Environmental Monitoring

PRI will work with you to design and implement sampling plans for pesticides in  water, air, plant materials, food, house dust, and surface residues.

PRI Sampling Services

PRI offers competitive pricing on a variety of sampling services customized to fit your project.

PRI will work with you to design and implement a sampling plan for pesticides in water. We will:

  • Develop a site description
  • Determine the optimum sampling scheme to obtain statistically valid data
  • Document the site and factors affecting transport of pesticides, industrial organics or heavy metals to the water body being sampled
  • Conduct the sampling

Laboratory work is sub-contracted to a certified laboratory. We provide the data in tabular and graphical form and will help you interpret the results in the context of water quality standards/criteria or toxicological standards.

AerialDrift
PRI will work with you to design and implement a sampling plan for airborne pesticides, industrial organics, or heavy metals nearby. We will:
  • Develop a site description
  • Determine the optimum sampling scheme to obtain statistically valid data
  • Document the site and factors affecting airborne transport of pesticides, industrial organics, or heavy metals near the site
  • Conduct the sampling using either low- or high-volume or canister sampling techniques

Laboratory work is sub-contracted to a certified laboratory. For outdoor sampling, real-time weather data are collected during the sampling run at 15 minute intervals. We provide the analytical and weather data in tabular and graphical form and will help you interpret the results in the context of existing air quality standards or toxicological standards.

Concerned about pesticide contamination on your farm or in your flower bed or lawn? Pesticides can become incorporated on plant surfaces and within plant tissues through spray drift onto nearby properties, dispersion of ground treatments, as well as foliar and granular treatments in the nursery. PRI can accommodate the needs of both small and large sampling projects to provide you with the information you need.

  • Sampling kits for small-scale projects are available upon request and can be shipped directly to your door.
  • For larger projects, PRI will determine an optimum sampling scheme of the plant materials of interest to obtain statistically valid data.

Laboratory work is sub-contracted to a certified laboratory, and we assist you with the transport of samples to the lab for testing. Following analysis, we provide you with the data in tabular and graphical form and will help you interpret the results.

PRI will work with you to design and implement a sampling plan for the food of interest. We will:

  • Determine the optimum sampling scheme to obtain statistically valid data
  • Handle the transport of the samples to a certified laboratory for testing
  • Provide the data in tabular and graphical form following testing, and help you interpret the results in the context of legally allowable pesticide residues for the particular food (pesticide tolerances) and anticipated dose based on estimated dietary intake.

House Dust Surface Residue
PRI will work with you to design and implement a sampling plan for pesticides in house dust. We will:
  • Determine the optimum sampling scheme to obtain statistically valid data on the concentrations of pesticides in house dust
  • Document the site and factors affecting the airborne transport of pesticides, industrial organics or heavy metals near the site
  • Conduct the sampling using either low- or high-volume sampling techniques

Laboratory work is sub-contracted to a certified laboratory. We provide the data in tabular and graphical form and will help you interpret the results in the context of potential sources and exposures from house dust.

PRI will work with you to design and implement a sampling plan for pesticide residues on surfaces. We will:
  • Determine the optimum sampling scheme to obtain statistically valid data on pesticide residues on plants, yards, toys, cars, etc. that may have arisen from spray drift of a pesticide onto nearby property or inside a home that has been treated with pesticides
  • Document the site and factors affecting the airborne transport of pesticides, industrial organics or heavy metals near the site
  • Conduct the sampling

Laboratory work is sub-contracted to a certified laboratory. We provide the data in tabular and graphical form and will help you interpret the results in the context of existing drift regulations.
