Sentence examples for remediation operations from inspiring English sources

High-resolution site-characterization methods are needed to support accurate risk assessments and to select, design, and operate effective remediation operations.

Therefore, contaminants in the bypassed areas may not be contacted by the amendments in the remedial fluid, which may significantly prolong remediation operations.

Sound knowledge of the spatial distribution of the discharged pollutants in sediments is therefore crucial for designing monitoring strategies and suitable remediation operations.

In managing source zones, decision tools are needed for the assessment of suitability of specific technology to a site and design remediation operations to achieve desired end-points.

These findings have implications for predicting the progress and cost of remediation operations involving enhanced calcite precipitation where mineral precipitation rates, and the spatial/temporal distribution of those rates, can have significant impacts on the mobility of contaminants.

In particular, we illustrate how the HPDP approach enables flexible and efficient simulation of a complex contaminant capture system at one of the largest groundwater pump-and-treat remediation operations in Michigan.

Column experiments designed to simulate typical remediation operation of daily wetting and draining cycles of contaminated water amended with an electron donor.

In fact, contaminant transfer from low to high mobility regions at the back end of a contaminant plume (i.e. back diffusion) is responsible for the long-term release of contaminants during remediation operation.

Nine wells were identified that required remediation after operations were performed leading to a remediation probability estimate of 1.8% and a 95% confidence interval ranging between 0.6 and 3.0%.

A modeling approach is described for optimizing the design and operation of groundwater remediation at DNAPL sites that considers uncertainty in site and remediation system characteristics, performance and cost model limitations, and measurement uncertainties that affect predictions of remediation performance and cost.

The purpose of this paper is to estimate the probability that a dry tree well abandoned using rigless methods, the most common approach in the shallow water Gulf of Mexico, requires remediation after initial operations are completed.
