The Rockingham County Conservation District in New Hampshire installed demonstration Permeable Reactive Barriers (PRB), a new passive technology used to control nitrogen with a formulation of wood chips, exchange media, and sand or gravel to transform inorganic nitrogen to nitrogen gas. This technology can be used in conjunction with an existing or new septic system to prevent nitrogen migration to sensitive watershed areas. A groundwater monitoring program was used to evaluate the effectiveness of this technology at a small residential and larger community septic system.
In Wichita, Kansas, sandy soils have been mined for commercial purposes, resulting in a sand pit that fills with groundwater. Stormwater drains into the resulting lake from the residential lawns, parking lots, driveways and roads. The Sedgwick County Conservation District along with partnering agencies set up monitoring wells to determine whether pollutants carried by runoff into sand pits affect the quality of the groundwater and to help identify appropriate best management practices to address this.
