The Healthy Homes, Healthy Communities, and Healthy Drinking Water Initiatives or Programs
The Healthy Homes Program / Healthy Home Initiates
“Environmental hazards in the home potentially harm millions of children each year. The Healthy Homes Program addresses multiple childhood diseases, exposures, and injuries that may originate in the home. The Initiative has a focus on housing-related hazards and educating and informing the public. This was one of the key factors missing in the Flint Michigan Drinking Water Crisis. In response to Congress, the US Department of Housing and Urban Development (HUD) launched its Healthy Homes Initiative (HHI) in 1999. The objective of the program was to protect children and their families from housing-related health and safety hazards.
HUD has developed a new Healthy Homes Strategic plan that lays out the next steps their office will take to advance the healthy homes agenda nationwide. The HHI builds upon HUD’s successful Lead Hazard Control programs to expand its efforts to address a variety of environmental health and safety concerns including: mold , lead , allergens/ asthma, air quality gases and VOCs , pesticides , and radon .”
The Center for Disease Control (CDC) developed the Healthy Communities Program (HCP). The program uses local, state, territory, and national partnerships to attempt to prevent chronic diseases and reduce health disparities (Note: For me this is a buzz word related to equity, we will never have equal outcomes in communities because of genetics, individual choice, and economics, and lifestyle issues, but we can attempt to treat all individuals equally).
Nearly 50% Americans die of one chronic disease, such as: heart disease, stroke, diabetes, cancer (polycythemica vera/ radon), obesity, and arthritis.
Chronic diseases make up 7 of the 10 leading causes of death in the United States and based on our recent experience with COVID, these diseases made individuals more vulnerable to the negative and adverse impacts associated with COVID-19. Not only can these diseases result in death, they can also be associated with chronic pain, inability to function and support an individual or family, limit daily activities, and significant impact a family’s budget and health care costs.
The Healthy Communities Program attempts to raise awareness and provide fact-based information, but also encourage citizens to make better choices, increase physical activity, make better food choices, and reduce the use of tobacco. These efforts addressed key factors that raise the risk of disease, including: CDC funded 331 communities and 52 state and territorial health departments through HCP .
Drinking water comes from a variety of sources including public water systems , private wells , or bottled water. Ensuring safe and healthy drinking water may be as simple as turning on the tap from an EPA-regulated public water system. Other water sources may need to have point-of-use or whole house filtration systems, citizens educated and informed, water quality monitored, water distribution systems flushed and septic systems need to be serviced or inspected. It is important to know where drinking water comes from, how it’s been treated, and if it’s safe to drink. Therefore, it is important to Know Your H20 and Get on the Path to Clean Water.
WASHINGTON – Today, the U.S. Environmental Protection Agency (EPA) published the Final Fifth Drinking Water Contaminant Candidate List (CCL 5), which will serve as the basis for EPA’s regulatory considerations over the next five-year cycle under the Safe Drinking Water Act. This update includes a substantial expansion of per- and polyfluoroalkyl substances (PFAS), an important first step towards identifying additional PFAS that may require regulation under the Safe Drinking Water Act.
“Following public engagement and robust scientific review, the final contaminant candidate list is the latest milestone in our regulatory efforts to ensure safe, clean drinking water for all communities,” said EPA Assistant Administrator for Water Radhika Fox. “As EPA takes action to protect public health and the environment from PFAS, including proposing the first nationwide drinking water standards later this year, today’s final CCL 5 looks further forward to consider additional protective steps for these forever chemicals.”
A year ago, EPA published the PFAS Strategic Roadmap, outlining an Agency-wide approach to addressing PFAS in the environment. Today’s announcement strengthens EPA’s commitment to protect public health from impacts of PFAS and support the Agency’s decision-making for potential future regulations of PFAS.
In developing the Final CCL 5, EPA requested public nominations, providing an opportunity for people to make recommendations to the Agency about specific contaminants of concern that may disproportionally affect their local community. EPA further enhanced the CCL process based on comments received on this CCL and previous CCLs, including by prioritizing data most relevant to drinking water exposure, improving considerations of sensitive populations including children, and considering the recommendations included in the Review of the EPA’s Draft Fifth Contaminant Candidate List (CCL 5) report from the Science Advisory Board. These improvements resulted in a Final CCL 5 that can better inform prioritization of contaminants for potential regulatory actions and/or research efforts.
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 drinkingwater at 70 parts per trillion (Update).
The Keystone Clean Water Teams goal is to provide resources to help you get your water tested and to provide fact based information. Since this testing is normally not readily available, we have partnered with a national testing company to provide you with some testing options. We are offering these 4 informational testing packages.

Article by Pike County Conservation District: By Rachel Posavetz, Watershed Specialist.
“Riparian buffer is the term for an area of vegetation that grows along a waterway to help prevent substances from reaching the water. The fact that this type of area has its own term should be telling of its importance. As water flows across the land, or the watershed region, it carries with it a whole slew of pollutants: sediment, chemicals, nutrients, bacteria, litter, etc. These pollutants are filtered and absorbed by the plants and soils growing in riparian buffers, and therefore prevented from entering the water.
Riparian buffers provide flood water storage and help to prevent soil erosion during high rain events and along high motion waters such as streams and lake shores. They also provide cooling shade which helps heat-sensitive aquatic organisms survive (such as brook trout), and control algal growth by blocking sunlight.
Where do we need riparian buffers? Every stream, lake, wetland, and pond will benefit from these helper plants filtering out harmful substances, holding in the soil, and allowing excess water to infiltrate into the ground water system. These plants are most crucial along the waterway edge, and the greater the riparian buffer width, the better.
What makes a good riparian plant? Almost anything with roots, and preferably native species that are tolerant to wet conditions. Trees and shrubs, grasses and forbs (wildflowers), and sedges and rushes, have strong root systems that lock in the soil and are adapted for surviving in our seasonal weather changes. Trees are the most beneficial because they establish long-term roots, continue to grow over time, and provide the most shade, food and shelter proportional to the space they occupy. A healthy riparian buffer mimics the natural the habitat for the area in which it is located, whether it be a forest or a meadow, with a diversity of plant types and heights. Sod, or mowed grass, has leaves too short to aid in filtering, and roots too shallow to aid in erosion protection.
What else do they do? Riparian buffers add to the available habitat and food sources for wildlife such as birds, pollinators, mammals, and other critters, including aquatic ones. Did you know “trees feed trout”? The aquatic insects at the bottom of the food chain, like caddisflies, munch on the tree leaves and their biofilm (algae and bacteria) that have fallen into the streams. Trunks and branches that fall into the stream create aquatic habitat variety as well.
Who can make a riparian buffer? You can! If your property borders a waterway, you can enjoy designing a grow zone that suits your liking. Though it will require some maintenance until the new plants establish, you can enjoy the beauty of the flowers right away. Check the links below to learn more.
Lastly, riparian buffers can serve as a reminder to us that water levels fluctuate within the floodplain, and we should keep development a safe distance from the water’s edge.” (Article link)
Our thoughts on riparian buffer zones:
1. Overall we agree, we should protect and restrict encroachment on stream channel, floodway, floodplain, wetland, and hydric soil boundary.
2. This should not be a one-size fits all “safe distance”, but based on site-specific information and conditions.
3. Most beneficial chemical reactions happen at this critical transition zone – if you want to protect streams from nitrogen impact from nitrate – maintain the anoxic zone and transition zones between uplands and streams.

“Tests reveal bottled water contains nearly twice as many microplastic particles per liter as tap water. The contamination is thought to originate from the manufacturing process of the bottles and caps
Researchers tested 259 bottles of 11 popular bottled water brands for the presence of microscopic plastic. On average, the bottled water tested contained 325 pieces of microplastic per liter
Only 17 of 259 bottles were found to be free of microplastic particles (5 mm and 0.003 mm), and none of the brands tested consistently free of plastic contaminants. The worst offender was Nestlé Pure Life, the most contaminated sample of which contained 10,390 particles per liter
In response to these findings, the World Health Organization has vowed to launch a safety review to assess the potential short- and long-term health risks of consuming microplastic in water
A report by the U.K. Government Office for Science warns plastic debris littering the world’s oceans — 70 percent of which does not biodegrade — is likely to triple by 2025 unless radical steps are taken to curb pollution.”
NSF Intl. has developed a test method and protocol to verify a water treatment device’s ability to reduce perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) to below the health advisory levels set by the U.S. Environmental Protection Agency (EPA).

“In 1654, Rembrandt painted a woman, in Amsterdam, bathing in a stream. As she lifts her nightdress above her knees and treads deeper, the woman is stepping from one world into another. Among art historians, the transition she is making is metaphorical. But to a biologist, it is also ecological.
We imagine water to be clean, and we imagine clean to mean lifeless, and yet all the water you have ever bathed in, swum through, or drunk has been full of life, from bacteria to tiny crustaceans. So, too, the pipes in which it travels. As water passes through pipes in general and showerheads in particular, a thick biofilm builds up. Biofilm is a fancy word that scientists use to avoid saying “gunk.” It is made by individuals of one or more species of bacteria working together to protect themselves from hostile conditions—including the flow of water, which constantly threatens to wash them away—via their own excretions.”
This is a very timely article – we work with a lot of private water systems, public water supply systems, and businesses that have a biofilm problem and to be honest I have had this problem in my home (s) that were serviced by both city water and well water.
First Step – Learn
Biofilms and Bacteria – bacteria does not normally grow free-living in the drinking water, but attached to the piping or surfaces within the system as a biofilm. This microbiological community can include a variety of organism that may be aerobic (like or need oxygen), anaerobic (low oxygen), or facultative(in the middle). The bacterial coating may be clear or discolored, create odors, contain trace metals, or promote microbiologically induced corrosion. The bacteria can impact the quality of the drinking water and the integrity of the distribution system. When people test city or well water, they normally only test for total coliform bacteria and may be E. coli., but that is not enough.
Second – Diagnose
The next step is to diagnose, but diagnose is really using a combination of observations and testing to determine if there may be a problem or concer.
We recommend the following:
Visually inspect the plumbing – look in the back of the toilet tank is the wall discolored, if discolored does it feel slimy, look in the bathroom do you see films or coating on showerheads or other surfaces. If you have any clear tubing, does the tubing have any observable films or coatings. If you have a particle filter, does it feel slimy.
Are there any odors or strange smells to the water.
If the water sits, does it have a floating metallic sheen on the surface.
Have you been experiencing problems with discolored water that is black, brown, or even greenish blue?
Flush the water heating tank – what do you see?
If you observe a film or coating, you may have a biofilm problem.
If the bacteria is pink, this may be Serratia marcescens. This is typically an airborne bacteria and we suggest that you wash the services with an anti-microbiological cleaner, monitor and control the humidity of the room, regularly clean the surfaces, wipe down showers after use, and keep the ventilation fan running for at least 20 minutes.
The next question is do you have any health issues?
If health issues are gastrointestinal and you have slime coatings – We recommend testing for total coliform, E. coli., and slime forming bacteria, and standard plate count.
If you do not have health issues, but have slime coatings with discolored water, we would recommend total coliform, iron related bacteria, slime forming bacteria, and standard plate count.
If you major health issues that include respiratory issues with or without gastrointestinal issues we recommend total coliform, E. Coli, and Waterborne Pathogen Panel.
Third Step – Test/ Monitor
Testing can include a variety of measures that include:
NSF/ANSI 401 addresses the ability of a water treatment device to remove up to 15 individual contaminants (listed below), which have been identified in published studies as occurring in drinking water. While not a public health issue, the contaminants covered in NSF/ANSI 401 have been detected in drinking water supplies at trace levels and can affect some consumers’ perception of drinking water quality. (NSF/ANSI 401 also applies to reverse osmosis (RO) water treatment.)
DEET (N,N-Diethyl-meta-toluamide): a pesticide and common active ingredient in insect repellents.
401: an organic compound that is widely used as an herbicide.
Linuron: an herbicide often used in the control of grasses and weeds.
Chemical Compounds
TCEP (Tris(2-chloroethyl)phosphate): a chemical compound used as a flame retardant, plasticizer and viscosity regulator in various types of polymers including polyurethanes, polyester resins and polyacrylates.
TCPP (Tris(1-chloro-2-propyl) phosphate): a chemical compound used as a flame retardant.
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:
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 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.
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?
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. If your looking for a treatment system to remove Pfas/Pfos (meets NSF P473)
Lycoming County, Pennsylvania – Flooding Private Water Wells – contaminated drinking water
With the significant and long-term rainfall events, we have rural areas that have undergone flooding. If your area has been flooded and you use private water wells, you must take some action to ensure that your water well is thoroughly cleaned and sanitized. When water wells become inundated or a region floods, it is possible that the contaminated water may enter the water well directly via the well cap or indirectly through natural macropores (i.e., spaces between the rock or particles of sand and gravel, in the unconsolidated material or bedrock. OUR suggestions are as follows:
If you are handy and have power, we recommend that you inspect the area around the well and remove the well cap and shock disinfect the well.
We would recommend the well be purged to waste – do not purge the water into the septic system or back directly into the well initially. When the well water appears clear, recirculate the water back into the well to wash down the sides of the casing. Please make sure to by-pass any water treatment devices and water filters and do not run this water through your main plumbing of the home.
We then recommend that the well and main line be shock disinfected twice. This is our website that contains information on how to shock disinfect a well and a link to a video that reviews the process and to the preferred chemical to use (Link to Amazon). Please note- Some local well drillers has this chemical available. If you can not get this chemical, it is ok in an emergency to use household bleach that does NOT contains scents, fragrances, or other additives.
After the well has been shock disinfected and purged one to waste, the second shock disinfection should be to the well and the distribution system of the home. When you conduct this disinfection, it is critical that you remove all aeration devices, by-pass all filters, and remove any hoses or connections that have inline filters or screens, i.e., your washer hoses and you may want to consider raising the casing, adding a sanitary well cap, and adding a Well Seal.
When you believe you have shock disinfected the well properly, we recommend the following:
Screen the raw untreated well water and the water from the piping of your home using a DIY Informational Water Testing Screening Test. (Link to TA – portion of the proceeds benefits the Keystone Clean Water Team)
If the screening test is negative, we would suggest that you then contact a certified laboratory PA by county and have the water tested for at least total coliform and E. coli. using a method that gives you a physical count, i.e., an enumeration method.
If the water is still positive for total coliform and/or E. coli, we would recommend that you shock disinfect the well and distribution system a second time, but use a longer reaction time and then retest using a certified laboratory.
If you are in an area with farming or petrochemical storage or high use, we would also recommend an informational water screening test that includes trace metals, herbicides, pesticides, and volatile organic compounds (Link to NTL – portion of the proceeds benefits the Keystone Clean Water Team).
PS: Adding too much disinfection chemical to the well is not wise, this can cause the release of arsenic and other trace metals into the water.
