AES is highly experienced with completing NPDES Phase II stormwater infiltration studies at various land development sites in Pennsylvania. Although the regulations requiring such studies are recent, the field and office techniques and experiences necessary to successfully develop and implement stormwater infiltration studies are not new. The staff and scientists at AES have been able to adapt their knowledge and expertise in the areas of soils, geology, groundwater, and surfacewater in order to design and implement pertinent and economical stormwater infiltration studies.

Our approach to these projects follows our tried and true business ethic - listening to our client's needs. After meeting with our clients and obtaining details regarding desired land use expectations, drawings, and related municipal ordinance requirements, the scientists at AES develop a site-specific work plan focused on meeting the needs of our client and addressing the pertinent regulations.

Typically our investigations involve the identification and collection of important pieces of site information necessary to characterize the site, assess the viability of onsite stormwater infiltration, and provide the data necessary for site engineers and architects to appropriately design the stormwater infiltration areas.

To obtain the necessary information on site characteristics, AES typically employs a combination of several proven field techniques, including: Surface Geophysics, Hollow-stem Auger, or GeoProbe® Soil Drilling; Cone Penetrometer remove this word “Technology” Soil Drilling, Backhoe Test Excavations, Soil Percolation/Infiltration Test Wells. The data, conclusions, and recommendations drawn from these studies has proven to be cost-effective and defensible at the local, County, and State government levels. An important factor to contain costs and to ultimately keep a project moving towards completion.
