Before issuing its regulatory determination, the U . S . EPA issued a recommended Drinking Water Equivalent Level ( DWEL ) for perchlorate of 24.5 �g / L . In early 2006, EPA issued a " Cleanup Guidance " for this same amount.

At the Blazed Alder Creek station, the highest of the three at above sea level, the mean snow-water equivalent ( SWE ) ( the amount of water in the accumulated snow ) ranged in 2009 from 0 in July October to about in April.

The muon flux ( and thus water equivalent depth ) in CJPL-II has not yet been measured, and may differ slightly from CJPL-I, but it will certainly remain lower than SNOLAB in Canada and thus retain the record for the world's deepest laboratory as well.

If completed as initially planned, Homestake would have been the deepest underground science facility in the world, below ground ( 7200 meters of water equivalent, for cosmic-ray shielding purposes ), deeper than the current record holder, the China Jinping Underground Laboratory below ( 6720 mwe ).

Initial snowmelt models used a degree-day approach that emphasized the temperature difference between the air and the snowpack to compute snow water equivalent, SWE . More recent models use an energy balance approach that take into account the following factors to compute " Q m ", the energy available for melt.

The Mars Odyssey neutron spectrometer observations indicate that if all the ice in the top meter of the Martian surface were spread evenly, it would give a Water Equivalent Global layer ( WEG ) of at least H " in other words, the globally averaged Martian surface is approximately 14 % water.

January 1895 saw heavy snowfall produce above average water equivalent precipitation England and Wales averaged which is more than in any colder month since the EWP series began except in the west of Scotland which was in a rain shadow from the prevailing northeasterly winds and received only a quarter of normal rainfall.

:( EC ) For a large object in a stable configuration, the object will float if the mass of the object is no more than the mass of a volume of water equivalent to the portion of the volume of the object that s below the surface of the water, i . e ., the mass of the object is no more than the mass of the displaced water.
