Sewer System Alternatives Evaluation for Potential Creswell Area Expansion in Harford County
Final project for ENCE422: Project Cost Accounting and Economics (Fall 2018).
University of Maryland, College Park.This report summarizes the findings of the ENCE422 Fall 2018 class term project. Students were
tasked with evaluating sewer system alternatives for the Creswell area expansion in Harford
County. Student groups were to consider environmental impacts, community/social impacts,
and perform financial analysis for the alternatives they chose to evaluate. This report extracts
information from 14 separate team presentations and synthesizes it around the following
structure; 1. Systems that Utilize Septic Tanks
a. Traditional Septic System
b. Orenco Effluent System
c. Small Diameter Gravity Sewer System
2. System that Do Not Utilize Septic Tanks
a. Traditional Gravity System
b. Vacuum System
c. Grinder Pump SystemHarford Count

Isotope ratios of H, C, and O in CO2 and H2O of the Martian atmosphere
Stable isotope ratios of H, C, and O are powerful indicators of a wide variety of planetary geophysical processes, and for Mars they reveal the record of loss of its atmosphere and subsequent interactions with its surface such as carbonate formation. We report in situ measurements of the isotopic ratios of D/H and O-18/O-16 in water and C-13/C-12, O-18/O-16, O-17/O-16, and (CO)-C-13-O-18/(CO)-C-12-O-16 in carbon dioxide, made in the martian atmosphere at Gale Crater from the Curiosity rover using the Sample Analysis at Mars (SAM)'s tunable laser spectrometer (TLS). Comparison between our measurements in the modern atmosphere and those of martian meteorites such as ALH 84001 implies that the martian reservoirs of CO2 and H2O were largely established similar to 4 billion years ago, but that atmospheric loss or surface interaction may be still ongoing
