Switzerlan d County is loc ated in southeast In dia n a, an d is b oun ded b y the counties of Jefferson, Ripley an d Ohio to the west, northwest an d north, respectively. The state of Kentuc ky b orders the county to the south an d east. The en tire county lies within the Ohio River Basin . The potentiom etric surfac e is a m easure of the pressure on groun dwater in a water b earin g form ation. Wells are com pleted in aquifers at various depths, an d typic ally, un der con fin ed con ditions (b oun ded b y im perm ea b le layers ab ove an d b elow the water b earin g form ation). However, som e wells are com pleted un der un con fin ed (not b oun ded b y im perm ea b le layers) settin gs. Water in a con fin ed aquifer, whic h is un der hydrostatic pressure, will rise in a well ab ove the top of the water b earin g form ation. In contrast, groun dwater in an un con fin ed aquifer, whic h is at atm ospheric pressure, will not rise in a well ab ove the top of the water b earin g form ation. Static water-level m easurem en ts ob tain ed from in dividual wells used to construct county potentiom etric surfac e m aps are in dic ative of the water-level at the tim e of well com pletion. The groun dwater level within an aquifer constan tly fluctuates in response to rain fall, evapotran spiration, groun dwater m ovem en t an d pum page. Therefore, m easured static water-levels in an area m ay differ due to loc al or season al variations. Bec ause fluctuations in groun dwater are typic ally sm all, static water-levels c an b e used to construct a gen eralized potentiom etric surfac e m ap. As a gen eral rule, b ut certain ly n ot always, groun dwater flow approxim ates the overlyin g topography an d in tersects the lan d surfac e at m ajor stream s. The potentiom etric surfac e m ap of the b edroc k aquifers was m apped b y contourin g the elevations of 32 static water-levels reported on well records rec eived prim arily over a 50 year period. U n iversal Tran sverse M erc ator (U TM ) coordin ates, used in loc atin g the water wells, were either physic ally ob tain ed in the field, determ in ed through address geocodin g, or reported on water well records. The loc ation of the m ajority of the water well records used to m ake the potentiom etric surfac e m aps were field verified. Elevation data were ob tain ed from a digital elevation m odel. Quality control/quality assuran c e procedures were utilized to refin e or rem ove data where errors were readily apparen t. On ly a couple of areas n ear the towns of V evay an d M arkla n d alon g the Ohio River had suffic ien t data to draw a b edroc k potentiom etric surfac e. Within these areas, potentiom etric surfac e elevations ran ge from a high of 470 feet m ean sea level (m sl), to a low of 430 feet m sl in these areas. Region al groun dwater flow direction is gen erally towards the Ohio River. Potentiom etric contours have not b een exten ded through portions of the county that are lac kin g in data an d/or covered b y m ore prolific un con solidated deposits whic h lim its the n ec essity to com plete wells in the b edroc k. The county potentiom etric surfac e m ap c an b e used to defin e the region al groun dwater flow path an d to iden tify sign ific a n t areas of groun dwater rec harge an d disc harge. These m aps represen t overall region al c haracteristics an d are not inten ded to b e a sub stitute for site-spec ific studies.
