Deer Creek Sanitary Relief Phase I Environmental Site Assessment
Location:
St. Louis, Missouri
EDSI conducted a Phase I Environmental Assessment of the area surrounding the proposed sewer alignment utilizing reports from existing databases such as Environmental Data Resources, Inc. (EDR).
The assessment included performing environmental oversight of geotechnical investigation along the alignment of a 100ft deep, 7000 ft long, 20ft diameter tunnel, soil samples screening using a Photo ionization detector (PID), collection of groundwater samples and supervision of temporary piezometer installation. EDSI also performed data compilation, analysis and presented the results and recommendations in a report to the St Louis Metropolitan Sewer District (MSD).
