The Importance Of Mudboils In Tully Valley

The mudboils in Tully Valley are caused by artesian pressure. To reduce mudboil sediment discharges from the mudboil depression area to Onondaga Creek, remedial measures were implemented. This includes installing depressurizing wells along Onondaga Creek and around the mudboil depression area to decrease the artesian pressure. Since the majority of mudboils in Tully Valley are located near the Onondaga Creek mudboil passageway and mudboil tributary diversion channel, the majority of the depressurizing wells is placed near those locations as a result. A dam was constructed in Tully Valley to create a settling captivity were detained water also maintains hydraulic pressure over the mudboils and constructing a dam also helps decrease

Salt solution near Onondaga Lake formed as a result of the dissolution of halite from the Tully Valley. The salty groundwater naturally flowed from the high elevation at the southern end to the low elevation at the northern end. According to Kappel, the artesian pressure in Tully Valley is exacerbated by dissolution of a halite bed below confining beds of shale, till and glacial sediment. As a result, mudboils in the valley, ultimately flow saline water and will contribute both saltwater and sediment to Onondaga Creek. The salt marshes along the coast of Onondaga Lake are inadequate for the quantity of salt needed to produce soda ash. As a result, the mining of salt brine began in Tully Valley. Mudboils with an enclosed brackish water source and halite deposits in the Onondaga lake which can be a source for soda ash production. Soda-Ash is produced from the salt solution in Tully Valley. This process is known as Solvay's process as it is used for industrial production of Soda ash this is …show more content…
Mudboils influenced Tully Valley’s Water quality, in the Onondaga Creek, byproducts from sewage discharged that contain harmful and pathogenic bacteria led to the mix up of the water sources inside the mudboils leading to a climax of brackish as well as freshwater with pollutants. This impacts the water clarity and quality, the sediment in the water that is discharged in the Onondaga Lake impacts causes concerns about the aquatic life. This could also impact the health of the entire ecosystem of Tully Valley as the sediment that is discharged into the creek affects aquatic species, the terrestrial species that primarily eat aquatic species such as fish and used the creek as drinking water would also be impacted. In aquatic life, the different pressures in and around the mudboil can lead to the decline and ultimately collapsed the aquatic life since there is contamination with pollutants led to changes in dissolved oxygen, pH and temperature.
Installing depressurizing wells is one method used to reduce the negative impact of the mudboil have on Tully Valley and relieve the tensions of it is depressurizing wells. Majority of mudboils in Tully Valley are in the Onondaga Creek mudboil passageway and Mudboil tributary diversion channel, this result majority of the depressurizing wells to be placed in these locations.
