Frequently Asked Questions about Monitored Attenuation in Groundwater

TRRP Training: 2022 Program

presented by: GSI Environmetal Inc.

Texas Risk Reduction Program regulations (TRRP; 30 TAC 350) establish consistent risk-based protocols for assessment and response to soil, groundwater, or surface water impacts associated with environmental releases of regulated wastes or substances.

Presented by GSI Environmental Inc., this popular and informative training series is a must for professionals who need a working understanding of TRRP and those needing to stay up-to-date with the latest TCEQ TRRP guidance and policies.

TRRP Training Course (2 Days): Provides an overview of the TRRP framework and step-by-step training on property assessment and response action procedures established under the TRRP rule

Attendees will become acquainted with rules, key guidance and policies covering affected property assessments, protective concentration levels, and response actions. The course material presents strategies for efficient project management in compliance with TRRP and explains the various report forms adopted by TCEQ.

Abstract

Download Paper

Monitored natural attenuation (MNA) can be used to manage long-term obligations at contaminated sites. The objective of this project was to prepare a technically sound and concise guidance document answering frequently asked questions (FAQs) about MNA that will aid in the understanding and implementation of MNA.The FAQ format is characterized by a series of one-sentence “questions” followed by technical “answers” that cover one or two pages apiece. The intensive use of graphics provides a more effective and visually appealing means for conveying information. The answers provide links to other question/answer pairings within the FAQ document that deal with related topics, as well as references to other scientific publications that can provide further information. Because it compiles and references an extensive amount of source materials, this type of document represents an ideal starting point for readers who want to seek out additional information and serves as a valuable tool for project managers trying to assess the feasibility of using MNA at their sites.This effort extends and complements existing work (e.g., Natural Attenuation of Chlorinated Solvents by Wiedemeier, Rifai, Newell, and Wilson, 1999); provides resources and key information about new MNA technology breakthroughs (e.g., compound-specific isotope analysis, molecular biological tools); presents new developments in how MNA is applied (e.g., source zone MNA); presents MNA solutions and approaches for a wide variety of constituents (e.g., inorganics, radionuclides); provides context for how emerging fate and transport processes (e.g., matrix diffusion) impact the application and attractiveness of MNA; and introduces new concepts about site management (e.g., “low-risk” site management).
