Abstract:
Ground water 3~~ples frem eighteen welle which could manifest clearly
the quality of water in the Anuradhapura district, were tested for
:!!eventeenparameters each month. The Para-meters tested. for indicate the
Potability of the water. Water quality variation in relation to the
rainfall pattern was studied to examine the effect of rainfall on the
quality of ground water. The relationship between the parameters was
aIM studied.
The study reveals that tne quality of ground water in the Anuradhapura
district conforms to the majority of the requirements of the Sri Lanka I
standards for potable water (SLS 614). Further, this study highlights
the high levels of Fluoride and Iron; and infa..ctthe levels exceed the
Maximum Permissible Level of the Sri LanKa Standards and Maximum Allowa-
-ble Concentration of the WHO Standards. Hardness and Alkalinity were
also found to be high in some areas. However, high levels of Iron and
Fluoride appear to be the major limiting factors in the ground water
of the Anuradhapura district.
In general, there is a distinct variationof ground watar qualitywith
rainfall changes.
Di1'!tinct interrelationship between pairs of parameterswas observed
only in :cespect to Electrical Conductivi ty versu~ Chlorides and Total
Hardness versus Calcium Hardness.
