ALWI is a full-service environmental consulting firm, providing technical and regulatory support to projects involving the subsurface or land discharge of wastewater throughout the Mid-Atlantic region. We possess expertise in technical and field evaluations and related regulatory permitting for individual and community on-site sewage disposal systems. Among other specialty services, we perform percolation and infiltrometer testing and related evaluations of soil and its capability to store and/or transmit water.

Our soils and hydrogeological experts have completed site suitability and groundwater discharge evaluations in both bedrock and in Coastal Plain hydrogeologic settings These projects generally involve classifying subsurface materials (i.e. soils), constructing monitoring wells and piezometers, designing and executing soil infiltration tests, assessing baseline water quality and aquifer hydraulics, and estimating groundwater mounding and nutrient loading potential.

Led by Professional Geologists, Licensed Environmental Health Specialists and Registered Sanitarians, with success we have supported wastewater discharge plans for municipalities, county utilities and other large projects throughout the Mid-Atlantic region. We also support schools, churches, shopping centers, camps and campgrounds, and other projects of more intermediate size.

Our groundwater discharge specialists perform rapid, accurate and cost-effective soil suitability evaluations, double-ring infiltrometer tests, percolation tests and other field programs to support groundwater mounding evaluations and related permit application requirements.
