groundwater

Water below the earth's surface, saturating soil and rock at the level of the water table and below. It supplies approximately 35 percent of the drinking water in the country and, as such, is a source of much concern for the Environmental Protection Agency. If one purchases a property with contaminants, and those contaminants have leached into the groundwater, then remediation will usually be required before development can proceed.

A few data points showed apparent positive Ce anomaly caused by a negative La anomaly (as defined by Bau & Dulski 1996), and one data point from the Nostolepis body scale showed a real positive Ce anomaly, likely reflecting pore water anoxia present in most of the depositional settings.

Regardless of depth, investigations of diagenesis must take into account the conditions during and right after deposirion, which determine the types and amounts of primary porosity and the chemistry of the pore water that may or may not have been buried with the sediments/rocks.

At the boiling point of water, 212 [degrees] F (100 [degrees] C), this pore water expands as a gas (steam), and can explode a pot if it can not escape.
