January 28, 2021

Agenda:

1.	WQX Project Status Report

2.	Water Quality Portal Project Status Report

3.	Open Discussion

The next User Meeting is scheduled Thursday, February 25, 2021 at 12 p.m. EST

1. WQX Project Status Report

For the next two quarters the WQX project will focus on the following tasks:

•	O&M -- Operation and Maintenance: Bugfixes and enhancements

•	QAQC Services - The WQX team is still working through the requirements for this service. It will
be a post processing report that is downloadable from the data submission report files in WQX.
These new files will be included with the Processing report and the schema validation file.

The Monitoring Location QAQC Report will evaluate the latitude/longitude which are the only the
mandatory geographical fields for monitoring locations. The QAQC service will evaluate the 3-
digit decimal precision of the lat/long, identify duplicates, and it will generate state, county, and
HUC information. This may facilitate increased accuracy in latitude and longitude info for data
owner monitoring locations.

2. Water Quality Portal Project Status Report

The WQP has migrated to an Amazon platform environment and from an Oracle to Postgres hosting
environment. The develop team is fine tuning the performance of this application and addressing issues
outlined in the (Link to Open WQP Tickets) Querying by Projects is a known bug and is slated to be
resolved by the next quarter.

•	Usability Testing Group - This will focus on the Water Quality Portal application and website.
Various target groups will be identified to visit the application and identify whether the tool is
intuitive for certain use cases.

•	WQP Download Profiles Workgroup -

This is a formal workgroup with bi-weekly meetings. The workgroup objectives are to streamline
the data download profiles, rename the file names, define the selected elements returned in
each file. If you want to join this workgroup, contact the help desk at wgx@epa.qov.

3. Open Discussion / Other items:

As a preliminary usability study, the WQX Team is archiving selected helpdesk ticket responses in the
homepage's (Frequently Asked Questions) FAQs webpage. This will assist with application
troubleshooting and data submission resolutions. New questions will be integrated with the current
FAQs via URL located here:

Domain Value Services - The characteristic/taxon submissions can be submitted based on alias type =
"WQX SYNONYM REGISTRY (validation)" which identifies allowable values --valid for submission, i.e.,
WQX supports submitting CAS # for the characteristic name. The Taxon domain uses the same alias
type = "WQX SYNONYM REGISTRY (validation)" that flags allowable ITIS synonyms for registered
taxon. Remember to submit the optional elements "Characteristic User Supplied" and "Subject
Taxonomic Name User Supplied" to store the synonym name for retrieval. Data submitters may email
request for registering synonyms recognized by authoritative resource.
