Homework Assignment:

Homework Assignment: Aquifer analysis Topic: Geochemistry of natural waters, Piper trilinear diagrams Assignment: Class handout.  Fill in the blanks for the five wells that have information missing.  Calculate the equivalents per million (EPM) and % for each ion.  Show your calculations for each well on a separate page.  Plot each unknown water on the blank Piper Trilinear diagram. Due date: TBA Grading: 60 points: Show your work on a separate page, and fill in the chart with EPM and % values for cations and anions in each of the five wells. 40 points: Plot and label the five wells on the blank Piper trilinear diagram.
