As part of the Corrective Measures Study, FMC will include a study on the feasibility of soil tilling as a technology to reduce surface contamination of arsenic by blending uncontaminated soil below the surface with contaminated top soil.

A couple of methods will be used: tilling and bull dozing. The tilling study will be performed on two parcels in Middleport, one in the Air Deposition Area and one along Culvert 105. A combination of shallow tilling and bull dozing will be used on the parcel along the culvert. A deep tilling machine will be used on the parcel in the Air Deposition Area. This machine can till soil up to 3 feet deep. Use this link to view a picture of this machine.

FMC will perform this experiment the week of November 16th, weather permitting.

As part of the Corrective Measures Study to be performed in Middleport by FMC under guidance by the government agencies (USEPA, NYSDEC and NYSDOH) there was a risk assessment study conducted by Dr. Rosalind Schoof of Integral Consulting. The assessment will be used to determine how the arsenic contamination in Middleport soils affects the residents and at what levels contamination becomes a concern.

The result of the survey can be viewed by clicking here.

Dr. Schoof is an internationally recognized expert on arsenic in the environment and has performed past studies on the arsenic contamination in Middleport.

Dr. Schoof held information workshops on November 4th and 5th. A flyer was delivered door to door in the CMS study areas. That flyer can be viewed by clicking here.

Question: Is there a study which indicates what levels of arsenic in soil are acceptable/safe to permit human habitation?


Yes indeed there are several! Anaconda Montana, Denver Colorado and Omaha Nebraska are just a few. The one fact to be aware of is that each state has their own criteria for acceptable levels of arsenic in soil. In Anaconda it is 250 PPM, in Denver it is 75 PPM in Omaha it is 70 PPM for children, adults much higher. In New York it is 13 and 16 PPM depending on the land usage. The reason for the disparity is what naturally occurs in each state and what assumptions are used by the calculating government agencies. What seems to be lost is that we are all the same species of humans and what is safe for one region should be the same for another.

For more information and documents covering some of the studies, look through the Document Repository on this site in Arsenic In Soil - Related Documents within the repository section. (Use this link). The Health Consultation report for Omaha prepared by the Agency for Toxic Substances and Disease Registry which is part of the Federal Department of Health and Human Services is one of the documents there (look for Health Consultation - East Omaha, Nebraska).

The final versions of RFI Volumes 1, 2 and 4, agreed to by the government agencies with oversite responsibilities of the Middleport RCRA project, is available in the Document Repository of this site. Click here to go to the category containing the volumes.

Volume 1 contains background and historical information, Volume 2 has the Facilities Investigation of the Air Deposition Area of the village which is that area south of the Erie Canal to Route 31 (Rochester Rd.) and Main St. east to the Niagara/Orleans County line. Volume 4 has the Facilities Investigation of Culvert 105 which is a drainage pathway starting at the railroad tracks north of the FMC plant running to the sewage treatment plant on N. Hartland St.

The draft version for Volume 5 is also there however this volume is currently undergoing revisions negotiated between FMC and the Agencies. This volume has the Facilities Investigation of the Jeddo Creek Tributary (Tributary #1) from Francis St., north to Pearson Rd.

These volumes report on the investigation of the extent of arsenic contamination in soils and creek beds in their respective areas.
