The Freshwater Explorer is an interactive web-based tool that provides the status of salt and
mineral content in freshwater resources for streams in the lower 48 states. The data is
comprised of both WQX and NWIS data from WQP.
The tool was developed to make salt and mineral content information more accessible to users
by providing information on the status of water resources for a network of steams and predicting
and measuring freshness. Susan explained how the model was created and discussed the
issues found with the data reported in WQP. When ORD started they tossed 50% of the data.
Then they decided to flag data with issues.
Erroneous data such as salt contents with negative counts, data reported as |jS/cm but likely
measured as mS/cm need to be addressed. Susan asked data stewards to review their data by
reviewing the spreadsheet she referenced. Data is broken down by state and each organization
is listed. The spreadsheet contains a worksheet to select the link to and query the questionable
data in
WQP.
The spreadsheet is located at: ftp://newftp.epa.qov/storet/xfer/How/2019-04-25/
WQP_Data_Summarization.xlsx
The plan is for ORD to release the application. ORD would like feedback on the application and
data stewards to help cleaning up the data flagged for issues. ORD would like pull the data

from the WQP again before publishing the Storybook. ORD also plans to make an explorer
tools for other parameters such as nitrogen.
Susan opened the floor to questions:
	Dwane Young reminded data stewards that WQX business rule require the entire
sample to be uploaded. Correction submissions for Individual results require the
uploading the entire sample. If the entire sample is updated, it will overwrite all the
information for that sample.
	Dwane confirmed that the |jS/cm to mS/cm units are input into WQX that way and are
not translated by WQP. If it goes into WQX that way, then it comes out in WQP that
way.
2) Domain Value Change Notification Alert - Kevin Christian
ftp: //n ewftp. e pa. g ov/storet/wqx/do m ai n a lerts/
a.	Characteristic and Taxonomic names - are impacted by our reference systems
SRS Characteristics, Taxon - ITIS and Bio Data
b.	deprecated, retired, and duplicate value resolution
One of the challenges in stewarding WQX domain values is communicating domain changes to
the user community.
Characteristics and Taxonomic names are updated on a daily basis. They are impacted by
reference systems, SRS for Characteristics and ITIS and Biodata for Taxonomic names.
The WQX will leverage the ftp site to keep the user community informed on updates to
Characteristics and Taxonomic domains. An update for Characteristic changes was recently
sent out. Kevin is hoping to release an update for Taxonomic name changes and the impacts to
organizations.
ITIS system is fully vetted. Diatoms are always changing and ITIS tracks this information. Kevin
references ITIS for retired diatoms. He retires Latin names that are synonyms of valid taxon
names. Kevin explained he has had to unretired names as they have been made valid after they
were flagged to be retired.
Kevin asked users to provide feedback on the Domain Value Change Notification process.

What is the Freshwater Explorer?
The Freshwater Explorer is an
interactive-web based platform that
provides the status of the salt and
mineral content (i.e., freshness) for
freshwater resources across a
network of streams in the
contiguous 48 states.
Freshness, defined as conductivity,
are presented as color-coded
predicted stream reach values and
point (site-specific) measured
values.
Juxtaposing background and
measured conductivity over satellite
imagery lets users see patterns and
otential factors associated with
resh water conditions.

Why was the Freshwater Explorer developed?
	Currently, this type of data is stored in EPA's Water Quality Portal, but is not
very accessible or intuitive in a spatial context.
How was it developed?
	To enable self-sufficiency and greater access, scientists at ORD developed national
datasets that let users independently compare background and measured water
freshness (i.e., conductivity).
	Methods and approaches were published in peer-reviewed journals.
	The national datasets were derived from conductivity data in OWOW's signature
Water Quality Portal. Presently, more than 400 monitoring groups contribute data
to the (WQP) resulting in a spatially and temporally robust dataset.
	The national datasets are presented as an interactive StoryMap.
	OST, OWOW, Regions 3, 5, 6, 9, and 10 were consulted during development or
reviewed the Freshwater Explorer

-------
Who are the primary audiences?

National Water Quality Monitoring Council
Working together for clean water
The 400+ entities that contribute to the
WQP
Federal, state, local agencies, monitoring
groups, NGO's, and industry with a need
to access local water quality data.
Audience requires some degree of
technical knowledge.
Water Quality Portal
The Water Quality Portal (WQP) is a cooperative service sponsored by the United States
Geological Survey (USGS), the Environmental Protection Agency (EPA), and the National Water
Quality Monitoring Council (NWQMC). It serves data collected by over 400 state, federal, tribal,
and local agencies.

What are the anticipated uses and benefits
of the Freshwater Explorer?
 It provides information on the status
of water resources for a network of
streams in the contiguous 48 states
color-coded for predicted and
measured freshness, i.e., low salt and
mineral content.
	Currently, only measured conductivity data is provided, a measurement of
fresh water and water quality that is stored in EPA's Water Quality Portal.
	The web-based story map allows users to quickly access information about
estimated background and measured conductivity.

-------
Observations
Nationally, wetter and higher elevation
portions of the country have naturally fresher
water, particularly in the Northwest, East and
Southeast.
	Measured conductivity in these areas are often
near predicted background conductivity.
In the arid West and agricultural Mid-West,
predicted conductivity is greater.
	Measured conductivity often is greater than
predicted natural conditions owing to various
sources of mineral loadings
Locally, there are a variety of apparent causes
of increased conductivity including road
deicing, marine intrusion, agricultural, urban
and industrial releases and run-off

-------
Changes in Freshness compared to Background
Measured less than or no more than	Measured 500 microS/cm greater
100 microS/cm > predicted Background	than predicted Background
Causes may include: sea water intrusion, drought, loadings, etc.
