A Groundwater Professional is defined by Chapter 567-134 as “a person who provides subsurface soil contamination and groundwater consulting services, or who contracts to perform or who supervises remediation or corrective action services at leaking underground storage tank sites.”  These services and activities must be provided by or directly supervised by a certified groundwater professional.  All reports submitted to the Iowa DNR must be signed by the Certified Groundwater Professional supervising the work at the site.
