Sampling & Testing

Lambton Public Health works with residents of Lambton County to provide testing and sampling options to prevent or reduce the burden of illness and disease related to human exposure to environmental factors, such as water and insects (ticks and mosquitoes).

Water Sampling & Testing

Our goal is to ensure our water remains safe for everyone to use, whether it is drinking water or recreational water use. Public health inspectors (PHIs) help prevent and reduce water-borne illness related to drinking water by:

  • Working with operators of municipal and small drinking water systems
  • Issuing boil water or drinking water advisories
  • Helping homeowners get private well water tested, interpret water sample results, and provide advice
  • Inspecting public pools, wading pools, spas (hot tubs), etc.
  • Monitoring water quality and safety of public beaches
  • Investigating reports of water-borne illnesses
  • Educating ways to maintain clean and safe waters

Stay safe by:

  • Avoiding recreational waters areas posted as unsafe
  • Checking beach water quality and call the beach info line 519-383-3816 or sign up for text updates and text “BEACH” to 226-909-3003
  • Testing your private well routinely 3-4 times per year, and immediately if the well is flooded

Mosquito Testing & Tick Identification

One hazard of outdoor activity is exposure to insects. Lyme disease is an infection caused by bacteria that can spread to humans through the bite of an infected tick. Not all ticks carry Lyme disease.

Lambton Public Health also monitors the presence of West Nile virus in the community based on the collection and testing of mosquitoes from various locations across Lambton.

Important steps if you find a tick on a person:

Identify the type of tick. Save the tick in a jar screw-top bottle or doubled zip-lock bag and take a photo.

If you are bit by a blacklegged tick from a high-risk area, and it has been attached and feeding for 24 hours or more, Lambton Public Health strongly advises that you speak to a Health Care Provider as soon as possible to see if you meet the criteria for prophylaxis (preventative) treatment.

If you do not have access to your family doctor, there are several walk-in clinics in Lambton County. You can find the list here: walk-in clinic in Lambton County.

If you were not in a high-risk area, continue to identify the tick and monitor for symptoms. Most symptoms of Lyme disease in humans usually appear between three and 30 days after a bite from an infected blacklegged tick. If you experience symptoms, you should speak to a health care provider right away and notify Lambton Public Health – Online Tick Submission ( or Contact Us.
