Shipping Instructions

Our Fresno office is open 7:00 am to 5:00 pm for deliveries. Samples can also be delivered to our Hanford location at 422 N. Douty, Suite H; call for hours. Our field technicians or an independent courier can pick up your samples for a fee.

It is always acceptable to ship samples by mail, UPS, Fed Ex, bus or a private courier; overnight shipment is best.

Soil and Plant Tissue Samples:

• Place soil/plant tissue sample bags in cardboard box and seal. Do not pack tissues samples tightly as they may mold, and never package in plastic. Remember to include a completed Work Request Form and return with sample.

If samples originate outside Fresno County, label your package near your return address with the following information:

• What is inside the package (Soil for Analysis) and from where the sample originates (county and state).
• Due to Fresno County’s Red Fire ant alert, packages without this information may be delayed, confiscated or destroyed by the County Ag Inspectors.

Arrange for samples to arrive Monday through Friday as we are not open on weekends.

Water Samples:

• All water samples should be sent in a cooler with plenty of ice.
• Be sure to use indelible ink on bottle labels as water from melted ice may wash away writing. Enclosing sample bottles in zipped plastic bags helps to prevent sample contamination.
• Be sure to complete and return a Work Request Form with sample.
• Ship sample overnight for arrival Monday through Thursday.

Samples arriving on Friday may not be able to be analyzed in a timely manner. If testing begins after the weekend, then sample may be noncompliant for hold time.
