies by laboratory and their methods used.  However, the basic premise is the same for all of them.  The first step is to obtain a water test kit from the certified drinking water laboratory that you intend to use for the analysis.  Home water testing kits are specific to each laboratory and their methods so it is important not to use another laboratory’s bottles. These test kits come with all the information that is needed to collect the sample and get it back to the laboratory in the required time frame.  The sampling instructions are usually step by step and easy to follow. Once the water is received by the laboratory it will be analyzed for the requested parameters and report will be generated and sent back to the client. The typical turn-a-round time for a comprehensive water test is 2-3 business days.  

Using a certified laboratory is very important.  They are monitored by their state and undergo periodic inspections to ensure that they are producing the highest quality data. During these inspections their instruments, standard operating procedures, lab technicians, quality control documentation and reporting procedures are reviewed and evaluated. If anything is found to be out of compliance certification for the laboratory can be revoked.  In addition to inspections, they also have to complete proficiency tests for each method they conduct to prove that they can perform the method properly and obtain results within the specified limits.  

What Are The Risks Associated With Consuming And/Or Using Contaminated Water?

The risks vary greatly depending which contaminants you have in your water. Common health effects include gastrointestinal illness, reproductive problems, neurological disorders and cancer.  These health problems pose a greater threat to young children, pregnant women, the elderly, and people with compromised immune systems.  The health effects of drinking contaminated water can range from no physical impact to severe illness or even death.

Some of the effects of drinking contaminated water are known almost immediately. Immediate health related issues generally stem from contamination by pathogens such as total coliform and E.coli.  Symptoms include gastrointestinal and stomach illnesses such as nausea, vomiting, cramps, and diarrhea.  

Other contaminants pose health effects that may not be observed for many years.  Some of the most common ones are:

Arsenic in water occurs naturally as well as from industrial activities. Studies have shown that chronic or repeated ingestion of water with arsenic over a person’s lifetime is associated with increased risk of cancer (of the skin, bladder, lung, kidney, nasal passages, liver or prostate) and non-cancerous effects (diabetes, cardiovascular, immunological and neurological disorders).

Lead can occur due to corrosion of lead containing household plumbing and by industrial pollution. Major toxic effects include anemia, neurological dysfunction/damage and renal impairment.

Uranium is a tasteless, colorless, odorless contaminant. Drinking water with uranium amounts exceeding 30ug/L can lead to increased cancer risk, liver damage, or both.

Copper has both long term and short term effects. Some people with short term exposure, experience gastrointestinal distress, and with long-term exposure may experience liver or kidney damage. It is typically introduced into the water from household plumbing systems.

Fluoride has been shown to reduce tooth decay in children's teeth if they receive an adequate level. The optimal concentration, as recommended by CDC is approximately 1.1 mg/L. In the range of 2.0-4.0 mg/L of fluoride, staining of tooth enamel is possible. Above 4.0 mg/L, studies have shown the possibility of skeletal fluorosis, as well as the staining of teeth.

Radon is the second leading cause of lung cancer. High levels of radon gas occur naturally in Maine soil and water, and can move up into a house from the ground. The house then traps the radon in the air inside. Radon gas can also dissolve into well water, which is then released into the air when you use the water.

What Should I Do If The Laboratory Finds Something In My Water?

If tests on your water indicate problems, the next step is to determine what type of system you need to treat the water. This can be a difficult decision because there is a wide variety of water treatment devices on the market today. Water purifiers range from relatively low-cost, simple filter devices for a kitchen faucet to more expensive, sophisticated systems that treat water from its point of entry into a home. Keep in mind, no one water treatment device can solve every problem.

5 Things To Know About Arsenic In Drinking Water

5 Things To Know About Arsenic In Drinking Water

Eric Roy, Ph.D.  | Scientific Founder  

There has been some recent press coverage about arsenic contamination in drinking water.  Predictably, our email and support line have been filled with questions on the topic.  While we have written other articles in the past about well water in general, the purpose of this article is to specifically answer FAQs about health effects of arsenic in drinking water, and to dispel some myths about arsenic in drinking water.

Why Should I Care About Arsenic In Drinking Water?

Arsenic is a toxic substance that is linked to a long list of health problems in humansFor example, arsenic can cause a number of different cancers (e.g. skin, bladder, lung, liver, prostate), as well as create non-cancerous problems with cardiovascular (heart/blood vessels), pulmonary (lungs), immune, neurological (brain), and endocrine (e.g. diabetes) systems.  Simply put, the health effects of arsenic in drinking water are bad news, and you can't see, taste or smell it in water.

What Are The Different Types Of Arsenic Found In Drinking Water?

Nearly all arsenic found in drinking water is inorganic.  There are two types of inorganic arsenic, Arsenic(III) and Arsenic(V), and both are toxic.  The ratio of the two forms depends on what part of the country you live in, and whether or not your water is chlorinated, becasue chlorine quickly converts Arsenic(III) to Arsenic(V).  

How Does Arsenic Contaminate Drinking Water?

While arsenic-containing pesticides can contaminate water, most arsenic contamination comes from the area's natural geology.  This means that arsenic can contaminate seemingly pristine water in certain parts of the country, including private wells.  The map below is from USGS and shows arsenic groundwater concentrations.  In this map, you can see prevalent arsenic hot spots in places like Maine, Wisconsin, Texas, and various areas across the western part of the US.

Map Of Arsenic Concentrations In Groundwater

How Much Arsenic Is Toxic?

EPA acknowldeges that there is no safe level of arsenic for drinking water (MCLG = 0), but has set a regulatory limit of 10 parts per billion (ppb) for arsenic in drinking water.  When this level was negotiated, scientists were pushing for a 3 ppb, but ultimately EPA decided that the cost of lowering the allowable level to 3 ppb would "not justify the benefits."  We recently wrote a dedicated article on how EPA determines acceptable levels of contaminants in drinking water that you can read if you would like more information on this topic.

It's also worth pointing out that a large number of people in the US draw water from private wells, and that most well water "checks" do NOT test for arsenic.  If you live in an area on the map with hot spots, we highly recommend getting arsenic testing done by a qualified water testing lab.  Test kits from hardware stores are not accurate, and cheap TDS meters and "water testers" tell you nothing about arsenic. 

What Can I Do To Reduce Exposure To Arsenic?

A growing number of people are realizing that regulatory limits are not always in line with current studies, and are choosing to eliminate arsenic, lead, and chromium 6 from their drinking water, even if their city is "in compliance" with EPA regulations.   

Unlike lead, which leaches into water from pipes, arsenic comes from the source water itself, so flushing pipes or replacing plumbing will not reduce arsenic concentrations. Boiling water also does NOT remove arsenic.  Arsenic must be removed from water using a filter that is specifically designed to do so.  

Whole House Filters

Some whole house filters can be configured to remove arsenic.  We do not typically recommend these systems becasue they are very expensive, and there's no need to filter the water that is used for most household applications (e.g. flush toilet).

Point Of Use Filters

The most cost-effective way to remove arsenic, chromium 6, and other contaminants is through a point of use filter.  When shopping for these systems, we encourage you to make sure that the filter actually filters arsenic (most don't). While we believe that our advanced under sink water filtration systems have unique benefits and use filtration media that effectively remove both Arsenic(III) and Arsenic(V), some systems that use reverse osmosis can be a good choice for people who are willing to accept the downsides.  No matter what... make sure that your filter removes what you think it does!

5 Things That Most People Don't Realize About Well Water

Roughly 15 percent of Americans get their tap water from private wells, and this percentage can rise to 40% in rural states like Maine and Vermont.  It's no surprise that we receive a lot of questions from people with wells who are are concerned about water quality.   

1.  Getting A Well “Checked” Is Not The Same As Comprehensive Water Testing

There is a misconception that if someone gets their private well “checked,”  it will reveal water quality problems.  Unfortunately, that’s not the way it works.  A basic water screening has a lot of "blind spots" and gives no information about levels of lead, arsenic, chromium 6, mercury, or VOCs unless you test specifically for those chemicals.  Some states have certain testing requirements, but the scope of testing varies from state to state, and most states do not require comprehensive testing  Many banks require that certain water tests be conducted before they will issue a mortgage, but the goal of this testing is often to ensure that there are no faulty systems in the home, not to protect the health of the residents.

Bottom line:  The well's owner is responsible for having tests run.  Don't assume that the tests that were done as part of the home buying process were comprehensive.

2.  Well Water Contamination Often Comes From Natural Sources, Not Humans

Some private well owners are surprised to learn that they have contaminated water, because there are no obvious contamination sources nearby.  This is because some contaminants (like arsenic) can occur naturally groundwater at unsafe levels. 

3.  Well Water Is Often Corrosive & Can Leach Lead From Plumbing

The lead crisis in Flint put a spotlight on the fact that corrosive water can leach lead from pipes, soldered joints, and plumbing fixtures.  Unfortunately, a lot of well owners don't realize that well water can be inherently corrosive, so if a their plumbing predates 2014 (when lead-free standards were fully adopted for home plumbing components), there is potential for lead to leach into the tap water.

4.  Contaminant Concentrations (And Recognized Safe Levels) Change With Time

We cannot emphasize enough that people should get their wells tested on a regular basis, because contaminant concentrations and thresholds for “safe” water both change over time.

For example, we commonly hear homeowners in the Northeast and Southwest tell us that they tested their water for arsenic "a few years ago" and everything was fine.  They are often surprised to learn that EPA recently lowered the concentration of arsenic that is considered to be “safe."  The maximum contaminant level (MCL) used to be 50 parts per billion but was changed to 10 parts per billion a few years ago.   This means that many wells with arsenic concentrations that were considered “safe” by EPA a few years ago are now considered unsafe.

5.  Private Well Owners Are Responsible For Monitoring Their Water Quality, Not EPA

Private wells are not regulated by EPA or State Regulators, so the owners (or prospective owners) are responsible for all well water quality testing. However, figuring out which tests to do and making sense of the results can be confusing.  Some states have guidelines and recommendations, but even these can be confusing and contradictory.

Often times, prospective home owners turn to a real estate agent for advice on water quality testing, but we often hear from people who received terrible advice.  Most of the time, the mistakes are honest, but there are times when it looks like the agent was trying to facilitate a quick sale.

Ultimately, ensuring water quality of a private well is the individual responsibility of the well’s owner or prospective owner.  In support this responsibility, we encourage people to take advantage our Technical Support Team’s “Help At All Costs” policy, and lean on us to provide guidance on which lab to select in your area, which tests to run, and to help interpret the results.   This free (no obligation service) can be reached by emailing us (support@hydroviv.com) or by using the live chat function on this page.

We do not have financial agreements or arrangements with water quality test labs, and we do not “over-prescribe” testing.
