Perchlorate EPA Seeks Input on National Primary Drinking Water Regulation Contaminant Perchlorate
WASHINGTON (October 3, 2024) – The U.S. Environmental Protection Agency is inviting small businesses, governments, and not-for-profit entities to participate as Small Entity Representatives (SERs) providing advice and recommendations to a Small Business Advocacy Review (SBAR) Panel. This SBAR Panel will focus on the agency’s development of a rule that will regulate perchlorate in drinking water to protect public health.
EPA is developing a National Primary Drinking Water Regulation (NPDWR) for the chemical contaminant perchlorate (ClO4–) under the authority of the Safe Drinking Water Act (SDWA) and as required by court orders. EPA has committed to issuing a proposed NPDWR for perchlorate by November 2025 and a final regulation by May 2027.
The Regulatory Flexibility Act requires agencies to establish an SBAR Panel for rules that may have a significant economic impact on a substantial number of small entities. The SBAR Panel will include federal representatives from the Small Business Administration (SBA), the Office of Management and Budget (OMB), and the EPA. The Panel members ask a selected group of SERs to provide advice and recommendations on behalf of their company, government, or organization to inform the Panel members about potential impacts of the proposed rule on small entities.
The EPA seeks self-nominations directly from the small public water systems (serving 10,000 or fewer people) that may be subject to the rule requirements. Other representatives, such as trade associations that exclusively or at least primarily represent potentially regulated small public water systems, may also serve as SERs.
Self-nominations may be submitted through the link below and must be received by October 7, 2024.
Nominate yourself as a SER.

Over Pumping Well Water Causes Problems – Low Yield Well – Can your water well be over-pumped?
Over Pumping Well Water Causes Problems – Low Yield Well – Can your water well be over-pumped?
By Mr. Brian Oram, Professional Geologist
The simple and direct answer is Yes. A water well can be over-pumped and when this occurs the actions can cause premature failure of pumps and motors, damage the wellbore integrity, decrease the wellbore yield, impact produced water quality, and ultimately decrease rate of production.
In most cases when a new well is drilled, the well driller reports the blown yield of the well. This is typically the amount of water the driller can physically blow out the top of the well over a short period of time or in a very few cases this may be the rate they were able to pump from the well for a short time period. This period of time is multiple hours, but more likely at most 1 hour. This is not the long-term sustainable yield from the well and in many cases, this is all the water that was in the well.
The Know Your H20 program is based in Northeastern Pennsylvania and we have worked on a number of cases where the actual well yield of the well was significantly less than the blown yield for the well over the last 30 years. One example: (look for the red flags)
Well Case 1- Pocono Vacation Home (2nd Home)
This well is used intermittently during the year and used mostly over long weekends during the summer and ski season. The well was drilled by a licensed well driller, but the pump/motor was installed by the home builder. The well was 150 feet deep and reportedly the well had a blown yield of 10 gpm. The well was serving 1 single family home (3 bedrooms) and the peak water usage should be equivalent to about 400 gpd.
We (Keystone Clean Water Team) were called out because the homeowner was getting very dirty water that contained a lot of “gas” and at sometimes no water. We looked at the available well log for the well and drillers notes and we found the following:
- Primary water bearing zone was at 100 feet, static water level at 45 feet top of casing (toc), and a blown yield (15 minutes) of 10 gpm. We searched and found the actual drillers log in the PAGWIS Database.
- Pump was set at 120 feet or 20 feet off the bottom of the well. Note: Is not a good idea to install a pump below the primary water bearing zone. We got to review the actual plumbers bill and notes on the pressure tank.
- The pump that was installed was rate at 10 gpm, but from the pump curve this rate would apply to a dynamic water level of 120 feet and not the more likely dynamic water level of about 80 feet or 20 foot above the water bearing zone. Therefore, the pump would initially pump at a rate greater than 10 gpm for some period of time.
These observations suggested that one of the problems was the well was being over-pumped. After we investigated, this is what we found:
- The actual static water level in the well was not 45 feet top of casing, but 80 feet top of casing. We used a sonic water level sensor.
- We camera surveyed the well and tested the water and found that a bioslime layer and scale coated the fractured zone.
- We filled the borehole with water to 45 feet toc and turned on the pump and discovered that the pump was actually pumping at a rate of 15 gpm and not 10 gpm and if permitted the dynamic water level would drop to 130 feet toc. This means that the dynamic or pumping water level was below the point that groundwater would enter the borehole. This means that the aquifer was no longer acting like a confined aquifer under pressure, but the aquifer was being drained. We confirmed the well was being over-pumped.
We were correct the well is being over-pumped and the well also has a problem with bioslime/ scale formation. Our first action item was to clean out the well and do some basic well development to increase the well conductivity and yield. After cleaning out the wellbore and fractured zone using a combination of chemical cleaning and surging, the static water level was about 50 feet toc. We then conducted a step pumping test that lasted a total of 4 hours and estimated that the “safe yield” of the well was more like 5 gpm and not 10 gpm. We recommended that the pump be changed and the pump be set at a depth that could not draw the water below the water bearing zone.
Summary : Therefore, what we really had was a low producing well that was not properly identified originally and then the pump installer (not the well driller) installed a pump with an excessive pumping rate at a depth that did not protect the aquifer.
Because this article is really about low producing water wells, we went looking for solutions and found “EPP Well Solutions” – https://eppwellsolutions.com/well-health and their article on “Well Health”. A few quotes from this article that we found most helpful:
“Over pumping is a common factor with the low water well. A well is over-pumped if the water is withdrawn at a faster rate than the well was designed for or the aquifer is able to produce. Over-pumping is the most common well problem that leads to premature well failure. Over-pumping not only depletes the groundwater aquifer (or source), but it rapidly increases the rate of corrosion, incrustation, and biofouling related problems. Over-pumping also increases the rate of sediment particles moving toward the well, causing plugging of the perforated area where water flows into the well. It can also cause the aquifer to settle and compact which further restricts water flow to the well.”
In the article, they highlighted the problems that might occur with over-pumping a well, which were perforation plugging (slotted casing), mineral incrustation, and biofouling. One that was not mentioned was natural decrease in aquifer porosity and conductivity. In the case of our example, the aquifer was a confined aquifer under artesian pressure, which means that the pressure of the water in the formation were helping to keep the fractures open along the borehole walls. When the well was over-pumped and the water was permitted to cascade into the well, this means that the weight of the earth and rock above the fracture could cause the fracture to partially close.
The typically solution to a problem with low yield wells are as follows:
- Drill more than one well or attempt to modify the well by drilling deeper or hydrofracturing the well.
- Installing some internal storage within the system, i.e., a storage tank and then using a second set of pumps to re-pressurize the system.
- Supplementing the system capacity with surface water or a rainwater harvesting system.
EPP Well Solutions have developed a hybrid option using the Water Harvester System. “The Well Harvester automatically harvests the water in the well while preventing the well from over-pumping itself. The harvested water is then pumped from their system into the house. Their system is compact and can fit in most garages or well houses and is able to harvest and store 215 gallons (or more with additional tanks) for use throughout the day. “
If you suspect you have this problem, we would recommend you review EPP WELL Solutions educational videos. In addition, the company has a really interesting Emergency Well Hand Pump System.

Alkaline Drinking Water Health Benefits Make Alkaline Water at Home
Make Your Own Alkaline Water at Home – Go Bottleless !
Alkaline water is slightly less acidic than regular drinking water and contains alkaline minerals with a pH > 7. Alkaline water has a higher pH level than most tap water and well water sources that are used for drinking water. In fact, in Pennsylvania, a primary problem with well water is that water is acidic and corrosive to the piping and it is recommended that a whole-house water treatment system a neutralizer be installed. Most tap water has a pH from about 6.5 to 7.5, but alkaline water may range from 8 to 9. Alkaline water tends to have a high alkalinity and mineral content that includes calcium and magnesium as the dominant positive cations, but in some cases a natural water may be high in sodium or potassium. As the pH of the water increases, the redox potential (Eh) of the water becomes more negative, but the degree of change is not just a function of the pH it depends on the water ionic chemistry.
In drinking water, “redox potential is a measure of the tendency of the solution to either gain or lose electrons in a reaction. A solution with a higher (more positive) reduction potential than some other molecule will have a tendency to gain electrons from this molecule (i.e. to be reduced by oxidizing this other molecule) and a solution with a lower (more negative) reduction potential will have a tendency to lose electrons to other substances (i.e. to be oxidized by reducing the other substance).” (Source: Wikipedia) The redox potential of the water can be measured using an 0xidation‐Reduction Potential (ORP) sensor. The Eh of the water is related to the ORP measurement based on the type of sensors used in the ORP meter.
Oxidation‐Reduction Potential (ORP) is a measurement of the relative oxidizing or reducing condition of water and is typically monitored using a handheld voltage meter that measures the electrical potential between a platinum electrode and a reference electrode. When the ORP value is positive this indicates an oxidizing environment while a negative value would suggest a more reducing condition. The Eh, or redox potential, can be used to estimate the reduction potential for your drinking water.
If the sensor is made using an Ag/AgCl reference electrode with a 1 M KCl fill solution the correction factor is + 236 mv.
If the sensor is made using an Ag/AgCl reference electrode with a saturated KCl fill solution the correction factor is + 197 mv.
For example, the Orp Sensor is a platinum ‐ Ag/Ag Cl electrode where the reference electrode is filled with 1 M KCL and you get a reading on the sensor of – 125 the actual EH of the fluid is:
-125 mv + 200 mv = 75 mv
DIY Alkaline Water systems are designed to initially provide a physical barrier to remove contaminants and purify the water to remove chlorine by-products, particles 5 micron or greater, and heavy metals. An alkaline water system manufactured by Crystal Quest has a GAC and anionic resin to pesticides & herbicides, volatile organic compounds, pharmaceutical by-products & other inorganic substances such as petroleum byproducts. The final filter increases the calcium and magnesium content of the water and the water pH.

Controversy
Many health professionals say there isn’t enough research to support the health claims made by alkaline water advocates.
- A study in 2018 on mice suggested alkaline water may help reduce nonalcoholic fatty liver disease symptoms (Source: “Effects of alkaline-electrolyzed and hydrogen-rich water, in a high-fat-diet nonalcoholic fatty liver disease mouse model”)
- A 1999 study showed an “Increased bile acid excretion and reduction of serum cholesterol after crenotherapy with salt-rich mineral water” (Source)
- A 2017 study titled “ Natural mineral waters: chemical characteristics and health effects”, reviewed the potential health benefits and side-effects associated with the consumption of natural mineral water, Bicarbonate mineral water, Sulphate mineral waters, Chloride mineral waters, Magnesiac mineral waters, Fluorurate mineral waters, Ferrous mineral waters, and Sodium-rich mineral water.

- Water Desirable for the Human Body in Terms of Oxidation-Reduction Potential (ORP) to pH Relationship (2006) They proposed a Vital Water that had the characteristics of weakly acidic and weakly alkaline and similar to the pH of human bodily fluids.
- Mineral waters and bone health (2004) “Since potassium and bicarbonate lower renal calcium excretion, and since the latter improves calcium balance, mineral waters rich in bicarbonate and potassium have been tested. Indeed, they lowered renal calcium excretion and bone resorption in short- and medium-term trials, and they could be of particular interest in the prevention of osteoporosis in addition to calcium-rich waters.”

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 .”

Healthy Communities
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 .
Healthy Drinking Water/ Water Initiatives
The Center for Disease Control (CDC) implemented an education and information about healthy water, including drinking water, swimming / recreational water , diseases related to poor sanitation and hygiene and waterborne disease , and and how to make water safe to drink in emergencies for outbreaks, preparedness, and response.
The Know Your H20 Program started our education outreach efforts in 1985 and created a formal program known as the Homeowner Outreach Program in 1989 and part of our program includes educating users about current and historic hazards in their communities (Neighborhood Hazard Report), community outreach efforts, asbestos, “Forever Chemicals (pfos, pfoa)“, and fact based information on drinking water and other environmental contaminants.
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.

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).
Our Motto is ” Learn / Diagnose / Test “
Learn – learn about your source and system.
Diagnose – determine the warning signs or symptoms of a problem and get the water tested and problem diagnosed.
Test – implement an approach to mitigate the problem and test to make sure the problem is corrected.

Asbestos in Drinking Water and Environment
Asbestos is a fibrous mineral occurring in geologic deposits. Asbestos can enter the drinking water through the natural weathering of geological material containing asbestos or for a period of time cement water lines were used that contained asbestos. As the water lines decay, the asbestos enters the drinking water. “Asbestos is a generic term used to describe hydrated magnesium silicate minerals that crystallize as bundles of long, thin fibers which readily separate when broken or crushed. These minerals include chrysotile (serpentine) and fibrous varieties of amphibole group minerals such as crocidolite, amosite, anthophyllite, tremolite, byssolite, and actinolite. The special properties of asbestos — high tensile strength, flexibility, and resistance to heat, chemicals, and electricity — have made it well suited for a number of commercial applications, particularly as fire-resistant tiles and insulation (Source).”
They are found in areas with igneous and metamorphic bedrock. Asbestos exposure has been linked to these manufacturing sectors: shipyards, power plants, chemical plants, oil refiners, and mining. The following trades are more likely to be exposed to asbestos drywall tapers, electricians, firefighters, auto mechanics, and plumbing and heating contractors. This is one reason we suggest you obtain a copy of your Neighborhood Hazard Report and if you are a public water customer to get a copy of your consumer confidence report (see below).
In 1974, the maximum contaminant level goal, i.e., MCLG, for asbestos was 7 million fibers per liter or MFL. In 1992, the Phase II Rules set the drinking water standard at 7 million fibers per liter was adequate to protect human health. Some people who drink water containing asbestos well in excess of the maximum contaminant level (MCL) for many years may have an increased risk of developing benign intestinal polyps.
For large scale water treatment – coagulation/filtration, diatomaceous earth filtration, nanofiltration, and corrosion control with sequestering are commonly used. For residential treatment – the most likely and reliable form of treatment would be a combination of reverse osmosis system that includes a filtration system that removes particles < 1 micron. This would include microfiltration, ultrafiltration & nanofiltration. The appropriate NFS Standards that would apply would be NSF / ANSI 53 and NSF/ ANSI 58.
NSF/ANSI Standard 53: Drinking Water Treatment Units – Health Effects
Overview: Standard 53 addresses point-of-use (POU) and point-of-entry (POE) systems designed to reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl ether), that may be present in public or private drinking water.
NSF/ANSI Standard 58: Reverse Osmosis Drinking Water Treatment Systems
Overview: This standard was developed for point-of-use (POU) reverse osmosis (RO) treatment systems. These systems typically consist of a pre-filter, RO membrane, and post-filter. Standard 58 includes contaminant reduction claims commonly treated using RO, including fluoride, hexavalent and trivalent chromium, total dissolved solids, nitrates, etc. that may be present in public or private drinking water.
other routes of exposure – Airborne
Asbestos dust was been found to have carcinogenic effects. The inhalation of asbestos fibers can cause fatal illnesses like malignant lung cancer, mesothelioma, and asbestosis.
