PFAS PFOS Drinking Water Testing Forever Chemicals – PFOA, PFOS, Gen X Compounds in Drinking Water
One of the most important issues related to consumer products, the environment, and the public health is the new problem “forever chemicals” and a specific group called PFAS. PFAS are man-made per- and polyfluoroalkyls chemicals that includes PFOA, PFOS, GenX, and others. Starting in the 1940s, these chemicals have been manufactured around the world and these chemicals historically can be found in food packaging, commercial household and personal products, manufacturing and industrial facilities, waste discharges, landfill leachate, and firefighting products and clothing. At this moment, the PFOA Stewardship Program has phased out SOME of these PFAS chemicals so they are no longer manufactured in the United States.
But wait, we are a global community and these compounds can bioaccumulate and can now be found in the environment and US (That is right You and me!) and the available studies suggest that these PFAS chemicals (PFOA and PFOS) can adversely impact human health. In animal studies, these chemicals have shown to cause tumors, adversely impact the liver and kidney, reproductive system, impact developmental,
The most-studied PFAS chemicals are PFOA and PFOS. Studies indicate that PFOA and PFOS can cause reproductive and developmental, liver and kidney, and immunological effects in laboratory animals. Both chemicals have caused tumors in animals. Human epidemiology studies have shown these chemicals increased cholesterol levels and the available data suggests these compound also negative influence infant birth weights, reduced immune system, thyroid hormone, ulcerative colitis, and potentially cause cancer.
The routes of exposure to this compounds includes are work environment, foodborne routes, commercial products, and our drinking water. If you work in a facility using PFAS or producing products made with PFAS you can be exposed direct exposure or contaminated air. Foodborne routes included contaminated equipment used to process food, food packaging (coated cardboard / fast food paper), cookware (use PFOA Free Cookware) and/or the environment and conditions under which the food is grown. PFAS exposure can come from consumer products like water-repellent, nonstick cookware, stain-water repellants, cosmetics, cellphones, lubricants and much more. Since these chemicals are not routinely tested in drinking water and they are difficult to breakdown, PFAS has been found in drinking water sources that include streams, lakes, groundwater, well water, springs, and even city water. “Testing by the EPA has determined that 6.5 million people have been exposure to PFOA in their drinking water and the chemical has been detected in over 94 public water supplies in 31 different states” and in 2004 99.7% of Americans had detectable levels of PFOA in their body”. The EPA advisory limit, not enforceable, for PFOA and PFOS in drinking water at 70 parts per trillion (Update).

Drinking Water Testing Kits Corrosion Lead Copper Metals – My Drinking Water is it Safe?
Article for: private well owner, spring user, city water customer, regulated water supply, water utility customer, homeowner, landlord, tenant, drinking water
The Flint water crisis reportedly started in 2014 and ended in 2019, but in reality the “crisis” started prior to 2014 and probably has not ended. Why? The problem with corrosion within the water system and individual’s homes clearly started prior to 2014 and the customers and users within the system were not aware of the short-comings in their drinking water quality, the need for corrosion control, need to replace service laterals, plumbing within their homes, the need to be proactive in protecting your personal and families’ health, lack of public outreach and education, and not knowing the wrong signs of a corrosion problem The main purpose of this article is to help identify the warning signs of a potential corrosion problem with your drinking water. The signs of a corrosion problem come in many forms, but it is important for the user to take responsibility for keeping their eyes open. Corrosion of our drinking water supplies is a very common water quality and public health issue that is related to not only the raw water quality, level of pretreatment, status of the community distribution system, the internal plumbing for a building, the usage and management of water within the building, and the fixtures used within the system. This sounds overwhelming, but there are clear warning signs you may have a problems.
The most common signs of a problem with corrosion included the following:
- Blue-green or greenish water or even reddish brown or brown water that may be intermittent and worse in the hot water than the cold water.
- Staining of porcelain fixtures, such as sinks, drains, or tubs that appear green, blue-green, and reddish brown.
- Coatings on aeration devices that appears greenish-gray or bluish green and particles on the screen of the aerator that appear green, bluish-green, greenish-gray, reddish-brown, yellow-brown, or even bluish-gray.
- Discoloration of water piping near solder joints and/or pin-hole leaks in piping and the premature failure of water appliances and water heaters.
- Old piping in a home that may include lead pipes or piping that was installed using high lead solder, such as lead service lines and galvanized piping.
- The first flush of the water from the tap may have a bitter taste.
What is the age of your home, when was the house last remodeled, and the piping in your home?
YOUR household plumbing may be the cause for lead in your drinking water. In older homes, lead was used to make the piping and/or solder. In homes, built prior to 1930’s water pipes were primarily made from lead. These pipes can be identified because the piping tends to have a dull gray color, can be scratched with a key, and a magnet will not stick to the piping. In buildings built between the 1930’s and early 1980’s, copper pipes were often used, but the solder contained elevated levels of lead. The primary source of the lead includes the use of lead pipes, lead lined tanks, and use of 50/50 lead/tin solder. Because of the concern with lead, the EPA banned the use of high lead solders in 1986.
In the 1950’s and 1960’s galvanized water lines was utilized in new home construction. Currently, this type of piping is not widely used, but it is more commonly used with well water applications. This piping is steel piping that has a zinc coating to reduce the tendency for the piping to corrode. When this pipe corrodes, the pipe rust from the inside of the pipe and then works outward. When this occurs, the water may produce intermittent discolored water that tends to be brown, yellow, or reddish brown, and the piping will likely clog with rust and most likely collapse over time. This does not mean that a newer home is safe from lead contamination; in fact, the available data suggests that buildings less than 5 years old can have high levels of lead.
In fact, buildings built prior to 1986 likely contain some lead plumbing. Prior to 2014, the legal definition for “lead free” was plumbing fixtures with a lead content of less than 8 %. In 2014, the term was redefined to include only fixtures with a lead content of 0.25% and newly installed fixtures must use the “lead free” materials, but this did not apply to fixtures currently in use.
What You Can Do to Protect Yourself and Your Family?
After getting this information, you should do the following:
- Inspect your plumbing system for signs or evidence of a corrosion problem and low cost lead screening testing (water) or (paint,dust, soil).
- Take note of the visual and aesthetic signs of a corrosive water problem.
- Try our Free Drinking Water Diagnostic Tool.
- Order the Drinking Water Guide.
- Get Your Drinking Water Tested and the Results Reviewed by a Professional. At a minimum, we recommend the “Corrosion Check” Water Test Kit.
- Act to improve your drinking water quality by reporting problems to your local water authority for public water supplies or if your water comes from a private water source take the necessary action to reduce the risk to the health of yourself and your family and to reduce the potential costs associated with the premature failure and/or invalidating the warranty of water related appliances, water leaks and associated damage, and/or the additional operational costs associated with inefficiencies associated with clogged or corroded piping/equipment.
- Update fixtures and piping and consider the use of point-of-use filters or a whole-house water treatment system. Before installing a water treatment system, please get a comprehensive water quality test (City Water) or (Well Water).

PFOS in Water – Is there are formal drinking water standard?
Source: New Hamphire Public Radio – 11/5/2018
“Right now, state regulators are doing something they’ve never done before: writing their own limit on a chemical contaminant in drinking water.
It’s called a maximum contaminant level, or MCL. In the past, like most states, New Hampshire has used federal standards as its default MCLs.
Now, the legislature has told the Department of Environmental Services for the first time to write its own MCL, from scratch.
It’ll require public water systems to routinely test and treat drinking water for four types of likely toxic PFAS chemicals – known as PFOA, PFOS, PFHxS and PFNA.
The MCLs will also become the state’s new ambient groundwater quality standard for the chemicals, meaning if cleanup will be required if they’re found in groundwater at a higher level.
Right now, the state uses the federal government’s advice of 70 parts per trillion as its groundwater cleanup standard. The state has no formal MCL for PFAS in drinking water.
The new MCL is expected to be more stringent than that EPA guidance, and will require costly new testing and treatment protocols for drinking water systems around the state.
PFAS, or per- and polyfluoroalkyl substances, were once common in a range of industrial and household products. They have been linked to serious health problems and have contaminated water supplies across the state and country……..”

This Year- Asked About Reverse Osmosis Treatment System
For some reason, this year we received a lot of questions from individuals looking to purchase or install a reverse osmosis treatment system. The first question they all ask was about the features, models, and other details, but none answer the question why? What was the problem or purpose? They assumed they needed this system.
So my questions went as follows:
Question 1: Why? What is the Problem – their answer in all cases was they thought it would be better.
Answer 1: They all thought they needed to install a reverse osmosis unit on their drinking water to protect their family. They did not identify a problem such as salty water, metallic taste, etc. When this happens, my first assumption is something went wrong somewhere or there is a new water treatment ad on TV pushing citizens to drink “Pure Water”, i.e., H20 or dihydrogen monoxide, only. First – Drinking absolutely pure water for the long-term is not wise.
Question 2: Where does your water originate? Well water, City or Public water, or shared spring.
Answer 2: 80% said city or public water, 10 % said private well, and 10% said a local spring.
For the city and public water users, I said it was unlikely you needed a reverse osmosis unit because your source is regulated and must meet the state and federal drinking water standards, but after Flint and other cases this may not be true 100 % of the time. I ask them if they look at the Consumer Confidence Report for their system and they had no idea what I was describing. I pointed them in the direction of the EPA Consumer Confidence Report (NOTE: If there is no report online, you will need to call your water supplier) and in every instance the water source was meeting drinking water standards, but they had some occasional problems with trihalomethanes, i.e., chlorine by-products, bacteria, and a few with copper, arsenic, fluoride, and lead or corrosion issues. For these individuals, I recommended the following:
a. Get a Comprehensive City Water Information Analysis
b. Based on the initial information and assuming the primary issue was trihalomethanes and chlorine by-products, the primary need most individuals was an under the counter “Point-of-Use” Carbon Filtration System for the Sink, Refrigerator, and/or Shower and in some cases for older homes I suggested a first flush test for lead and copper and then have a plumbing contractor inspect the service lines and plumbing in the home. In one case, the homeowner found a slimy bacterial growth in the toilet tank reservoir, so we suggested they flush the system and suggested the installation of a water filter canister so they could flush and shock disinfect the water lines in the home. For a small office, I might suggest a water cooler model. I do not recommend a Whole House Reverse Osmosis unit.
c. Reverse Osmosis Treatment was not needed in ALL cases.
For the well water users (POE Systems- UV disinfection), I asked them when was the last time they tested their water and if the water had any aesthetic problems. One complained of a salty taste, one was just concerned because of health issues, and the rest reported aesthetic problems ranging from odors to discoloration to staining. If they did not have a recent water test, we recommended the appropriate water testing based on their description of the problem and surrounding land-use activities.
Homeowners that reported – Salty Water Taste and not near a gasoline station or farming area we recommended a basic water quality test with bacteria.
Homeowners that reported discoloration that was red, black, green, and/or a metallic taste we recommended a basic water quality test.
Homeowners that reported a chemical odor or metallic sheen and located in an area surrounded by agricultural activities or petrochemicals we recommended a test that included bacteria, metals, Volatile Organics, herbicides, and pesticides. If they reported slimy coatings or films, we added a nuisance bacteria test.
We also directed a few of these users to our Phone App and Diagnose It for a self Diagnose.
At this point, NOT one of these individuals has installed a reverse osmosis unit, but it looks like the guy with the salty water may need a system. We did find out that about 90% of the well owners needed to shock disinfect their well, 50% needed to install a UV disinfection System, 30% had a corrosion related problem, and 20% had to treat the water for an iron, manganese, or sulfur problem.
For the “Spring User” – we recommend the water be tested for total coliform and E. coli. and general water quality. If the samples come back positive and there was a concern iron and manganese content we recommended a water test that included bacteria (including standard plate count and nuisance bacteria, iron, manganese, and total dissolved solids). Some of the users complained about getting diarrhea, so we recommend the equivalent of a Pathogenic Screen Test for Your Drinking Water.
Guess What ! – the diarrhea case was positive for 1 pathogenic organism. Our recommendation was to not use that spring and if possible have the spring properly abandon. If you want to use a local spring source, plan on boiling the water at a minimum and use a water pitcher filter (test regularly at least quarterly).
For the guy that needed a reverse osmosis system, he also needed a pretreatment system to deal with the bacteria, hardness, and prepare the water for the R/O unit. For individuals on city water that want a point of use R/O, we have found that is is typically necessary to prefilter the water to remove particles, add a carbon unit to remove chlorine, and is some cases reduce the hardness of the water. Please keep in mind both applications are for Point-of-Use and not – Wholehouse RO treatment.
Looking for a Reverse Osmosis Unit – Questions?
- How much water do I need per day?
- Does my water require pretreatment? If you do not have recent water testing data, we recommend this comprehensive assessment (Complete RO screen). Testing for silica is critical.
- How much water will be “wasted” per day and where will this water go? Some R/O units process 2 to 4 units of water to make 1 unit. Therefore, you may waste 1 to 3 gallons of water to make 1 gallon.
- Do I need to install a booster pump- Do I have the proper pressure in my system?
- Do you need to re-mineralize the water for taste or to increase the pH?
Interesting R/O Unit with Booster Pump
Finally -You may want to be looking for an NSF/ANSI 58 approved systems – You can try this product search. “NSF/ANSI 58 establishes the minimum requirements for the certification of point-of-use (POU) reverse osmosis systems designed to reduce contaminants that may be present in public or private drinking water. The scope of NSF/ANSI 58 includes material safety, structural integrity, total dissolved solids (TDS) reduction and other optional contaminant reduction claims. The most common optional claims addressed by NSF/ANSI 58 include cyst reduction, hexavalent and trivalent chromium reduction, arsenic reduction, nitrate/nitrite reduction, and cadmium and lead reduction.” and you most likely want to hire a local trained professional to assist with product selection and install.

Water Treatment – “The Salt Free Water Softener”
The Keystone Clean Water Team is a 501c3 and the main goal of the organization is to educate and inform the public on issues related to watershed management, water quality, groundwater, conservation, and the links between the environment, economy, and living within a community. As a group, we provide educational outreach via are webportals, workshops, and other training programs. During the past year, one of the most common questions we get ask is: “What do you think of the “Salt Free Water Softener”, my normal answer is “It depends”.
For some “salt free water treatment” systems by most common answer is quackery. I will not mention these systems, but I will refer you to a great website so we do not have to worry about liability (H20.com). Of the softener and “salt-free” systems we have been able to seen the field the ones that appear interesting would include the following:
Water Softener (Conventional and With A Twist)
In general water softeners reduce the level of total hardness in the water and when this hardness is removed it is replaced with ions of sodium or potassium. The total hardness can include elements like calcium, magnesium, iron, manganese, and other divalent/or mulivalent cations, i.e., ions that have a positive charge of more than one. These ions are replaced by ions with a positive charge of one. The system requires an internal resign that acts as the treatment area and a brine tank that is used to backwash and recharge the resin. These have a long-history of use, but can increase the level of sodium and potassium in the water. These systems can be vulnerable to bacterial regrowth, chlorine interaction, and in some cases “Iron Out” needs to be added to the brine tank. A water softener can add in dealing with issues related to more significant scale formation and problems with iron and manganese. If you are considering this treatment system, we recommend that you conduct a comprehensive water quality test and seek the advice of a local expert. If you are a DIY, get your water tested and please visit this portal (Whole House Water Softener / Alternative No-salt Softener (just reduces hardness- Using a Crystal Eagle Anti-scale media ) ). For the record, we have seen problems when a water softener is added to an older home and system. In these cases, we have seen that water softener was typically removing too much of the water hardness. When this softened water was introduced to the system, the system experience elevated levels of lead, copper, and other trace metals and because the line was not properly shock disinfected intermittent water quality problems with “dirty and discolored water” (PS: this is Flint Michigan in a nutshell).
Aquios Systems (Aquios FS-220) (Salt Free)
The Aquios technology uses a polyphosphate/silicate additive in the media to bind or sequester the hardness as a mineral form. The media is known as Siliphos Data Sheet. Rather than feeding a polyphosphate chemical into the water like is done for corrosion control and sequestering for some municipal water sources, this is accomplished using a point of entry or use treatment system. The filter has a fixed capacity for hardness reduction, so it is critical to get a detailed water quality test so the system can be properly sized. In addition, the system normally included prefiltration to reduce or remove sediment and chlorine.
This systems uses a chelatin approach to reducing the total hardness of the water. Therefore, the hardness is bound and sequestered within the media, which is very similar to the Aquios approach, but they use CitraCharge. CitraCharge appears to be an additive that includes citric acid, which is a weak organic acid. From the companies website, “The chelant in CitraCharge creates a ring structure to bind the ions to the CitraCharge instead of to other ions, which is what typically causes scale and hard-water deposits.”

What is in your well water?
If your water comes from a private well, you know that the safety of your drinking water is up to you. At the federal level and in most states there are no regulations that govern private wells, but the CDC and EPA does recommend that you test your well water at least once a year. You may want to check the quality of your water more often if there are known problems with wells in your area or if you have experienced any flooding or land disturbances near your well. Indications of a change in water quality include cloudiness, odor, and unusual taste.
You can quickly and easily test your well water for a variety of contaminants with Groundwater City Water Well Water Testing Kit (Safe Home). This kit is a great screening test to help you determine the quality of your water.
A DYI Well Water single kit includes all of the following water tests:
- Chlorine (Just in case the well was shock disinfected)
- Copper
- Lead
- Nitrates & Nitrites
- Iron
- Alkalinity
- pH
- Hardness
- Bacteria
These easy to use tests will give you results within 10 minutes, with the exception of the bacteria test which takes 48 hours for full results. There’s no need for expensive equipment or to mail samples to a lab. Each test is calibrated to the EPA standards. Once you have your results, compare them to the EPA recommendations and guidelines for water quality limits.
If you would rather a more detailed chemical analysis of your Well Water or City Water. We would recommend the specially designed water testing kits for people on well water, the Well Water Testing Kit includes over 70 water quality tests for a complete water analysis or City Water (over 80 parameters) . You’ll be able to identify the presence of chemicals, metals, and even bacteria like E. coli.

Pennsylvania Lead Task Force – John Yudichak. Senate Resolution 33
Senate Approves Resolution Creating Task Force to Investigate Threat of Lead Exposure in Pennsylvania
Senator John T. Yudichak recently announced that Senate Resolution 33 — which creates a bipartisan task force to investigate the scope of Pennsylvania’s lead exposure problem — was approved unanimously by the full Senate. The resolution had been approved unanimously by the Environmental Resources and Energy Committee at the end of April.
Senator Yudichak introduced the resolution earlier this session because lead exposure can threaten the health and well-being of every Pennsylvanian—especially senior citizens and children. “The task force report will advance cooperative efforts to arm the General Assembly with better information and best practice recommendations to develop new lead abatement programs that more aggressively mitigate lead exposure in Pennsylvania,” said State Senator John Yudichak.
[amazon_link asins=’B00IJG4X50′ template=’ProductAd’ store=’webdespro-20′ marketplace=’US’ link_id=’24f7140f-b2bb-11e7-a067-bbd7473f7890′]
The resolution calls for the Senate to establish a task force on lead exposure comprised of the chairs of the Environmental Resources and Energy Committee and the Health and Human Services Committee and two members appointed by the Senate President pro tempore and the Minority Leader. An advisory committee of the Joint State Government Commission will conduct a comprehensive review of Pennsylvania law and public policy related to lead exposure and abatement practices and then submit a report to the task force and full Senate within 18-months. The report must assess the age of housing and infrastructure, lead exposure threats, and identify the prevalence of lead in structures where children spend significant time.
A few key points
- This is not just a drinking water issue. Lead is present in many homes and sources include old lead paint, cookware, make-up, and other consumer products.
- If on city water, check piping in home for lead pipe and evidence of corrosion. Remove the aeration devices and clean and flush the water lines to remove any films and coatings.
- If on city water – read the Consumer Confident Reports generated by water supplier and look for signs of corrosion.
- If on well water – get your water tested.

Radon occurrence in groundwater from 16 geologic units in Pennsylvania
Evaluation of radon occurrence in groundwater from 16 geologic units in Pennsylvania, 1986–2015, with application to potential radon exposure from groundwater and indoor air
Scientific Investigations Report 2017-5018
“Results from 1,041 groundwater samples collected during 1986‒2015 from 16 geologic units in Pennsylvania, associated with 25 or more groundwater samples with concentrations of radon-222, were evaluated in an effort to identify variations in radon-222 activities or concentrations and to classify potential radon-222 exposure from groundwater and indoor air. Radon-222 is hereafter referred to as “radon.” Radon concentrations in groundwater greater than or equal to the proposed U.S. Environmental Protection Agency (EPA) maximum contaminant level (MCL) for public-water supply systems of 300 picocuries per liter (pCi/L) were present in about 87 percent of the water samples, whereas concentrations greater than or equal to the proposed alternative MCL (AMCL) for public water-supply systems of 4,000 pCi/L were present in 14 percent. The highest radon concentrations were measured in groundwater from the schists, gneisses, and quartzites of the Piedmont Physiographic Province.
[amazon_link asins=’B00H2VOSP8′ template=’ProductAd’ store=’webdespro-20′ marketplace=’US’ link_id=’7f5cf695-bd0e-11e7-8683-83a2417f4713′]
In this study, conducted by the U.S. Geological Survey in cooperation with the Pennsylvania Department of Health and the Pennsylvania Department of Environmental Protection, groundwater samples were aggregated among 16 geologic units in Pennsylvania to identify units with high median radon concentrations in groundwater. Graphical plots and statistical tests were used to determine variations in radon concentrations in groundwater and indoor air. Median radon concentrations in groundwater samples and median radon concentrations in indoor air samples within the 16 geologic units were classified according to proposed and recommended regulatory limits to explore potential radon exposure from groundwater and indoor air. All of the geologic units, except for the Allegheny (Pa) and Glenshaw (Pcg) Formations in the Appalachian Plateaus Physiographic Province, had median radon concentrations greater than the proposed EPA MCL of 300 pCi/L, and the Peters Creek Schist (Xpc), which is in the Piedmont Physiographic Province, had a median radon concentration greater than the EPA proposed AMCL of 4,000 pCi/L. Median concentrations of radon in groundwater and indoor air were determined to differ significantly among the geologic units (Kruskal-Wallis test, significance probability, p<0.001), and Tukey’s test indicated that radon concentrations in groundwater and indoor air in the Peters Creek Schist (Xpc) were significantly higher than those in the other units. Also, the Peters Creek Schist (Xpc) was determined to be the area with highest potential of radon exposure from groundwater and indoor air and one of two units with the highest percentage of population assumed to be using domestic self-supplied water (81 percent), which puts the population at greater potential of exposure to radon from groundwater.
Potential radon exposure determined from classification of geologic units by median radon concentrations in groundwater and indoor air according to proposed and recommended regulatory limits is useful for drawing general conclusions about the presence, variation, and potential radon exposure in specific geologic units, but the associated data and maps have limitations. The aggregated indoor air radon data have spatial accuracy limitations owing to imprecision of geo-coded test locations. In addition, the associated data describing geologic units and the public water supplier’s service areas have spatial and interpretation accuracy limitations. As a result, data and maps associated with this report are not recommended for use in predicting individual concentrations at specific sites nor for use as a decision-making tool for property owners to decide whether to test for radon concentrations at specific locations. Instead, the data and maps are meant to promote awareness regarding potential radon exposure in Pennsylvania and to point out data gaps that exist throughout the State.”
