Current vapor intrusion (VI) pathway assessment heavily weights concentrations from infrequent (monthly–seasonal) 24 h indoor air samples. This study collected a long-term and high-frequency data set that can be used to assess indoor air sampling strategies for answering key pathway assessment quest...
