Contaminant database

How to read this table…

The aim of this table is to have updated knowledge of the contaminants that we find in drinking water – what they are, what we know about them and how capable distillation, carbon filters and membrane filters (RO, NF, UF, MF) are to reduce/remove them from drinking water.

For membrane filtration, especially of the reverse osmosis (RO) type, there is large variations in quality on the market. Ratings are given for large-scale production systems, and some home systems may not be able to meet the same quality standards.

Our assumptions: Contaminants are assumed to be retained by distillation if their vapor pressure is equal or lower to 53 mPa and at the same time have a boiling point (respectively melting point if there is no boiling point) of 140 °C or higher. These assumptions are based on experimental data from Hanson,2004; Bills,1967 and Hoff,2019, whose retained contaminants have the threshold values mentioned above. Vapor pressure and boiling / melting temperature are the most critical parameters for contaminants, when separated per distillation. 

The removal efficacy is divided in three ranges, adapted from Ruel et al.: Red (below 30% removal) – Yellow (between 30% and 70% removal) and Green (higher than 70% removal).
