SCOPE OF REQUIREMENT

STATEMENT OF REQUIREMENT

WATER QUALITY SONDES

US ARMY CORPS OF ENGINEERS

ALBUQUERQUE DISTRICT

1. SPECIFICATIONS

A. Water quality sonde: The Contractor shall provide thirteen (13) multi-parameter sondes compatible with YSI EXO sondes, sensors, field cable, and handheld computer. Each sonde shall accommodate a payload of four (4) sensor ports and one (1) central wiper port. Features and specification are as follows:

i. The sonde shall be capable of operating in water depths up to 820 feet (250m) and temperatures ranging from 23° to 122°F ( -5- 50°C).

ii. The sonde shall not exceed 3.00 inches (7.62 cm) in diameter, 23.1 in. (58.67 cm) in length, and 4.41 lbs. (2.0 kg) in weight, with a full payload of 4 probes, 1 wiper, and a probe guard installed.

iii. The sonde shall be a platform with universal ports that can accommodate a variety of sensors, which can be used or reconfigured at any time by the end user in the field. Similarly, the sensors shall have hermaphroditic wet-mateable connectors, allowing them to be plugged interchangeably into any sensor port.

iv. The sonde shall be designed to withstand the harsh conditions of field use by using rugged materials, including Titanium, laser-welded probe housings to resist leaks; wet-mateable connectors that resist corrosion; impact-resistant and chemical-resistant Xenoy polymer reinforced housing; and sapphire glass on optical sensor windows.

v. The sonde shall be equipped with built-in Bluetooth wireless technology for cable-free communications when calibrating, communicating and downloading data (512 MB total memory). An internal magnetic switch and external activation key for wireless control of the Bluetooth radio shall be included. The sonde shall be capable of connecting to field-replaceable sensors that measure dissolved oxygen (DO), conductivity, temperature, pH, ORP, turbidity, chlorophyll/blue-green total algae, fluorescent dissolved organic matter (fDOM) and central wiper. The sensors shall be capable of being removed without opening the sonde or exposing the internal electronics to the environment.

vi. The sonde shall provide low-power consumption for extended deployments and must be able to measure Temperature, conductivity, depth, pH or Turbidity and Optical DO for duration of 90 days at a 15-minute sampling interval.

vii. The sonde shall have an internal depth sensor, non-vented, 0-10 meter depth.

viii. The sonde shall include a central wiper port that is capable of wiping all sensors listed in

Section 1B.

B. Sonde Sensors and central wiper: Continuous water quality sensors compatible with YSI EXO sondes currently being used by the Albuquerque District. The sensors shall measure the parameters below. All sensors must be “smart” and store all calibration data internally to the sensor. Sensors shall be able to be swapped from one sonde to another or from one sonde port to another without recalibration. The Contractor shall provide sensors (see quantities below) for each of the following parameters that meet or exceed the features and specification below:

i. Optical DO sensor: The Contractor shall provide thirteen (13) sensors that employs the Luminescent “Life Time” DO measurement technique. The sensor membrane must be field replaceable component that does not require the use of tools. The sensor shall be able to be calibrated with a one-point (saturated air or water) or a two-point (zero DO and saturated air or water) oxygen calibration.

ii. Turbidity sensor: The Contractor shall provide thirteen (13) sensors capable of measuring turbidity with a Nephlometric type sensor capable of measuring turbidity from 0-4000 NTU.

The sensor will have an accuracy of +/- 2% of reading or 0.3 NTUs (whichever is greater) in AMCO-AEPA Polymer standards from 0-999 NTU and an accuracy of +/- 5% of reading from 1000-4000 NTU.

iii. Wiped Conductivity and temperature sensor: The Contractor shall provide fifteen (15) sensors capable of measuring temperature using a NIST-traceable calibrated thermistor in the range of -5 to 50 degrees C with an accuracy of +/- 0.2 degrees C and a resolution of 0.001 degrees C from -5 to 50 degrees C. Each temperature sensor must include a factory calibration/NIST reference sheet. The instrument shall be capable of measuring conductivity using a four-electrode cell in the range of 0-100 mS/cm with an accuracy of +/- 1% or 0.002 mS/cm and a resolution of 0.0001 to 0.01 mS/cm. The instrument shall be capable of measuring salinity in the range of 0 to 70 ppt with an accuracy of +/- 2% or 0.2ppt with a resolution of 0.01 ppt.

Additionally, the cell design should prevent bubbles from settling on electrodes and interfering with measurements. The conductivity sensor must be a linear device requiring only a single-point calibration. It shall be compatible with a central wiper system and spacer kit to prevent biofouling.

iv. Ungarded pH sensor: The Contractor shall provide thirteen (13) sensors that are able to measure to spec across all ionic strength waters. The pH sensor will be equipped with an internal amplifier to improve signal response and stability and utilize a replaceable sensor head that can be field replaced at minimal cost.

v. Central wiper: The Contractor shall provide thirteen (13) central wipers that keep the payload sensor faces clean during long-term deployments.

C. Sonde Accessories:

i. Six (6) 15-meter EXO compatible flying lead cables.

ii. Six (6) 20-meter EXO compatible flying lead cables.
