Data are valuable, plan for re-‐use Electronic data are more valuable than data in file cabinets The more data are re-‐used, the more valuable they become ◦ Collect once – use mulKple Kmes
Is a component of your grant requirements Shared data are of even higher value ◦ Provide for beOer planning decisions and incenKvize collaboraKon ◦ Make the most use of your data collecKon Kme and resources being invested
Provides sustainability through turnover and program life cycles ◦ Once you’re gone, it makes the data available to others

-
Top reasons for not sharing data Don’t know how Don’t have Kme Too difficult to format chemical and biological data The chemical or taxonomic names don’t match Don’t have the IT or data management resources Cant submit all chemical or biological data elements to WQX
Its not my job, that’s IT work

What is the Water Quality eXchange (WQX)?
WQX defines the framework by which EPA compiles water quality monitoring data (biological, chemical, physical) in STORET
WQX provides a community standard of water data fields to improve water data sharing
WQX helps you to parKcipate with over 400 WQX users on the Water Quality Portal
Combined, WQX and the Portal increase the value of your data by making it available to mulKple users

Water Quality Portal

With the NaKonal Water Quality Monitoring Council (NWQMC), the Water Quality Portal (WQP) integrates publicly available water-‐quality data, through use of the Water Quality eXchange (WQX), from the USGS NWIS, EPA STORET, and USDA ARS STEWARDS.

WQX Summary
29
Reduces your effort to use other data sources ◦ Delivers data from mulKple sources in a single file format
Leverages and protects investments in monitoring data Supports water quality based decision making ◦ Comparing to water quality standards ◦ IdenKfying hotspots ◦ Developing protecKon and restoraKon plans ◦ Modeling expected changes
-
Next Steps Manage your data NOW to capture all your data correctly ◦ IdenKfy methodologies, biological intent, assemblages sampled, etc.
◦ Maintain a list and update your taxon annually Start to incorporate data rules into your business pracKces to make the transiKon smoother – e.g. metadata ◦ Map your data to WQX allowable values
IdenKfy who needs to work together in state – manager, lab technician, chemist, biologist, IT staff ◦ Help IT staff to format data, ensure data are accurate and share data with WQX
