HAVE A SAMPLING AND ANALYSIS PLAN (SAP)

Transcription

1 THE HOW TO OF SAMPLING, TRANSPORTING, AND DELIVERY HAVE A SAMPLING AND ANALYSIS PLAN (SAP) INCLUDE SAMPLING LOCATIONS NUMBERS AND TYPES OF SAMPLES TO BE COLLECTED QUALITY CONTROL REQUIREMENTS OF THE PROJECT 1

2 THINGS TO CONSIDER WHEN CHOOSING TIME AND SAMPLING SITES CONSIDER THE WEATHER- AVOID COLLECTING SAMPLES WHEN IT IS RAINING OR SNOWING CONSIDER THE LOCATION- AVOID FAUCETS THAT ARE EXCESSIVELY DIRTY, IN NEED OF REPAIR OR CLOSE TO THE GROUND. SAMPLE FROM A COLD WATER FAUCET THAT IS HIGH ENOUGH TO PUT A BOTTLE UNDERNEATH WITHOUT TOUCHING THE FAUCET FREE FROM SCREENS, AERATION DEVICES, HOSES, PURIFICATION DEVICES OR SWIVELS THE GOAL IS TO AVOID CONTAMINATING THE SAMPLE BEFORE SAMPLING CONTACT YOUR CONFIRM DATE OF SAMPLING CONFIRM ANALYSIS REQUIRED PICK UP REQUIRED BOTTLES PICK UP REQUIRED PRESERVATIVES PICK UP CHAIN OF CUSTODY (COC) 2

3 GETTING READY TO SAMPLE OPEN THE FAUCET AND FLUSH FOR A FEW MINUTES WHILE FLUSHING GET BOTTLES READY LABEL TAKE THE CL2 AND PH RECORD ON COC PUT ON GLOVES AND SAFETY GLASSES REDUCE FLOW TO A STEADY STREAM WITHOUT SPLASHING GENERAL SAMPLING FILL SAMPLE BOTTLES MAKING SURE NOT TO TOUCH THE FAUCET. COLLECT ENOUGH SAMPLE ADD PROPER PRESERVATIVE IF NEED RECORD PRESERVATIVE USED, LOT NUMBER AND EXPIRATION ON THE COC PLACE SAMPLES ON ICE COMPLETE COC WITH SITE LOCATION, NAME OF SAMPLER, DATE AND TIME OF COLLECTION AND ANALYSIS REQUESTED GET SAMPLES TO THE AS SOON AS POSSIBLE 3

4 LEAD AND COPPER COMPLIANCE SAMPLING COLLECT SAMPLE FROM COLD FAUCET THAT IS FREE OF WATER SOFTENERS OR POINT OF USE FILTERS DO NOT REMOVE ANY SCREENS OR AERATION DEVICES IF COLLECTING A FIRST FLUSH ALLOW WATER TO SIT UNDISTURBED FOR 6 HOURS BEFORE COLLECTING SAMPLE DO NOT INTENTIONALLY FLUSH BEFORE COLLECTING THE SAMPLE OPEN THE FAUCET AND COLLECT THE FIRST WATER OUT OF THE TAP INTO A WIDE-MOUTH 1 L BOTTLE GET THE SAMPLES TO THE FOR ANALYSIS BIOLOGICAL SAMPLING BOTTLES STERILE 125 TO 150 ML PLASTIC BOTTLES PRESERVATIVE SODIUM THIOSULFATE COOL TO < 10 C (< 50 F) DO NOT FREEZE HOLD TIME IS VERY SHORT DELIVER SAMPLES TO LAB THE DAY OF COLLECTION SAMPLING INSTRUCTIONS --- 4

5 BIOLOGICAL SAMPLING INSTRUCTIONS REMOVE ANY ATTACHMENTS ON THE FAUCET AND FLUSH FOR 5 TO 6 MINUTES AND REDUCE FLOW TO STEADY STREAM WEAR GLOVES AND BREAK THE STERILITY SEAL DO NOT RINSE THE BOTTLE OPEN BOTTLE, HOLDING CAP BY THE EDGE AND DO NOT SET IT DOWN- DO NOT TOUCH THE INSIDE OF THE SAMPLE BOTTLE OR CAP FILL JUST ABOVE THE 100ML LINE WITH COLD WATER TAKING CARE NOT TO TOUCH THE FAUCET AND CAP IMMEDIATELY PLACE ON ICE AND DELIVER TO ON THE SAME DAY THINGS TO AVOID WITH BIOLOGICAL SAMPLING OUTDOOR FAUCETS FAUCETS CONNECTED TO CISTERNS, SOFTENERS, PUMPS, PRESSURE TANKS OR HOT WATER HEATERS NEW PLUMBING AND FIXTURES OR THOSE REPAIRED RECENTLY FAUCETS THAT ALLOW BOTH HOT AND COLD WATER TO COME THROUGH THREADED TAPS SWING SPOUTS FAUCETS POSITIONED CLOSE TO SINK OR GROUND LEAKY FAUCETS 5

6 UNPRESERVED CLASSICAL CHEMISTRY SAMPLING BOTTLES PLASTIC OR GLASS BOTTLE BUT PLASTIC IS PREFERRED PRESERVATIVE PLACE SAMPLE ON ICE 4 C ( 39.2 F) HOLDING TIME IS SHORT DELIVER TO THE THE SAME DAY SAMPLING INSTRUCTIONS RINSE THE BOTTLE WITH THE SAMPLE WATER AND FILL BOTTLE. PLACE ON ICE AND DELIVER TO THE PRESERVED CLASSICAL CHEMISTRY ANALYSIS BOTTLES PLASTIC OR GLASS BOTTLE BUT PLASTIC IS PREFERRED PRESERVATIVE SULFURIC ACID (H2SO4) PH <2 HOLDING TIME 28 DAYS PROTECTION. IF BOTTLES CONTAINS PRESERVATIVE- DO NOT RINSE JUST FILL WITH SAMPLE. OTHERWISE RINSE BOTTLES WITH SAMPLE, FILL AND ADD PRESERVATIVE. PLACE ON ICE AND DELIVER TO THE 6

7 CYANIDE SAMPLING BOTTLES PLASTIC OR GLASS BOTTLE BUT PLASTIC IS PREFERRED PRESERVATIVE 0.6 g ASCORBIC ACID if sample is chlorinated SODIUM HYDROXIDE (NaOH) PH >12 PLACE SAMPLE ON ICE 4 C ( 39.2 F) HOLDING TIME 14 DAYS PROTECTION. IF BOTTLES CONTAINS PRESERVATIVE- DO NOT RINSE JUST FILL WITH SAMPLE. OTHERWISE RINSE BOTTLES WITH SAMPLE, FILL AND ADD PRESERVATIVE. PLACE ON ICE AND DELIVER TO THE METAL ANALYSIS BOTTLES PLASTIC OR GLASS BOTTLE BUT PLASTIC IS PREFERRED PRESERVATIVE NITRIC ACID (HNO3) PH <2 HOLDING TIME 28 DAYS FOR MERCURY, 6 MONTHS FOR OTHER METALS PROTECTION. IF BOTTLES CONTAINS PRESERVATIVE- DO NOT RINSE JUST FILL WITH SAMPLE. OTHERWISE RINSE BOTTLES WITH SAMPLE, FILL AND ADD PRESERVATIVE. PLACE ON ICE AND DELIVER TO THE IF SAMPLES ARE NOT ACID PRESERVED, THEY MUST BE DELIVERED TO WITHIN 14 DAYS OF SAMPLING 7

8 OIL AND GREASE SAMPLING BOTTLES GLASS PICK UP FROM THE PRESERVATIVE HYDROCHLORIC ACID (HCl) HOLDING TIME 28 DAYS PROTECTION. IF BOTTLES CONTAINS PRESERVATIVE- DO NOT RINSE JUST FILL WITH SAMPLE. OTHERWISE RINSE BOTTLES WITH SAMPLE, FILL AND ADD PRESERVATIVE. PLACE ON ICE AND DELIVER TO THE HALOACETIC ACIDS (HAA5s) SAMPLING BOTTLES GLASS BOTTLE MUST BE USED PRESERVATIVE AMMONIUM CHLORIDE, PLACE ON ICE 4 C ( 39.2 F), KEEP SAMPLES ON ICE AND DO NOT FREEZE HOLDING TIME 14 OR 28 DAYS CHECK WITH PROTECTION. IF BOTTLES CONTAINS PRESERVATIVE- DO NOT RINSE JUST FILL WITH SAMPLE. OTHERWISE RINSE BOTTLES WITH SAMPLE, FILL AND ADD PRESERVATIVE. PLACE ON ICE AND DELIVER TO THE 8

9 CHLOROPHYLL SAMPLING BOTTLES PLASTIC BOTTLES ARE PREFERRED PRESERVATIVE PLACE ON ICE 4 C ( 39.2 F), KEEP SAMPLES IN THE DARK HOLDING TIME 48 HOURS SAMPLING INSTRUCTIONS RINSE THE BOTTLE WITH THE SAMPLE WATER AND FILL BOTTLE. PLACE ON ICE AND DELIVER TO THE TOTAL ORGANIC CARBON (TOC) SAMPLING BOTTLES GLASS PRESERVATIVE SULFURIC ACID (H2SO4) PH <2 HOLDING TIME 28 DAYS PROTECTION. IF BOTTLES CONTAINS PRESERVATIVE- DO NOT RINSE JUST FILL WITH SAMPLE. OTHERWISE RINSE BOTTLES WITH SAMPLE, FILL AND ADD PRESERVATIVE. PLACE ON ICE AND DELIVER TO THE 9

10 ORGANIC SAMPLING BOTTLES GLASS BOTTLE MUST BE USED PRESERVATIVE CHECK WITH THE, KEEP ON ICE 4 C ( 39.2 F), DO NOT FREEZE HOLDING TIME GENERALLY SHORT-CHECK WITH THE PROTECTION. IF BOTTLES CONTAINS PRESERVATIVE- DO NOT RINSE JUST FILL WITH SAMPLE. OTHERWISE RINSE BOTTLES WITH SAMPLE, FILL AND ADD PRESERVATIVE. PLACE ON ICE AND DELIVER TO THE 1. NAME DELIVERY TO THE WITH COC 2. ADDRESS 3. SAMPLER 4. DATE & TIME SAMPLE WAS COLLECTED 5. SAMPLE LOCATION 6. ANALYSIS REQUIRED 7. PRESERVATIVE USED 8. SIGNATURE, DATE AND TIME WHEN RELINQUISHED
