Heterotrophic Plate Count

How it Works

After you purchase a kit on our store,

We will ship the CARO Kit to you via express shipping. In the CARO Kit, you’ll receive the sampling containers, a sheet to show you how to sample, as well as a chain of custody form (COC). The COC form is a standard lab procedure to get the correct information from you.

Once you sample, it’s advised to get the samples back to us ASAP. You can do this by getting that CARO Kit to a post office or courier and send it back to one of our locations. Certain tests like Microbiology (found in most drinkability packages) have a sample holding time of only 24 hours, so it’s vital to get the containers in transit right away.

So we’ve received your samples, allow 5 – 7 business days for us to analyze them and produce the reports for you. We will email the report to you when it’s ready. Every result’s turnaround time (TAT) will be started on the delivery of filled bottles back to the laboratory.

Internal rushes are possible for non-micobiology tests. Either use the Turnaround Time add on, or make a custom inquiry via the contact us webpage or on the phone.

Does not include sampling safety equipment as what is required depends on various circumstances. Please contact a local environmental consultant if you have questions or concerns about safely sampling. CARO provides testing services only, no sampling services.
