Advanced Monitoring
IMPRESS - Field Monitoring
NEIC's Field Monitoring Capabilities

Key Capabilities:

•	Continuous monitoring system
for water quality

•	Provides real-time data reporting
to your computer for pH,
bromide, conductivity, and other
water quality parameters

•	Allows for remote operation

Activation of sensors
Programming for periodic
sample collection
Trigger automatic collection
of samples in response to
specified sensor detections
Take photographs

•	Connects to commercial off-the-
shelf instruments

•	30-day programming capability

Integrated instruments:

•	Bromide sensors, with an
operating range from 25 parts per
billion (ppb) to 1,000 parts per
million (ppm)

•	pH probes, with a pH range from
0 to 14 standard units

•	Conductivity probes, with a
detection range of 0-120,000
micro-Siemens per centimeter

•	YSf multi-parameter water
quality sonde capable of
measuring dissolved oxygen up to
50 ppm, turbidity up to 1,000
nephelometric turbidity units,
and temperature with a range of
23 to 122 degrees Fahrenheit

•	ISCCf automatic composite
sampler with remote control to
program/trigger sample
collection

•	Flow sensors for determining the
presence or absence of flow

•	Camera for photo documentation
of field conditions

Key Personnel:

•	Daren Vanlerberghe - project
manager

Use of this system will significantly reduce the resources required for field sampling
and can also reduce the number of samples for laboratory analysis.

IMPRESS development for field applications:

IMPRESS'S bromide sensor has been field-tested with the Pittsburgh Water and
Sewer Authority and EPA Region 4. NEIC has scheduled future field trials and is
interested in working with other EPA offices to continue the validation of IMPRESS.

In addition, NEIC continues to
evaluate new and existing
sensor technology for
incorporation into IMPRESS,
including additional water
quality parameters such as
nutrients and metals. NEIC is
also working to use the IMPRESS
platform to remotely operate air
sensors, such as sensor pods
(SPods) technology under
development by EPA's Office of
Research and Development.

Integrated Monitoring Platform for
Remote Environmental Sensor
Systems (IMPRESS): IMPRESS is a
modular water sensor platform
developed by the National
Enforcement Investigations Center
(NEIC). IMPRESS provides remote
continuous monitoring of water and
wastewater with real-time wireless
transmission of pollutant
concentration and water quality
parameter data to a computer. It

also allows for remote operation by

EPA, which includes the ability to

start or stop specific sensors or sampling equipment, and to change the sampling
frequency. Another key feature of IMPRESS is the ability to manually or automatically
trigger the collection of samples in response to the data collected by sensors
connected to the platform.
