Groundwater Remediation Sensor Procurement Specifications: A Shanghai ChiMay Buyer’s Guide

Groundwater sensor procurement is not the same as buying process instruments. A wellhead sonde may sit in the same casing for a decade or more, in reduced conditions, with biofilm growing on it and no one watching. The procurement decision that matters is therefore not unit price — it is drift specification, warranty, spares availability…

Ammonia Nitrogen and Nitrate Trends in Pump-and-Treat Effluent: A Shanghai ChiMay Analytical Brief

Where Nitrogen Contamination Comes From Groundwater nitrogen impacts most commonly originate from: Fertilizer application on agricultural land. Concentrated animal feeding operations (CAFOs). Septic system leach fields, especially aging systems. Industrial ammonium discharges from fertilizer manufacturing and food processing. Landfill leachate, which routinely carries ammonia nitrogen in the tens to hundreds of mg/L, and higher in…

Leachate Treatment Sensor Procurement Under the PFAS Hazardous-Constituents Framework: A Shanghai ChiMay Buyer’s Guide

PFAS regulation has changed how landfill leachate instrumentation is specified, but not always in the way the headlines suggest. EPA’s February 2024 proposal to list nine PFAS as RCRA hazardous constituents remains pending as of mid-2026 — it was not finalised in April 2026, and the agency withdrew a separate RCRA corrective-action definition rule in…
