Environmental conservation

lapse rate

Environment; Environmental conservation

The rapidity with which temperature decreases with altitude. The normal lapse rate is defined to be 3. 6 degrees F per 1000 feet change in altitude. The dry adiabatic lapse rate is about 5. 5 ...

latent heat

Environment; Environmental conservation

The heat (energy) absorbed or released as water changes between the gas (water vapor), the liquid (water droplets), and the solid (ice) states.

law of mass action

Environment; Environmental conservation

The law stating that for a reversible chemical reaction the rate of reaction is proportional to the concentrations of the reactants.

leachate

Environment; Environmental conservation

Water containing contaminants which leaks from a disposal site such as a landfill or dump.

leachate collection system

Environment; Environmental conservation

A system installed in conjunction with a liner to capture the leachate that may be generated from a landfill so that it may be taken away and treated.

leaching

Environment; Environmental conservation

Extraction or flushing out of dissolved or suspended materials from the soil, solid waste, or another medium by water or other liquids as they percolate down through the medium to groundwater.

leaky confining layer

Environment; Environmental conservation

A low-permeability layer that can transmit water at sufficient rates to furnish some recharge to a well pumping from an underlying aquifer. Also called aquitard.
