Once contamination is detected in a drinking water supply it is
important to use the proper treatment device to remove the contaminant. The
following section is to be used only as a guide to help in the selection of
a treatment device. Before buying a treatment device have the water
supply tested for contamination and consult a specialist when selecting
the best treatment device. If the specific contaminant is known the
information in the contaminants sections will indicate the possible treatment
devices and link to more detailed information in this section.
