Environmental and Effluent Sampling Instructions

SAMPLE COLLECTION | SAMPLE TRANSPORTATION

The following provides sampling instructions for our most commonly requested environmental and effluent analyses. For any other parameters, please contact us for more information.

BOD AND TSS ANALYSES

One 500 mL clean plastic bottle is sufficient for both BOD and TSS analyses.

Please fill bottle completely, leaving no air space, and recap immediately.

FECAL COLIFORM ANALYSES

One 250 mL sterilised container is required per fecal coliform sample.
Please be careful not to introduce contamination when filling the sample container.

NUTRIENT ANALYSES

A minimum of 250 mL in a clean, well-rinsed plastic container is required per sample.
Please be careful not to introduce contamination when filling the sample container.

The sample(s) should arrive at the laboratory in Courtenay within 24 hours of sampling. (Please keep this timeframe in mind if using our Nanaimo Drop-Off Station.)
Samples should be kept cool during transit.
Please supply a completed Requisition Form or include appropriate billing information (name, phone #, fax #, and mailing address), and analyses required.
If this is the first time submitting a sample to North Island Labs for BOD analysis, please advise us of expected levels; this assists us in performing the appropriate dilutions when testing.

Ideally, samples should be delivered to our Nanaimo Drop-Off Station by 11:00 a.m. for same-day shipping to our Courtenay lab.

Due to transportation constraints, our Nanaimo Drop-Off Station can only accept samples until 11:00 a.m. on Fridays.

Wherever possible, please try to take samples right before coming to the Nanaimo Drop-Off Station, to maximize transportation options.
