You have been hired by the City of Far Far Away Utilities Department for a summer internship program. The city's water treatment plant uses groundwater to produce 1 million gallon water per day (MGD) for its inhabitants. The plant manager has asked you to procure chemicals for the lime-soda softening process. The groundwater was analyzed as follows: CO₂ = 80 mg/L as CaCO3 Ca2+ = 250 mg/L as CaCO3 Mg2+ = 247 mg/L as CaCO3 Na 76 mg/L as CaCO3 SO4 197 mg/L as CaCO3 = CI 76 mg/L as CaCO3 = Alkalinity 300 mg/L as CaCO3 pH = 7.0 (Equivalent weights (in mg/meq): CO₂ = 22, Ca²+ = 20, Mg2+ = 12.15, Na* = 23, HCO3 = 61, CI= 35.5, SO4² = 48) Complete the bar chart for the above water (chose the correct answer from below)
