Eric Roy, Ph.D.| Scientific Founder Updated on February 5, 2020 We get quite a few questions about TDS/ppm meters (like this one) and TDS measurements. While we love when people take steps to learn more about their water, some people (including journalists from reputable publications- Example #1 & Example #2) have used TDS/ppm meters to draw false conclusions about water quality, which

In areas with high concentration of minerals, the natural tap water could however be considerably higher. If a water sample contains less than 100 ppm, it is generally considered to have a low TDS content. However, the classification of TDS levels depends on the context and the nature of the dissolved solids. If the water contains beneficial minerals, 150-250 ppm can be an excellent TDS range for optimal health.

Most New Mexico cities have a hardness ranging from 150 to 300 PPM, such as Farmington, which has a water hardness level of 257 PPM. Roswell has extremely hard water with 410 Parts Per Million. PPM stands for parts per million. The only way to really make the ppm go down is a filter. Even brita style filters don't really do a whole lot.

damn myself for not doing this sooner. Percent to ppm converter How to convert ppm to percent. 1% = 1/100. 1ppm = 1/1000000.
