- SCOPE OF WORK TITLE: In-Situ Water Quality Monitoring System Background The United Stated Environmental Protection Agency?s National Health and Environmental Effect Research Laboratory ? Gulf Ecology Division is engaged research projects in Gulf of Mexico Estuaries that require reliable, continuous measurement of water quality at multiple sites in high fouling, warm-water marine environments during extended deployments with minimal field maintenance. Sites will vary in depth from 1 meter or less up to 30 m. Specifications The vendor shall provide equipment including cables, and other equipment needed to meet the specifications described below. The vendor shall provide eight [8] water quality monitoring instruments, each of which meets the follow requirements. The water quality monitoring equipment shall:? quantify water depth via a pressure sensor in the range of 0 to 100 m with an accuracy of 0.1 m and a resolution of 1 cm.? quantify salinity in a range of 0-40 with a precision of ?0.01.? quantify water temperature in a range of 0 to 35?C with a precision of ?0.01?C or better.? quantify dissolved oxygen in a range of 0 to 120% of saturation concentration with an accuracy of ?0.2 mg/l.? quantify turbidity in the range of 0 to 25 NTU with an accuracy of 0.05 NTU.? quantify chlorophyll-a fluorescence in the range expected when chlorophyll-a concentration is 0 to 50 ?g/L a resolution of 0.05 ?g/L.? quantify colored dissolved organic matter fluorescence in the range of 0 to 500 ppb with a resolution of 0.5 ppb.? have an available external port and data multiplexing capability such that data from up to 2 PAR sensors (see specs below) can be connected to the instrument and the data logged by the instrument platform.? have active and/or passive antifouling measures on all sensors such that the instrument can be deployed in a high fouling estuarine or coastal marine environment for at least 60 days without maintenance and without significant loss of data quality. Active measures may include shutters, wipers, biocide delivery mechanisms, or comparable technologies. Passive measures may include construction with or other application of anti-fouling materials such as copper alloy metals. Documentation of suitable test deployments demonstrating adequate maintenance of data quality in the face of biofouling must be provided.? be designed and built for reliable deployment and use in the marine environment. Examples including the use of rugged, corrosion-resistant materials for instruments and use of durable underwater cables with wet-mateable connections. Vendor should indicate the features of their product that comply with this specification.? be provided with an internal battery or external battery pack capable of powering an autonomous deployment for at least 60 days, contingent upon a reasonable sampling program (e.g., 2 minute sampling interval every 30 minutes).? have the ability to either log data internally (i.e., as an autonomous instrument) or provide data to a host instrument such as buoy system with data telemetry.? have the ability to sample and average results for a defined sample period (e.g., 2 minutes) at a defined sampling interval (e.g., 30 minutes). The vendor shall provide eleven [11] underwater photosynthetically active radiation (PAR) sensors, each meeting the following specifications. The PAR sensors shall:? measure underwater PAR (400-700 nm).? have the ability to log data internally, or transmit the data to the water quality monitoring instrument platforms (above).? have active and/or passive antifouling measures such as shutters or wipers such that the instrument can be deployed in a high fouling estuarine or coastal marine environment for at least 60 days without maintenance and without significant loss of data quality.? be designed and built for reliable deployment and use in the marine environment. Examples including the use of rugged, corrosion-resistant materials for instruments and use of durable underwater cables with wet-mateable connections. Vendor should indicate the features of their product that comply with this specification.? Be provided with appropriate underwater cabling, 2 meters in length, to connect up to 2 PAR sensors to a water quality monitoring instrument (above) The vendor shall supply a total of 2 short (e.g., 3 m) sea cables suitable for connecting the above instruments to a computer in the field or laboratory for the purpose of recovering data and programming deployments. To provide for the secure deployment and recovery of the instruments, the vendor shall also provide two [2] acoustically released pop-up buoys one [1] surface control device and eleven [11] acoustic pinger devices that: ? enable a small vessel operating in waters up to 30 meters in depth to approach the vicinity of water quality sensors (above) deployed on the sea-bed and transmit an acoustic signal to a device attached to the sensors, thereby releasing a float and attached line which may be used to recover the instrument platform. The instrument platform and any attached weight or anchor will be retrieved by hand (i.e., weight load will be light).? are constructed of rugged, corrosion-resistant materials, suitable for extended deployment is salt water and expected to function even it external surfaces are biologically fouled (pop-up buoys)? can remain in stand-by mode and able to respond to a release signal for at least 90 days (pop-up buoys)? Is battery-operated and sufficiently weather-resistant to enable reliable operation on a small boat (e.g. 25 ft), operating in a salt-water environment.? Can be deployed underwater for at least 60 days to provide an intermittent acoustic ping at 25-40 kHz that can be used to locate a water quality instrument in the event that it is moved from the deployment location while unattended. An acoustic locating (listening) device is available and does not need to be provided. Delivery of Equipment All equipment and appropriate manuals and other documentation shall be provided to EPA within 60 days of the date that the vendor is notified that the contract has been awarded. The vendor shall send the equipment to: US Environmental Protection AgencyNational Health and Environmental Effects Research LaboratoryGulf Ecology Division1 Sabine Island DriveGulf Breeze, FL 32561
