These graphs display results from CFPUA's regular PFAS monitoring at the Richardson Water Treatment Plant. The first graph displays the total for all compounds analyzed. The second graph displays results for PFPrA, an ultra-short chain PFAS that currently makes up nearly all of the PFAS detected in treated water from Richardson.
The table display results of of the most recent sample for all compounds analyzed.
Use the dropdown menu above the first graph to see historical data for specific compounds. Click the three horizontal lines in the upper-right of the graph to show export options for data currently displayed. You can zoom in on a specific date range by clicking and dragging within the graph to highlight the desired range. Click the three horizontal lines in the upper-right of each graph to show export options for data currently displayed.

Notes: 1) The data in these graphs are results from individual samples. EPA's proposal calls for reporting running averages of sample results for regulatory purposes.
2) Values that are zero may mean the compound was not detected in that sample or that analysis for that compound was not available at the time the sample was taken.
3) Exported csv or Excel files may show "NaN" in some cells. These are blank (no data) cells in the original data.
