19、to provide treatability study test results prior to performing work at the site. Treatability study test results should include the proposed reagents and mix ratios to be used during full scale treatment. The test results submitted should verify that the mix design proposed meets the post-treatment
20、criteria listed in Table 1. Consideration should also be given to the need to monitor off-gas and dust emissions during the treatability study. Detailed information on testing requirements, test methods, detection limits, and off-gas and dust emission testing requirements should be presented in the
21、appropriate section and referenced here.At projects where strict testing protocols are required to adequately determine the effectiveness of the process being tested, the Contractor should be required to provide a “Treatability Study Work Plan“ for approval prior to performing the treatability study
22、.Prior to performing any treatability study, the untreated samples should be tested to verify that they contain the contaminants of concern at high enough concentrations and these contaminants leach at levels which are representative of the materials found on-site. Additional testing may be needed t
23、o verify that physical properties of the samples are also representative of site conditions.The last two sentences of this paragraph should be omitted if a specific method of treatment (in situ or ex-situ) is desired.*Use an in situ pug mill ex-situ _ S/S system that provides a safe, reliable method
24、 to treat contaminated material so that the treated material conforms to paragraph PERFORMANCE REQUIREMENTS. A system or procedure, other than described in this section, may be used if the approved SUBMITTALS demonstrate equivalent capabilities. Such approval does not relieve the Contractor of respo
