There are six basic steps you can take to help protect your private drinking water supply:
- Identify potential problem sources.
- Talk with local experts.
- Have your water tested periodically.
- Have the test results interpreted and explained clearly.
- Set and follow a regular maintenance schedule for your well, and keep up-to-date records.
- Immediately remedy any problems.
Identify Potential Problem Sources
Understanding and spotting possible pollution sources is the first step to safeguarding your drinking water. If your drinking water comes from a well, you may also have a septic system. Septic systems and other on-site wastewater disposal systems are major potential sources of contamination of private water supplies if they are poorly maintained or located improperly, or if they are used for disposal of toxic chemicals. Information on septic systems is available from local health departments, state agencies, and the National Small Flows Clearinghouse. A septic system design manual and guidance on system maintenance are available from EPA (http://cfpub.epa.gov/owm/septic/index.cfm)
Talk With Local Experts
Ground water conditions vary greatly from place to place, and local experts can give you the best information about your drinking water supply. Some examples are your health department's "sanitarian," local water-well contractors, public water system officials, county extension agents of the Natural Resources Conservation Service (NRCS), local or county planning commissions, and your local library.
Have Your Water Tested Periodically
Test your water every year for total coliform bacteria, nitrates, total dissolved solids, and pH levels. If you suspect other contaminants, test for these as well. As the tests can be expensive, limit them to possible problems specific to your situation. Local experts can help you identify these contaminants. You should also test your water after replacing or repairing any part of the system, or if you notice any change in your water's look, taste, or smell.
Often, county health departments perform tests for bacteria and nitrates. For other substances, health departments, environmental offices, or county governments should have a list of state-certified laboratories. Your State Laboratory Certification Officer can also provide you with this list. Call the Safe Drinking Water Hotline for the name and number of your state's certification officer. Any laboratory you use should be certified to do drinking water testing.
Have Your Test Results Interpreted And Explained Clearly
Compare your well's test results to federal and state drinking water standards. You may need to consult experts to aid you in understanding your results, such as the state agency that licenses water well contractors, your local health department, or your state's drinking water program.
Set A Regular Maintenance Schedule For Your Well And Your Septic System
Proper well and septic system construction and continued maintenance are keys to the safety of your water supply. Your state water well and septic system contractor licensing agency, local health department, or local public water system professional can provide information on well construction. Make certain your contractors are licensed by the state, if required, or certified by the National Ground Water Association.
Maintain your well, fixing problems before they reach crisis levels, and keep up-to-date records of well installation and repairs, as well as plumbing and water costs. Protect your own well area from contamination.
Immediately Remedy Any Problems
If you find that your well water is contaminated, fix the problem as soon as possible. Consider connecting into a
nearby community water system, if one is available. You may want to install a water treatment device to remove impurities. If you connect to a public water system, remember to close your well properly.
After A Flood-Concerns And Advisories
- Stay away from well pump to avoid electric shock.
- Do not drink or wash from a flooded well.
- Pump the well until water runs clear.
- If water does not run clear, contact the county or state health department or extension service for advice.
