Quarrying was first used by early settlers in Britain for building stone and extracting metals for weapons. It continues as an industry that involves the extraction of rocks like limestone and slate.
Quarries are known to cause sinkholes, damage groundwater tables, and increase the risks of experiencing soil erosion, even when managed properly. 2. Quarries create difficult traffic patterns. Limestone quarries may create jobs, but they also create costs. Traffic can be a major problem for small communities near a quarry.
The metal concentrations in the quarry soils from the different areas are highly variable, especially Cr pseudo-total contents (Table 2); this is related to the occurrence of metal ores, whose accumulations depend on natural and anthropogenic factors, like historical quarrying, as well as on how the waste was deposited, among other factors.
The 1850 Mining Journal contains details of the proposed lead mines at Itchington near Alveston. Quarrying for limestone had exposed ore at the junction of the Limestone with the red marl and Sandstone. When samples were tested it was found that they contained 55-60% lead and 68-71 ounces of silver per ton of ore.

Mining of coal and metallic minerals in Washington began in the mid to late 1800s. Coal production in Washington hit a high in 2003 with an estimated total production of 6,232,000 short tons, yet production ceased in 2006. Metals mining during the same general time period occurred on both sides of the Cascade divide, but was largely concentrated in the northeastern portion of
