Total Dissolved Solids, or conductivity, is commonly measured with a meter. The shortcoming of meters is that they need calibration. Our Waterworks TDS strips are factory calibrated and inexpensive. Just dip and match the color to determine the TDS level in your tap water. The US EPA Secondary Drinking Water Standard is 500ppm for TDS.

Total Dissolved Solids: High concentrations of total dissolved solids (TDS) may cause adverse taste effects. Highly mineralized water may also deteriorate domestic plumbing and appliances. It is recommended that waters containing more than 500 mg/L of dissolved solids not be used if other less mineralized supplies are available. This does not mean water containing more than 500 mg/L TDS is unusable.
