A pipe built into the blackwater holding tank that is connected to a source of pressurized water via a hose that is used to help flush solids from the holding tank at a dump site. If using a black water tank flush system in a campsite, the use of a back-flow preventer on the end of the hose to prevent sewage from flowing into the potable water ...
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
Oil sludge or black sludge is a gel-like or semi-solid deposit inside an internal combustion engine, that can create a catastrophic buildup. It is often the result of contaminated engine oil and occurs when moisture and/or high heat is introduced to engine oil.
This is often referred to as "auto-refrigeration" and is the basis of most conventional vapor compression refrigeration systems. If the saturated liquid is a multi-component liquid (for example, a mixture of propane , isobutane and normal butane ), the flashed vapor is richer in the more volatile components than is the remaining liquid.

The North Cape oil spill took place on January 19, 1996, when the tank barge North Cape and the tug Scandia grounded on Moonstone Beach in South Kingstown, Rhode Island, after the tug caught fire in its engine room during a winter storm. An estimated 828,000 US gallons (3,130 m 3) of home heating oil was spilled. [1]
Cross section of a vessel with a single ballast tank at the bottom. A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural ...
"Flush deckers" is a common nickname for a series of American destroyers built in large quantities during or shortly after World War I – the Caldwell, Wickes, and Clemson classes – so called because they lacked the raised forecastle of preceding American destroyers, thus the main deck was a flush deck.
