I want to test ground water runoff from the Mass.Turnpike can i use the test kit for that and does anyone know what kind of reading is acceptable for that?
I have tasted the water and it tastes salty. thanks

Don't get me wrong I want to buy the kit for my pool testing, but I read that this years kit came with a salt test and I was just thinking outside the box. I know there are people on here who swear by the kit and was hoping someone could confirm usage. thanks
