The most common causes of low well yield can be traced to the initial well installation.If the well screen Is not installed In <br /> a suitable aquifer the well will not yield suitably.Also poor well development at the time of well completion will substantially <br /> affect the well's future yield. This Is especially true for monitoring wells which have extended time intervals botween sam• <br /> plingi.You cannot readily address these problems at this point In time. <br /> 2. if using an optional scroen, make sure the screon Is completely submerged In wolf fluid(e.g.If in using a 5' screen,only 3' <br /> extends into the well fluid,the pump will not work because of air leakage through the exposed T of screen.) <br /> r���rn�r�ra►•�r��m�n _ <br />�P. 0.
