Package all water samples so they are refrigerated (2-6°C) in a cooler with frozen cold packs.
If you are submitting samples that are testing for only metals and/or fluoride, store and transport them at ambient temperatures.
The Chemistry program will test samples received outside this requirement and the report will include a disclaimer comment.
All samples must arrive at the State Lab with a chain of custody/requisition form and valid form of payment.
If samples are shipped using a commercial carrier like FedEx, UPS, or USPS, follow the carrier-specific shipping liquids instructions. You can find this information on the carrier’s website.
Separate the containers from each other, and the walls of the box, to prevent damage. You can use bubble packaging or corrugated box dividers.
Include an absorbent, like paper towels or cotton balls, to soak up any liquids that may spill. Add packing paper or bubble packaging to fill any empty space to cushion containers during transit.
Seal and label your shipment. Place the label on the top of the package to increase the chances it will be shipped in the preferred orientation.
Water testing samples can be shipped, dropped off at the State Lab, or given to a participating local public health agency for the State Lab courier to pick up. The State Lab courier service does not pick up water samples from residential addresses.
The State lab is closed on state holidays. Drop off samples in person at the lab no later than 3 p.m. on the business day before the holiday, or wait until the following business day to submit the sample. Do not ship water samples the business day before the holiday - the Lab will not be open to receive it.
Dropping off samples at the State Lab
You can drop off samples on the south side of the building Monday through Thursday, 8 a.m. - 5 p.m. and on Fridays, 8 a.m. - 3 p.m. The lab is not open on the weekends or on state holidays. The receiving door is on the south side of the building near the loading dock (indicated by a yellow star on the map below).

We also accept water samples via FedEx and the U.S. Postal Service (USPS). We recommend overnight shipping samples immediately after collection. Your samples may be time sensitive and need to be at the lab within 24 hours after collection. If you ship a cooler you would like returned, include a prepaid self-addressed shipping label.
Follow sample packing instructions to prevent collection bottles from leaking or breaking during transit.
Dropping off samples at a local public health agency
Water samples can also be dropped off at a participating local public health agency where the State Lab courier service can pick up the water sample to transport back to the State Lab. Contact the local public health agency prior to dropping off the sample to make arrangements.
