 Well, ten and a half grains is considered extremely hard, according to the Water Quality Association. My goal is to get that watered less than one grain, and that is true soft water. But one thing, too, like I said, on our municipal water, yes, it has been treated. It has been cleaned. The nice thing is we're not dealing with a lot of iron in the water. That's been filtered out at the treatment plant. Like I said, the level one contaminants with the arsenic leads, that's not a concern.
