Wouldn't this test also give us a decent indication on the bacterial status of well water?

The detection level is 1000 CFU/ml and does not meet drinking water standards. For testing your well water, we would suggest using our well water test kit (product number: WS-425W). The WS-425W detects coliform bacteria and meets drinking water standards.

Could you use this to test rivers/ponds/creeks?

As the other people mentioned, this product will detect any bacteria and is very sensitive. Natural ecosystems should have bacteria in them so this is probably not a good option for streams, ponds, etc. to determine if there are contaminating bacteria, or pathogenic bacteria in a natural ecosystem, you will need a bacterial detection system that discriminates bacteria by type.

My city dumped sewage into our lake. Would this also work to test lake water for bacteria?

Dear Eddie, I think the best bet would be to go to http://www.silverlakeresearch.com/ , the website for the company, or call them at 626.359.8441. They make many products for testing water, including your tap water. I've read the more extensive instructions inside the packet, and it just doesn't specify using it on anything other than pools and spas and I don't know enough about the difference between testing chlorinated water and fresh water. Good luck with your water. Terrible thing for a city to do.

Can this test be used to test the water in a salt water pool as well?

Yes salt water has no way of letting you know its not safe unless you test with a test kit.

Not reliable

Not reliable product. Ran 2 tests that showed positive for bacteria in hot tub. Emptied, sanitized and thoroughly rinsed tub. Ran another test and got same result. Expensive unreliable product

Not sure if it really works

I liked the product when texting my pool water it came up negative within the first 10-15 min. But when I left it longer then that. It eventually turned positive. So don’t know which results to believe.

Directions not in box

Need to have directions in the box. Should not need a smart phone to do test. Thanks

Not too bad

One of the tube for collecting the water sample had. Agile in it making that whole test strip unusable. I have used four plus that one, not sure if any other test modules will have. A hole in the tube or not but not worth the return process. Just beware that out of the 10, you’ll have at least seven good ones maybe.
