Indoor Environment includes all aspects: noise, lighting, overcrowding, vibrations, ergonomic stressors, psychosocial stressors and indoor air quality (IAQ). Indoor air quality is the most common aspect. We test for mold, radon, fumes (VOC's), bacteria, pesticides, particulates, etc. We also offer asbestos abatement and inspection services. If another company is performing abatement, we can perform the air monitoring to ensure the project is completed properly. We serve all of South Dakota at this time and offer residential & commercial services.
