Method synopsis

Long-term analysis of drinking water treatment facility DBP concentrations to identify seasonal and decadal trends in organic matter export from source watersheds. Uses quarterly regulatory compliance data to understand watershed biogeochemical processes.

Synthesized from method descriptions across 2 papers using this protocol.

Procedure as described in the canonical source

Steps below were extracted from the paper that introduces this protocol — Disinfection byproducts formed during drinking water treatment reveal an export control point for dissolved organic matter in a subalpine headwater stream (2022), Water research X. Implementations in other papers (listed below) may differ.

1. Historical data collection and analysis
   Historical DBP data were analyzed from 2005 to 2020 from the Crested Butte drinking water treatment facility. The DBP data included quarterly reports for total trihalomethanes (TTHM) and the five regulated haloacetic acids (HAA5). Linear trend lines were fitted to the raw data using ordinary least square regression in Tableau version 2020.4.
   Quantities: 15 years of quarterly data from 2005-2020, analyzing TTHM and HAA5 concentrationsDuration: 15-year historical dataset analyzedConditions: Quarterly sampling throughout all seasons
   Equipment: Tableau version 2020.4

Typical Equipment

• Tableau version 2020.4

Output Measurements

• TTHM concentrations
• HAA5 concentrations
• temporal trends
