ASTM WK40037, Guide for Determining Concentration Values from Groundwater, Air and Soil Gas Using Adsorbent-Based, Passive Samplers, will link easy to use, cost-effective, and nonintrusive passive sampling with concentration data to measure vapor intrusion. Demonstrating that compound concentration in air, soil gas, or water can be measured accurately and provide defensible quantitative data, this standard will help promote avoidance of health problems associated with vapor intrusion.
