Storm Water Quality Management Plan, or SWQMP, takes over where construction ends. Larger cities, such as Houston, Dallas, Fort Worth, San Antonio, and Austin require a SWQMP plan and permit to properly control runoff from sites. Most recognizable is the detention and retention ponds. These must be inspected regularly and maintained in order for permits …
Toxicity Characteristic Leaching Procedure (TCLP)
A method of analysis for metals in samples taken as part of a lead abatement and is used to determine disposal method of the waste. It is a chemical analysis process used to determine whether there are hazardous elements present in a waste. The test involves a simulation of leaching through a landfill and can …
Transmission Electron Microscopy (TEM)
A method of analyzing air samples for asbestos. Samples are collected during abatement and analysis is completed by an accredited laboratory (NVLAP). An electron source at the top of the microscope emits electrons that travel through a vacuum in the column of the microscope. Electromagnetic lenses are used to focus the electrons into a very …
X-Ray Fluorescence (XRF)
A non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the chemistry of a sample by measuring the fluorescent (or secondary) X-ray emitted from a sample when it is excited by a primary X-ray source. Each of the elements present in a sample produces a set of characteristic fluorescent X-rays …
