Safe Home® DIY Bacteria in Water Test Kit – Results as Fast as 6 Hours – Detects 50 Different Species of Coliform Bacteria – EPA Lab Certified – Made in the USA – (2 Pack)

The Safe Home DIY Bacteria in Water Test Kit is an excellent option for anyone wanting a quick and reliable way to check their water for coliform bacteria. The instructions were clear and easy to follow, and the kit felt well-made and professional. I appreciated that it provides results in as little as 24 hours, which is perfect when you need answers quickly. The fact that it’s EPA lab-certified and made in the USA gave me extra confidence in the accuracy. I used it to test both tap and filtered water, and everything came back clear—which gave me real peace of mind. The 2-pack is a nice bonus if you want to re-test or use on another source like well water. Highly recommend if you're looking for a straightforward, at-home water test that doesn’t require shipping samples out or waiting days for results.

This test kit performed beautifully! I rent my home, so I didn't want to spend alot of money to test through a lab...$60! The kit is very easy to use and the directions covered everything. Since my house is cooler the the 70 degree minimum temperature for testing, I figured my results might take more than 24 hours. Soon after the 24 hours, the water began to turn a bluish-green color. The color continued to deepen until there was no question. My water is contaminated by coliform bacteria. I took the sample container and the box to my landlord as proof, and it is now in his hands. $15 well spent!

If the results I got with this are true it's a good product.

Test was simple and gave us results in a short time. I was very satisfied with the product and recommend it highly. Price was reasonable.

Easy to use and did the job. First test showed Coliform bacteria at very end of the testing time…followed some advice online, removed the aerator from the faucet, and resampled the water. Tested all clear the second time. Saved me the trouble and expense of shocking my well.

October 22, 2025 Update I had a professional who works with the county health department come out and gather a water sample. He called today to confirm that we did indeed have bacteria in our water, so the test from Safe Home for bacteria did work. The test from Safe Home told us we had bacteria in the water, and the county health department took it one step farther and identified the specific type of bacteria, which was total coliform. Original Review: The test confirmed the presence of bacteria in our well water. I will check it against a professionally completed one by our county next month because of the positive result of bacteria in our water. It is easy to use, but it's important to follow directions to get it right. They tell you not to overfill the bottle with your water sample. My recommendation is to use a very slow flow of water from the faucet and keep checking the water level. If it seems to still be yellow after 24-48 hours, shake it to be sure it's still yellow. At first showed a yellow color that seemed to mean it lacked bacteria, but after 2 days I shook it and it turned green. They do suggest shaking it. The test can be completed quickly. I made sure I cleaned the faucet carefully with Chlorox, ran the water for the recommended amount of time, and had clean hands to be sure I didn't add any bacteria to the test. The test is fairly inexpensive and seems to be a good value for the money. I'm sure the professional test will cost me more, but it will be interesting to see how this test compares with the professional test. The main difference I can think of with regard to this test and the professional test I will get is that this test doesn't break down what bacteria is actually in the water. I just shows a blue or green color that suggests there is the presence of bacteria.

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!!

Trust. The advertisement send to be misleading. The pictures tall of de texting 50 bacteria. The fine print is 50 bacteria, but only if the chloroform family - ecoli. They say results in as little as 24 hours. If the test is negative, you have to leave for an additional 48 hours. (Total 72.) AND THEY DAY NOTHING ABOUT THE TEMPERATURE. THIS IS NOT A TEST PER SE, BUT A CULTIVATION OF YOUR WATER. I'M THE FINE PRINT, OPTIMUM TEMPERATURE IS 95.5⁰! So this this why the wild swing from 24 hours to 72 hours for a result. I find the warmest place in my home to leave the samples. They stayed the light yellow color - negative - and no shade of green or blue - positive. I bought these as I have continued red rings that grow from clean water in both toilets. Again. My "test" culture growth results were apparently negative from the 2 sinks in my home. But because of the marketing jargon, I'm left with an uneasy feeling to trust the results. Science likes honesty. I hope my $41 pack of 4 tests were worth it. They appear to have worked. But I still have these red rings I have to do more Google work to find out about.
