7. DATA VALIDATION 1)DATA VALIDATION – SWDES ONLY 2) NO ACCESS TO HYMOS FOR W.Q.DATA 3) VALIDATION IS ON THE BASIS OF PARAMETERS CO-RELATION BETWEEN pH, D.O. BOD,COD etc

8. DATA VALIDATION 1)SAMPLING TECHNIQUES 2) FIELD DETERMINATION 3) PRESEVATION IN FIELD 4) PEROD OF SAMPLE RECEIPT TO LAB 5) TREATMENT IN LAB DATA VALIDATION FACTORS AFFECTING W.Q.VALIDATION

9. 6) MISSING PARAMETER 7) PARAMETERS IN CUSTOMISED MENU ( LIKE TURBIDITY ) 8) SHORT INFORMATION ENTERED IN ID FORM & ANALYSIS RESULTS DATA VALIDATION FACTORS AFFECTING W.Q.VALIDATION DATA VALIDATION

10. MINIMUM & MAXIMUM VALUES SERVE AS A FIRST VALIDATION DATA VALIDATION FIRST VALIDATION

14. A) CATIONS – Ca, Mg, Na, K B)ANIONS – Cl, SO4, CO2, HCO2, NO2, NO3 C) TOTAL CATIONS – D) TOTAL ANIONS – DATA VALIDATION DATA REQUIRED

15. 1) ION BALANCE :- C – D / C + D 2) ION BALANCE :- Na / Cl 3) EC BALANCE :- TDS / EC 4) CARBON BALANCE :- COD / BOD 5) CO3 BALANCE :- IF pH < 8.3 PHEN ALKALINITY = 0? DATA VALIDATION

16. DATA VERIFICATION CRITERIA 1)ION BALANCE < 0.1 2) ION BALANCE = 0.8 – 1.2 3) EC BALANCE = 0.55 – 0.9 4) CARBON BALANCE – 1-10 5) CO3 BALANCE = YES ( OK ) DATA VALIDATION

17. 1)Checked By – Here the responsible person or the head of Laboratory,should put his name or initials after checking the outcome of the validation 2) Remarks :- In this field the person who has checked the data may put some remarks i.e. to explain why a sample did not pass a validation check. DATA VALIDATION

18. 1)If sample did not pass the validation check then it is required to reanalyze the sample( If sufficient quantity of collected Sample is available) otherwise reject the sample and collect new sample. SOME KEY POINTS DATA VALIDATION

19. 2) In such cases it is necessary to see the following aspects i) Check manuscript copy of data ii) Validation should be done manually before entering the data & do not allow to enter the data in the computer before satisfactory manual validation SOME KEY POINTS DATA VALIDATION

20. iii) Check ERRORS in instruments, Calculations, Check chemist register, Life of stock solution, Type of distilled water, Calibration of instruments, Analytical procedure adopted DATA VALIDATION SOME KEY POINTS
