This information is obtained through laboratory analysis. Because the mineral levels can shift seasonally or even day-to-day, it is recommended to monitor the overall minerality via [[TDS testing]], and it may be necessary to obtain a new analysis periodically. Analysis should ideally also be carried out over at least a one-year period to determine seasonal fluctuations.<ref name=eumbam>Eumann M.

'''Ward Labs''' | '''Ward Labs''' provides a [https://www.wardlab.com/brewers-water-test-kit/ Brewer’s Test "kit"] that includes a return label and prepaid postage, sample information sheet, clean bottle for sample, and packaging material. Once the lab receives your water sample, you get a report with the values for sodium, calcium, magnesium, potassium, carbonate, bicarbonate, chloride, iron, sulfate, nitrate, electrical conductivity, total dissolved solids, pH, total hardness, total alkalinity, and total phosphorus.<ref>[https://www.wardlab.com/brewers-water-test-kit/ Brewer’s / water test kit.] Ward Laboratories website.
