Pool and hot tubs are wonderful for recreational activity, aerobic activity and physical therapy, relaxation, and social gatherings. However, they may not be so wonderful for your local freshwater. Pool and hot tub water that is improperly discharged or improperly treated before being released can end up in different water bodies, negatively affecting the water quality and therefore the different aquatic organisms and vegetation that live there.
