Coastal Contaminant Migration Monitoring Technology Review
Abstract
Growing evidence suggests that submarine groundwater discharge may represent an important migration pathway for natural and anthropogenic constituents entering coastal waters. To address this issue, a series of technologies were investigated for their applicability toward direct quantification of coastal contaminant migration via groundwater. Technologies were divided into two categories: (1) technologies for quantifying groundwater flow to coastal waters, and (2) technologies for detecting contaminants in the groundwater-coastal water exchange zone. The technologies evaluated for quantifying groundwater flow to coastal waters include seepage meters, thermal gradient flow meters, piezometers, thermal infrared aerial imagery, tracer injection, a colloidal borescope, and natural geochemical tracers. The technologies for detecting contaminants in the groundwater-coastal exchange zone include porewater probes, mini-wells, diffusion samplers, seepage meters, and in situ chambers. A matrix was developed to evaluate these technologies. The factors for consideration of each technology include technical performance/applicability, developmental status, reliability, and cost. A panel of experts will fill out the matrix and the selected technologies will then be evaluated for a demonstration based on the panel results.
