Camp Equinunk-Blue Ridge, Equinunk, PA

Designed modifications to existing wastewater treatment plant including installation of fine-bubble aeration in existing tankage, a new clarifier adjacent to existing aeration tank, new RAS and WAS piping, and Trojan Technologies UV3000 Ultra-violet light disinfection.

Plumsted Township School District, New Egypt, NJ

Provided process consulting for existing 10,000 gpd extended aeration plant discharging directly to groundwater. Prepared planning and permitting documents for submission to New Jersey Department of Environmental Protection for additional flows from a new high school and adjacent County Library. After performing an evaluation of historic and projected wastewater flows and plant’s capabilities, the existing plant was allowed to accept the increased flow without modification to the plant or the discharge beds. Designed 30,000 gpd equalization tank to accommodate additional flows at rapidly expanding schools by distributing the flows from the 5-day school week over a 7-day period.

Pennsville, NJ

Performed independent engineering evaluation of newly constructed wastewater treatment units at existing plant and identified areas of hydraulic overloading due to undersized orifices, pipes and pumps.

Naugatuck Treatment Company, CT

Obtained existing Naugatuck River Stream Gage Data and coordinated with the USGS to calculate a current 7Q10 for the Naugatuck River. Based on USGS data, Naugatuck Treatment Company (NTC) effluent was computed to be approximately 24% of the total river flow at 7Q10 (assuming design flow for the plant). This was significantly less than the 45% contribution the Connecticut Department of Environmental Protection (CTDEP) had proposed; CTDEP utilized a purely mathematical model designed for undeveloped watersheds which used only subsurface geologic conditions for calculating 7Q10. Identification of the discrepancy between CTDEP computed flows and actual recorded historic river flows facilitated appeal of proposed concentration limits for NTC's discharge permit.

Chester County Solid Waste Authority, PA

Performed project management and engineering services for the following projects:

• Design and construction of leachate treatment plant outfall extension into the Conestoga River which allowed for more readily attainable NPDES permit limits for the treatment plant;
• Design and construction of 6400 gal. sulfuric acid tank at existing leachate treatment plant to replace the existing usage of smaller containers; and,
• Design and construction of flow measurement facilities and three locations within the existing landfill leachate collection system to monitor infiltration through the landfill.

Hatboro Borough Authority, PA

Performed project management duties and on-site activities for the operation of a 60 gpm groundwater treatment system at the Raymark Superfund Site. TCE was the primary contaminant in the soil and groundwater. The treatment system consisted of two wells discharging to two air-stripper units in series. Treated water was discharged to a storm sewer.
