Phase I & II Environmental Site Assessments

HSW Engineering staff members have completed assessment and remediation projects in Florida for more than 28 years, including more than 800 Environmental Site Assessments (ESAs).  ESAs are conducted in accordance with the most current version of ASTM International (ASTM) Standard Practice for ESA Process (E 1527) and Standard Practice for Limited Environmental Due Diligence: Transaction Screening Process (E 1528).  If environmental concerns are unresolved during the Phase I ESA, or the presence of recognized environmental conditions is suspected, a Phase II ESA may be performed in accordance with the ASTM E 1903 Phase II ESA Processes or based on our extensive knowledge of the site assessment process in Florida.

One of our many project examples includes our Pinellas County work.  The Office of Economic Development selected HSW through a competitive process to perform Phase I and Phase II ESAs in support of its Brownfields Program and US EPA Assessment Grant.  Findings of the Phase I ESAs (and limited Phase II activities) were summarized into clear and concise reports.  HSW also provided recommendations including estimated costs to perform additional site rehabilitation activities.  Additional services were performed at one site to further investigate the findings of the Phase I ESA and manage associated environmental issues including:

  • Subsurface evaluation of buried debris using test pit excavations;
  • A survey of groundwater use / wells in surrounding area;
  • Strategic planning for long-term management of the property; and
  • Meeting with representatives of the client, Pinellas County and local government officials.

HSW maintains several master service contracts with minority / women owned businesses to perform various services ranging from laboratory, drilling, and surveying services.  These contracts are utilized, where possible, to satisfy the requirements of the Brownfield Assessment Grants.
