How to take a Water Well Sample

Sampling Information
1. Take sample from a faucet without soft water or an aerator. If faucet has an aerator, remove before taking sample. Outside faucets are not usually soft water, and they are the best place to take water samples.
2. Flame the faucet with a lighter or wipe with a cloth and bleach.
3. Allow water to run about five minutes with a full stream of water.
4. Turn faucet to slow water to a pencil sized stream so it doesn’t spray.
5. Remove bottle cap without touching threads or inside of cap or bottle.
6. Fill bottle without running over. Carefully replace cap and tighten securely, then shut water off.
7. Complete the form attached to each bottle
8. If taking a sample for lead, take sample immediately in the morning before using water. Then follow steps 1-7 mentioned-above.

Sample Bottles and Testing
1. Bottles for well samples are available at the Health Department office, right across from the new LaGrange Parkview Hospital.

Private Water Well Testing Report for Food Operation

Food service operation permit holders in Lagrange County with private water supply will have to show proof of your water test before a new permit will be issued for the following year.

Nitrite: Every 5 years
Nitrate: One per year

Bottled Water

Visit the FDA website for information on the different types of waters. Read the label on your bottled water. This label can tell you about the way the bottled water is treated. Check the label for an 800-number or web address of the company that bottled the water. This may be a place to get further information. For more information on bottled water, visit the International Bottled Water Association (IBWA), which represents many of the U.S. water bottlers.

Residential Water Well

The LaGrange County Health Department has free sample bottles to test drinking water wells. The bottles are available during our regular business hours and may be brought back only on Tuesdays before noon.

The water samples are commonly tested for bacteria and nitrates. Each sample needs to be in a separate bottle. The testing fee is $20 for bacteria, $25 for nitrate, and $7 for courier service to the Hoosier Microbiology Laboratory (total cost is $27 for bacteria only, $32 for nitrate only or $52 for both bacteria and nitrates).

General Information:

LaGrange County has no water well ordinances. It is recommended to test private water supplies (“wells”) annually for nitrate and coliform bacteria. If any of these tests are over the maximum contaminant level that are recommended for household water well; additional tests could be done to detect possible contamination problems.

Well Records

Water Well Record Database

Search the Water Well Database

The Water Rights and Use Section currently maintains, in original paper and digital form, the records of over 400,000 water wells drilled in Indiana. Of this number approximately 138,000 records have been field verified.

This online database is provided to help Indiana citizens, drillers, consultants, and others access these public records quickly and easily. There are several search options available. However, due to the size and complexity of the database, we are unable to offer the water well owner’s name as search criteria. A street address and zip code search is available through either of the water well viewers below. It is recommended that first time users of this online database familiarize themselves with the About this Service and Database Search pages.
