Outsmarting the Dirt ~ Remediation Part 1 by Thomas D. Dalzell, CWD Director of Environmental Research AMS, Inc. For those readers who were able to read all parts of both Outsmarting the Dirt ~ Soil Sampling and Outsmarting the Dirt ~ Groundwater Sampling , in previous issues of WWDR , some of the basic components are repeated in this Remediation series for consistency and applicability. Please consider any repe- tition as a reminder of the importance of all phases of subsurface investigation and remediation. For new readers, the overall goal of subsurface environmental drilling investi- gations (EIs) is important to consider in every phase. The very basic steps of re- medial investigations, remediation, and site closure are emphasized in this series. EIs are conducted using a variety of sample collection techniques with tool- ing associated with direct push drilling technology (direct push) and/or conven- tional drilling. Samples are collected because EIs are primarily used for two main purpos- es: 1) as a preliminary subsurface site investigation; and 2) the basis to conduct a detailed and strategic remedial investigation and the subsequent development of a remedial action plan (RAP). It is not adequate just to know there is contamination in the subsurface. The contamination type and concentration must be specifically identified; and the exact ver t ical and lateral extent of the soi l and/or ground- water which has been affected, type of soil, and characteristics of the groundwater must all be determined. Specifically, one of the main goals of developing a suc- cessful RAP is to protect and restore g r o u n d w a t e r resources. A second ma i n g o a l o f t h e RAP is to restore or rehabilitate the prop- erty (site) for future use, where human health is protected w h i l e u s i n g a n d occupying the site that was negatively impac t ed by t he existence of subsur- face contaminants. Ul t imately, the entire project, from soil and groundwater sampling to develop- ment of a RAP, is to develop a strategy to protect human health and the envi- ronment, and then appropriately imple- ment it. Be sure to look for Part 2 next month. Tom Thomas D.

Si se detectan “mezclas que causen preocupación” en el agua potable más arriba de los límites de concentración establecidos por laAgencia de Protección Ambiental, u otro estado o agencias lo- cales, pueden requerirse tratamientos del agua antes de que sea distribuida por los sistemas de suministro de agua pública. El costo del tratamiento depen- de del tipo de mezclas detectada y su concentración. El tratamiento del agua, es usualmente una tarea costosa. El dicho “una onza de prevención vale tanto como una libra de cura” definiti- vamente se aplica al proteger nuestros suministros de agua.
