TDS stands for “Total Dissolved Solids,” a measurement of the various minerals, organic, and non-organic matter present in water. PPM refers to “Parts Per Million.” Since these solids are microscopic, a single sip can contain hundreds of thousands of molecules. That said, a 50 PPM of TS is perfectly drinkable.

For example, say you have a water hardness value of 180 ppm. The same solvents are used for 13 C NMR spectra, so the same rules about splitting patterns apply here also. It used to be common practice to add Me 4 Si, or related compounds, as an internal reference standard for 1 H and 13 C NMR spectra with the proton signal occurring at 0.0 ppm and the carbon signal occurring at 0.0 ppm in the 13 C NMR spectrum.

If your water has nitrate levels above 10 mg/L, you should switch to bottled water or another source of safe drinking water and seek treatment options. Interpreting your nitrate results Nitrate results Water use Recommendation 10 ppm (mg/L) or less SAFE for all uses. Concentrations above 4 ppm may indicate contamination. Test water at least Soft water of 10-15 ppm can be produced by this method2.
