Questions that deserve
measurable answers.

The research approach behind CWMP: connect forestry-herbicide applications, water monitoring, and project-level evidence.

The question behind the work

What reached the water?
Did the protections work?

CWMP’s research agenda connects herbicide-use records with environmental measurements. We want to understand what happened after an application, how the evidence relates to a specific project, and what it can tell us about water-quality protections.

Our focus is the connection between the treatment site and the waters below it—not simply a map of applications or an isolated list of laboratory detections.

A historical research proposal

The research foundation

Start with the
actual application.

EMC-2022-001 proposed using application notices to guide sampling and comparing herbicide measurements with use information. [Original proposal, pp. 4–6]

CWMP seeks to build on that approach through independent, project-level source investigations and public evidence.

Our research agenda

Connect the questions
to the evidence.

SOURCE INVESTIGATION

Which project?

Bring together treatment records, geography, timing, chemical behavior, weather, and sampling patterns. Investigate alternative sources alongside the initial hypothesis.

MONITORING DESIGN

Which measurements?

Evaluate how sampling locations, timing, laboratory methods, and reporting limits affect what an investigation can establish.

REGULATORY EFFECTIVENESS

Which protections?

Examine the requirements applicable to a project, records of their implementation, and the environmental results. Keep questions about compliance distinct from questions about effectiveness.

A planned line of inquiry

Compare the requirements.
Examine the results.

We intend to compare regional forestry water-quality requirements and Board of Forestry and Fire Protection protections with the monitoring evidence available for specific projects. That work includes tracing relevant changes over time and identifying what information is needed to evaluate their outcomes.

Future research publications should distinguish requirements on paper, implementation records, chemical sampling, and source investigations. The comparison is an area of planned work, not a completed statewide finding.

How we will present the evidence
