- W2314458452 abstract "Animal waste generated from concentrated animal operations is usually stored in lined earthen lagoons. These lagoons are lined either with clay or goesynthetic materials to minimize seepage of contaminants into the subsurface. Animal waste is rich in nitrogen with significant amounts of suspended solids content. As the lagoon is filled with animal waste, the suspended solids settle to the bottom of the lagoon and physically block the pores of the liner material, reducing the hydraulic conductivity of the liner. In addition to physical blocking, chemical and biological interactions between the waste and the liner material will further reduce the hydraulic conductivity of the liner. These mechanisms effectively reduce the amount of contaminants leaking from the lagoon into the subsurface and groundwater. The sludge formed above the liner occupies a significant volume of the lagoon. To reclaim the lost volume, lagoons are frequently emptied to remove the sludge. In the present study, three scenarios were simulated using the computer program SWMS-2D (Soil Water Movement and Solute transport in 2D) to assess the impact of sludge removal and liner clogging mechanisms on the transport of ammonium (NH4—N) into the subsurface. These scenarios are as follows: i) scraping the top portion of the lagoon liner along with sludge, ii) scraping and replacing the top portion of the lagoon liner, and iii) hydraulic conductivity reduction of the liner due to clogging. The transport parameters of NH4—N and the hydraulic properties of the clay liner were chosen from laboratory experimental studies from previous related research. It was found that scraping the liner in addition to removing the sludge mat increased NH4—N contamination into the subsurface. On the contrary, the scraping and replacing method was an effective means for decreasing NH4—N movement into the subsurface. Also, liner clogging mechanisms significantly reduced NH4—N contamination into the subsurface." @default.
