Healthy Drinking Water and Healthy Homes – Communicating to the Public
What is a Drinking Water Advisory?
DO NOT PANIC ! What are Drinking Water Advisories and What Should You Do ?
Drinking water advisories let customers know that their tap water or drinking water could be contaminated and make them sick. There are no advisories for private well owners or drinking wate systems that are NOT regulated. Advisories are used to send a message to users, customers, individuals, business, schools and other institutions that there is a potential problem with the water and how to act without getting into the details that are part of a Community Water Supply System or a regulated Non-Community System like a school, gasoline station that serves food, etc. One thing we learned from Flint, Michigan and other case studies is that the citizens and most users do not really know what a “Drinking Water Advisory Means” and most Authorities or Water Companies DO NOT Know How to Explain the Situation.
The drinking water advisories typically fall into one of these 3 categories: “Boil Water Advisory”, “Do Not Drink Advisory”, and “Do Not Use Advisory”. Just to confuse you a little more, there is also something called a Health Advisories that are published by EPA and we will deal with these separately.
Boil Water Advisory
If your local health officials, water company, water provider, or Authority issues a boil water advisory, you should take the immediate action of not using your drinking water for consumption (DO NOT DRINK !).
The boil water advisory means that the water may or does contain a pathogen, i.e., a disease-causing agent. The primary actions would include establishing another temporary water source, such as bottled or bulk water, or boiling the water prior to use and consumption. (Please Note: I did not say filter the water or Microwave the water and I did not say drink hot water. I said BOIL!)
Boil water advisories the details.
- Use bottled water, bulk drinking water, or boiled water for drinking, and to prepare and cooking food, feeding the pets, brushing your teeth, and making baby formula.
- If bottled water is not available, bring your tap water to a full rolling boil for 1 minute for elevations below 6,500 feet and if you live at an elevation of over 6,500 feet a 3 minute rolling boil is needed. After boiling, allow the water to cool before use and while it is cooling give a good shake to try and “re-aerate” the water, it will taste better.
- If a boil water advisory is issued, you CAN NOT just filter your water through a particle filter or install or use a Class B UV water treatment system– this is NOT adequate. The verb in the sentence is “BOIL” not filter, but it is ok to boil and then filter (YES). They make some very good home water coolers
- Do not use ICE comes from your automatic ice maker even if the unit has a filter or inline UV unit, the water must be cooled and then cooled and then you can make ice.
- Breastfeeding is the better choice. If you formula feed your child, provide ready-to-use formula, if possible, or the water must be boiled (not Microwaved or heated) and cooled. The boiled water should be used within 72 hours (Source: Allinahealth.org)
- You a water screening test on your temporary water source and your water source when it comes off the boil water advisory.
Handwashing – (After COVID you should be a PRO)
- In many cases, you can use tap water and soap to wash hands during a boil water advisory. DO NOT wash your hands in boiling water or hot water. Follow the guidance from your local public health officials.
- Be sure to scrub your hands with soap and water for at least 20 seconds. Then, rinse them well under running water, but make sure to dry your hands.
- If soap and water are not available, use an alcohol-based hand sanitizer that contains at least 60% alcohol (Source: CDC).
Bathing and showering
- Be careful not to swallow any water when bathing or showering.
- Use caution when bathing babies and young children. Consider giving them a sponge bath to reduce the chance of them swallowing water. You do not need to use bottled water, but you can if you wish.
Brushing teeth
- Brush teeth with boiled water that has cooled or bottled water. Do not use tap water that you have not boiled. You may want to then store your toothbrush in some saline or salt water to prevent bacterial regrowth.
Washing dishes
- If possible, use disposable plates, cups, and utensils during a boil water advisory.
- Household dishwashers generally are safe to use if:
- The water reaches a final rinse temperature of at least 150 degrees Fahrenheit (66°Celsius), or
- The dishwater has a sanitizing cycle.
- At the end of the boil water advisory, we recommend running a sanitizing cycle and using a dishwasher cleaner tablet approved by the manufacturer.
- Sanitize all baby bottles.
- To wash dishes by hand:
- Wash and rinse the dishes as you normally would using hot water.
- In a separate basin, add 1 teaspoon of unscented household liquid bleach for each gallon of warm water.
- Soak the rinsed dishes in the water for at least one minute.
- Let the dishes air dry completely before using again.
Laundry
Washing Clothes (Assuming the drinking water is not discolored or turbid)
- Assuming the water is not discolored or turbid, it is likely safe to wash clothes as usual, but I would clean the unit by using chlorine or a citric acid cleaner or a clothes washer cleaner tablet approved by the manufacturer.
Do Not Drink Water Advisory
Local health authorities issue a do not drink water advisory when your community’s water is, or could be, contaminated with harmful chemicals and toxins, and when boiling water will not make it safe.
Authorities may recommend limited use of tap water for some tasks, depending on the harmful chemical or toxin contaminating the water. Follow health officials’ advice carefully to protect your health and your family’s health.
During a do not drink water advisory, use bottled water for: drinking and cooking, brushing teeth, washing fruits and vegetables, preparing food, mixing baby formula, making ice, and drinking water to pets and livestock.
In some instances, it will be safe to wash hands, flush toilets and shower; in other instances, it will not. You should be cautious when bathing a baby and young children; they might swallow water.
Do not drink or use water from any appliance connected to your water supply lines. This includes the water and ice dispensers in your refrigerator, freezer and dishwasher.
Do Not Use Water Advisory
Local health authorities issue a do not use water advisory when your community’s water is, or could be, contaminated with germs, harmful chemicals, toxins, or radioactive materials. Under this advisory any contact, even with the skin, lungs, or eyes, can be dangerous. Do not drink or use tap water from the impacted system for any purpose as long as the advisory is in effect, including for bathing. These types of advisories are rare.
EPA Health Advisory (HAs)
HAs primarily serve as information to drinking water systems and officials responsible for protecting public health when emergency spills or other contamination situations occur. The Safe Drinking Water Act (SDWA) authorizes EPA to issue HAs for contaminants that are not subject to a National Primary Drinking Water Regulation (NPDWR) (Source: 42 U.S.C. §300g-1(b)(1)(F)). HA documents provide technical information on chemical and microbial contaminants that can cause human health effects and are known or anticipated to occur in drinking water. HA values/levels identify the concentration of a contaminant in drinking water at which adverse health effects and/or aesthetic effects are not anticipated to occur over specific exposure duration (e.g., 1 day, 10 days, a lifetime).
HA: Health Advisory- An estimate of acceptable drinking water levels for a chemical substance based on health effects information; a Health Advisory is not a legally enforceable Federal standard, but serves as technical guidance to assist Federal, state, and local officials.
“One-day HA: The concentration of a chemical in drinking water that is not expected to cause any adverse noncarcinogenic effects for up to one day of exposure
Ten-day HA: The concentration of a chemical in drinking water that is not expected to cause any adverse noncarcinogenic effects for up to ten days of exposure.
Lifetime HA: The concentration of a chemical in drinking water that is not expected to cause any adverse noncarcinogenic effects for a lifetime of exposure.”

PFAS Contamination and Cost Recovery
By NRWA Cheyenne
On March 4th, 2021
“This report contains important information on PFAS contamination and a cost recovery program for testing, treatment and remediation initiated by the National Rural Water Association on behalf of rural water and wastewater utilities across America.
Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other chemicals. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both chemicals are very persistent in the environment and in the human body – meaning they do not break down and they can accumulate over time. There is evidence that exposure to PFAS can lead to adverse human health effects like kidney damage, cancer, developmental effects to fetuses, and other illnesses.
In 2016, the Environmental Protection Agency lowered the health advisory level from 400 parts per trillion to 70 parts per trillion. Since that change was made, states have taken independent actions ranging from the adoption of the recommended health advisory level of 70 ppt to a much lower allowable level. As a result, systems of all sizes are experiencing increased cost for testing treatment and remediation. At the same time, the EPA has made PFAS contamination a priority and action has been taken to label PFAS as a hazardous substance. This will impact wastewater utilities and the disposal of bio-solids into a hazardous landfill if PFAS is detected.
In 2019, the National Rural Water Association recognized the financial burden on systems and joined the law office of Napoli Shkolnik PLLC to bring these systems together that have concerns or have been affected by PFAS contamination. This potential landmark contamination case could help water and wastewater systems recoup money spent on treatment and remediation. The sole purpose is to allow utilities the opportunity to recover their cost associated with testing, treatment and remediation with no upfront cost to the utility.
It is recommended that utilities register for cost recovery if they have tested and detected PFAS at any level or if the water source is near a potential PFAS contamination site. These sites include, but are not limited to, airports, military bases, fire training activity areas, landfills and/or manufacturing facilities. There are three key points to this action:
- The action is for cost recovery as opposed to punitive and is filed against the global manufacturers of the compounds, not any local companies who may have used them.
- There are no upfront costs to the utility to register for cost recovery.
- Once a settlement is reached, the utility has the option of accepting the settlement or declining.
Utilities can find more information about PFAS contamination here and register for cost recovery here.”
Note:
1. This is one reason the EPA should not set a formal standard.
2. The second reason – once it is removed from the water – where will it go and who will be responsible for this stuff??
3. Why we suggest ordering a Neighboorhood Hazard Reports

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).

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.
