EWC Ewers Water Consultants Inc.
KARST AQUIFER SPECIALISTS
EWC is a groundwater consulting firm specializing in limestone (karst) aquifer investigations. Our staff regularly engages in aquifer analyses leading to:
- Groundwater monitoring plans
In addition, we undertake geologic and hydrogeologic research studies and design and operate groundwater instrumentation systems.
Among the site investigation, analytical, and technical support services we offer are:
- Groundwater Tracer Studies
- Analysis For Fluorescent Groundwater Tracer Dyes
- Assistance In Tracer Test Design And Analysis
- Groundwater Tracing Supplies And Equipment
- Groundwater Instrumentation.
Tracer studies are essential in preparing karst aquifer protection or remediation strategies. They provide the only unequivocal information regarding the speed and direction of groundwater movement in these aquifers. They are necessary in determining the most appropriate groundwater monitoring points with the least likelihood of confusion from external contamination sources. EWC staff regularly utilize these studies in limestone aquifer investigations relating to hazardous waste facilities, landfills, manufacturing and chemical storage areas, spills, and groundwater withdrawal points. We can provide a complete service from reconnaissance to report, or we can assist your staff in conducting the tracer study.
ANALYSES & TRACING MATERIALS
EWC maintains the most up-to-date analytical instrumentation that is available for the detection and quantification of the fluorescent tracer dyes used in groundwater work. We routinely provide spectrofluorometric documentation of dye concentrations in groundwater at a part per trillion. EWC staff can perform these analyses on water samples and dye detectors delivered to us. In addition, we can provide assistance in designing and interpreting tracer studies and supply the tracers in appropriate quantities, the passive dye detectors, and sampling and monitoring equipment especially designed for detecting and quantifying tracer arrival times and concentrations. This equipment includes dye-concentrating samplers, flow-through fluorometers, and self contained submersible fluorometers.
ASSISTANCE IN TRACER TEST DESIGN & ANALYSIS
EWC regularly acts as a subcontractor to geotechnical and engineering firms as well as government agencies. Frequently we provide guidance and assistance to the staff of these firms and agencies in conducting karst aquifer investigations.
EWC has developed electronic groundwater monitoring packages specifically for karst aquifers. These units reveal the recharge and transfer mechanisms of karst aquifers and are helpful in predicting the arrival times and concentrations of potential contaminants. We can prepare and install these units for your monitoring requirements.
EWC staff has research and consulting experience in 15 states and 10 foreign countries. Our clients include fortune 500 companies; federal, state, and local government agencies; and smaller firms. Key members of the staff include the following.
