1) For the water quality analyses shown below, make a bar chart of the ions in the water (using units of mg/L as CaCO3) and label total hardness (TH), carbonate

hardness (CH) and non-carbonate hardness(NCH), if applicable. Determine if all the ions in the water have been measured (i.e., is there a charge balance (within 5%)?). Assume the iron (Fe) is all present as Fe2+.
