Welcome to the former Ciba Geigy facility community update website

This site serves as a source of news and information regarding progress at the former Ciba Geigy facility located in Cranston, Rhode Island for the residents and surrounding communities.

Objectives

Under the guidance of the U.S. Environmental Protection Agency (USEPA) and Rhode Island Department of Environmental Management (RIDEM), BASF, as the current property owner, is implementing measures to ensure the site remedy and restoration efforts achieve these three key objectives:

1. To make sure that the former Ciba Geigy facility in Cranston is protective of human health and the environment;

2. To ensure the remediation activities facilitate reuse and repurpose of portions of the property; and

3. To preserve and enhance the ecological assets of the property in a manner that creates value to the local community and region.

Update - July 2026

A Sediment Sampling Report was prepared to document the sediment sampling and sediment cap inspection that was completed in 2025 and 2026. The report was submitted to the USEPA on July 31, 2026. A copy of the report can be found here.

Site History

In 2009, BASF Corporation acquired the property upon which the former Ciba Geigy facility was located and took over the remediation that had begun under Ciba. Since that time, BASF has brought a fresh perspective to address the site and has been working diligently in cooperation with EPA to complete remediation.
