Water leaching through the landfill can carry such toxins into the groundwater or nearby bodies of water, and from there into drinking water and the food chain.

Etched lines on the left side waver and blot — the result of what is called, in printmakers' patois, "foul biting," the effect of acid leaching through the wax resist on the plate.

In the mid-1970s, a quarter-century after the Hooker Chemical Company stopped using Love Canal, in upstate New York, as a dump site, suspected carcinogens were found to be leaching through the soil into the backyards of homes built on the banks of the filled-in ditch dug by William Love, who had planned a model community there at the end of the 19th century.

Leech Creek is a stream in Columbia and Sauk counties, in the U.S. state of Wisconsin. Leech Creek was named on account of the water "leaching" through the soil.

Deforestation for clay extraction in Rio de Janeiro, Brazil. The picture is of Morro da Covanca, Jacarepaguá. Clay minerals typically form over long periods as a result of the gradual chemical weathering of rocks, usually silicate-bearing, by low concentrations of carbonic acid and other diluted solvents. These solvents, usually acidic, migrate through the weathering rock after leaching through upper weathered layers.

Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental Protection Agency (EPA). The extract is analyzed for substances appropriate to the protocol.

Even in alluvial soils, root growth may be limited by a hardpan or caliche layer formed by carbonates leaching through the soil and accumulating. As a result, shrub cover is sparse in contrast to other sagebrush-covered ecoregions in Nevada. The grass understory grades from a dominance of cool season grasses, such as bluebunch wheatgrass, in the north, to warm season grasses, such as blue grama (an indicator of summer rainfall) in the south.

Open pit copper mine Skouriotissa in Cyprus. According to data released by the statistical service of the government for the year 2011, mining and quarrying sectors produced a total value of €79.5 million ($105.3 million), which reflected a drop of €46.4 million ($61.4 million) in value- added products, such as finished metal works. This sector employed 534 people. The low-grade copper waste material of the Skouriotissa mines facility has been processed by leaching through the solvent extraction and electrowinning method.

If the gold can not be concentrated for smelting, then it is leached by an aqueous solution: # The cyanide process is the industry standard. # Thiosulfate leaching has been proven to be effective on ores with high soluble copper values or ores which experience preg-robbing: the absorption by carbonaceous components which preferentially absorbs gold and gold-cyanide complexes. Leaching through Bulk Leach Extractable Gold, or BLEG, is also a process that is used to test an area for gold concentrations where gold may not be immediately visible.

This calcium accumulates at high concentrations around the roots and over time is converted into a calcrete. When the roots die, the space occupied by the root is subsequently also filled with a carbonate material derived from the calcium in the former tissue of the roots, and possibly also from water leaching through the structures. Although evidence has been provided for this mechanism in the formation of root casts in South Africa, evidence is still required for its role in the formation of the Pinnacles.Cramer MD, Hawkins H-J. 2009.

Rilling started immediately above the toe button, and from there it crafted as a continuous spiral to the neck, interrupted only at the joint. Rilling was peculiar to the eastern Mediterranean in the first millennium AD and has been found on several ceramic forms in a number of sites (Pedersen 2008: 82). The interior faces of many sherds and amphora bodies were coated with a blackish substance, reminiscent of Mediterranean wine amphoras that were sealed with a resin to prevent the liquids inside from leaching through the ceramic. One sherd, comprising approximately the lower 15 cm of an amphora, was split vertically down through the toe button.

Thousands of sites exist where it is possible to collect natural coloured sands for craftwork, with an enormous range of colours being available around the globe varying with the contents of the mineral charged waters leaching through the sands. But for the tourist the vertical sand cliffs at Alum Bay on the Isle of Wight form the central portion of a visual geological phenomenon (best viewed after a shower of rain) which encapsulates the impressive chalk spires of The Needles and Tennyson Downs. Although tourists are no longer encouraged to obtain their own sand from the cliffs, numerous companies on the Island sell sand for the purpose of Sandpainting. After her marriage to Prince Albert and having chosen Osborne House near Cowes to be her new family retreat, Queen Victoria was the prime mover in the gentrification of this former backwater, local artisans benefitted from the influx of wealthy visitors, and a number of craftsmen sold their fixed sand pictures and unfixed sand jars featuring views of the Island as unique keepsakes of the Isle of Wight.
