Well Testing

People who live within city limits are on public water systems which are regulated by the Safe Drinking Water Act, and therefore that water is tested on a regular basis and information is available to the public. Private well owners do not benefit from this and therefore are responsible for their own water quality.  It is important to test your well annually to make sure there are no harmful bacteria or other chemicals present in your drinking water.  Your first step should be to contact the Conservation District or a certified testing lab, and you should always test for bacteria and nitrates.  Every five years or so you may want to broaden your sampling by testing pH, dissolved solids, alkalinity, & a variety of other parameters (selenium, uranium, arsenic, pesticides, and VOC’s ).  Testing should always be conducted if you ever notice a change in your water.  Ideally you will want to test 20160304_113738-1-1your well in the morning on a Monday and deliver or mail the samples to the lab on the same day because the bacteria in the samples are only good for a little over a day and you will get your results by the end of the week.  You will also want to collect the water for the sampling from a faucet that has both hot and cold settings, remove any type of treatment device and the aeration device.  Wash your hands and sanitize the mouth of the faucet, then let it flush for a few minutes to avoid any contamination.  

Steps to Protect Your Well

It is important to make sure your well is protected from infestations of insects and the chance for vermin to enter into your wellhead and become trapped; a sanitary seal (vs. a cap) is your best option and check your conduit to ensure a good seal, as they settle over time.  You also want to make sure you do not have large manure piles next to your well heads or places that require herbicide applications, as leaching will contaminate your drinking water and potentially the ground water which supplies you and your neighbors. Ideally the ground around your well head should appear as a mound and slope away from the wellhead, this is ideal to keep all hazardous contaminants out of your water.  It is important to regularly check the pit to ensure the wiring, adapters, and plumbing are not damaged, properly insulated, and nothing is being stored within the vicinity.  It is also important to keep records of maintenance for your well and septic system.

How We Can Help 

The Conservation District works with the Water Quality Protection District as well as the Well Educated Program to get the community engaged with well testing and to be able to provide better information about the ground water in the Helena Valley.  Test Kits are free and you can obtain them from our office and we cover a portion of the well testing cost.  Please stop by today to obtain and inquire about a well testing kit and what steps you can take to test and regulate your well.

In addition, the Conservation District runs a cost share program every year, assisting landowners with well testing costs.  Submit your water test results from Lewis and Clark County to the Conservation District via email or mail and we’ll reimburse $25 per test.
