Water Treatment of Silica Natural waters, generally, contain about 58 mg/l of silica (Si0,). Another important source of silica in water is the sand When water treated by limesoda process is filtered through a sand water filter, a good amount of silica dissolves in it (forming calcium and magnesium silicates) due to alkaline nature of waters.

Nonoccupational exposure to silica dust can be from industrial as well as nonindustrial sources. Nonoccupational exposure from nonindustrial sources occurs naturally due to desert dust and sand storms in hilly areas.[4,5] Some farming, construction, and demolition activities also contribute to the environmental exposure.
Foundry work, hydraulic fracturing, and other processes that use industrial sand also create environments with respirable crystalline silica. Respirable crystalline silica dust is created pretty much the same way as any other kind of dust, as long as the material being used contains silica.
