REQUIRED CABLE AND FISHWEIGHT


SELECTION OF ANALYTICAL PARAMETERS

CONSIDERING WATER YEAR FROM JUNE TO MAY

PARAMETERS TESTED IN LAB

(AS PER TYPE OF LOCATION)

BASELINE – Ist-30– Balance –20

TREND - Ist-30– Balance –20

TREND/FLUX -Ist-30– Balance –20

RESERVIOR/DAM -Ist-32– Balance –22


CLIPS


SAMPLING FOR DOSAMPLING FOR DO


SAMPLING FOR BACTERIOLOGICAL SAMPLE


WATER TESTING KIT ( FIELD KIT)


FIELD TEST

MEASUREMENT OF FIELD PARAMETERS

COLOUR,ODOUR,TEMPARATURE,EC,pH,& DO ARE FIELD PARAMETERS AND ARE TO BE ANALYSED AS SOON AS SAMPLE IS COLLECTED

MEASUREMENTS OF THESE PARAMETERS CAN BE MADE BY USING FIELD KITS.THIS IS BEST OPTION

ANOTHER OPTION- NEARBY LEVEL-1 LAB

D.O.SAMPLE MUST BE FIXED IMMIDIETLY AFTER COLLECTION OF SAMPLE

TEMPARATURE MUST BE MEASURED AT THE SITE ONLY


FIELD TEST

FILLING AN ID FORM

FIELD TEST

COLOUR CODES

1) LIGHT BROWN

2) BROWN

3) DARK BROWN

4) LIGHT GREEN

5) GREEN

6) DARK GREEN

7) CLEAR

8) OTHER SPECIFY


FIELD TEST

ODOUR CODE

1) ODOUR FREE

2) ROTTEN EGGS

3) BURNT SUGAR

4) SOAPY

5) FISHY

6) SEPTIC

7) AROMATIC

8) CHLORINIOUS

9) ALCOHOLIC

10)UNPLEASENT


FIELD TEST

TEMPARATURE

IN DEGREE CELCIOUS BY USING THERMOMETER

OR

TESTING KIT


FIELD TEST

pH

INDICATES CONCENTRATION OF H AND OH IONS

INDICATES ACIDIC OR ALKALINE NATURE OF WATER

WATER IS ACIDIC WHEN pH < 7

WATER IS ALKALINE WHEN pH > 7

THE pH of DISTILLED WATER IS 7


FIELD TEST

MEASUREMENT OF pH

LITMUS PAPER-

• ACIDIC – BLUE LITMUS PAPER TURNS IN TO

RED

• ALKALINE – RED LITMUS PAPER TURNS IN

TO BLUE

• NUTRAL – NO CHANGE IN ANY PAPER

• BY USING pH PAPER HAVING VALUES OF VARIOUS RANGES 4-11 (UNIVERSAL),1-14,1-10 etc.


FIELD TEST

MEASUREMENT OF pH

-DISC OF pH

10 ml TEST TUBE

UNIVERSEL INDICATOR

pH COMARATOR


FIELD TEST

MEASUREMENT OF pH

ELECTRICAL pH METER OR PENTYPE

1) REQUIRED STOCK SOLUTION

2) BUFFER SOLUTION OF 4,7, & 9.2

3) CALIBRATION OF INSTRUMENT BY USING BUFFER SOLUTION TO TAKE OBSERVATION


FIELD TEST

DISSOLVED OXYGEN

1) GLASS WARES-D.O.BOTTLE,PIPPETES,BURRETS & CONICAL FLASK etc.

2) CHEMICALS( BUFFER SOLUTION)

1) MANGNESE SULPHATE,

2)ALKALI IODIDE AZIDE REAGENT

3) STARCH SOLUTION

4) SODIUM THIOSULPHATE

5) CONC.H2SO4


FIELD TEST

ELECTRICAL CONDUCTIVITY
