Q: Two years ago there was construction going on nearby, and red clay was dumped into the lake I live on. Now, my neighbors, who use the lake water for irrigation have stains on their patios and houses and dead plants. I think the iron, from the dumped clay, is causing the staining. Can we treat the water to remove the iron?

A: I’m not an expert on this but members of the Georgia Lakes Society might be able to advise.
