There are two other aspects to a Phase 1 that may come into play depending on what is found during the Phase 1 inspection and research. These are Phase 2 and Phase 3. As you might assume Phase 2 and Phase 3 are the more involved aspects of the environmental field. Phase 2 involves testing of the site such as coring into the earth and taking samples of the soil along with testing it to determine what is in the soil. The information during a Phase 2 will determine if the site warrants further investigation and/or to be remediated. If remediation is needed this is Phase 3.
