- Description
- The U.S. Geological Survey (USGS) intends to award a sole source fixed-price purchase order to Campbell Scientific under the authority of Federal Acquisition Regulation (FAR 13.106-1(b)(1)), Simplified Acquisition Procedures, for eight (8) Sentek Enviroscan water profiling probes and accessories. The USGS requires soil-moisture profiling probes to measure water content with depth at numerous locations down to the soil-bedrock interface to determine differences in water available for aquifer recharge between a native reforestation site and adjacent invasive grassland. This capability is necessary because it provides a minimally invasive means of assessing soil moisture dynamics. Without this piece of equipment and the capability it brings we would have to rely on traditional methods that require excavation which disturbs the medium of interest and change the properties of the very thing we need to investigate. This study has implications for municipal water supply as well as aquatic ecosystems that rely on groundwater discharge. The Water content profiling probes must have the ability to measure water content at 10 cm intervals down to 1 m in a single device. The water content sensors will be used to monitor the vertical movement of water through the soil, which is about 1 m thick. Having sensors every 10 cm allows us to determine the position of the wetting front more accurately than we would be able to with fewer sensors. One of the main goals of our study is to look at differences in water movement within a reforested area and adjacent grassland. The differences may be subtle, so we need to be able to measure that as accurately as possible. The further apart the sensors, the less likely we may be to detect differences. It also must have limited peripheral equipment as the field site we will be working at is high on the leeward slope of Halakala volcano in Hawaii which has very rugged terrain with limited vehicle accessibility; therefore it is essential to keep equipment as minimal as possible as everything must be hand-carried in. The probe must be compatible with the Campbell Scientific CR1000 or CR10X data loggers that we use. It must also have these additional specifications: -Small diameter (< 6 cm) to assure adequate installation in rocky soils -Battery powered -Less than a 10 cm sphere of influence -Continuous real-time monitoring -It must be able to remain in the field for extended periods (1 year or more) -Water content range should be zero to saturation -Temperature range of 0-35 degrees Celsius -It must not use a radiation source -It must not require a cellular network (lack of coverage at site locations) The Enviroscan Soil-Moisture Profiling Probes have unique features which are required to meet the USGS' need. First, any probes we deploy must be compatible with the Campbell Scientific data loggers that we use in the field. The Enviroscan probes are the only probes offered from Campbell Scientific that meet our specifications and that are fully supported by them; which is critical for solving technical problems that often arise in the field setting. The Enviroscan is the only known water profiling probe that has the ability to measure water content at 10 cm intervals down to 1 m in a single device, which is essential in our ability to accurately measure water movement. They are also the only known commercially available profiling probes that do not require additional peripheral equipment to collect data. This allows the system to be more economical and simpler for us to use in the field. The Enviroscan probes make instrumenting the site much more efficient in terms of minimizing soil disturbance and few hours spent on the installation and troubleshooting as Campbell Scientific rents the installation equipment. While there are many resellers who provide the Enviroscan, Campbell Scientific is the only reseller that can support our current fleet of Campbell Scientific data loggers that will be interfacing with the Enviroscan probe. Campbell Scientific is the only vendor that can give us technical support for both the data loggers and the probe while we are in the field. NO SOLICITATION OR REQUEST FOR QUOTE (RFQ) IS AVAILABLE FOR THIS PROCUREMENT. Notwithstanding, any firm that believes it is capable of meeting the USGS' requirement as stated herein may submit a capability statement, proposal, or quotation, which shall be considered by the Agency (FAR 5.207(c)(16)(i)). All questions or comments regarding this procurement shall be addressed in writing to Zachary Buss, at zbuss@usgs.gov. This notice conforms to the requirements in place through FAC 2005-58, Effective 18 May 2012. The North American Industry Classification System (NAICS) Code for this procurement is 334513 - Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables. SBA Size Standard is 500 employees Subject to the Availability of Funds
