Question: does chlorinated wading pool water harm trees, if it's used to water them during a drought?

"One reason chlorinated water has little effect is that the chemical binds to soil-particle surfaces. This means that chlorine may kill off microorganisms in the upper few inches of soil, but lower levels of soil are not affected. While the water seeps on down, the chlorine does not. Even heavily chlorinated water -- 5 parts per million -- impacts microorganisms in only the top half inch of soil, according to a Colorado State University Extension article.
