(1) Estimated dewatering volume provided by Martin Marietta Materials.
(2) Dewatering water pumped to the Silt Ponds will be metered and reported by Martin Marietta Materials. It is assumed
that the depletion caused from pumping this water from the Duckworth Pit is offset by "recharging" the Silt Ponds.
Therefore, since the Duckworth Pit and silt ponds aquifer parameters are approximately the same, no depletion is
(3) Water pumped from dewatering trenches into the Smith & Emmons Ditch. This volume will be metered and provided
by MMM monthly.
(4) Dewatering water delivered to the river via the Smith & Emmons Ditch. Water delivered to the river will be measured
and provided by MMM monthly.
(5) Lagged depletions from (3). Depletions are lagged using the same methodology and aquifer parameters as shown in
Table 1, Column 7.
(6) Equal to (3) - (4).
