How do you know if you’re doing a good job? You set goals, observe your progress against milestones and adjust when it makes sense.. That’s what groundwater monitoring is about too.
Groundwater monitoring programs are used for various reasons. One reason is to create a baseline for the site that alerts us to new issues that may arise. Another reason we use groundwater monitoring is to evaluate the effectiveness of remediation. In addition, most state regulations require groundwater monitoring, and the data collected shows if contamination levels have increased, decreased, or remained constant. This data will then determine if more work is required or if we can begin moving the site towards closure. In any case, groundwater monitoring is an effective and inexpensive way to determine the future of a site.
The science of groundwater modeling (and predictive modeling in general) has advanced greatly in the last ten years. Formally used only to model groundwater flow scenarios,the fate and transport mechanism of contaminated groundwater can now be mathematically predicted. Environmental regulatory divisions of many States now accept properly constructed, calibrated and field-checked models as a way to realistically address remediation and minimize cost.
Sierra Piedmont has a long history of providing one- and two-dimensional fate and transport modeling, including presentations to state regulatory agencies. Our models are constructed using field derived or conservative literature values, calibrated to field conditions and accuracy checked at periodic intervals during monitoring.
