Sampling Instructions

Sampling instructions for specific analyses are listed at the bottom of this page.  

Click these links for video instructions on sampling or shipping samples.

  1. Clearly label each sample container. 
    Use a permanent marker to indicate the sampling location and the date and time collected.

  2. Use the proper container to collect your sample. 
    Specific sample containers are required for most analyses.  Samples may be rejected if collected in improper containers.  If you are unsure which sample container is required for your project, please contact our lab before sampling.

  3. Do not rinse sample containers. 
    Preservatives necessary to maintain sample integrity may be present.

  4. Refrigerate samples until they reach the lab. 
    Most methods require that samples be held at less than 6°C from collection until analysis.

  5. Submit the sample to the lab within the holding time required for the requested type of analysis.
    Samples may be rejected if not received within the holding time.  Holding times may vary depending on which type of analysis is being requested. Please submit your sample as soon as possible after collection.  Please contact us if you have any questions about the holding time of your sample.

  6. Before submitting your sample to the lab, complete the chain of custody provided. Indicate which analyses are to be performed for each sample.

  7. Call ahead if you need rush processing. Rush fees may apply.  Standard turnaround time for most samples is 10 business days.

  8. Contact us with any questions before sampling. Samples may be rejected if improperly collected or not submitted within the holding time.

Sample Acceptance 

Our office accepts most samples Monday through Friday from 8 am –5 pm.  Please call ahead for bacteriological and wastewater sample acceptance schedules.

Specific sampling instructions are provided below:


CAUTION:
Some sample bottles contain chemical preservatives. These substances may cause injury if spilled in the eyes or on the skin or ingested. In case of a spill, rinse the affected area with large amounts of water and see a doctor immediately. Use of gloves is strongly recommended.

Volatile Organic Chemicals (VOC) in Water

Fill the bottle so that the water ‘domes’ over the opening
Properly filled vials will NOT have an air bubble
  • Vials: 40 mL amber glass VOA
  • Fill the vial under a slow stream of water until it overflows.  The water should be domed at the top.  
  • Gently replace the cap and tighten securely.
    There must be no air bubbles in the vial.  
  • Samples may be rejected if air bubbles are entrapped in the vial.
  • Return the sealed Trip Blank vial with your samples.  Do NOT open it.

Synthetic Organic Chemicals (SOC) in Water

  • Vials: 40 mL clear or amber glass
  • Fill the vial under a slow stream of water until it overflows.  The water should be domed at the top.  
  • Gently replace the cap and tighten securely.
    There must be no air bubbles in the vial.  
  • Samples may be rejected if air bubbles are entrapped in the vial.
  • Bottles: 250 mL, 500 mL, or 1L amber glass
  • Fill the bottle to the neck.  Cap tightly.

Inorganic Chemicals (IOC) in Water (including Lead / Copper and Nitrate)

  • Bottles: 125 mL, 250 mL, 500 mL or 1L HDPE plastic
  • Collect the sample from a kitchen or bathroom cold water faucet.  Remove all screens, strainers or aerators before taking the sample.  Using the cold water tap only, fill the sample bottle completely to the neck.  Cap tightly.
  • Lead/Copper:  Allow the water to stand undisturbed in the pipes for at least 6 hours before collecting the sample.  Click here for more guidance on lead/copper sampling. You will also need to fill out a Chain of Custody to accompany your samples. Select the correct Lead/Copper (Pb/Cu) form for your state on our Chains of Custody page.
  • Nitrate:  Samples must be submitted to the lab within 36 hours of collection.

Microbiology / Coliform Bacteria

Do not wash out the white preservative powder
Fill bottle between the 100 and 120 mL lines

A specially preserved 125 mL sterilized plastic sample bottle is required for this test. Use only a bottle provided by Anatek Labs, Inc. or a health department.

Read the sampling instructions below before beginning to collect samples.

  1. Wash your hands thoroughly with hot, soapy water before opening the bottle.
  2. Select a clean faucet. Avoid collecting from a swivel or hinged faucet, since bacteria regrowth can occur in the cracks.
  3. Remove all screens, strainers or aerators, and allow the water to run for 5 minutes before taking the sample.
  4. Do NOT rinse the bottle! It contains a preservative that may look like a powder or pellet.
  5. Remove and discard the plastic seal from the cap (do NOT leave the seal on the cap). Do not remove the cap from the bottle until just before taking the sample. Do not let the inside surface of the cap or the lip of the bottle touch anything, especially your fingers.
  6. Fill the bottle between the 100mL and the 120mL lines.  Be sure to leave some headspace between the water level and the cap.
  7. Use a permanent marker to clearly label the bottle with the collection date, time and location.
  8. Coliform samples must reach the lab within 30 hours of collection. Samples older than 30 hours cannot be tested.
  9. Keep samples refrigerated or cold (if possible) until you submit them to the lab. Do not let samples freeze.

Soil, Sludge and High-Level Wastes

  • Containers:  Soil and sludge samples are typically collected in two 4-oz. glass jars with Teflon-lined caps.  
    Some solid samples may require specialized containers.
  • Fill the jars completely to eliminate head space.  Cap tightly.  
  • Immediately place sample containers in a refrigerator or cooler with ice until delivered to the lab.

UCMR4

(Click here to view these instructions as a PDF) (Click here to see video sampling instructions)

Contact us with any questions before sampling.  Samples will be rejected if improperly submitted.

  • Clearly label each sample container. Use a permanent marker (Sharpie or similar) to indicate the sampling location and the date and time collected.
  • Use the proper container to collect your sample and do not rinse out any preservatives present. Specific sample containers are required for all UCMR4 analyses. Samples will be rejected if collected in the incorrect container and will require re-sampling. If you have any questions, please contact us before sampling (1-208-883-2839).
  • Refrigerate samples or place samples on ice immediately after sampling prior to shipping to lab. Samples must be submitted to the lab within 48 hours of sampling.  UCMR4 protocols have strict preservation and temperature requirements thus samples must arrive at the laboratory cold (<10oC) and in the correct containers or samples will be rejected.
  • Before submitting your samples to the lab, complete a chain of custody form for each point (EP), distribution system (DS), and water source (SR) .  The additional ‘two bottles per water system’ noted on some tests are collected to allow the laboratory to run matrix spike samples required by UCMR4.
