1
Field Water Chemistry Analysis Equipment Care Test Procedures Results Interpretation Data Reporting
2
Field Chemistry Tests pH Dissolved Oxygen Conductivity Temperature Some things are just best done in person.
3
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.
4
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
5

Interpreting Dissolved Oxygen Results
16
Dissolved Oxygen Temperature
17
Measuring Conductivity
18
Conductivity Meter (and you get a thermometer)
19
1500 1400 1300 1200 1100 1000 900 800 700 600 500 400 300 200 100 0 Conductivity Oil and Gas Well Discharge The higher the number, the poorer the quality. Waste water impact Normal Stream Rain
21
Conductivity Flow
22
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.
23
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!
24
Record Discharge in Cubic Feet Per Second
25
Estimate rainfall in your watershed in quarter inches for the last 24 hours Use Weather Channel, local paper or Toad Gauge
26
ValueObservation NTUs 0Crystal Clear 0 NTUs 1Clear1-3 NTUs 2Cloudy 4-12 NTUs 3Muddy >12 NTUs Turbidity 0-3 point scale
27
Other observations to make Putrescent or otherwise objectionable bottom deposits Oil, scum, and floating debris in amounts that are unsightly Nuisance levels of odor, color, other conditions
28
DO kit pH kit Thermometer Spent chemical waste container Conductivity meter and screwdriver “Blue Book” of instructions Recording forms pencil First Aid Kit Field Chemistry Check List
29
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.
30
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
31
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
32
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
33
Test at the creek! Conduct Field Tests in actual conditions
