Is the average ground water velocity used in the sensitivity determination horizontal or vertical velocity?
The average ground water velocities for the major aquifers in the state were calculated using hydraulic conductivity ranges and potentiometric surface maps published by the U.S.G.S. The resultant velocities are horizontal velocities. • What is the depth of soil recharge considered in the sensitivity analysis? Does it take into account confining layers? The soil recharge potential map constructed by the Louisiana Geological Survey is being used for the sensitivity analysis. The interpretations are based on soil characteristics up to 6 feet below land surface. This do not take into account any deeper confining layers. However, the heavy weighting on the well depth factor indirectly takes confining layers into account, as deep wells are usually protected by these layers. • Has there been any attempt to locate abandoned oil & gas production brine/mud pits? There have been shallow ground water problems (shallow subsurface – 30 to 40 feet deep) associated with these pits. According to the pi
