Environmental Sampling & Data Collection

Environmental Data Collection & Sampling

Data collected during sampling efforts must provide scientifically accurate information on which clients can base a decision related to injury assessment, risk, or compliance.

EAS is known for rapidly determining the aspects of the problem to be considered to create a sampling design, selecting appropriate sample collection and handling methods, and ensuring the amount and type of data collected provide the right information to the client for decision making. EAS’s sampling and data collection expertise focuses on plants, shellfish, mammals, birds, fish, and invertebrates on land and in coastal and inland waters. EAS has or can easily obtain the permits necessary to perform these collections.
