A process for removing lead and copper from drinking water discharged from a drinking water outlet while suppressing the concentration of phosphate ions comprising directing the water through a matrix comprising phosphate mineral with a very low phosphate solubility, and a solid carbonate mineral which is slightly soluble in water. The matrix is sized such that there is sufficient contacting between the water and the matrix to form a lead phosphate precipitate, reduce the lead concentration in the water to below 15 parts per billion, and suppress the phosphate ion concentration to 5 mg/L, preferably 3 mg/L, or below.
