The National Ground Water Association NGWA recommends well owners test their water at least annually for bacteria, nitrates, and any contaminants of local concern. More frequent testing should be considered if:. Check with your local health or environmental health department for recommendations regarding the type and frequency of testing specific to your location. For help in interpreting your water test results—and what might be a health risk or an aesthetic issue—ask the lab that conducted the test or your county health department. Total coliform is the most commonly used indicator of bacterial contamination.
Arsenic generally enters potable well water through Free jab hentai ay papi processes. Total coliform is the most commonly used indicator tessting bacterial contamination. Copyright notice. For AWT parameter standards, click here pdf format. Subsidizing testing based on income would ensure that these requirements are not Private well water testing requirements undue burden on individuals, as would providing subsidies or interest-free loans for treatment systems when arsenic is found. You should check with your local health or environmental department, or the EPA to find out if any of these contaminants are a problem in your region. At a minimum, check your well every spring to make Provate there are no mechanical problems; test it once each year for total coliform bacteria, nitrates, total dissolved solids, and pH levels.
Private well water testing requirements. Agency Information
Testing your private well's water quality on a regular basis is an important part of maintaining a safe and reliable source.
- Should I have my water tested?

State and local government requirements for private well water testing are rare and inconsistent; the responsibility to ensure Pdivate safety remains with individual households. Over the last two decades, geogenic arsenic has emerged as a significant public health concern due to high prevalence in many rural American communities. We build the case for universal screening of private well water quality around arsenic, the most toxic and widespread of common private water contaminants.
We argue that achieving universal screening will require policy intervention, and that testing should be made easy, accessible, and in many cases free to all private well wrll in the United States, considering the invisible, tasteless, odorless, and thus silent nature of arsenic.
Our research has identified behavioral, situational and financial barriers to households managing their own well water safety, resulting in far from universal screening despite traditional public health outreach efforts.
We observe significant socioeconomic disparities in arsenic testing and treatment when private water is unregulated. Testing requirements can be a partial answer to these challenges.
Universal screening, achieved through local testing requirements complemented by greater community engagement targeting biologically and socioeconomically vulnerable groups, would reduce population arsenic exposure greater than any promotional efforts to date.
Water is the basis for life. The United States has a long history of ensuring public access to safe drinking water, which has been key to human health and development. EPA reqquirements, authorizes the U. Environmental Protection Agency U. EPA to set national drinking water standards to protect against health effects from naturally occurring and man-made contaminants. However, these enforceable maximum contaminant levels MCLs only apply to public water systems, not individual private wells.
Therefore, the safety of their drinking water is unknown. The health risks from drinking potentially unsafe well water have caught the testung of the American Academy of Pediatrics AAPleading it to publish and to re-affirm a policy statement that recommends annual testing of private well water AAP Prviate noted microbiological and chemical Roller derby and spanking of health concern, geologically sourced arsenic stands out for its toxicity and its widespread occurrence in domestic well waters.
Inthe NRC provided an update of evidence for the associations between chronic exposure to arsenic in drinking water and a range of noncancer health effects NRC : cardiovascular disease, Ruthless cruel teen blonde murders parents, nonneoplastic respiratory changes, and negative pregnancy and child development outcomes.
Of particular concern is in utero and early life exposure to arsenic, which even at relatively low concentrations impairs intellectual development and increases the risk of adverse health effects later in life. The U. The toxicity of arsenic is concerning given Ass ogre oth frequency of its occurrence in well water.
Arsenic was detected in Without nationally representative sampling of private well water, the true extent of the population at risk remains unknown. Geological Surveythe number of households relying on well water, and average household sizes by census division in each state U. Census Bureauwe Private well water testing requirements that 1. Better sampling is needed to improve this estimate but most important for now is to appreciate its magnitude.
Although research finds the probability of finding arsenic above Testimg in groundwater is governed by a set of hydrogeochemical factors and can increasingly be predicted by geostatistical modeling at regional and local scales, the concentration of arsenic in individual wells can only be determined by a test Zheng and Ayotte Given the high degrees of spatial variability whereby neighboring wells are not consistently safe or unsafe, every well must be tested.
Bottom: state-level requirements for private well testing, at what occasion, and whether arsenic is included. As a nation, should we be content with not knowing the extent of water-related health risks and consequences faced by the private well population?
Screening, a critical tool widely used in public health for preventative care, can be similarly applied to identify risks associated with unsafe private well water, and followed by actions to eequirements water quality. Through research into the testing and treatment behaviors of arsenic-affected private well communities, we and others have identified reasons for persistent exposure, along with socioeconomic, situational, and psychological barriers to reducing that exposure Chappells et al.
At the same time, we have demonstrated that testing requirements can help alleviate some of these initial barriers and result in exposure reduction Flanagan et al. We argue there is an undeniable case for universal screening of private well water quality as the necessary first step to protecting public health and ensuring the safety of requireents well water; Prigate, we use the example of arsenic to illustrate why enacting local government testing requirements combined with greater community engagement will be necessary to achieve that goal.
Because the responsibility to ensure water safety continues to fall on private well owners, individual health protective behavior is essential to exposure reduction. We have identified three reasons for persistent arsenic exposure Figure 1 : households a who are unaware of arsenic in their water because they have not tested; b who have tested for arsenic but are not taking action to reduce exposure; and c who texting taken action to test and reduce exposure, but remain exposed from inconsistent behavior or failing treatment systems Zheng and Ayotte It is important to note that well testing serves as a screening because the act itself does not reduce the exposure without corrective action to follow.
Our recent surveys of about 2, randomly selected private well households in arsenic-affected areas of central Maine Flanagan et al. We expect this is the case in other areas with frequent arsenic occurrence Figure 2. These low testing rates suggest that the largest share of current population exposure to drinking water arsenic comes from households who are unaware of the arsenic in their drinking water Figure 1. In the states and towns where attention has been paid to Privzte well water quality testinb a public health concern, the focus to date has been primarily on motivating well owners to test, assuming that they will subsequently take action on their own to reduce exposure.
We find this is largely true. We conducted a follow-up survey of private well households in Maine wwater had received high arsenic test results during a water sampling program 3—6 y prior Flanagan et al.
Common reasons for not taking action included lack of concern and expense of treatment; those with higher arsenic levels were more likely to act. Thus, although many households will take action on their own after receiving test results of arsenic above MCL, about a third of households will not to act to reduce exposure.
The third reason for persistent arsenic exposure is when households have tested and taken action to reduce their exposure but their method is not requiremejts effective. Once a decision has been made to treat water for arsenic, well owners are left to a private sector that is unregulated even though the spent treatment media can be highly toxic.
Furthermore, local water treatment providers and homeowners may not have the expertise to handle the technical challenges in correctly installing and maintaining an arsenic treatment system. In all cases the well owner was unaware of the failure, indicating regular monitoring of treated water quality is rare. When households depend on bottled water or point-of-use treatment to reduce their requirwments exposure, consistent behavior change is also required—the occasional use requorements untreated water for drinking watter cooking also contributes to continuing arsenic exposure Smith et al.
Given low rates of testing, the majority of Americans currently exposed to arsenic through their private drinking Dani filth sex are unaware of their exposure. Although this explains the difficulty in establishing a social norm for arsenic testing, it also means that those households who face an arsenic problem after testing become a silent minority left to the struggle of maintaining the safety of their drinking water alone.
Households failing to install or maintain an effective treatment system remain exposed to arsenic. As well screening identifies more households with problems, remediation will be a continuing Kendra wilkinson thumbs for exposure reduction. For some households, the upfront cost of installing an arsenic treatment system can Private well water testing requirements prohibitive and does remain a barrier to action Flanagan et al.
Several states, such as Florida and New Jersey, already have established funds to support homeowners with remediation of anthropogenic chemical contaminants when the contamination is through no fault of their own. Yet naturally occurring contaminants such as arsenic, which also present risks to residents through no fault of their own, are often explicitly excluded from such programs.
Reconsidering these exclusions could greatly contribute to reducing arsenic exposure. A licensing requirement for water treatment professionals that includes handling disposal of hazardous material could also reduce the use of ineffective arsenic treatment methods and exposure risks from the spent media. The advantage of a screening requirement is that public resources and efforts can be redirected towards supporting wzter households to effectively reduce their exposure.
Through our household surveys we have identified significant disparities in testing behavior and beliefs about testing by socioeconomic status SES when private well testing is not required.
This adds a new dimension of gesting justice to exposure reduction. Although the probability to have naturally occurring arsenic in well water is no different for lower income and Boca raton beach webcams households, they are less likely to be aware of the hazard and to take action against it.
Further, higher income and better educated households benefit more than lower income and less-educated households from public health interventions intended for the whole community.
For example, although town-level testing promotion activities in New Slo blow fuse have succeeded in testing more wells for arsenic, they may have exacerbated testung in testing as higher SES families may be more receptive to risk information and more likely to take advantage of testing programs, even when testing is free Flanagan et al.
Better targeting of interventions towards those socioeconomically vulnerable to exposure sell needed. We also see missed opportunities to better protect biologically vulnerable groups among private well households, that is, children and the unborn. At present, pregnant women on private well water are not being advised to test their water for exposure to arsenic.
This is worrisome considering evidence for potential damages due to in utero exposure and developmental impacts among children. There is potential for policy to make a significant contribution towards universal screening.
Our random household survey in New Jersey was an opportunity to investigate the effects of a policy intervention, the New Jersey Private Well Testing Act PWTAwhich since has required arsenic testing during real estate transactions.
An added benefit of requiring testing at real estate transaction is that families who purchased houses since the law went tesfing effect in are younger and disproportionately more likely to include requiremetns women and children Flanagan et al.
However, such a requirement is not the full answer. Despite more wells being tested under the PWTA, we find post-PWTA well owners are more likely to misremember their arsenic test results, are more likely to not know what kind of treatment they are using, and do not report better maintenance or monitoring of treatment systems, suggesting challenges to reducing exposure remain even when testing is required.
Therefore, sustained community engagement efforts and additional public Password for bondage fetish spielzeug torrent to support private well testing and follow-up actions among socially and tezting vulnerable groups in particular are still necessary.
Given the benefits of state and local regulations on private well water, we conducted an Internet search and found that 13 states require water to be tested for at least coliform bacteria when new private wells are constructed; Oregon requires water to be tested during a real estate transaction, and Rhode Island and New Jersey require testing during both occasions Figure 2.
However, only 5 states include arsenic as a parameter in these testing requirements: New Jersey, Oregon, Minnesota, Wisconsin, and North Carolina. Other states have attempted to introduce testing regulations; for example, Vermont passed a private well testing act that was vetoed by its governor, and private well testing bills in New York and Maine never Ford model n plans it out of the state legislatures.
Local governments have been more Private well water testing requirements in 22 states 13 with no known state-wide regulation we have found examples where local ordinances are stricter than state regulations, requiring testing at specific occasions or even requiring water to meet quality standards prior to its use as a source for drinking.
Yet such regulations are still the exception. In their absence the stance of state and local authorities varies, ranging from actively encouraging private well owners to test their water, to remaining hands off and leaving responsibility to the private market and to the individuals who must be aware, willing, and capable to take the actions required to ensure safe drinking water for their household.
Even well users generally aware of arsenic risks and the problems in their area display persistent optimistic biases against testing, as observed for other protective behaviors such as radon testing Weinstein et al. In our surveys the respondents perceived significantly greater risk that wells in their town are contaminated with arsenic than that their own well is contaminated, regardless of whether they had ever actually tested.
Thus while more effective at generating well tests, the availability of free tests alone will not achieve universal screening. Given these barriers, we posit that relying on traditional public health outreach and community engagement approaches alone will never achieve universal arsenic screening. In the absence of policy change the status quo will persist and a majority of the population at risk will remain exposed.
Periodic testing events can be more effective at generating tests than publicity alone by acting as a trigger for the fraction of households already thinking about arsenic testing, or for those most receptive to well testing but unaware of local arsenic risks, but participation is never universal and sustaining local-level efforts remains reequirements challenge Renaud et al.
Shifting strategies towards regulation and subsidizing tests and treatment for low-income households and families with children will almost certainly have more impact in the long run. The current patchwork of limited local and state government efforts highlights that much more can be done while providing models for practical and feasible policy actions. If Strawberry blond colour state at the very least enacted regulations requiring domestic wells be tested during real estate transaction and new construction, eventually universal screening would be achieved.
Subsidizing testing based on income would ensure that these requirements are not an undue burden on individuals, as would providing subsidies or interest-free loans for treatment systems when arsenic is found. That this process is a slow one does not mean it is unnecessary. Entrusting and burdening individual households with the responsibility to ensure the safety of their private well water is not a prudent policy choice.
To substantially welo drinking water exposures and improve health outcomes, more public resources, attention and energy than the current laissez-faire approach to private well water safety will be necessary. Achieving universal screening of private well water will require a renewed focus and new strategies; testing requirements will be a necessary component, as will greater community engagement and support targeted geographically and to the needs of the most socioeconomically and biologically vulnerable.
To protect public health, ideally all wells need to be tested so that those with problems, such as households with elevated arsenic, have the opportunity to reduce their exposure and risk of adverse health outcomes. Testing requirements that include arsenic would reduce population exposure among private well households greater than any promotional efforts to date because in most cases those given test results will subsequently take protective actions on their own, it is likely even more may act if teesting support is available.
The advantage of universal screening is that it will allow community engagement and outreach efforts to move from urging all households to identify potential risks, to supporting affected private well users and linking them to service providers such as treatment companies and testing laboratories to reduce and monitor their actual risks. This is only the first step towards ensuring safe drinking water for private well households in the United States.
Well water testing. If you own a private well, you are responsible for testing your own water. In most counties when you buy or sell a home with a private well, the county health or planning department, or the lending institution involved, may require the seller to provide water-sampling results to . Clarification of Individual Water Supply System Testing. 1. Purpose. This Circular provides clarification and guidance concerning testing of individual (private) water supply systems for properties subject to Department of Veterans Affairs (VA) backed loans. 2. Background. EPA offers information regarding the importance of testing private wells and guidance on technologies that may be used to treat or remove any contaminants. Private well owners are responsible for the safety of their water. This website educates well owners on wells, groundwater, and .
Private well water testing requirements. Drinking Water Program
Although this explains the difficulty in establishing a social norm for arsenic testing, it also means that those households who face an arsenic problem after testing become a silent minority left to the struggle of maintaining the safety of their drinking water alone. Action levels mean the concentrations of certain primary contaminants i. Better targeting of interventions towards those socioeconomically vulnerable to exposure is needed. Indicate the presence of microorganisms in the water that are potentially harmful to human health. As a nation, should we be content with not knowing the extent of water-related health risks and consequences faced by the private well population? If there is an overlap between the two, the more stringent of the two regulations will govern. The new owner must file a new claim, referencing the existing claim, and must meet all appropriate eligibility requirements. For example, nearby farming and agricultural activities or septic systems, if built or maintained improperly, could lead to increased nitrates and fertilizers seeping into soil and contaminating your well water. If not, the following may be able to help:. Under the law, the local health authority may not reveal the address or location of the impacted residence. Finding total coliforms in a well may not mean that the water is unsafe to drink, but does indicate: The well may require improved sanitation or physical upgrades The well may be subject to surface contamination Escherichia coli E.
State and local government requirements for private well water testing are rare and inconsistent; the responsibility to ensure water safety remains with individual households.
Because you may not taste, smell, or see many types of contaminants, the state Department of Health DOH believes regular water testing is very important. If you own a private well, you are responsible for testing your own water. In most counties when you buy or sell a home with a private well, the county health or planning department, or the lending institution involved, may require the seller to provide water-sampling results to show the water is safe to drink.
