Our groundwater modeling services include the following :

 

· On-site supervision of monitoring well installation, including soil sample collection, completion of boring logs and well installation diagrams. Utilization of existing groundwater monitoring wells where possible.

· Collection of groundwater samples from the wells in accordance with DEP and EPA guidelines. Submittal of selected samples for laboratory analysis, and review of the analytical data.

· Determination of aquifer hydrologic parameters through the use of slug tests and/or pumping tests.

· Creation and calibration of a 2D or 3D groundwater flow model typically using Visual MODFLOW.  Models are as detailed as necessary to address the Site situation and proposed alterations.   

· For proposed septic systems under Title V (MA), the concentration of nitrates at the downgradient property line and the height of the groundwater mound under the system are the most common conditions modeled.

· Hydrogeologic Report preparation documenting the conduct and findings of the investigation and modeling efforts in support of a groundwater discharge permit.

 

 

Text Box: New England Environmental, Inc. (NEE) has conducted numerous groundwater modeling projects at various residential and commercial properties.  In this project, NEE was hired to create a groundwater flow model to predict the height of the mounds under two proposed 12,000 gal./day septic leach fields, and to predict the reaction of natural ecosystems to the placement of these leach fields.
