About this file

Written by GovTribe AI ·

This is a site drawing and monitoring well data file for the El Portal Landfill at Yosemite National Park, showing locations and measurements from five monitoring wells (MW-1A through MW-5) taken between 2004-2018. The drawing depicts the layout of the facility, which includes an El Portal maintenance facility, storage yard, three ponds, sludge drying beds, and a waste water treatment plant along the Merced River on Foresta Road.

The file contains detailed coordinate data and well depth measurements taken monthly or bi-monthly over a 14-year period. The monitoring wells are positioned around the perimeter of the former landfill boundary, with elevations ranging from 1683.64 to 1690.50 feet. Well depth measurements show seasonal variations, with depths typically ranging from 2-16 feet across all wells throughout the monitoring period. The data demonstrates consistent long-term monitoring of groundwater levels at this waste management facility, with measurements taken at specified intervals according to a regular schedule.
