DWS Well Water Test

Here is the list of at least 229 contaminants we explicitly test for in the DWS Water Test. When testing for the Volatile Organic Compounds (VOCs), we may also perform a library search for up to 50 untargeted VOCs, if present, on the output from our mass spectrometer test instrument.1
