National Water Information System (NWIS). As part of the program of disseminating water data to the public, the U.S. Geological Survey (USGS) maintains a distributed network of computers and fileservers for the acquisition, processing, review, storage, and dissemination of water data collected by its water resources programs and projects. The USGS's National Water Information System (NWIS) contains water data collected at approximately 1.5 million sites from all 50 States, as well as Puerto Rico, Guam, and many other countries. Data date back to the formation of the USGS in 1879 and includes hydrologic data collected by the Army Corps of Engineers prior to the creation of the agency.

Master Data File: NWIS consists of two major subsystems: the distributed core-NWIS databases, which are restricted to internal USGS use only and are not web-based, and the NWISWeb system. The distributed core-NWIS databases constitute the master data file for NWIS serving as agency's permanent repository for all input data and records that have been reviewed and approved for public distribution. The raw uncorrected data also are preserved in the database. NWISWeb provides the public web-based Internet access to an aggregated database created from the master database. All data and information temporarily served to the public by NWISWeb is obtained from the core-NWIS databases; therefore, data in NWISWeb are duplicate records. The NWIS master file contains more than 850,000 station years of time-series data; monthly, annual, and period-of-record statistics based on these time-series data; more than 3.5 million physical, chemical, biological, and radiological field and laboratory analyses; and other data and records. Also included are summary data on water use throughout the Nation and includes both site-specific and aggregated water-use data.

Summary of data types in master data file:

• Site information - inventory and location information about sites at stream reaches, lakes, reservoirs, ponds, wells, springs, test holes, tunnels, drains, and excavations. Also includes information for water-use sites. Site information is common to all other categories of data stored within NWIS.
• Site owner - information about site owners and water users.
• Time-series data - continuous water level, streamflow (discharge), water quality, and rainfall data.
• Peak flow data - instantaneous maximum (peak) stream discharge and associated water level data at stream sites.
• Ground-water data - includes well construction, non-continuous water level, well or spring discharge, hydrogeologic and aquifer hydraulic, geophysical, and site-visit data.
• Water-quality data - results from field and laboratory physical, chemical, biological, and radiochemical analysis of water and other samples.
• Sediment data - results from physical and chemical analysis of sediment samples.
• Water use data - measurements and estimates of water use at a site or location.

Graphic outputs present the data in formats easier to understand and interpret. An X, Y hydrograph plot, for example, depicts related sets of hydrologic data on the Y-axis and the date/time on the X-axis. This allows the user to visualize trends and anomalies in the data.

A variety of graphs can be output from core-NWIS. Some graphs are specifically designed for the data types being examined, while other graphics are user-selectable. The graphing routines automate unit conversions and rounding routines to present the data in a common frame of reference. Graphic outputs include:

• Hydrographs of time-series data
• Rating Graphs
• Ground Water hydrograph
• Water Quality X, Y Plot
• Water Quality Boxplot
• Water Quality Stiff Diagram
• Water Quality Piper Diagram
• Water Quality Regression Plot

Another important NWIS output is NWISWeb, the public interface to the distributed core-NWIS databases. NWISWeb provides copies of data in NWIS to the public in a variety of formats. All data in NWISWeb comes from the distributed core-NWIS databases. Outputs from NWISWeb are tabular (ASCII-delimited files), HTML, and graphic representations of the data. The tabular outputs are designed for use in applications that support data in row and column format.

Other electronic information comes from users within the NWQL in the form of word processing, spreadsheet, comma separated, and tab separated files generated from personal computers and containing setup and reference information for the LIMS. Manual input is generally entered directly into the LIMS database, but in the case of customer requested reruns, the manual data entry is directed at an intermediate database and then transferred electronically to the primary LIMS database. Manual input consists of data entered from ASR forms, which is the method used to initiate analytical requests from the NWQL; data from instrumentation that cannot be transferred electronically; requests for authorization to update results; and other various manual types of LIMS reference data and setup information using LIMS applications. ASR mandatory fields consist of: station ID, start date, start time, medium code, sample type, user code and district contact.

****1400-31b(2)

Master Data File: LIMS data are stored and accessed on several databases. Data are physically located on a production server, and a replicated database is available for web displays and reports with access by both internal and external sources. There is a production database which consists of a working database and an archive database. The working database contains historical LIMS data dating back to 1998; the archive database contains data generated between 1992 and 1997. Several other databases are used for development, maintenance, and testing of LIMS projects. Reference tables, which are fairly static, contain either information used for LIMS configuration and maintenance, or contain supporting reference information for the data contained in the working tables. The working tables are dynamic tables that contain information pertaining to the analytical requests of the laboratory and are used to store, monitor, and report information about those requests. Reference data includes information about analytical methods and analytes available, calculations, reporting data, rounding and censoring rules, prices, quality-control setup, instrument configuration, special projects, and laboratory structure. Out of these, 80% of the fields are scientific and 20% are non-scientific fields. Working data includes information about the samples, customers, requested analyses, status of requests, billing, analytical results, quality-control results, analytical batches, preparation results, sample containers, container condition, field test data, data release, laboratory reruns, and custom requested reruns. Working data contains 83% scientific fields, and 17% non-combination of the station identification number, sample start date, sample start time, sample medium, user code, sample end date, and sample end time. This information is then used to create a unique folder identification, which is then used as the initial linking field for information tied to that logical key.

****1400-31b(3)

Outputs: Outputs for the LIMS can consist of a variety of formats and media including database export files, backup files, tape backup, e-mail, fixed format files, custom crystal reports, web pages, web reports, ad-hoc reports, LIMS screen displays, instrument control files, and printed reports. Output of completed analytical results can occur through LIMS displays, e-mail, and electronic file transfer to NWIS, or downloads from the User Sample Status web page. Billing information is sent monthly via a fixed format file to the FFS and billing summary information is posted weekly and monthly on the USGS visible NWQL web system. Reports can be generated in a variety of manners either by sending reports directly to a printer or by viewing the report using a crystal reports interface that allows users to either view, print, or export reports in variety of formats including spreadsheets, word processing files, csv, html, and straight text. The mandatory fields transferred from LIMS to NWIS include: sample integer, user code, agency code, station ID number, sample start date, sample end date, medium code, lab ID number, project code, aquifer code, sample type, analysis status, analysis source, hydrologic condition, hydrologic event, tissue sample ID, body part code, lab sample comment, field sample comment, sample time datum, time datum reliability code, parameter code, result value, quality assurance code, method code, rounding code, value qualifiers, report level, report level type, data quality indicator, null value qualifier, preparation set number, analytical set number, analysis date, preparation date, lab result comment, field result comment, and lab standard deviation. These transfers take place on a daily basis. Outputs of information to instruments consist of files that contain sample sequence information, instrument settings, sample information, preparation information, and field information.

****1400-31b(4)

Documentation: This consists of information relating to the data and the development and functionality of the data systems. This includes any testing procedures, quality checking guidelines, government or contractor created manuals and handbooks, records layouts, data elements definitions, code translation tables (codebooks) for coded data, and other related materials needed to interpret the system.

Backup Tapes: Backup is accomplished by loading on the test server first; then, compatibility is verified with the operating system. A thorough testing is then done against the supported applications using test data to verify that functionality is consistent. Backup is done nightly on all servers. Nightly system back-up dumps are done by a system administrator Monday through Thursday. Nightly hot back-ups are done for each data base; cold back-ups are done every Friday. These backup tapes are stored offsite.
