Rainwater characteristics can reveal emissions from various anthropogenic and natural sources into
the atmosphere. The physico-chemical characteristics of 44 monthly rainfall events (collected between
January and December 2012) from 4 weather stations (Bamenda, Ndop plain, Ndawara and Kumbo)
in the Bamenda Highlands (BH) were investigated. The purpose was to determine the sources of
chemical species, their seasonal inputs and suitability of the rainwater for drinking. The mean pH of
5 indicated the slightly acidic nature of the rainwater. Average total dissolved solids (TDS) were low
(6.7 mg/L), characteristic of unpolluted atmospheric moisture/air. Major ion concentrations (mg/L)
