Upon collection, each sample would be monitored by an Organic Vapor Analyzer (OVA) to provide additional data concerning the vertical distribution of organic species. ' All one inch diameter holes created during the day will be backfilled to the q� ground surface using a cement/bentonite mixture. Although this will require entering each property twice during the day, it is the most effective way to assure that all test holes are properly sealed.
