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 standard solutions Other field testing equipment is usable if calibrated and documented. Testing strips such as pH paper and “dip strips”are not accepted.
How to count to 10 The ability to differentiate color How to follow step by step instructions The ability to fill a bottle What you need to know
Measuring pH
pH testing kit
pH-Good Between 6-9 Standard Units Acid Range Basic or Alkaline Range
Interpreting pH Results
Measuring Dissolved Oxygen
Dissolved Oxygen testing kit
Dissolved Oxygen Levels 0-4 mg/l poor 4-7 mg/l fair 7-10 mg/l good mg/l excellent over 14 ????? Check your test!
Interpreting Dissolved Oxygen Results
Dissolved Oxygen Temperature
Measuring Conductivity
Conductivity Meter (and you get a thermometer)
Conductivity Oil and Gas Well Discharge The higher the number, the poorer the quality. Waste water impact Normal Stream Rain
Conductivity Flow
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.
Flow Observations Flow 0 = Dry 1 = Ponded 2 = low 3 = Normal 4 = Bank Full 5 = FLOOD! Get to know your creek 0=Dry 4=Bank Full 5=Flood!
Record Discharge in Cubic Feet Per Second
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.
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 Equipment Use
Test at the creek! Conduct Field Tests in actual conditions
