P&S utilizes efficient, reliable and cost-effective field investigation strategies. MicroWell® Technology, a highly successful alternative to conventional drilling, was developed by P&S and P&S pioneered the use of soil gas analysis. P&S's field sampling of ground water, soil, or soil gas, combined with mobile lab services, provides real-time results. P&S's equipment is compact and lightweight, allowing for sampling in sensitive areas such as wetlands, woodlands, and inside buildings.
