6 Iron and Manganese Removal Handbook levels of manganese in the diet is considered essential for human health. The average daily intake from food is 1–5 mg/day (USEPA 2010). Manganese is detected in approximately 70 percent of groundwater . sites in the United States (WHO 2011), but generally below levels of pub-lic health concern (USEPA 2002).
Dust is defined as "solid particles generated by handling, crushing, grinding, rapid impact, detonation, and decrepita-tion of organic or inorganic materials, such as rock, ore, metal, coal, wood, and grain."1 A wide range of particle sizes is produced during a dust-generating process.

The Aztec 600 Manganese analyzer has been designed specifically for the measurement of manganese in ground waters, surface waters and potable waters. It offers reliable, and accurate, on-line analysis of manganese up to 10 ppm. All the sample and chemical fluid handling for measurement, mixing and disposal is controlled precisely by the patented
Produced water from oil and gas operations is currently handled as a waste product. The quality of produced water varies significantly based on the geochemistry of the producing formation, the type of hydrocarbon produced, and the
Iron and manganese in water also promote the growth of bacteria (including iron bacteria). These organisms obtain energy for growth from the chemical reaction that occurs when iron and manganese mix with dissolved oxygen. These bacteria form thick slime growths on …
Manganese often results in a dense black stain or solid. For these reasons, it is recommended that drinking water have no more than 0.3 mg/L (or 0.3 parts per million) of iron and less than 0.05 mg/L of manganese. The U.S. Environmental Protection Agency has also set a Health Advisory for manganese of 0.3 mg/L.
