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

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

DATA REQUIRED

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

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

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

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

SOME KEY POINTS

DATA VALIDATION

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

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

Adding Customized Parameters

TURBIDITY

Adding Customized Parameters is a part of Validation

( ie,Missing Parameter in Data Entry)

Water Quality Data Entry in SWDES

Adding Customized Parameters

STEPS

1)Open Option “Laboratory Information”

Select Laboratory

Select “ General Parameter”Option

Select “ General Parameter”Option & Select Desire Parameter

“Turbidity” is Selected

Open Menu”Sample Data Entry and Validation register

Select Menu” Customized Parameters”

Parameter TURBIDITY is Selected
