Rio Grande aquifer system
Santa Fe Group
LOCATION - Lat 35°03'59.45", long 106°33'51.83" referenced to North American Datum of 1983, in SW 1/4 SE 1/4 NW 1/4 sec.30, T.10 N., R.4 E., Bernalillo County, NM, Hydrologic Unit 13020203,
REVISIONS HISTORY -
Discrete water-level values were revised because the MP correction was incorrectly calculated for the 2016 aquifer test, including values from 11/07/2016 11:15 MDT to 11/14/2016 11:41 MDT. Incorrect old values are documented in the NWIS remark for each water level. The MP height (-0.5) was incorrectly added instead of subtracted. The correction makes the new depth to water 1.00 ft deeper than previously.
Continuous water-level data was revised in Aquarius to match the revised discrete water-level values. The affected period of continuous data has been marked with the "Revised" qualifier and a note was added to document the change.
