Public Invited to Meeting on Bianchi/Weiss Greenhouses

New York State Department of Environmental Conservation (DEC), in conjunction with the State Department of Health (DOH) will hold a public meeting on Monday, Nov. 14, at 7 p.m., to present a proposed clean-up plan for the Bianchi/Weiss Greenhouses site in East Patchogue.

The meeting will be held at the South Country Library located at 22 Station Road in Bellport. At the meeting, DEC and DOH staff will describe the cleanup proposal (called a Proposed Remedial Action Plan) that was developed under New York's State Superfund Program. The document can be reviewed at the Patchogue-Medford Library and the DEC Region One office, or on DEC's website at http://www.dec.ny.gov/chemical/8431.html.

The remedy proposed for the site includes excavation and off-site disposal of contaminated soil, connection to public water for private well owners impacted by site contamination, basement sump upgrades of off-site properties located within shallow site-related groundwater contamination, and groundwater monitoring. This remedy also includes the implementation of institutional and engineering controls. DEC and DOH believe this remedy is protective of human health and the environment and best satisfies the remediation objectives detailed in the draft cleanup plan.

This proposed remedy represents the alternative preferred by DEC and DOH to address site contamination. The draft cleanup plan has several goals, including to:

  • identify cleanup levels to be achieved;
  • summarize other alternatives considered;
  • explain how the proposed remedy will protect public health and the environment; and
  • provide a detailed description of the proposed remedy.

The proposed remedy was chosen following a detailed investigation of the site and evaluation of alternatives to address contamination, called a "Remedial Investigation/Feasibility Study."

Details of the remediation includes:

  1. Excavation and off-site disposal of 46,000 tons of chlordane and lead contaminated soil. On-site soils will obtain residential soil cleanup objectives and off-site soils will obtain unrestricted use cleanup objectives.
  2. Properties with potable wells located within or near the chlordane groundwater plume and impacted by chlordane will be offered connection to public water.
  3. Properties located within the shallow portion of the chlordane contaminated groundwater will be evaluated and where appropriate, property owners will be provided with an offer to have foundation cracks sealed and filters placed on the sump pump discharges to remove chlordane to acceptable discharge levels.
  4. Abandon irrigation wells located on-site.
  5. Imposition of an environmental easement for the site that requires development of a site management plan. The site management plan will detail site restrictions, maintenance of engineering controls, groundwater monitoring activities, and periodic certification requirements.

DEC will consider public comments as it finalizes the remedy for the site. The selected remedy will be described in a document called a "Record of Decision" that will explain why the remedy was selected and respond to public comments. This document will be made available to the public. The project then moves to designing and performing the cleanup action to address the site contamination.

DEC will keep the public informed during the cleanup of the site.


The site is listed as a Class "2" site in the State Registry of Inactive Hazardous Waste Sites (list of State Superfund sites). A Class 2 site represents a significant threat to public health or the environment; action is required.

The site covers 14 acres and is presently undeveloped. The site is zoned for residential use and residential properties surround it. The site was previously used for commercial growing purposes from 1929 to 2005. Between January and June 2009, DEC repaired the fence to limit site access, placed silt fencing, hay bales and mulch to prevent surface runoff and dust migration, and removed contaminated soils within stockpiles and impacted dry wells to limit off-site exposures and impacts to the environment. Pesticides are the primary contaminants of concern detected during the remedial investigation, which was completed in August 2011.

Project documents are available at the Patchogue-Medford library at 54-60 East Main Street in Patchogue and the DEC Region One office at 50 Circle Road in Stony Brook. These documents are available to help the public to stay informed and include the proposed cleanup plan for the site, called the "Proposed Remedial Action Plan."

Written comments about the proposed remedy will be accepted by DEC for 30 days, from Nov. 1 - Nov. 31, 2011. Submit written comments and project related questions to:
