These structures or disturbances have the potential to increase the speed at which surface or groundwater can flow to the well, hence reducing the timeof-travel (i.e.- an abandoned well is a direct conduit to the aquifer below, bypassing the overburden that a

Groundwater levels fluctuate substantially in the Basin due to natural infiltration from major storms, managed surface water spreading operations along the San Gabriel River, and long-term wet and dry climate cycles that normally affect southern California. Historic high groundwater

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.


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.

A pit lake usually forms at some point in time after mining stops and the groundwater pumps are turned off.

Some car-bonate rocks contain valuable supplies of water, oil, and gas, may weather to form bauxite deposits, and are associated with manganese and phosphate rock (guano). Coal is often found within thick carbon-


CBS has conducted extensive groundwater investigations at the BD site and determined that the recharge areas for site groundwater are to the east and southeast of the site. Much of the groundwater and surface water in higher elevations to the east of the site is intercepted by open quarry pits. These pits were left unfilled at the end of active

Water can also penetrate fractures and accelerate weathering processes. Freeze-thaw cycles cause expansion of water filled joints and loosen highwall material.

Based on this analysis it is unlikely that the water supply of neighboring homeowners will be noticeably affected by the quarrying operation.

(Q9) Does the plan discuss non-storm water discharges? The SWP2 plan must identify all non-stormwater (dry weather) discharges directed to surface or groundwater such as pit dewatering. The SWP2 plan shall ensure the implementation of appropriate pollution prevention measures for the dry weather discharges.

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.


Ground Water Flow Groundwater flow is the part of stream flow that has infiltrated the ground, has entered the phreatic zone, and has been discharged into a stream channel, via springs or seepage water. It is governed by the groundwater flow equation. Groundwater is water that is found underground in cracks and spaces in the soil,


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,

Extractive Industries Quarries
