.: Overview

Burge Environmental Inc., introduces several different automated water monitoring systems for the determination of the following contaminants in drinking, natural and process waters. We have designed, fabricated and tested automated instrumentation for the following environmental contaminants (in water) with the method of detection listed below:


Method of Detection




Optrode, Colorimetric


Optrode, Colorimetric

Carbon Tetrachloride

Optrode, Colorimetric

Hexavalent Chromium



Mini-column sensor, scintillation


Mini-column, scintillation

Uranium (uranyl ion)



The systems were developed in association with two national laboratories (Pacific Northwest and Lawrence-Livermore) using SBIR and STTR funding from the Department of Energy and the Department of Defense

The instrumentation is designed to allow for interface of the primary sensor, auxiliary sensor(s) and sampling methods using a “plug and play” mode of operation.  The user selects the sensors, sampling techniques and communication methods, plugs the component into the correct slot and selects the appropriate software on the computer program.  The instrument is capable of operating in the appropriate mode (signal acquisition and sample collection) with the sensors and sampling methods.

The instrument is capable of being powered by 110-volts in a laboratory environment, or solar cells (12-volts) at remote locations. 

The instrumentation automatically performs the following operations:

  • Sample collection
  • Sample analysis
  • Error trapping and self-diagnosis of operational problems
  • Self-calibration  (calibration curve, or method of standard additions)
  • Waste segregation (to reduce the amount of hazardous waste to be disposed)
  • Date reduction (data transposed onto Excel spread sheets)
  • Data transfer (data transferred directly to a user, and/or delivered to a website for real-time modeling of the data into visual graphics)

The instrumentation was designed for either deployment in industrial environments or at remote locations.  All the systems have common electronic boards, housings and components.  There are many aspects of the firmware and software that are common to all instruments.  All systems are capable of communicating with either radio-hopping telemetry or phones (landline or cellular)


.: Auxiliary Sensors

  • Conductivity (temperature corrected)
  • pH (temperature corrected)
  • ORP
  • Ion-specific electrode (nitrate, etc.)
  • Temperature
  • Water levels in wells (up to four wells)
  • Water pressure

Therefore, the user may monitor for several chemical and physical parameters from one instrument.  This enables the user to measure the concentration of the primary analyte and characterize the chemical and physical environment of the analyte in the water sample.  The monitoring system has the capability of acquiring samples using any of the sampling methods listed below:

Type of Sampling Method
Number of Sampling Locations
Examples of Sample Sources
Peristaltic Pump
Surface water, industrial water, groundwater (<25 feet in depth)
Electrical Centrifugal Pump
Groundwater (0 to 100 feet in depth)
Bladder Pump
Groundwater ((0 to 200 feet in depth)
Burge Sampler
Groundwater (>100 feet in depth)
Pressurized Valves
4 to 8
Industrial and water treatment plants

.: Communication Options

The automated instrument has a small microprocessor capable of performing all the operational programs (sampling, analysis, waste disposal, etc.).  The microprocessor interfaces with the user using a program loaded onto a laptop computer.  Communications between the microprocessor on the instrument and the computer can be performed in several ways listed below.  The communication options allow the deployment of the instrument at remote locations.

Method of Communication
RS-232 Direct Connection of the Analytical Unit to the computer 100 feet
Frequency hopping radio telemetry Remote connection of the analytical unit to the computer Field: 10 to 12 miles line of sight

Treatment Plants: 200 yards
Phone Modem (land line or cellular) Remote connection Almost unlimited where service is available


.: Field Deployment

unit_riverThe monitoring systems may be deployed in remote locations for acquiring data from monitoring wells, surface water sources and water treatment projects (barrier walls, reagent injections).  The systems are capable of monitoring four different sampling locations (wells, surface waters) using a variety of sampling methods (peristaltic pumps, electrical pumps, bladder pumps).  The monitoring system may use solar cells or wind turbine for power generation if no power is available. 

The monitoring system is reconfigured to allow for the insertion in an 8-inch well casing located below the field deployment box.  This protects the analytical unit while providing temperature control.

The automated instrument has the capability of communicating with the user using telemetry with a range of 8 to 12 miles line of sight, and cellular modems.  An operational example was the hexavalent chromium system located along the Columbia River in the State of Washington operated by a user from a location in Tempe, Arizona.

The field deployment box has been used for several years at locations in California and Washington.

.: Industrial Environments

The monitoring systems are reconfigured for deployment in a metal box for mounting on the wall of an industrial facility.  The deployment allows the user to sample from 4 to 8 different locations within the treatment facility.  This makes it ideal in tracking the efficiency of a treatment plant at various stages of the operation of the treatment process.  The system has been used in monitoring for breakthrough in activated carbon treatment systems to reduce to operational cost of the process.

The system can be installed in an industrial environment and communicate with the user using telemetry, thereby, eliminating the need to run cables within the industrial facility.
