  6. Water Quality • Based on

  7. Water Analysis • Sulfate • Nitrate • Fluoride

  8. Water Analysis (cont.) • pH • Iron and Manganese • Sodium • Calcium Carbonate

  9. Calcium Carbonate • Calcium Carbonate • Desirable <200 ppm • 100 ppm: – soft water • 100 – 200 ppm: reasonably soft • 200 – 300 ppm: avg hardness • 300 – 400 ppm: very hard • Over 400 ppm: extremely hard • Too hard
