Laid black (double dye) tanbark and then it rained three inches. It seeped into my well water, and now I have black tinted water. I have been running the water and I am going to clean out the water softener and flush out the water heater. Should I still get the water tested? I do have a uv light for bacteria. I don't know where my well is, so I can't do anything there. Any advice? Did get a few tips on flushing out gas water heater, but one said turn down the temp and another says to turn off. Confused!
