T/ACEF 260-2026 Technical specification for investigation and assessment of organic matter pollution in river, lake and reservoir sediments

Scope

This document specifies the technical requirements for the investigation and evaluation of organic matter pollution in the sediments of rivers, lakes, and reservoirs, including terms and definitions, evaluation principles and processes, on-site investigation and sample handling, evaluation factors, evaluation methods, evaluation grading, and results. This document is applicable to routine investigations and special evaluations of organic matter pollution in the sediments of rivers, lakes, and reservoirs. Organic matter pollution investigations and evaluations for projects such as endogenous pollution control, ecological dredging, and aquatic ecosystem restoration can refer to this document for implementation. 4.
