Lead-Based Paint Inspection and Specifications
Painted Surfaces
RI Analytical has the qualifications to conduct extensive lead inspections. Representative painted surfaces throughout the project site are visually evaluated, and select areas are then tested using either onsite X-ray fluorescence (XRF) equipment or laboratory-based Indctively Coupled Plasma (ICP ).
Soil Sampling
In addition, soil samples from areas surrounding the project structures may be collected and analyzed. A lead report will be prepared to address any environmental lead hazards identified during the inspection and sample analysis work. The report details information such as the conditions of the painted surfaces, the dates of inspection and all analyses, detection methods used as well as a table of the actual lead test results.
Lead-Hazard Work Specifications
This information is then used to prepare written lead-hazard work specifications that will describe details such as the scope of work, bid documents, procedures for performing the work, strategies for the collection of additional samples for analysis, insurance requirements, contractor submittals, health & safety specifications, disposal requirements and monitoring procedures. The client's existing project drawings may be annotated to indicate the location of lead hazards. If requested, R. I. Analytical Laboratories can also assist you with the evaluation of the various remediation contractors' bids.
Indoor Air Quality
Direct Reading Field Surveys
General air quality conditions can be characterized using field-portable, direct reading devices, each specifically calibrated to measure levels of suspected environmental pollutants and report the results instantaneously.
Airborne Fungal Analyses
With proper field sampling and laboratory testing techniques, confirmation of the presence of fungi can be made, and a plan for remediation formulated. Air samples are typically collected using an Anderson N6 air impactor, which will allow the amount and species of fungi present to be determined.
Surface Wipes & Vacuum Fungal Analyses
The sources of the fungi present in the air may be concealed from view. To investigate wall and stud cavities, the Wall-Chek sampling device, equipped with Zefron or Air-O-Cell capture media, may be used. Upholstered surfaces may also harbor fungi. Using a vacuum device equipped with specially developed dust collection bags, furniture, carpets and even hard surfaces can be sampled.
Dust Mite Analysis
In addition to fungi, upholstered surfaces and especially carpeting provide an ideal environment for the development of dust mites. R.I. Analytical Laboratories can provide advice, field-sampling services and data interpretation capability regarding dust mite issues.
