4 WATER QUALITY DATA ENTRY DATA VALIDATION S.K.KSHIRSAGAR

5 DATA RECORD A)FIELD TESTS B) GENERAL C) NUTRIENTS D) ORGANIC MATTER E) ALKALINITY

6 F) HARDNESS G) MAJOR IONS H) OTHER INORGANIC I)COLIFORMS J) BIOLOGICAL Data Record DATA RECORD

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

11 DATA VALIDATION UWL & LWL PROVIDED IN THE SOFTWARE TO WARN THE USER SECOND VALIDATION DATA VALIDATION

12 UWL & LWL UWL < or = MAX LWL > or = MIN PREVENT DATA ENTRY/ BUT DISPLAY WARNING SYMBOL SECOND VALIDATION DATA VALIDATION

13 LOD :- LIMIT OF DETECTION USED ONLY FOR VALIDATION PURPOSE IN CASE OF TRACE METALS AND TRACE ORGANICS VALUE < LOD ( Alt-t) DATA VALIDATION THIRD 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 – ) 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

21 Adding Customized Parameters TURBIDITY

22 Adding Customized Parameters is a part of Validation ( ie,Missing Parameter in Data Entry) Water Quality Data Entry in SWDES

23 Adding Customized Parameters STEPS

24 1)Open Option “Laboratory Information”

25 Select Laboratory

26 Select “ General Parameter”Option

27 Select “ General Parameter”Option & Select Desire Parameter

28 “Turbidity” is Selected

29 Open Menu”Sample Data Entry and Validation register

30 Select Menu” Customized Parameters”

31 Parameter TURBIDITY is Selected

32 ENTER THE RESULTS OF TURBIDITY IN THE CUSTOMISED PARAMETER MENU
