About an average of 13 million American households owns a private well. Private wells are not subject to federal legislation that apply to public drinking water systems. Thus, it is up to well owners to regularly check the safety of their drinking water. To ensure it is safe for human consumption.
The regulatory reach of the US Environmental Protection Agency (EPA) is restricted to public drinking water systems, which are administered by the federal Safe Drinking Water Act. EPA does not control private wells or publicize criteria or standards, although they give recommendations.
A small number of states have provisions on private well water safety and quality. At the same time, a few counties within states have regulations overseeing private well inspections. The water in private wells originates from rainfall that is absorbed into the ground. Where it is caught in pores and spaces. Otherwise called spring or aquifer, this is “groundwater” that is gotten to by wells. In case that groundwater gets polluted from contaminants during overflow or through leakage, it can bring about sickness whenever ingested. Likely sources of contamination contain naturally occurring conditions. Additionally, human activities range from minerals and metals that drain from the soil, such as arsenic, iron, and manganese, to spillage from landfills, leaking septic tanks and pesticides. Testing well water is a generally basic process. An accredited laboratory investigates sample water from the well. This could be the state or local public health laboratory. The laboratory gives test kits. It can either be dropped off at the research center or sent by for overnight delivery. The testing expense differs, depending upon the research center doing the testing and the number and kind of tests directed.
Kinds of Contamination
Major health-related outcomes can result from contaminated water. These involve gastrointestinal disease from bacteria, viruses, parasites, heavy metal poisoning from lead, arsenic, and different metals or poisoning from fertilizer or synthetic compounds.
Microorganisms (e.g., bacteria, viruses, and parasites)
Nitrate and nitrites
Heavy metals (e.g., arsenic, antimony, cadmium, chromium, copper, lead, selenium, and others)
Radionuclides (i.e., radioactive forms of elements such as uranium and radium)
Degree of Contamination
The latest national survey of private wells’ quality was done in 2009 by the US Geological Survey (USGS). It tested private wells in 48 states. Found that about 23% of the wells had at least one contaminant at a degree of likely health concern. Findings included:
- The contaminants frequently found at these elevated concentrations were inorganic chemicals. These are metals, radionuclides, and nitrate; these, however, nitrate are gotten fundamentally from natural sources.
- Like pesticides and solvents, artificial organic compounds were found in the greater part (60%) of the domestic wells inspected. Yet concentrations were rarely more noteworthy than human-health standards (under 1% of wells).
- About half of the wells had at least one “nuisance” contaminant; this is a compound that harms taste, smell, or other stylish factors—at a level or concentrations outside the scope of qualities suggested by the US Environmental Protection Agency.
- Microbial contaminants such as bacteria were found in around 33% of the roughly 400 wells that had their water dissected for those contaminants.
- Contaminants detected in domestic wells, for the most part, co-happened with different contaminants as mixtures, instead of alone. This is a prospective concern because the total toxicity can be greater than that of any single contaminant.
Regulations of State and Local
There are no federal regulations on private wells. However, federal agencies give proposals and broad specialized guidelines. Regulation is additionally restricted at the state and local levels. A small number of states have guidelines on private well testing. A portion of these provisions applies to landlords or wells serving numerous units.
Counties regularly have provisions in building standards and allowing measures. One model is New Jersey’s Private Well Testing Act. Passed in 2001, it requires dealers or purchasers of a property with wells to test the untreated water for a kind of water quality limit and survey the test results preceding the title’s closing. Under the law, landowners are needed to test the well water once every five years. And then give a copy of the results to each tenant. The law was amended in 2018 to incorporate extra contaminants resolved to have hindering health impacts.
A report by the New Jersey Department of Environment Protection gives insights concerning the law and its usage.
North Carolina General Statute 87-97 expects districts to have programs to allow, investigate, and test private wells. Wells must be tested for bacterial and chemical contaminants within 30 days of completion. Tests are acquired by the health office or laboratory staff. Connecticut additionally requires testing of recently built wells.
The Michigan Safe Drinking Water Act applies to private wells that serve more than 25 people. Michigan has arranged sampling guidelines for testing the presence of PFAS in private wells. Furthermore suggests well testing for arsenic.
Florida does not have well testing guidelines for single-family households or individual rental units, yet has prerequisites for wells that serve different rental units or business property, under either the state’s Limited Use Public Water System rule or the Florida Safe Drinking Water Act. The state’s Landlord/Tenant Law places an obligation on the landowners to keep up plumbing in great working condition. Some Florida areas have rules on testing new wells and repairs.
Duty of Public Laboratories
The duty of states—and public laboratories, is essentially centered around recommendations and instruction of well owners, alongside help to assist them in guaranteeing their drinking water quality. A 2017 survey by Private Well Class gives bits of knowledge into the state’s function and nearby local public health and environmental laboratories in private well testing. Divided into 37 state public health and environmental laboratories and local laboratory directors, the survey’s discoveries center around the ability and limit of public health and environmental laboratories.
• About 70% of state public health laboratories and 57% of local public health laboratories acknowledge private well water tests from the general population.
• Public health laboratories test a yearly median of roughly 4,000 (state) and 1,000 (local) private well tests. There was great unevenness in the number of tests led. One state laboratory center tested 50,000 samples also, another tried 20,000. A local laboratory announced leading 4,000 tests.
• Approximately 75-84% of local and state public health laboratories depend on service fees to help the private well testing program.
Keeping Wells From Contamination
Private well owners can find a way to maintain a strategic distance from well water contamination.
Location of the Well Site
Take Measures After a Flood
Various preventive approaches can be made to restrict the contamination of groundwater. The agricultural community can decrease the use of pesticides and fertilizers. In regions with hard winters, communities find a way to decrease the amount of salt on the roads as the groundwater consumes the chemicals. Rapidly containing and tending to chemical spills can diminish the contamination of groundwater.
Also, it is practical to secure a water purification system. Choose a water filter that does not require to be connected to your home plumbing system. A complete standalone system can be set up in less than 10 minutes without any tools. Above all, one that can remove hundreds of contaminants such as viruses, bacteria, cysts, parasites, pesticides, chlorine, fluoride, VOC’s and more especially from your well water.
