  • Physical and Geotechnical | Ct Laboratories

    Physical and Geotechnical CT Laboratories has been expanding into Geo Technical and Physical testing for the past several years. We have grown from sieve and grain size analyses to complex grinding and homogenization of soil for multi-incremental sampling projects. Bulk Density Soil bulk density is the ratio of the mass of dry solids to the bulk volume of the soil. The determination usually consists of drying and weighing a known volume of a soil sample. The core method is one method for determining bulk density that can be used with either re-packed or natural cores. EPA Method 310.1 Standard Methods, Method 2320B Methods of Soil Analysis. Part 1. Physical and Mineralogical Properties. 2nd Edition Flashpoint Flashpoint is determined by heating a sample at a slow, constant rate in a closed vessel and introducing a small flame. The flashpoint is the lowest temperature at which the test flame ignites the vapor above the sample. ​ EPA Method 1010A. Grain Size Grain Size is determined by drying and separating a sample with nested sieves of increasingly smaller mesh sizes by shaking on a mechanical shaker. The percentage of pre-weighed soil sample that passes through each sieve is calculated. ASTM C136-84A, ASTM D451-85 - Standard Test Method for Particle Size Analysis of Soils. Specific Gravity Specific Gravity is the ratio of the masses of equal volumes of sludge or soil and distilled water. Specific gravity is determined by comparing the mass of a known volume of sample to the mass of an equal volume of distilled water at 4 degrees C. SM 2710F- 2011 Elutriate Test Preparation The elutriate test procedure is used to predict both dissolved and particle-associated concentration contaminants in confined disposal area effluents. This method simulates contaminant release under confined disposal conditions by combining localized sediment and water, mixing (slurrying), aerating the slurry, settling the slurry and finally decanting the supernatant water into appropriate containers for chemical testing.​ USACE Modified Elutriate Test D-86-4 Illinois EPA Material Analysis for Dredge and Fill Activities (Section 401) Free Liquids A representative amount of waste is placed in a 60 mesh paint filter. If any portion of the material (liquid or otherwise) passes through and drops from the filter within 5 minutes, the material is reported as containing free liquids. EPA Method 9095B. Puck Milling & Multiincremental Sampling Soils and dried and placed in a sieve until debris is removed. The sieved sample is then placed in a puck mill until a fine powder has been achieved. Multiincremental Sampling may occur prior to or after grinding depending on client requests. This procedure was developed in conjunction with the USACE and EPA Method 8330B. Total Organic Carbon (as % organic matter) The organic carbon that is converted into carbon dioxide after oxidation. SM 5310B EPA Method 415.1 EPA Method 9060A Back to Testing Services

  • Reporting & EDDs | Ct Laboratories

    Reporting & EDDs CT Laboratories LLC takes special care to understand the unique needs of our clients to design custom solutions that exceed expectations.

Standard Formats We routinely provide EDDs in a variety of common industry formats, as well as client-specific variations, including: Fixed-length or comma delimited ASCII text Microsoft Excel Worksheet ERPMIS EQUIS SEDD FUDSChem ADR GIS Key Adobe Portable Document Format (PDF) Individual State Program formats ​ Level I? Level IV? Find out what the differences are here . Data Transmission CT Laboratories has several approaches currently in place to transmit electronic data to our clients. ​ These methods include: Transmission of data via Internet email Shipment of files via virus-checked CDs Download via access to our secure FTP website. CT Laboratories has a highly capable information systems (IS) staff that is available to answer questions and assist clients with technical issues. We are keenly aware of the need to protect each client’s data from unauthorized access. CT Laboratories has a number of mechanisms in place to limit both internal and external data access to those parties that are authorized by the client or play a vital role in preparing, processing, or transmitting the data. CT Laboratories also has the ability to encrypt each EDD set using a number of protective schemes, including each application’s native password protection or commercial products, such as WinZip. For more information about our EDD service, contact Information Systems Manager, by telephone at 608.356.2760 Electronic Validation Packages CT Laboratories provides a wide variety of data report formats, including Level IV data validation packages, which contain all QC and raw data necessary for independent review and reconstruction of the analytical results. Our electronic version of the Level IV validation package has been enthusiastically received by our clients, reducing or eliminating the need for shipping and storing multi-ream paper reports. Our electronic package is an original – generated directly from our LIMS, not merely a scanned copy (with the exception of chain of custody and laboratory notebooks). Contact Like what you see?
