 Environmental
studies and assessments usually involve an element of identifying
sinks, sources, pathways and fate of dissolved and particulate
contaminants, pathogens, and water. ETS' Tracer
technology and complementary scientific services have
the unique ability to trace target species through a range
of environments. Multiple contaminant pathways can be monitored
simultaneously using particulate, fluid and bacteriological
tracers with our detection technology.

Freshwater
|
| |
|
 ETS
have gained extensive experience of freshwater Tracer studies
throughout the UK and the rest of the world. These studies
are often used for model validation, pollution planning strategies,
identification of diffuse pathways and hydrodynamic studies.
Our capabilities include:
|
 |
Time of travel for Urban Pollution Management (UPM).
|
|
Pollution incident assessments for emergency planning.
|
|
Validation of water quality models.
|
|
Environmental Impact Assessment (EIA) of dredging activities.
|
|
EIA of effluent discharges in rivers and inland waterways.
|
|
Hydraulics and sediment studies of lakes and reservoirs.
|
|
Assessments of water quality, eutrophication, turnover,
short-circuiting and residence times.
|
|
Diffuse Pollution pathway studies.
|
|
Combined Sewer Overflow (CSO) and Outfall
Impact Assessments.
|
|
Urban run-off studies.

Groundwater & Leachate
|
| |
|
 Groundwater
protection and identification of pollutant pathways into aquifers
and boreholes are essential for ensuring a safe water supply
worldwide. Our range of non-toxic Tracers and versatile detection
technology allows these sources and pathways to be identified
and quantified, enabling focused remediation and mitigation
strategies to be implemented. Our capabilities include:
|
| |
|
Identification of primary contaminant pathways.
|
|
Validation of groundwater vulnerability maps.
|
|
Contaminant Infiltration studies.
|
|
Identification of contaminant pathways in
groundwater and boreholes from landfill leachate.
|
|
Residence Time of Mine Adit Systems.
|
|
Monitoring of diffuse Agricultural pollution.
|
|
| |
|
Fisheries, Aquaculture and Shellfishery
|
| |
|
 Our
extensive marine capabilities
support our work in these environmentally sensitive industries
both in the UK and abroad. ETS' Tracer particles have been
sampled directly from the gut, water column and sediment bed
to determine fate and accumulation of pollutants within various
marine organisms, studies include:
|
|
Dispersal studies of fish eggs, algal tides and larvae.
|
|
Impact on shellfishery and fisheries due to dredging
activities and outfall discharges.
|
|
| |
|
Atmospheric
|
| |
|
 Particulate
emissions from industry and vehicles have the potential to
compromise local air quality. Due to the nature of atmospheric
emissions it is often very difficult to attribute the origin
of the emissions. ETS Tracer technology allows the labelling
and monitoring of multiple sources of particulate emissions
for various applications including:
|
|
Monitoring movement, fate and accumulation of atmospheric
particulate.
|
|
Aeolian (wind-driven) transport studies investigating
environmental changes at sensitive sites.
|
|
Legislative cases.
|
|
Drift eliminator efficiency for cooling towers.
|
|
Harmful atmospheric biological release simulation.
|
|
|
ETS are investigating new atmospheric applications and detection
methods for Tracer Technology and are currently considering
partners/licensees to help develop and promote Tracing worldwide.
