Mallison is a professional engineer supporting LDA Engineering’s dedicated team. She has over six years of experience as an environmental engineer, working on wastewater projects for Knoxville Utilities Board, Lenoir City Utilities Board, and Baton Rouge Department of Public Works and accomplishing water quality assessments, watershed delineations, stormwater modeling, and a green infrastructure master plan for various agencies throughout Georgia and East Tennessee. While earning her M.S. in Environmental Engineering, she also worked as the hydraulics lab supervisor and as a graduate research assistant. Her responsibilities have focused on floodplain delineation, field investigations and sampling, large data set manipulation and projection, watershed assessment and protection plans, stormwater pollution prevention plans, basin characterization prior to the rehabilitation and reconstruction of sanitary sewer infrastructure, sanitary sewer rehabilitation and placement, project services during construction, and sanitary sewer maintenance management. She has a passion for working in watershed-based studies, hydraulic modeling, stormwater planning and design, low impact development, and wastewater projects.
As an environmental engineer, Mallison developed initial project planning documents and is currently working on identifying and prioritizing green infrastructure locations that reduce stormwater runoff and combined sewer system overflows.
As a civil engineer, Mallison assisted with developing the framework for this program and currently tracks project schedules and cost, performs QA/QC reviews of stormwater models, and accomplishes design tasks as they arise.
Project Manager Assistant, Knoxville Utilities Board Blockage Abatement Program, Knoxville, Tenn. (2010-2013)
As assistant project manager, Mallison aided in determining the user interface of a computerized maintenance management system (CMMS), created the blockage abatement and lateral inspection process manual, developed criteria for assessing sanitary sewer maintenance schedules, and used project management tools. Mallison also responded to client questions regarding CMMS software and querying asset information.
Project Engineer, Clayton County Water Authority Floodplain Mapping, Clayton County, Ga. (2010-2011)
As a member of a technical team tasked to provide professional engineering services in support of floodplain delineation, Mallison’s main focus was assessing survey data in ArcGIS, modeling river systems in HEC-RAS, and checking output with CHECK-RAS.
Mallison reviewed technical specifications and performed post-installation inspections of structures and equipment for Phase II of the $20 million Lenoir City Wastewater Plant. Upgrades were designed to comply with TDEC to ensure clean waterways and meet strict regulatory requirements. Mallison also obtained and interpreted technical documents to compile an O&M manual for the plant operations staff.
As a design engineer, Mallison assessed the condition and limitations of current water and wastewater infrastructure at 5 air force bases. She evaluated design standards, reviewed specifications, and made water and wastewater infrastructure recommendations.
In her role as field engineer, Mallison collected on-site surface water samples for chemical and bacteriological laboratory analysis to be used for stream quality determination, analyzed and summarized water chemistry and biological monitoring results, and developed watershed and assessment plans in compliance with Metropolitan North Georgia Planning District and Georgia Environmental Protection Division guidelines.
Project Engineer, Knoxville Utilities Board Sewer Rehabilitation Program, Knoxville, Tenn. (2008-2009)
As project engineer for this $530 million 10-year effort, Mallison was tasked with rehabilitating deteriorated sewer infrastructure which included: piping, pump station upgrades, construction of storage basins, and upgrade of existing wastewater treatment plants. Her responsibilities included basin characterizations, results reporting, cost estimation, subcontractor management, scope development, work plan development, design, and record drawing management.
As a project engineer, Mallison performed hydraulic evaluation and created a project definition for the Hooper Storage Pump Station project.
Environmental and Field Engineer, Stormwater Pollution Prevention Plans, Gwinnett County, Ga. (2008)
Mallison visited four water reclamation facilities and evaluated their potential pollutant sources, plant activities, and stormwater pollution structural and non-structural controls. Based on data collected during the field visits, she prepared a stormwater pollution prevention plan to comply with each facility’s National Pollution Discharge Elimination System (NPDES) permit.
Environmental and Field Engineer, Water Quality Assessment of the West Prong of the Little Pigeon River, Gatlinburg, Tenn. (2008)
In her role as an environmental and field engineer Mallison assisted in the assessment of the hydrology and water quality changes which may have resulted from the expansion or removal of the Gatlinburg wastewater plant discharge to the West Prong of the Little Pigeon River.
Environmental and Field Engineer, Work Plan Preparation for Implementation and Management of an Umbrella Mitigation Banking Instrument, Cobb County, Ga. (2008)
Mallison assisted in the development of a work plan to provide a strategy to successfully develop and finalize an Umbrella Mitigation Banking Instrument with the U.S. Army Corps of Engineers. One of the goals of establishing the mitigation bank was to improve and/or preserve the functional aspects of its wetlands and streams.
Environmental Engineer, Work Plan Preparation for Mass Reduction of Ground Water Contamination, Knoxville, Tenn. (2008)
As an environmental engineer, Mallison aided in the development of a work plan proposed to reduce the hazardous constituents mass and volume through the utilization of an In-situ Biostimulation method to promote anaerobic biodegradation in combination with monitored natural attenuation.
Mallison assisted a local watershed task group in the creation and testing of a pilot Ecological Credit Trading Market. The primary objective of the pilot was to examine how credit markets for sediment, nutrients, and other ecosystem values can be used to create opportunities for financial rewards and cost savings. The goal is to drive stakeholders to a set of watershed restoration actions that occur more quickly, in more locations, and are more cost-effective than would be the case without market-based mechanisms.
