priate for this type of waste. As a result, the EPA and the DEQ allowed the application of an alternative method of stabilizing the mercury in the V-9 wastes using SAMMS, a thiol-SAMMS product, for this specific waste stream. The requirement for stabilization was that the final stabilized product would pass the TCLP. The EPA's TCLP test method 1311[4] was designed to determine the mobility of organic and inorganic constituents subject to the Resource Conservation and Recovery Act Our waterMONITOR dataloggers give you a higher level of intelligence. The waterMONITOR series of submersible datalogging level transducers takes "smart transducers" to a new level of intelligence for water resource management. It blends the reliability of our proven line of KPSI level transducers with Pressure Systems' renowned embedded microcomputer expertise. The waterMONITOR delivers high-performance datalogging of well, groundwater, lake, stream, and reservoir levels with these unique features: • Storage of up to 600,000 measurements (level, temperature, time stamp) • Compliance to the demanding accuracy requirements of the USGS Office of Surface Water Be sure to wash thoroughly after handling and follow good industrial hygiene practices. The materials should be stored at temperatures below 140ºF. • Networkable RS-485 interface with SDI-12 protocol • Also available in baroMONITOR configuration for atmospheric pressure compensation (RCRA) standards. The variance approved by the EPA and the DEQ required that the V-9 waste must meet the TCLP target of less than 0.2 mg/L of leachable mercury before it can be considered acceptable for disposal. • Intuitive application software for data management, real-time sampling, and graphic display Preliminary study Due to the hazardous nature of the liquid in the tank, the initial bench experiment used a 25-ml sample from the V-9 tank, diluted with 65 ml of water and tested by TCLP. The adsorption isotherm was used to estimate the required mass of SAMMS to adsorb the mercury in solution to acceptable levels to pass TCLP after stabilization. Testing was conducted on five samples with the following mass loadings of SAMMS: no SAMMS, 0.64-, 1.6-, 4- and 10 times the predicted • Level ranges up to 700 ft. (210m) H2O • Quick-connect cable attachment • Field-replaceable batteries and upgradeable firmware For more details on the waterMONITOR, visit www.PressureSystems.com/550.html, or contact us directly today!
