This study has been on wells water and river to detect some quality and biological properties of groundwater and river, within Alfalluja City. In addition, start examined the environmental characteristics (physical, chemical and biological factors) during the study period from June 2013 to April 2014. From result was narrow variance in plurality wells water temperature, EC values almost wells high recorded and the total dissolved solids in wells was recorded high values too. compared with unacceptable for drinking use as standard world values, The PH values were narrow ranged because buffering capacity to bicarbonate, And almost wells water were hardness, Almost wells were high recorded values to calcium, magnesium, sodium. Plurality wells water to Chloride values was did not walk past.
The acceptable boundary and sulphates values was high recorded but nitrate, phosphate values low recorded. In the qualitative study of phytoplankton it's found in four wells only 2-5-7-8, The algae diagnosis six genus, Four genus from diatoms algae class (Gomphonema sp, Navicula sp, , Cymbella sp, Fragilaria sp) and one genus from blue-green algae (Oscillatoria sp) and last genus to Euglena algae class (Euglena sp).
