can this be used for soil testing?

Hello. The 481396-5 Arsenic Quick Test Kit contains enough testing materials to perform 5 tests on water samples, soil samples or wood samples. Each kit comes with a instruction manual that includes directions for testing water samples, soil samples and wood samples. We hope this helps! - Water Test Kit Store

At step 2, our water is yellow, but if we wait longer than 2 min it clears. Should we wait for step 3 after it clears?

Color of the water is irrelevant. Conduct the test as the directions tell you. The test strip hangs above the water.

I followed all directions and can’t get it to work.

Hello, I am unable to help you without details. This test is very time sensitive and if too much time has passed before proceeding to the next step or before taking readings, you will not get results. You may also not have detectable levels (for this particular kit) in your water. You may need the low range or ultra low range test kit. Please contact the vendor you purchased it from directly or the manufacturer with complete details to help troubleshoot. Thank you!
