Private Well Program

Is your well water safe to drink?

Here are some questions for you. Do you test your private well water? If so, do you test it at least once each year? If not, how long has it been since you last tested your private water supply? When your water experiences changes in the way it looks, smells or tastes, do you have a water test performed?

In general, many of Iowa's aquifers will provide safe and plentiful drinking water for your rural home or farm. Keeping that in mind, did you know that not every aquifer provides safe drinking water, or that well construction varies with the age of well and the well contractor used?

This means that not all wells are constructed equally or access the same quality of water as other nearby wells. Changes in well design, construction, and depth, can make a difference in well water quality.

The only way to know if your water supply is safe is to have the water tested. Any given year, less than 7 percent of Iowa's private well owners test their water supply. Within this group, many don't test their wells regularly.

The Iowa DNR and many public health agencies recommend that you test your private water supply at least once each year, and anytime you notice water quality changes - things like water color, clarity, taste, smell, or sediment.

When you test your well water, keep in mind that the contaminants you should test for can vary depending on the well depth, the type of construction and age of the well, and the well's location. Sometimes testing for the basics - bacteria, nitrate, and arsenic - may not be enough. You can contact your local county environmental health department or a drinking water testing laboratory to inquire about well water testing that may be needed based on your location and concerns.

This website has guidance available to help you understand the importance of sampling and testing your private water system. Check out our Frequently Asked Questions About Private Drinking Water web page. To learn how you can qualify for free basic water testing, please contact your local county environmental health office and ask to participate in the Grants to Counties Well Testing Program.

Basic Information About the Occurrence of Lead in Private Drinking Water Supplies - Important Information You Should Know

Is lead in my drinking water something I should worry about?
The majority of the risk for lead in private water systems comes from the plumbing components that make-up your water system. Some of the components may be made of materials that contain some lead. Under the right conditions, the lead in these items can leach into water contained inside the pipes. An important point to keep in mind is that many homes in our state were constructed before 1986, the year when lead standards were first established for plumbing components used inside homes and businesses.

Many brass components are used in homes and, depending on the brass used, may contain lead. In the past, lead-tin solder was also used to make connections in copper plumbing as part of an industry standard. The lead-free standards were revised twice since 1986, most recently effective in 2014, which require the amounts of lead in plumbing and fixtures be much lower than the previous standards.

Because of this, we recommend that all private drinking water supplies be tested for lead. The only way you will know if you should take action to protect yourself and your family from long term health effects associated with lead is to test your water supply.

Currently, the public drinking water program action level for lead contamination in drinking water is when the testing indicates a level of 15 parts per billion or more. The maximum contaminant goal for lead in drinking water is zero. For private water supplies, we recommend the same action level and goal to ensure that your water is safe. Keep in mind that the only way to know if your water supply is safe is to collect a sample of your water and submit it to a drinking water lab for analysis.

Sampling your water supply is something that you can do yourself, or you can contact your local county environmental health department and ask for assistance. A list of local county contacts can be found at: https://www.iowadnr.gov/Portals/idnr/uploads/water/wells/co_sanitarians.pdf.

Water sample test kits are available through The State Hygienic Laboratory (SHL) or your local drinking water laboratory. To obtain a sample kit from SHL you can call 800-421-4692. A list of other drinking water laboratories can be found at: http://www.shl.uiowa.edu/labcert/idnr/index.xml. The typical sampling protocol is to use the water the night before the test as you normally would, then allow the water to sit in the pipes overnight. The sample is collected from the cold water tap in the kitchen or bathroom sink the first thing in the morning before any water has been used in the house.

How Does Lead Enter Drinking Water?
Lead is a toxic heavy metal that is harmful if inhaled or swallowed. It can be found in air, soil, dust, food, drinking water, and products such as lead-based paints. Lead typically enters drinking water through plumbing materials. All homes, regardless of their age, may have plumbing that contains lead. However, homes built before 1986 are more likely to have lead pipes, fixtures, and solder. Brass faucets, fittings, and valves, including those advertised as lead-free, may contribute lead to drinking water. The law currently allows pipes, fittings, and fixtures with up to 0.25 percent weighted average of lead to be identified as lead-free. Brass faucets and fittings and lead solder can leach lead into water, especially hot water.

What Are the Health Effects of Lead? Lead can cause serious health problems if too much enters the body from drinking water or other sources. Pregnant women, infants, and young children have the highest risks of negative health effects from lead exposure. Lead exposure in children under the age of six has been linked to damage to the central and peripheral nervous system, learning disabilities, shorter stature, impaired hearing, impaired formation and function of blood cells, and lowered IQ. Lead can accumulate in our bodies over time, where it is stored in bones along with calcium. During pregnancy, lead is released from bones as maternal calcium and is used to help form the bones of the fetus. This can result in serious effects to the mother and her developing fetus, including reduced growth of the fetus and premature birth. Adults exposed to lead could develop kidney problems or high blood pressure. Lead is stored in the bones and can be released later in life. If you are concerned about lead exposure, you may want to ask your health care provider about testing children to determine the levels of lead in their blood.

How Can I Reduce Exposure to Lead from Drinking Water?
There are several steps that you can take to reduce your and your family's exposure to lead from drinking water.

• Run your water to flush out lead. The longer water sits in your home piping; the more lead may leach from lead-containing fixtures. Before drinking, flush your pipes for several minutes by running your tap, taking a shower, doing laundry or a load of dishes.
• Use cold water to cook and to prepare baby formula. Do not cook with or drink water from the hot water tap; lead dissolves more easily into hot water. Do not use water from the hot water tap to make baby formula. Remember, boiling water DOES NOT remove lead from water.
• Identify and replace plumbing fixtures that contain lead. Brass faucets, fittings, and valves, including those advertised as “lead-free,” may contribute lead to drinking water. The law currently allows pipes, fittings, and fixtures with up to 0.25 percent weighted average of lead to be identified as “lead-free”. Plumbing materials that are lead free can also be identified by looking for lead-free certification marks.
• Consider using a filter certified for lead removal. Read the package to be sure the filter is approved to reduce lead. Verify the claims of manufacturers by checking with independent certifying organizations that provide lists of treatment devices that they have certified.
• Regularly clean faucet aerators. Aerators, the screens at the end of faucets, can collect debris. Rinse out collected materials to reduce debris accumulation.
• Use an alternative source. Until the concentration of lead in drinking water is mitigated, you should use a different source of drinking water (i.e., bottled water).

What Steps Should I take if Lead is Found in my Water System? 
For a system with a lead level above zero, but 15 ppb or less:

• Decide if you want to obtain all of your drinking water from a known safe source, or add water treatment to lower the lead level closer to the maximum contamination level goal of zero.
• Understand the corrosivity of your water and keep it as low as possible because corrosive water can cause lead to leach from plumbing materials that contain lead. Water treatment may be required to buffer the water and reduce the water’s corrosive nature.
• Test the water supply periodically to monitor lead levels in your home to ensure that the level is stable or declining. If the lead level increases, additional action is required on your part to protect your health. These steps may include water treatment or replacing the water you consume with water from a known safe, lead-free source.
• Determine what improvements can be made in your home’s plumbing that may result in lower lead levels.
• Test your water system after water treatment anytime you install a new well or change water treatment on an existing well.

OR

For a system with a lead level over 15 ppb:

• Use an alternative source for drinking water or provide point-of-use water treatment for the water tap location you can dedicate to supply all of the home’s drinking water – keeping in mind that the maximum contamination goal for your water is zero.
• Increase how often you sample. We suggest testing for lead every 6 months so that you can closely monitor the lead levels in your water system. 
• Educate yourself on lead exposure and health risks. You should understand health effects of lead, the sources of lead in drinking water, and actions you can take to reduce exposure to leads in drinking water.
• Reduce the corrosivity of the water in the system. Corrosive water can cause lead to leach from plumbing materials that contain lead.
• Consider replacing the home’s plumbing to remove all components that contain lead and replace them with new components labeled as "lead-free" or "low lead". This includes lead solder used to join pipes, brass faucets, brass fittings, and brass valves that may contain lead.

The Iowa DNR is proposing a new Protected Water Source Area for small portions of Des Moines and Lee Counties. The Area is needed because of local groundwater contamination classified as Royal Demolition Explosive or RDX.

Protected Water Source areas are described in rule within 567 Iowa Administrative Code Chapter 53. They are only proposed and created when there is a need to ensure the long-term availability of the water sources and to preserve public health and welfare.

A PDF that shows the proposed boundaries of the Protected Water Source Area can be found by clicking on the map near this text, or at the following link: Map of proposed Protected Water Source Area.

The Area is currently defined as follows:

In Des Moines County, T68N, R3W, the West ½ of Section 1, all of Section 2, the NE quarter of Section 3, and in T69N, R3W, the east ½ of Section 34, all of Section 35, and the west ½ of Section 36.

In Lee County, T68N R3W, All of Section 1 and all of Section 2.

Under the current proposal:

• Private water supply wells in The Area will no longer be permitted through local county environmental health departments - Iowa DNR will be the only permitting authority within the proposed area.
• Well water use must not cause movement of contamination or an increase in contaminant levels.
• The well construction standards must be approved by Iowa DNR prior to construction, and provide redundant protections of the deeper, currently protected aquifer(s).
• Additional water quality monitoring will be required to track water quality in the aquifers.

These steps are intended to help ensure that well installations will not expose well users to RDX contamination, and the deeper currently protected aquifers are not impacted by the contaminant due to improper well construction and unauthorized water use.

The United States Environmental Protection Agency (USEPA) has a fact sheet that discusses RDX contamination. The doucment can be viewed by clicking on the image on the right of this text or on the following link: EPA Technical Fact Sheet on RDX.

This notification area will be updated as rulemaking activities progress. You can use the contact information below to inquire about the Proposed Protected Water Source Area or to provide comments about this activity. Russ Tell, phone 515-725-0462, or by email at russell.tell@dnr.iowa.gov, or by US Postal Service mail addressed to Russ Tell, Iowa DNR Water Supply, 502 E. 9th Street, Des Moines, IA 50319.

Preliminary comments should be received by the Department by January 10, 2019. There will be additional opportunities for public comment as the proposed rule moves through the processes of rulemaking.

Rural properties that come up for sale commonly have one or more water wells located somewhere on the parcel. Many times, a well provides the only drinking water supply available for the property. Did you know that there's more to understanding the safety and reliability of the drinking water supply than taking a water sample and sending it to a testing lab?

The Private Well Class has web based training that will help you understand what you should look for when a property has one of more water supply wells. Videos are available for your convenience at the following You Tube video link: What Realtors need to know about homes with well water.

NEW - GP6 Well Siting Tool

The Iowa DNR recently developed an online GP6 Well Siting Tool to assist landowners, well contractors, and engineers.

The tool is useful for performing desk evaluations of well sites and help determine if the well location will likely require discharge management through GP6. It also helps define which locations likely cannot support well construction discharge due to close proximity of Outstanding Iowa Waters (OIWs).

As a user of this tool, you have access to map layers that will help you identify distances to surface waters and OIWs, locations of sinkholes, karst areas, land slope, and more. It also allows you to print the map you create to use as a resource.

The GP6 Well Siting Tool works with Google Chrome and Mozilla Firefox web browsers. Currently, it is not compatible with Internet Explorer. To open and use the GP6 Well Siting Tool, click on the following link: https://programs.iowadnr.gov/maps/gp6/.

NOTICE - General Permit #6 Renewal

The NPDES General Permit for Well Construction and Well Service Discharges (also known as GP6) will expire on February 28, 2020. Iowa DNR proposes to initiate rulemaking to renew the permit for a third 5 year term. The proposed GP6 is nearly identical to the current general permit except for some clarifications.

The permit renewal process includes asking for comments from individual stakeholders, stakeholder groups, and other interested citizens. The department held a stakeholder meeting in May to accept comments about the renewal of the permit, note changes in the permit conditions, and discuss the renewal process.

Additional information can be obtained on the renewal process by contacting Wendy Hieb by phone at 515-725-8405, by email at wendy.hieb@dnr.iowa.gov, or by US Postal Service to Wendy Hieb, Iowa Department of Natural Resources, 502 E. 9th Street, Des Moines, IA 50319.

You can view the current draft of GP6 by downloading the document at the link below.

The DNR has a guidance document available to help well contractors, irrigation equipment provides, and well owners understand the requirements of developing high capacity wells.

High capacity wells are wells that withdraw 500 gallons per minute or more from groundwater sources.

The installation of all high capacity wells require the collection and submission of specific information before a Water Allocation and Use permit can be issued and the well put into high capacity service. This is an important step in assuring you can use quantity of water you need.

This information includes a detailed inventory of nearby wells, a complete set of borehole cutting samples, a detailed well log from the test well or production well, and a well pump test to verify the characteristics of the well, like the well's maximum capacity, pumping and non-pumping water levels, and potential for well interference with nearby wells.

Depending on well location and aquifer used, the applicant may be required to conduct an extended pump test to better define the effects the proposed water withdrawal has on nearby wells. If this test isn't performed at the time the well is drilled, the well owner will need to hire a well contractor to perform this step.

The pump test must be long enough in duration to achieve a stabilized water level in the test well or production well, and in the required observation well(s). It can take up to 72 hours of continuous test pumping to achieve a stabilized water level. This is why it's important to plan ahead when a high capacity well is in your plans.

During the test pumping, water level measurements are taken from the production and observation well(s) at predetermined intervals and the information accurately documented on a pump test log. This helps determine how much influence the new high capacity well has on the aquifer and nearby wells. Additional details can be found in Iowa DNR Technical Bulletin 23.1.

All pump test information is used to help the well owner secure a Water Allocation and Use Permit. A Water Allocation and Use permit is issued to convey the legal right to pump and use 25,000 gallons or more of water a day for a beneficial purposes, like crop irrigation or industrial processes.

Typical examples of water use permit holders include, but are not limited to: public water supply systems, power plants, manufacturing and processing industries, agricultural businesses, irrigation users (crop/agricultural, golf courses, turf or truck farms, and athletic fields), rock and gravel quarry operations, construction and temporary and permanent dewatering operations, recreational water uses and heating and/or cooling systems.

A Water Use Permit is required for any person or entity that withdraws 25,000 gallons or more of water in a 24-hour period. The permit lists the amount of water that can be withdrawn each year by the permittee and is valid for up to 10 years. A Water Use Permit also requires that a Water Use Report be submitted to the Iowa DNR each year.

To find out more about Water Use Permits or to apply for yours today, please refer to the Water Supply Engineering Water Allocation and Use website.

The Illinois State Water Survey and the Illinois Water Resources Center at the University of Illinois are pleased to announce a new nationwide training initiative funded by the Rural Community Assistance Partnership (RCAP) through a grant from the U.S. Environmental Protection Agency.

The training will includes classes for those who own or use private water supply wells, and individuals who are just curious about how wells function.

The Private Well Classes are designed to help you understand the basic science of water wells and inform them of best practices to maintain and protect the water supply. These basic tools can help you make informed decisions regarding your water supply. This helps ensure a safe drinking water supply and extend the life of the well.

The classes are part of an online learning experience that includes monthly emails with class lessons that are reinforced by monthly webinars you can - AND - you can attend as often as you wish, even after the emailed class materials have ended. Click here to find out how the class works.

The course include a Resource Library and Multimedia Learning area to provide specific learning tools. http://privatewellclass.org/library or http://privatewellclass.org/multimedia

Flood Awareness is Important!

Private water well users in or near flooded areas - keep in mind that consuming contaminated water can cause illness.

Extremely heavy rains have fallen in many locations across Iowa over the summer and now into the fall. In many cases the rain causes regional flooding of streams, rivers, and normally dry low-lying areas.

Floods can cause water quality problems with water supply wells - even if your well isn't directly in the flooded area. During a flood, there is an increased risk that drinking water wells may become contaminated with bacteria, viruses, and other contaminants that are commonly found in flood water.

Consuming contaminated water can cause serious illness - especially in infants, individuals with compromised immune systems, and our elderly population. Water testing is the only way to know if your well is affected. Please see our document named "What should I do when my well floods" for additional information.

Water System Council wellcare® information series also offers the following guidance for wells that may be affected by flooding:

Fact Sheets titled:

• Managing a Flooded Well,
• Emergencies, Disasters, and Wells, and
• Disinfecting Your Well.

And informative videos titled:

• Disinfecting a Well in Case of Contamination, and
• What Private Well Owners Need to Know About Your Water Supply in Case of a Natural Disaster.

The bottom line is if there is any doubt about the safety of your drinking water, you should use only bottled water or water from a known safe source until you can have your water supply sampled, tested at a drinking water laboratory, and proven safe.

To obtain more information on water testing, please contact your local county environmental health sanitarian, or view our water testing web page located at www.iowadnr.gov/privatewelltesting.

There are a number of areas in the state where it's not possible to install water supply wells or geothermal wells and boreholes. The most common reasons for this type of restriction is because of local groundwater contamination, or to provide water withdrawal protections in specific areas where an aquifer is experiencing high rates of groundwater withdrawal.

There are two methods used to manage drilling restrictions - Environmental Convenants (ECs) and Protected Water Source Areas (PWSAs). Either method essentially achieves the same result - limiting or restricting drilling or access to the groundwater.

Environmental Covenants (ECs) are the most common form of restriction and can be associated with many types of contamination. A few examples include Leaking Underground Storage Tanks - also known as LUST Sites, sites contaminated with industrial products or wastes, industrial landfills, and old dry cleaning facilities. Keep in mind that if multiple small areas of contamination are in close proximity to each other, the overall size of an EC can be quite large - up to and including an entire community.

ECs are developed through agreements with citizens or local governments. They are used when local drilling activities may cause movement of contaminants. The movement may be off-site into currently uncontaminated zones, movement of higher contaminant concentrations into an area that was known to be at a lower concentration, or vertically which can result in contamination of the local aquifers and nearby water supply wells.

If drilling activities cause problems with a contaminated site, it increases the liability for the owner of the site, the owner of the property where the drilling is taking place, and the well contractor performing the drilling.

The department maintains a list of the communities that have ECs. You can use this information to help identify areas where drilling may not be possible. The following link will open a PDF list of the current communities that maintain an Environmental Covenant.

Communities that restrict well drilling activities

Protected Water Source Areas (PWSAs) are developed when the protections needed are greater than can be provided by using an EC, or when the area of contamination is large. PWSAs are developed in state rules which provide for a higher level of management, tracking, and enforcement.

A list of current PWSAs can be found in 567 Iowa Administrative Code Chapter 53. 

The Iowa DNR Private Well Program provides regulatory oversight on a number of different types of vertical boreholes and borings that meet the legal definition of "well" in our state.

These well structures include:

• Private potable water supply wells like household and acreage wells. Basically, any water supply that is not regulated as a Public Water Supply.
• Private non-potable wells used on farm and in industry, like: Livestock wells, commercial water supply wells, manufacturing and processing water supply wells; cooling tower water supplies; and any other water well that supplies water for non-potable use.
• Irrigation wells for all uses including row crop irrigation, turf production, water for truck gardens and home yard irrigation.
• Temporary and permanent dewatering wells used to lower water tables to allow for subsurface construction or stabilization.
• Geothermal heat exchange water supply and reinjection wells used to exchange heat from a structure to the groundwater.
• Geothermal Heat Exchange (GHEX) closed loop boreholes used to exchange heat from a structure to the earth.
• Temporary and permanent test, observation and monitoring wells used to determine the quantity or quality of the groundwater or to monitor water groundwater levels.
• Temporary and permanent piezometer or monitoring wells used to look for contaminants in soils or groundwater.
• Direct push type technology for groundwater sampling when a temporary or permanent well casing and/or well screen is installed in the ground.

The Private Well Program rules only apply to water supply wells and systems that serve fewer than 25 individuals on a daily basis. If a water system serves water to 15 or more service connections (like campground spaces or condos) or serves at least 25 individuals, the system requires management under the public water supply rules.

Examples of smaller water systems that meet the definition of Public Water Supply definition includes but is not limited to:

• rural churches,
• rural restaurants, bars and entertainment venues,
• rural industrial or manufacturing facilities,
• rural trailer parks,
• rural wineries,
• rural conference or meeting halls,
• certain rural day care facilities,
• and any other place that is not connected to a municipal or rural water public water supply where the public gathers or conducts business and 25 or more individuals have access to the water.

Public Water Supplies have specific federal requirements to help protect the health of the water users and the integrity of the water system. These requirements address the design of the water well and water treatment systems as well as the storage and distribution systems. The design and construction of these facilities must follow approved specifications and standards as determined by the Iowa DNR Water Supply Engineering section. In addition, a Public Water Supply must manage and monitor the water system according to an operation permit issued by the Iowa DNR Water Supply Operations section. These steps help ensure that the water available and used by the public is safe for consumption. To find out if you are a Public Water Supply or for more information regarding Public Water Supply requirements, contact the IDNR Water Supply section at 515- 725-0282.

The Private Well Program provides administrative oversight of the statewide private well program. This includes rule development and interpretation, working cooperatively with local county governments to administer the private well program at a local level, working with well contractors regarding minimum and appropriate standards for well services, and providing guidance to private well owners and other citizens.

The goals of the Iowa DNR Private Well Program are to:

• Protect the groundwater resources and public health by establishing well construction, well maintenance and well plugging standards.
• Establish and maintain well contractor certification requirements for all types of boreholes that meet the definition of "well."
• Provide a source for accurate and meaningful guidance to help answer questions pertaining to the private well program areas.

The program goals are to have all wells constructed to appropriate minimum standards and that competent Iowa DNR Certified Well Contractors are on-site in direct control of each well service provided.

To help achieve the program goals the Private Well Program works with local county environmental health staff to issue private well construction permits at the local level. This relationship is an important part of the program and helps to ensure that there are local contacts to help local residents with permitting and construction information needs.

The Iowa DNR private well construction permit is issued by your local county on a web based private well permitting system known as the Private Well Tracking System or PWTS. This system electronically records well permit information as well as record and track well water testing reports, well renovation reports and well plugging reports.

The Private Well Program also works with the Iowa DNR Operator Certification Section to help Certified Well Contractors with their certification questions and testing, and helps training providers determine if a training event will qualify for continuing education units (CEUs) or "contact hours" for Iowa's well contractors.

You will find additional private well related topics in the left hand column or menu area of this web page. There are also useful links at the bottom of each web page for common private well topics. If you cannot find the information you are looking for, please contact us using the information at the bottom of this page.

The graph below provides the number of state private well construction permits issued each year in Iowa between 2002 through 2018. Both water supply wells (WW) and geothermal loop boreholes (GHEX) are shown. Click the graph to download a PDF version of the document.

You can take the following steps to help protect your water supply well and the groundwater used by you and others:

1. Maintain your well by inspecting, repairing, and replacing sanitary items as needed. This helps the well protect your water supply.
2. Limit your use of pesticides, fertilizers, or other chemicals that may impact the groundwater.
3. Store all farm chemicals in leak free closed containers, placed far from the well site. Apply all chemicals in strick adherance to the label directions, and never dispose of unneeded products onto the ground, or in storm sewers, sanitary sewers, or water ways.
4. Store all household chemicals away from the well and in leak-free containers. Apply all chemicals in strick adherance to the label directions, and never dispose of unneeded products onto the ground, or into storm sewers, sanitary sewers, or water ways.
5. Use backflow prevention devices on all hydrants and water spigots - especially if using to mix any type of contaminant.
6. Take used motor oil and antifreeze to a recycling center.
7. Be careful when you are doing any activity around the well so you don't damage the well cap, well wire conduit, well casing, or well vent. Even minor bumps can cause unseen damage that can affect well water quality.
8. Respect the resources you use. Conserve your water even if you don't have to, because water is a valuable resource and the cost of providing clean, safe water will only increase if we all don't do our part.
