Everyone should have their water tested for bacteria, nitrate, and lead when they move to a house with a private well, and at least every few years after that. Although other contaminants have the potential to contaminate your ground water as well, bacteria, nitrate, and lead are the most common and can be tested for a reasonable cost. Testing for those three ranges from a few dollars up to $30 or so (each parameter) in some labs, while testing for pesticides is likely to cost more. If you are on a public water system ("city water"), the water system is required to test the water regularly. Unless you have a reason to suspect contamination, or live in an older home and suspect lead from your house’s piping may be contaminating the water, you should not need to test the water yourself.
The Indiana State
of Health Laboratory (ISDH) will test private well water samples
for the following parameters, The cost is $10 for bacteria, fluoride, or nitrate, and $20 for the lead, copper, and arsenic test, plus $6.50 shipping and handling.
To find Indiana laboratories that test for other contaminants, the most up-to-date source of information is maintained by the Indiana State Department of Health. At this web site, select "certified chemistry laboratories" to find labs that test for parameters such as copper, lead, mercury, nitrate, fluoride, pesticides and other synthetic organic chemicals, or volatile organic chemicals. Select "certified microbiology labs" to find labs that test for E. coli or other bacteria.
have collaborated in the past with Heidelberg
College Water Quality Labs (now called the National Center for Water Quality Research) to test private wells in Indiana for
pesticides, metals, nitrates, and other contaminants. Prices are listed at the bottom of this web page. You may wish to
