Well Water Testing Frequently Asked Questions Download PDF version formatted for print (137 KB/3 pages) Should I have my well tested? Yes. In 1999 - 2000, contaminated private well water caused 26% of the drinking water outbreaks that made people sick. The U.S. Environmental Protection Agency's (EPA) rules that protect public drinking water systems do not apply to privately owned wells. Most states have rules for private wells, but these rules may not completely protect your private well. In other words, as a private well owner, it is up to you to make sure that your well water is safe to drink. Your local health or environmental department can help advise you. When should I have my well tested? Check your well every spring to make sure there are no mechanical problems; test it once each year for germs and once every two to three years for harmful chemicals. You should also have your well tested if: There are known problems with well water in your area You have experienced problems near your well (i.e., flooding, land disturbances, and nearby waste disposal sites) You replace or repair any part of your well system. How do I find out if my well is contaminated? The only way to find out if your well water is contaminated is to test it. You can contact your health or environmental department, or a private laboratory to test for germs and harmful chemicals. In some states, the drilling contractor must test a new well after it is built. However, as a well owner, it is up to you to maintain your well and have it tested regularly. How do germs and chemicals get into my well water? Germs and chemicals can get into your well water and contaminate it in different ways. Some germs and chemicals occur naturally. For example, heavy metals like arsenic, lead, and cadmium are naturally found in rocks and soil and sometimes seep into ground water. Other contaminants come from human and animal waste resulting from polluted storm water runoff, agricultural runoff, flooded sewers, or individual septic systems that are not working properly. What are the germs and chemicals I should test for in my well? Several things you should test for are listed below. These germs and chemicals can be a risk to your health. (Please see the Contaminants in Well Water fact sheet for a list of common germs and chemicals in drinking water and the illnesses they cause.) Total Coliform Coliform bacteria are microbes found in the digestive systems of warm-blooded animals, in soil, on plants, and in surface water. These microbes typically do not make you sick; however, because microbes that do cause disease are hard to test for in the water, "total coliforms" are tested instead. If the total coliform count is high, then it is very possible that harmful germs like viruses, bacteria, and parasites might also be found in the water. Fecal Coliform / Escherichia coli (E. coli) Fecal coliform bacteria are a kind of total coliform. The feces (or stool) and digestive systems of humans and warm-blooded animals contain millions of fecal coliforms. E. coli is part of the fecal coliform group and may be tested for by itself. Fecal coliforms and E. coli are usually harmless. However, a positive test may mean that feces and harmful germs have found their way into your water system. These harmful germs can cause diarrhea, dysentery, and hepatitis. It is important not to confuse the test for the common and usually harmless E. coli with a test for the more dangerous E. coli O157:H7. Nitrate Nitrate is naturally found in many types of food. However, high levels of nitrate in drinking water can make people sick. Nitrate in your well water can come from animal waste, private septic systems, wastewater, flooded sewers, polluted storm water runoff, fertilizers, agricultural runoff, and decaying plants. The presence of nitrate in well water also depends on the geology of the land around your well. A nitrate test is recommended for all wells. If the nitrate level in your water is higher than the EPA standards, you should look for other sources of water or ways to treat your water. Volatile Organic Compounds (VOCs) VOCs are industrial and fuel-related chemicals that may cause bad health effects at certain levels. Which VOCs to test for depends on where you live. Contact your local health or environmental department, or the EPA to find out if any VOCs are a problem in your region. Some VOCs to ask about testing for are benzene, carbon tetrachloride, toluene, trichloroethelene, and methyl tertiary butyl ether (MTBE). pH The pH level tells you how acidic or basic your water is. The pH level of the water can change how your water looks and tastes. If the pH of your water is too low or too high, it could damage your pipes, cause heavy metals like lead to leak out of the pipes into the water, and eventually make you sick. Other germs or harmful chemicals that you should test for will depend on where your well is located on your property, which state you live in, and whether you live in an urban or rural area. These tests could include testing for lead, arsenic, mercury, radium, atrazine, and other pesticides. You should check with your local health or environmental department, or the EPA to find out if any of these are a problem in your region. Please remember that if your test results say that there are germs or chemicals in your water, you should contact your local health or environmental department for help and test your water more often. My well water has a funny smell or taste; should I worry about getting sick? A change in your water's taste, color, or smell is often not a health concern. However, a change could be a sign of serious contamination problems. Any time you notice a change in your water quality, you should have it tested. Where do I go to have my well water tested? State and local health or environmental departments often test for bacteria and nitrates. Health or environmental departments, or county governments should have a list of the state-certified (licensed) laboratories in your area that test for a variety of substances. Others who may be able to provide you with this listing include: Your State Laboratory Certification Officer EPA's Safe Drinking Water Hotline: 1-800-426-4791 EPA's Web site

Home Inspection FAQ

WHAT IS A HOME INSPECTION ?

A home inspection is an objective visual examination of the physical structure and systems of a home, from the roof to the  foundation. Having a home inspected is like giving it a physical check-up. If problems or symptoms are found, the inspector may recommend further evaluation.

WHAT DOES IT INCLUDE ?

The standard home inspector's report will review the condition of the home's heating system, central air conditioning system (temperature permitting), interior plumbing and electrical systems; the roof, attic, and visible insulation; walls, ceilings, floors, windows and doors; the foundation, basement, and visible structure.

WHY DO I NEED A HOME INSPECTION ?

The purchase of a home is probably the largest single investment you will ever make. You should learn as much as you can about the condition of the property and the need for any major repairs before you buy, so that you can minimize unpleasant surprises and difficulties afterwards.

Of course, a home inspection also points out the positive aspects of a home, as well as the maintenance that will be necessary to keep it in good shape. After the inspection, you will have a much clearer understanding of the property you are about to purchase.

If you are already a home owner, a home inspection may be used to identify problems in the making and to learn preventive measures which might avoid costly future repairs. If you are planning to sell your home, you may wish to have an inspection prior to placing your home on the market. This will give you a better understanding of conditions which may be discovered by the buyer's inspector, and an opportunity to make repairs that will put the house in better selling condition.

WHAT WILL IT COST ?

The inspection fee for a typical one-family house varies geographically, as does the cost of housing. Similarly, within a given area, the inspection fee may vary depending upon the size of the house, particular features of the house, its age, and possible additional services, such as septic, well, or radon testing. It is a good idea to check local prices on your own.

However, do not let cost be a factor in deciding whether or not to have a home inspection, or in the selection of your home inspector. The knowledge gained from an inspection is well worth the cost, and the lowest-priced inspector is not necessarily a bargain. The inspector's qualifications, including his experience, training, and professional affiliations, should be the most important consideration.

CAN'T I DO IT MYSELF ?

Even the most experienced home owner lacks the knowledge and expertise of a professional home inspector who has inspected hundreds, perhaps thousands, of homes in his or her career. An inspector is familiar with the many elements of home construction, their proper installation, and maintenance. He or she understands how the home's systems and components are intended to function together, as well as how and why they fail.

Above all, most buyers find it very difficult to remain completely objective and unemotional about the house they really want, and this may affect their judgment. For the most accurate information, it is best to obtain an impartial third-party opinion by an expert in the field of home inspection.

CAN A HOUSE FAIL INSPECTION ?

No. A professional home inspection is an examination of the current condition of your prospective home. It is not an appraisal, which determines market value, or a municipal inspection, which verifies local code compliance. A home inspector, therefore, will not pass or fail a house, but rather describe its physical condition and indicate what may need repair or replacement.

HOW DO I FIND A HOME INSPECTOR ?

The best source is a friend, or perhaps a business acquaintance, who has been satisfied with and can recommend a home inspector they have used. In addition, the names of local inspectors can be found by searching our online database, or in the Yellow Pages where many advertise under "Building Inspection Service" or "Home Inspection Service". Real estate agents are also generally familiar with the service, and should be able to provide you with a list of names from which to choose.

Whatever your referral source, you will want to make sure that the home inspector is a Member of the American Society of Home Inspectors® (ASHI®) in order to be certain of his or her professional qualifications, experience, and business ethics. A list of ASHI® Members in your area is available upon request from the Association's headquarters.

WHAT IS THE AMERICAN SOCIETY OF HOME INSPECTORS ?

The American Society of Home Inspectors® (ASHI®) is the oldest and leading non-profit professional association for independent home inspectors. Since its formation in 1976, ASHI's "Standards of Practice" have served as the home inspector's performance guideline, universally recognized and accepted by professional and government authorities alike. Copies of the Standards are available free from ASHI.

ASHI's professional Code of Ethics prohibits Members from engaging in conflict of interest activities which might compromise their objectivity. This is the consumer's assurance that the inspector will not, for example, use the inspection to solicit or refer repair work.

In order to assist home inspectors in furthering their education, ASHI sponsors a number of technical seminars and workshops throughout the year, often in cooperation with one of its nearly 50 Chapters. ASHI also serves as a public interest group by providing accurate and helpful consumer information to home buyers on home purchasing and home maintenance.

WHO BELONGS TO ASHI ?

Members of ASHI® are independent professional home inspectors who have met the most rigorous technical and experience requirements in effect today. To become an ASHI Member, an inspector must pass two written technical exams, have performed a minimum of 250 professional fee-paid home inspections, and maintained his or her candidate status for no less than six months. ASHI Members are required to follow the Society's Code of Ethics, and to obtain continuing education credits in order to keep current with the latest in building technology, materials, and professional skills.

WHEN DO I CALL IN THE HOME INSPECTOR ?

A home inspector is typically contacted right after the contract or purchase agreement has been signed, and is often available within a few days. However, before you sign, be sure that there is an inspection clause in the contract, making your purchase obligation contingent upon the findings of a professional home inspection. This clause should specify the terms to which both the buyer and seller are obligated.

DO I HAVE TO BE THERE ?

It is not necessary for you to be present for the inspection, but it is recommended. You will be able to observe the inspector and ask questions directly, as you learn about the condition of the home, how its systems work, and how to maintain it. You will also find the written report easier to understand if you've seen the property first-hand through the inspector's eyes.

WHAT IF THE REPORT REVEALS PROBLEMS ?

No house is perfect. If the inspector identifies problems, it doesn't necessarily mean you shouldn't buy the house, only that you will know in advance what to expect. A seller may adjust the purchase price or contract terms if major problems are found. If your budget is tight, or if you don't wish to become involved in future repair work, this information will be extremely important to you.

IF THE HOUSE PROVES TO BE IN GOOD CONDITION, DID I REALLY NEED AN INSPECTION ?

Definitely. Now you can complete your home purchase with your eyes open as to the condition of the property and all its equipment and systems. You will also have learned many things about your new home from the inspector's written report, and will want to keep that information for future reference.
