Abstract:
Malwathu Oya is located in Anuradhapura district which has water quality and
scarcity problem for drinking purpose. Samples were collected from selected
locations which included upstream and downstream of Malwathu Oya basin. The
samples were analyzed for conductivity, pH , turbidity , calcium, magnesium,
fluoride, chloride and arsenic. Only shallow regolith aquifers are considered for the
study. The quality variation of the area shows a considerable variation from southwest
monsoon to second inter monsoon period. In general, water quality of the area
is inacceptable limitd of drinking water for most of the basic parameters. With the
seasonal changes, fluoride and chloride content is higher than permissible limits in
some areas.
