Abstract
The Louisville Water Company constructed a 76,000 m3/day capacity radial collector well and started pumping from the alluvial aquifer in July, 1999. After start-up, the specific capacity of the wellfield was measured to be much greater than was predicted during the design phase, and after one year of pumping additional riverbank filtration (RBF) capacity was planned using these higher estimates of specific capacity. Subsequent years of pumping indicated a steady decrease in specific capacity, and designs for additional RBF capacity was adjusted based on more reliable estimates of long-term sustainable yield. This paper reviews the data collected from this site, provides calculations of specific conductance over a 5 year period, and interprets data into values for riverbed conductivity at start-up and after 5 years of operation.
