n mismatching of the well to the native formation will have to be addressed and corrected (to whatever extent is possible) with well development actions, alone. Well development work can be directed in two ways: First, specific well development actions can be called for by the geologist who installed the wells or by another professional reviewing that installation work. Typically, consultants specify the use of certain equipment and techniques. Second, the consultant or client can define the goal which is being sought and place limits on the amount of effort which should be taken to achieve the goal. Of the two types of direction, the second is far more common and also more important. Defining the extent of effort which can be expended is vital to controlling costs on a project and scheduling personnel and equipment to complete the work. Moreover, it is possible to undertake and complete work without the added and frequently unnecessary effort of working out very detailed specification which may be impractical or unwarranted. This does not mean that our personnel cannot make use of well installation logs when they are available or are not receptive to very specific directions from the consultant. It does, however, mean that when very detailed directions are given, rapid communication between our personnel and the geologist become very important. This is especially true of sites where multiple wells have been installed, because wells even a short distance apart may demonstrate quite different characteristics which may require a rapid -' reevaluation of what well development procedures are appropriate in light of the hydrologic condition presented by the native formation at that location on the site. In most cases, tightly controlled action sequences are less productive than more general directions combined with plain statements of what evaluation criteria should be used for judging the progress and completeness of the well development work. The most common standards are volumetric (removal of set volumes of water), recharge rate, and water clarity (measured as nephelometric turbidity units). Given these goals-and limitations, our personnel can proceed with the work without supervision or direction by relying on empirical information obtained directly from the water in the well Selection of Development Equipment Each Blaine Tech Services, Inc. vehicle provided for a well development project will have a wide assortment of development tools including stainless steel surgeblocks and swabs, several types of pumps and complete instrumentation for determining standard parameters. Special equipment which included certain types of winches,jetting heads, and drop surging pumps can be provided.
