 Clarenda Park and Recreation Director Carson Riedel says he sympathizes with the Shenandoah Pool's plight. Riedel says keeping a pool operating, especially a year-round facility, is a massive undertaking. The number of chemicals and things that we have to purchase regularly in order to keep it at the standard that's required by organizations around the nation. In addition to those costs, we have repair costs, you know, things break down. I mean, when you're running chemicals through tubing and machine parts, they wear out.
