Surface Water: What You Need To Know

Surface Water: What You Need To Know

 

Analies Dyjak | Policy Nerd   

Surface water is an extremely important natural resource. From the water we drink, give to our pets, and use for recreation, we are dependent on its various uses. Surface water is continuously being threatened by anthropogenic activities. It’s extremely difficult and costly for municipal treatment facilities to keep up with new contaminants that are polluting waterways every single day. Additionally, federal regulations don’t reflect the large scope of surface water pollution. This blog post discusses the various threats to surface water and why humans should care.

What Is Surface Water?

Lakes, oceans, streams, rivers, ponds, reservoirs, and wetlands are the various types of surface water. Freshwater sources are responsible for providing potable drinking water to 84% of the nations population. Surface water is different from groundwater because it has the ability to disperse and become diluted as it travels throughout a body of water.  Groundwater aquifers are essentially holding tanks for highly concentrated contamination. There’s less room for contaminants to move around, and less volume for the contamination to become less concentrated. 

How Does Surface Water Become Polluted?

Surface water is extremely susceptible to pollution because it occupies such a large portion of the earth’s surface. Surface water pollution is almost entirely the result of human activities. Agriculture, mining, factory effluent, landfills, human/animal waste and localized pollution are just some of the most common sources of surface water pollution. Topography and geological formations create natural surface water runoff, but human manipulation of the land increases flow rates and overall contamination.

  • Point source pollution comes from an easily identifiable source, like a factory or sewage treatment plant. Point source pollution is discharged through a pipeline, ditch, or any “discrete conveyance” that directly or indirectly enters a body of water. Point sources are typically regulated by National Pollutant Discharge Elimination System (NPDES) permits.

  • Non-point source pollution is much harder to regulate because the source is not easily identifiable. Agricultural and stormwater runoff are the two most common types of nonpoint source pollution. Heavy rain events cause contaminants to runoff from roads and fields, collecting debris and pollution as it travels into a body of water.

How Do You Mitigate Surface Water Pollution?

It’s expensive and nearly impossible to mitigate a contaminant once it has entered surface water. For some contaminants, the solution is typically self-mitigating. A contaminant will become diluted to extremely small concentrations after it has traveled and dispersed throughout a body of water. Additionally, some contaminants are still extremely toxic at very small concentrations. There are also several persistent contaminants that never fully decompose in nature (PCBs, DDT and Dioxin), or take hundreds of years to degrade. As we’ve seen in Wilmington, North Carolina, and Maplewood, Minnesota, municipal water treatment facilities are only equipped to remove certain types and quantities of surface water contamination.

What Is Currently The Biggest Threat To Surface Water?

Man-made compounds are one of the largests threats to drinking water sources. Per and Polyfluoroalkyl Substances (PFAS) are a category of man-made “emerging contaminants,” which means they have been detected in the environment but the risk to human health is not well-understood. Chemicals such as GenX, PFOA, and PFOS are all common contaminants that fall under the category of PFAS. DuPont, Chemours, and 3M have been using variations of these chemicals in industrial and consumer products since the early 1950’s. Scotchgard, Teflon, firefighting foam, metal plating, heat/water repellent chemicals, and stain resistant fabrics are common uses of PFAS. They are extremely persistent in the environment, which means they do not readily degrade. PFAS effluent is either directly dumped from a factory into surface water or a dug ditch, which will then percolate into groundwater. This is allowed because PFAS are unregulated by the federal government.

North Carolina’s Cape Fear River has been unknowingly  experiencing surface water contamination for years. A Chemours plant located in Fayetteville, North Carolina, had been discharging various types of PFAS into the Cape Fear River since the 1980's.  The Cape Fear is the primary drinking water source for residents of Brunswick and New Hanover County. Their water resource is now tainted with a dangerous contaminant that's unregulated by the federal government. 

Algal Blooms and Surface Water

Algal blooms are another major threat to surface water. An influx of nutrients or heat can increase the quantity of algae. Often, this overload of nutrients is the result of agricultural fertilizer runoff. Harmful Algal Blooms or HABs occur after an influx of nutrients or a sudden increase in water temperature. HABs can then produce cyanotoxins, which are harmful to humans and the environment.

How Can I Protect Surface Water?

Protecting surface water from contamination will not only improve drinking water quality, but also valuable habitats. Here are some tips for local level surface water management:
  • Watershed Management: Municipalities should look at watersheds as an entire system, rather than exclusively a water resource. Watershed management surveys the land surrounding a body of water to determine the natural flows and influxes.
  • Eliminating Pesticides, Herbicides, and Fertilizers: What’s bad for plants and animals, is also bad for humans. This category of surface water pollution runs-off directly into surrounding bodies of water and effects fragile surface water ecosystems. Reducing or eliminating the use of pesticides, herbicides, and fertilizers will reduce the amount of necessary additives by municipal water treatment facilities to eliminate contaminants.
  • Reduce Impervious Surfaces: Impervious surface is any type of ground cover that prevents water from infiltrating into the ground. Pavement or asphalt is the best example. Impervious surface increases runoff flow rates into surface water, and prevents groundwater from naturally filtering contaminants. Next time you’re thinking about paving your driveway, consider a pervious alternative such as porous asphalt or pervious concrete.
  • Hold Municipalities Accountable: Stay current with commercial and industrial development within your community. Public comment periods are required prior to development and prior to obtaining a NPDES permit. Companies are required to address each question and concern individually, so if development plans raise personal concern, don’t be afraid to utilize the public comment period.

    Military Bases Have High Concentrations of Per and Polyfluoroalkyl Substances (PFAS)

    Military Bases Have High Concentrations of Per and Polyfluoroalkyl Substances (PFAS)

    ***Updated 8/29/18 to include video***

    Analies Dyjak | Policy Nerd   

    Per and Polyfluoroalkyl Substances (PFAS) have been receiving a ton of media attention throughout this past year. PFAS are a category of toxic contaminants that have invaded public and private drinking water systems across the entire country. Military bases are extremely susceptible to this type of contamination because of necessary on-base activities. If you would like to learn more about what PFAS are, their health effects, and if they're regulated, please click here. 

    Why Do Military Bases Have High Concentrations of Per and Polyfluoroalkyl Substances (PFAS)?

    Military bases have historically had issues with pollution, due to the nature of on-base activities. Municipal fire departments also travel to nearby military bases because they provide an open, secure area to train. So not only are military personnel being directly exposed to PFAS, but so are local fire departments. The Department of Defence isn’t necessarily to blame for the high rates of contamination on military bases. The Manufacturers of PFAS-containing fire fighting foam who actively sell to the DOD are greatly at fault. Because there is no effective alternative on the market, the military has no choice but to continue purchasing and using these products. Unlike many other countries, the United States doesn’t use the precautionary principle in chemical manufacturing. This means that chemicals are introduced to the market before toxicological due diligence is completed. Most of the time it takes someone getting extremely sick for manufacturers to even begin to pay attention.

    More often than not, military bases have their own underground private wells that provide drinking water to families living on base, rather than being apart of a public drinking water system. Fire fighting foam can either directly percolate into soil, or run off into surrounding surface water sources. Water from contaminated soil naturally recharges on-base drinking water wells, which families consume on a daily basis.

    What Is The Department of Defense Doing About Per and Polyfluoroalkyl Substances (PFAS) on Military Bases?

    The most recent data provided by the DOD stated that 99% people receiving non-DOD-treated water were served by systems with no violations, whereas only 89% of people receiving DOD-treated water were served by systems with no violations. It’s important to note that these data are from bases that voluntarily tested for PFAS, but they do however reiterate that military bases have higher concentrations of this contaminant than other areas in the country. In October of 2017, the US Government Accountability Office reported that the Department of Defense has taken action on PFAS. DOD has directly shut down wells or provided filtration to 11 military installations. This is definitely a step in the right direction, but there are over 400 military bases in the United States that are still contaminated. Approximately 3 million people in the US drink water provided by the DOD. Not only are active military personnel at risk, husbands, wives and children and are being adversely impacted by PFAS. Again, manufacturers of these dangerous chemicals are mostly to blame for such high concentrations of PFAS contamination in drinking water.

    What Are Public Officials Doing About Per and Polyfluoroalkyl Substances (PFAS)?

    EPA set a Lifetime Health Advisory Level of 70 parts per trillion for both PFOA and PFOS. The rule of thumb for PFAS is that the sum of the category of contaminants should be no higher than 70 parts per trillion. ATSDR believes this level should be reduced to 20 parts per trillion for drinking water. Again, Lifetime Health Advisory Levels and Minimum Risk Levels are non-enforceable limits that municipalities are not required to follow. DOD has not developed their own standard for PFAS in drinking water and therefore follow the non-enforceable national level of 70 parts per trillion. DOD is not at all incentivized to create a standard or even test for PFAS, because of the outrageous mitigation expenses.

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

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

    How Are We Exposed To Arsenic?

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

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

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

    Arsenic Toxicity

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

    What Can I Do To Reduce My Exposure To Arsenic?

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

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

    Whole House Filters

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

    Point Of Use Water Filters For Arsenic

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

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

    Key Things To Know About Getting Your Water Tested

    Key Things To Know About Getting Your Water Tested

    How Is Drinking Water Regulated?

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

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

    How Often Should Home Water Testing Be Conducted?

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

    What Are The Most Common Types Of Drinking Water Contaminants?

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

    Total Coliform

    E.coli

    pH

    Nitrate-N

    Nitrite-N

    Copper

    Iron

    Manganese

    Fluoride

    Uranium

    Sodium

    Radon

     

     

     

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

    What Is The Process For Analyzing Drinking Water?  

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    5 Things To Know About Arsenic In Drinking Water

    5 Things To Know About Arsenic In Drinking Water

    Eric Roy, Ph.D.  | Scientific Founder  

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

    Why Should I Care About Arsenic In Drinking Water?

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

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

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

    How Does Arsenic Contaminate Drinking Water?

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

    Map Of Arsenic Concentrations In Groundwater

    How Much Arsenic Is Toxic?

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

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

    What Can I Do To Reduce Exposure To Arsenic?

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

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

    Whole House Filters

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

    Point Of Use Filters

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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