Public Health Laboratory

We provide two services to the general public:

  • Water testing: We test for bacteria in your water.
  • Tick testing: We can identify the species and test for Lyme disease.

Water Testing

If you own a home with a water well, certain agencies may require you to sample and test your water to determine if it is safe to drink.

If you need to take water samples, please follow these steps:

If you have questions on disinfecting your well, please see Environmental Health.

Water Testing Hours

8:00a.m. to 4:00p.m., Monday through Friday. Staff is available to accept samples during lunch hours.

The Lab is closed on County Holidays and will not accept water samples the day before Thanksgiving, (11/27/13) and the day before Christmas (12/24/13).

Tick Testing

If you have been bitten by a tick and wish to have it tested, we can determine the species and test for Lyme disease.

Follow these steps to properly remove a tick, if you have been bitten:

  • Use tweezers to grasp the head of the tick as close to the skin as possible, and pull straight out.
    • Do not squash, burn, smother, or twist ticks.
    • Use gloves, tissue or other barrier if you must use your fingers to remove the tick.
  • Wash your hands and the bite with soap and water after tick removal.
  • Place the tick in a rigid, tightly closed plastic container with a damp paper towel or cotton ball inside.
    • DO NOT place the tick in alcohol, formalin, or other preservatives.
  • Store in a cool place. It is important to keep the tick alive until delivery to the lab.
  • Deliver to the Lab with an Examination Request Form (tick testing can be found under "Parasitology")

A localized reaction or infection can occur where the tick was attached. If redness or pain develops at the bite site, please consult your Physician.

For more information on whether or not you should test a tick for disease, please refer to the California Department of Public Health document, Questions and Answers.

For additional information regarding submitting a tick for testing, please see our Tick Submission flier.

Tick Testing Hours

8:00a.m. to 5:00p.m., Monday through Friday. Staff is available to accept samples during lunch hours.

The Lab is closed on County Holidays.
