Field Water Chemistry Analysis • Equipment Care • Test Procedures • Results Interpretation • Data Reporting
Field Chemistry Tests • pH • Dissolved Oxygen • Conductivity • Temperature • Some things are just • best done in person.
Field Chemistry Equipment Lamotte Brand Testing Kits Alcohol or mineral spirit thermometers Conductivity/TDS Meters (calibrated) pH meters calibrated with 4-7-10 standard solutions Other field testing equipment is usable if calibrated and documented. Testing strips such as pH paper and “dip strips”are not accepted.

Field Observations • Flow • 0-5 point scale • 24 hour rainfall • In inches • Turbidity • 0-3 point scale • Some things are just • best done in person.
0=Dry • Flow Observations • Flow • 0 = Dry • 1 = Ponded • 2 = low • 3 = Normal • 4 = Bank Full • 5 = FLOOD! • Get to know your creek 4=Bank Full 5=Flood!
Estimate rainfall in your watershed in quarter inches for the last 24 hours Use Weather Channel, local paper or Toad Gauge

Equipment Use Equipment is “Loaned” to you for the duration of the project. Please return field kits to your area coordinator or sampling event coordinator if you “retire” from the project.
Equipment Use Kits have enough chemical for 50 tests! (use them all you want!) Store in a cool, dry place. NOT a hot car or freezing garage! Chemicals should be replaced every two years. Should you need replacement chemicals or glassware before then, let us know.
Equipment Use There are hazardous chemicals in these kits! DO Test uses a strong alkali (like bleach) pH test chemical is flammable Read Material Safety Data Sheets for handling and Disposal Instructions Use plastic spent chemical waste container at stream Dispose of properly at home.
Equipment Use • We request that you Run D.O., Temp & pH • test every field visit or sampling event. • Feel free to use them more frequently • For monthly or bi-weekly testing • For testing other resources • For educational demonstrations
Test at the creek! Conduct Field Tests in actual conditions
