Office of Water Quality Technical Memorandum No. 2006.01
Office of Ground Water Technical Memorandum No. 2006.01

SUBJECT: Storage of Water-Level Data for Ground Water

This memorandum specifies and clarifies U.S Geological Survey (USGS)
requirements for the storage of water-level data collected at wells. The
requirements apply to all USGS-related National, regional, and local
programs and projects that measure water levels in wells. Projects for
which water-level data are collected include studies for which data on
water quality, aquifer chemistry, and microbiology might be a primary
focus.

STORAGE REQUIREMENTS FOR WATER-LEVEL DATA

All ground-water-level data must be stored in NWIS (Brunett and others,
1997, p. 13), as specified below.

  1. All time-series (continuous) ground-water levels that can be
    stored in the NWIS Automated Data Processing System (ADAPS) must be stored
    in that database.
  2. All discrete measurements of ground-water levels collected as part of
    water-quality as well as ground-water data-collection activities must
    be stored in GWSI.

FUTURE PLANS

The Offices of Ground Water and Water Quality are unified in their goal to
avoid duplication of data entry and inconsistency within NWIS subsystems.
For example, with version 4.1 of NWIS, water-quality field measurements
(pH, dissolved oxygen, etc.) that previously were stored in GWSI were moved
electronically into QWDATA. Although a timetable has not been set, the
Offices are determined to continue working toward a single-entry system for
water-level data.
