Priorities and Technologies
for Indicative testing

Ballast Management in the Great Lakes

This Guidebook is a product of a project headed by Principal Investigator, Jeffrey L. Ram on “Automated Ballast Treatment Verification” (Project 964 of the Great Lakes Protection Fund). Ballast water of commercial ships is the leading vector for aquatic invasive species (AIS) into and within the Great Lakes of North America. 

This report focuses on the priorities and technologies for indicative ballast water monitoring in the Great Lakes. Indicative monitoring enables assessment of successful ballast water management systems (BWMS) operations and compliance with state, national, and international ballast discharge regulations. It is also critical for accurate assessment of harmful organism hazards and prevention program success in the Great Lakes. The goal of this project is to protect the Great Lakes by helping assure that indicative monitoring systems designed to assess invasive species management are effective in this unique freshwater ecosystem.

What is our purpose?

Ballast water management represents a complex challenge that in order to be effectively addressed it must be done in collaboration with the input of regulators, ship owners, scientists, environmental organizations and other stakeholders.

Our goal is to be a source of relevant ballast water information that encourages ideas, generates conversation and creates solutions to prevent potential threats that pose serious ecological, economic and health problems.

What is
Ballast Water?

Ballast water is essential for safe shipping operations. A ship’s ballast water system allows it to pump water in and out of large tanks to counterweight for a change in cargo load providing stability and maneuverability when not carrying enough weight to face rough seas.

Knowledge of ballast water indicative monitoring technologies underlying particular monitoring capabilities is important for assessing their theoretical and practical fit with Great Lakes applications.


Allegra Cangelosi and Dr. Jeffrey L. Ram convened indicative ballast water monitoring technology developers, Great Lakes government officials and other stakeholders in two 2-day Practicum workshops held in Superior, WI and Erie, PA in 2019.
