This month's “Certification Corner” presents problems on the following topics: calculating the solution‐strength by weight of a chemical dissolved in water; calculating filter backwash; identifying organisms frequently associated with tastes and odors in water supplies; determining the reason why backwash rate requirements are greater in summer than in winter; and identifying one compound used as a coagulating chemical in water treatment.
