Phase II environmental site assessment
A targeted investigation that may include sampling and laboratory analysis to evaluate suspected environmental impacts. The investigation design follows the questions raised by the available evidence.
Why it matters
Phase II is not a single universal sampling package. Locations, media, analytical methods, access, and intended decisions need a defined scope. Testing one area or substance does not demonstrate the absence of every possible environmental condition.
In practice
A project example
A historical tank location may prompt a focused soil or groundwater investigation. The sampling plan should explain what its results can and cannot establish.
