Field tests of automatic water-level monitor systems: Technology Development Program: Site Investigation Technology Project
Groundwater in the aquifer beneath the Hanford Site contains radioactive and other contaminants from deposits in the overlying vadose zone. These contaminants flow with the groundwater into the Columbia River. The rate of contaminant movement toward the river depends on hydraulic gradients resulting from aquifer recharge by process water and other liquid waste. Historically, hydraulic gradients were deduced from water-level measurements made manually using steel tapes. However, frequent or simultaneous measurements essential to proper site characterization and remediation under the Resource Conservation and Recovery Act; Comprehensive Environmental Response, Compensation, and Liability Act; and US Environmental Protection Agency (EPA) have been either too costly or impossible. This investigation was authorized to identify technologies capable of meeting site characterization and remediation requirements with precision suitable to EPA. Therefore, we identified and tested available automatic monitoring systems for cost-effective and timely measurements of aquifer water levels. 5 refs., 9 figs.
