Water is, not surprisingly, a numbers game, particularly in the efforts to make it safe for the public. This study guide explains the mathematics necessary to sit for certification exams and is organized according to grade. Grade 1, for example, includes conversion problems, percent calculations, pressure problems and pumping calculations, while Grade 2 includes density calculations, flow rate problems, and more advanced calculations for wells. Grade 3 includes advanced filtration rates, backwash, corrosion, and ion exchange softening problems and Grade 4 includes problems on lime dosage, mixture problems and calculations for such chemical issues as bicarbonate, carbonate and hydroxide alkalinity. Each grade comes with a sample test and answers and the guide comes with bibliography and resource lists.
