Volunteer Monitoring

NEIWPCC has established a Volunteer Monitoring Workgroup, comprised of appropriate state, federal and local representation.

The goal of this workgroup is to find solutions for the problems that can occur when working with volunteer data, and to improve states’ ability to accept and work with volunteer monitoring data.

This page will be used as a resource for state and federal staff, as well as for volunteer groups and other interested parties. This page will be updated frequently with recent workgroup activities. Below, you will find resources provided by NEIWPCC and the states for volunteer groups, listed by state.


Connecticut implements a three-tiered system for sorting and using volunteer data.

Tier 1– Data typically are in the form of digital photos or written descriptions of observations. These data can be helpful as a record of an episodic event. Tier 1 data are not likely to provide sufficient information to formalize an assessment, but can provide supporting information when other data exists for a waterbody.

Tier 2– Data collected may not have been collected under a formal Quality Assurance Project Plan (QAPP). Tier 2 data are not likely to be enough information to formalize an assessment, but can provide supporting information when other data exists for waterbody.

Tier 3– Data are collected under a formal monitoring plan which follows a QAPP approved by DEEP or US EPA. QAPPs shall include laboratory tests to be used and data quality objectives. Standard Operating Procedures for field procedures and lab techniques should be explained as well as a plan for data management. Chemistry results should be provided from a statecertified laboratory. Taxonomic identifications should be from a taxonomist with sufficient experience to provide reliable taxonomic identifications, preferably with certifications by the Society for Freshwater Science and American Fisheries Society. Project objectives should be consistent with DEEP’s use of data for waterbody assessment purposes. Tier 3 data may be used to support use assessments.

Massachusetts Department of Environmental Protection (MassDEP) welcomes help from outside groups to gather data on surface water quality.

You can find guidelines for submitting data to MassDEP here.

General guidance on completing a Quality Action Project Plan (QAPP), a necessary component to collecting usable data, can be found here.

New Hampshire Department of Environmental Services (NHDES) utilizes the help of dedicated state-wide volunteers who offer their time to aid NHDES in their efforts. This network of volunteers is part of the NHDES Volunteer Lake Assessment Program (VLAP).

Information on VLAP can be found here.

A training section with a video and a link to the VLAP QAPP can be found here.
