Visual pollution is an aesthetic issue and refers to the impacts of pollution that impair one's ability to enjoy a vista or view. Visual pollution disturbs the visual areas of people by creating harmful changes in the natural environment.
Barite mining boomed in 1926, when it was discovered that the mineral could be used as oil drilling mud. Washington County was the world's leading producer of barite before declining in the 1980s. Figure 1-1. ... Other sites in Washington County are also being investigated for mining-related contamination.

It can therefore be concluded that barite mining has caused pollution by Fe, Hg and Pb of ponds and streams in abandoned mine areas of the study area. The pollution due to barite mining hss not been attention compared to ore minerals, especially in low income country.
----- (2) Blasting barite-bearing shale from open pits. (3) Underground mining of barite veins or beds. (4) Blasting of massive barite from open quarries. Domestic production of barite, by State, is shown in Table 4 in the Appendix. The methods for milling of barite depend upon …
May 07, 2013· Contamination resulted from barite mining activities. Barium concentrations in contaminated soils determined by X-ray fluorescence were in the range 0.13-29.2%. Barite contaminated soils were shown to negatively impact both E. fetida and L. sativa relative to control soil.
Washington County is part of Missouri's Old Lead Belt, where lead and barite mining, milling and smelting occurred over the span of three centuries. The Potosi, Old Mines, and Richwoods Superfund sites encompass approximately 180 square miles in northeast Washington County.

In the early 1900s, several thousand people mined galena and barite in Washington County. Small pits and hand mining gave way in 1924 to mechanized mining. Barite mining boomed in 1926, when it began to be used in oil drilling mud; this also increased production of associated galena.

Contaminants Found in Groundwater ... Enters the environment from mining operations, processing plants, and improper waste disposal. Found in low concentrations in rocks, coal, and petroleum and enters the ground and ... Following rainfall, variations in groundwater turbidity may be an indicator of surface contamination.
Barite mining boomed in 1926 as the mineral's use for oil drilling mud was discovered and for a number of years, Washington County was the world's leading producer of barite before declining in the 1980s. Many of the later large mining operations reworked lands that were previously hand mined for galena (mineral source of lead) or barite.
Sources on contamination include CO 2 (from formation, formation water, aeration at surface), overtreatment with bicarb and soda ash (for gyp or cement), thermal degradation of organic additives, and contaminated barite or bentonite. The proportion of carbonates to bicarbonates is a function of pH.
