2. ARE THERE SOME COMMON DEFICIENCIES I CAN AVOID?
MY LABORATORY…
ARE THERE SOME
COMMON DEFICIENCIES
I CAN AVOID?

3. OF A TYPICAL WASTEWATER LAB?
HOW CAN MY LABORATORY
AVOID SOME
COMMON DEFICIENCIES
FROM AN
ON SITE
LAB EVALUATION
OF A TYPICAL WASTEWATER LAB?

4. “TYPICAL LAB”
HERE MEANS TESTING
BOD
TSS
TOTAL PHOSPHORUS
AMMONIA

5. 1. EQUIPMENT

6. DID I PURCHASE ANY NEW EQUIPMENT SINCE THE LAST ON SITE EVALUATION?

7. IF YES… DO I HAVE A COPY OF THE NEW CALIBRATION PROCEDURE?

8. AM I FOLLOWING THE NEW CALIBRATION PROCEDURE
AM I FOLLOWING THE NEW CALIBRATION PROCEDURE? IF ANSWER IS YES, THEN I AM FINE

9. THE QUESTION IS….WHY NOT?IF
THE ANSWER IS NO…
THE QUESTION IS….WHY NOT?

10. IF THE REASON IS… “BECAUSE SOMEONE TOLD ME I COULD DO IT THAT WAY”
THAT IS NOT A GOOD ENOUGH REASON

11. YOU NEED TO FOLLOW THE NEW OPTICAL DO METER’S MANUFACTURER’S CALIBRATION EXACTLY

12. THE BOTTOM LINE IS… YOU MUST CALIBRATE
AN OPTICAL DO METER and a MEMBRANE DO METER
EVERY DAY THAT THEY ARE USED

13. 2. PERSONNEL

14. ARE ALL THE ANALYSTS THE SAME AS THE LAST “ON SITE” LAB EVALUATION?

15. IF YES…
ASK YOURSELF IF YOU HAVE AN INITIAL DEMONSTRATION OF CAPABILITY OR (IDC) FOR EACH ANALYST?
IF YES...
THEN …
YOUR LAB IS OK

16. IF THE ANSWER IS NO… FOR EVERY YOU MUST HAVE A RECORD ANALYST
OF AN IDC
FOR EVERY
ANALYST
THAT DOES TESTING

17. 3. METHODS

18. DO I HAVE THE CORRECT METHOD FOR THE TEST I ACTUALLY USE?
BOD
TSS
HOT PLATE DIGESTION
TOTAL PHOSPHORUS
AMMONIA ISE

19. THERE IS ONLY ONE APPROVED METHOD IN STANDARD METHODS, APPROVED- FOR EACH OF THESE METHODS THE APPROVED METHOD THAT YOU USE MUST BE IN THE CORRECT FORMAT OTHERWISE-THE COMPUTER WILL NOT BE ABLE TO READ IT
SM 21ST ED 5210 B
SM 5210 B-2001

20. APPROVED METHODS AND THEIR FORMATS
BOD
SM 5210 B-2001
APPROVED METHODS AND THEIR FORMATS

21. APPROVED METHODS AND THEIR FORMATS
TSS
SM 2540 D-1997
APPROVED METHODS AND THEIR FORMATS

22. APPROVED METHODS AND THEIR FORMATS
HOTPLATE
DIGESTION
TOTAL PHOSPHORUS
SM 4500-P E-1999
APPROVED METHODS AND THEIR FORMATS

23. APPROVED METHODS AND THEIR FORMATS
AMMONIA ISE
SM 4500-NH3 D-1997
APPROVED METHODS AND THEIR FORMATS

24. CORRECT ELECTRONIC METHOD FOR BOD?
AM I ORDERING THE
CORRECT ELECTRONIC METHOD FOR BOD?
UNLESS YOU HAVE THE 21ST EDITION OF STANDARD METHODS YOU WILL HAVE TO ORDER ELECTRONIC METHODS
NEW HARD COPIES OF 21ST EDITION ARE
NO LONGER BEING SOLD

25. HACH
TEST N TUBE (TNT) METHODS:
AMMONIA COLORIMETRIC
HACH th ED
PHOSPHORUS
HACH 8190 (Equiv) 5th ED
HACH th ED

26. VALID PHOSPHORUS CALIBRATION CURVES

27. EFFLUENT PHOSPHORUS SAMPLES THAT WERE ABOVE 1 MG/L WERE NOT DILUTED TO BENEATH 1 MG/L THE RESULTS OF1.2, 1.4, 1.6, 1.8, AND 2.0 MG/L NO LONGER FOLLOW A STRAIGHT LINE THESE RESULTS SHOULD HAVE BEEN DILUTED TO 1 MG/L OR LESS
IF I AM USING WWTP OPTIMIZATION TO OBTAIN LOWER PHOSPHORUS, IS MY CALIBRATION CURVE STILL VALID?

28. IF I AM ONLY CALIBRATING PHOSPHORUS UP TO 1 mg/L
THEN I MUST DILUTE MY SAMPLES MORE
BUT MY EFFLUENT RESULTS RANGE FROM 2-3 mg/L

29. ANALOGY :
WOULD I CALIBRATE MY GUN SIGHTS AT 1 YARD
AND THEN,
EXPECT TO HIT A DEER AT A 100 YARDS?

30. NOT IF YOU WANT TO BAG A DEER.
CALIBRATE THE RIFLE AT
15 YARDS AND 100 YARDS

31. MY LAB CAN AVOID SOME
COMMON DEFICIENCIES
IN AN ON SITE LAB EVALUATION
FOR A TYPICAL WASTEWATER LAB
