groundwater is a common cause of contamination.9 Physical disruption of aquifers can occur from blasting which can cause the groundwater to seep to a lower level or even connect two aquifers (leading to contamination of both). When a mine is located below the water table, water seeps into the mine and has to be pumped out. This

Tenino and Bucoda are both situated above narrow, shallow aquifers surrounded by tertiary bedrock, as evidenced by the sandstone quarries and sandstone-front buildings in these towns. The maximum thickness of the alluvial aquifer penetrated by wells in both the Bucoda and Tenino vicinities is approximately 100 feet.

GROUNDWATER IN THE AGGREGATE INDUSTRY

Above-water pits and quarries can have a beneficial effect on groundwater and aquatic resources. Below-water pits and quarries can be operated without significant groundwater impacts if they are carefully designed and operated. Permits to Take Water ensure that aggregate wash plants do not harm water resources.

Although land fill construction are typically in less vulnerable areas they may need to be considered as well, Landfills are themselves considered as threats to the groundwater quality which is different than the pits and quarries.

groundwater may be pumped locally to dewater quarries to facilitate mining. The dewatering of a quarry can locally lower the water table and may cause nearby water-supply wells to go dry. Additionally, lowering the water table can potentially change the direction of groundwater flow and affect the movement of contaminants in the aquifer.

Chain of Lakes that evolved over the years as the mineral resources were mined and the pits that remained become filled with groundwater. These lakes provide a number of valuable water-related functions, including storm water management, seasonal water storage, groundwater recharge, and wildlife habitat.

Hydraulic Impacts of Quarries and Gravel Pits

(LGUs) often lack the expertise to assess ground-water models (Southwick and others, 2000). Quarries and pits can affect ground-water and surface-water systems in various ways. This project focused on the following potential impacts: lowering of local ground-water and surface-water levels from mining operations and mine dewatering,
