What is Iron Ochre and can I get rid of it?
From the Minnesota Dept of health:

Iron bacteria are small living organisms that naturally occur in soil, shallow groundwater, and surface waters. These bacteria combine iron (or manganese) and oxygen to form deposits of “rust,” bacterial cells, and a slimy material that sticks the bacteria to well pipes, pumps, and plumbing fixtures.
At least 18 types of bacteria are classified as iron bacteria, long thread-like bacteria that “feed” on iron and secrete slime. Unlike most bacteria, which feed on organic matter, iron bacteria fulfill their energy requirements by oxidizing ferrous iron into ferric iron. When ferrous iron is converted to ferric iron, it becomes insoluble and precipitates out of the water as a rust-colored deposit. Once the cells begin to decay, they release a reddish or brownish slime material. This process can occur simply by exposing iron-rich groundwater to the atmosphere. Slimy and clumpy deposits are likely caused by iron bacteria.

Is it Dangerous or Harmful?
Iron bacteria are of no threat to human health. They are found naturally in soils and water in low numbers and will thrive as more iron becomes available. However, the orange slime in the water or leaching from the shore is often considered to be an aesthetic problem. The oily sheens created by the decomposing bacteria cells are often mistaken for petroleum sheens.
Can I get rid of iron bacteria?
The best treatment for an iron bacteria problem is prevention. To thwart these obnoxious bacteria, have all fill material analyzed for iron content before using or exposing it. Unfortunately, once established, iron bacteria problems are difficult, if not impossible to correct.
