Safe Home® DIY Bacteria in Water Test Kit – Results as Fast as 24 Hours – Detects 50 Different Species of Coliform Bacteria – EPA Lab Certified – Made in the USA – (2 Pack)

Alerted me to a coliform issue in my well without having to pay hundreds for a plumber or professional testing. This is an accurate and easy to use test kit. Fantastic!

Easy to use

Being a scientist by training, I always appreciate controls to ensure that the kit is working properly. This kit comes with all that is needed to check a water sample, but if the results are negative, the question arises if the results are truly negative or if the kit is not working properly (false negative). We had our water checked by an alternate source, so I am confident that the negative E. coli result is correct, but if I was using this kit as a stand alone product, I would trust the data more if there were some controls included in the kit to ensure that the kit is working as expected.

This is a good product. Their tech support is also good. I've gone through maybe 8 of these during our struggle to get our well bacteria back to zero and want to share some info that might help. What I discovered is that shocking your well and plumbing alone is not enough- you must be super careful when taking your water sample and choosing the faucet for testing.The faucet should be one of the old-fashioned two valve type, because those modern single handle styles use a cartridge that could allow bacteria to survive the shocking process. If you don't have any like that, then I've read that you can use an outside water hose faucet but I didn't try that.Next make sure the areator is off- that's a bacteria reservoir too.You are only testing the cold water, so make sure the hot is turned totally off.Next run the cold water to see if you get splashing back up from the basin- if you do, then your test could be ruined so figure out if you need to lay something down in the sink or maybe pull out the drain plug.Next thoroughly clean the faucet end with diluted chlorine or isopropyl alcohol (I used 100% isopropyl, but 70% should work if it's fresh). Use paper towels/cotton swab to really get into the threads and around the exterior too.Finally run the cold water for 5-10 minutes to get clean water to the tap and to rinse off any leftover disinfectant.I tested using the "just run water" method and got bright green positive bacteria within 24 hrs. I then retested with my method above and finally, thankfully, got negative coliforms.To anyone reading this, believe me, I feel your pain and wish you success!!

We did this home test immediately after returning to our house post hurricane Helene evacuation. Within 48 hours, it turned green indicating positive for bacteria. That same day we sent off our lab test... It also came back positive for bacteria though negative for E coli. I am really impressed that the home test worked, because the total bacteria level was only 9 CFU/mL. For reference, the EPA limit is 500 CFU/mL!

Clear, simple instructions. Hopefully the test is accurate.

Worked very well. Very accurate

Simple easy to understand instructions, water well is safe.
