ABSTRACT
This study aimed to determine the physicochemical parameters in some selected borehole and dug well water within Fika local government area, Yobe State. Ten (10) sample were collected, two (3) Borehole water and seven (7) Hand dug – well water from different locations and were cleaned in plastic container sealed and transported immediately to the laboratory for analysis. Heavy metals were analyzed using AAS (Atomic absorption spectrophotometer). From the experimental resultit shows that the concentration ofCu,Pb, Zn, Cr and Fe in the samples all conformed to the requirement of WHO, NSDWQ and SON standards. But the concentration of cadmium (Cd) in all the samples exceeds the limit. The physical parameters such as pH, conductivity were conformed to be within the standard limit except turbidity which exceeds the limit in sample (DWC, DWD, DWE, BHF, DWH and DWJ). It is concluded that all the Hand dug well water samples are not absolutely good for drinking as stipulated by WHO. It is also recommended that the sources of borehole water required frequent treatment to meet the standard for portable drinking water. Therefore, people should use the Borehole water often than the hand – dug well water as regard to areas without doubt.

INTRODUCTION
Water is the most crucial and precious natural resources, it is very important in the life of all living organism, plant and microorganism to the most complex living system known as human body (Ojo et al., 2005). Water of good quality is significant to human physiology and man’s continued existence depends very much on its availability (Lamikanra, 1999).Water a combination of hydrogen and oxygen atoms, with a chemical formula H2Oand known to be the most abundant compound at about seventy percent (70%)on earth surface. it is significant due to its unique chemical and physical properties (Obi et al, 2004).
Therefore, water supplied system for peoples intake neither must not surround by pathogens, germs, or harmful/toxic chemicals because water which when adulterated such with microorganism can cause epidemics (a wide spread outbreak of an infectious disease). I.e. good
