The following table shows the water analysis for a surface water sample. Based on the table, determine: $(40$ points$)$

a$)$ The calcium and magnesium concentrations in units of $me\frac{q}{L}$ and $m\frac{g}{L}$ as $CaC{O}_3.$

b$)$ Determine the hydronium $(H^{+})$and hydroxyl $(O{H}^{-})$ion concentrations in moles$/$L$.$

c$)$ Are there any constituents exceeding the MCL values according to the National Primary Drinking Water Regulations?

d$)$ Determine the alkalinity as $me\frac{q}{L}$ and as $m\frac{g}{L}$ equivalent $CaC{O}_3.$
