Methods: Physical & Chemical *): B. Examination of the auction hall's tap water test report (comparing them to the borehole water) indicates that the bacterial count is slightly lower but not enough to be considered sanitary and fit for drinking. The turbidity also dropped dramatically between borehole and tap, indicating deposition of.   The Pure water boils at degrees Celsius and freezes at 0 degrees Celsius, The high boiling point and the low freezing point of the water are due to the presence of the hydrogen bonds between its molecules. The water density decreases on freezing The density of the water in the solid-state (the ice) is lower than its density in the liquid state as when the temperature of the water .

MATERIALS AND METHODS. The Water Samples were collected from four Different places in the Morning Hours between 9 to 11am, in Polythene Bottles. The Water samples were immediately brought in to Laboratory for the Estimation of various Physico-chemical Parameters like Water Temperature, pH were recorded by using Thermometer and Digital pH Meter. The initial stages of physical evidence examination can be pivotal to the successful resolution of criminal investigations. In the present paper we intend to point and offer some guidelines for the methods employed in the recognition, collection and preservation of physical evidence used for DNA analysis.
