PETITIONED HEALTH CONSULTATION

DRY BRIDGE ROAD LANDFILL (HOMETOWN PROPERTIES)
NORTH KINGSTOWN, WASHINGTON COUNTY, RHODE ISLAND

 


CONCLUSIONS

1. The on-site and off-site ambient air and on-site soil pathways from the Dry Bridge Road Landfill present No Apparent Health Hazard now or in the future. This conclusion is based on a review of ambient air data and restricted site access.

2. Based on a review of municipal groundwater data, the municipal groundwater pathway in North Kingstown, Rhode Island, is No Apparent Health Hazard in the past, present, and future. The Rhode Island Department of Environmental Management requires quarterly groundwater monitoring of solid waste management facilities until the landfill is closed and biannnual monitoring for 30 years after closure to prevent potential future impact to municipal water systems. Under the authority of the Safe Drinking Water Act, EPA regulates all chemicals in this municipal water supply of North Kingstown.

3. The on-site and off-site ambient air and soil exposure pathways in the past are an Indeterminate Public Health Hazard based on the lack of past hydrogen sulfide sampling data and the lack of soil characterization.

 

RECOMMENDATIONS

1. Continue quarterly monitoring of the groundwater of the Dry Bridge Road Landfill to ensure that contaminants are not migrating from the site.

2. Maintain existing engineering controls at Dry Bridge Road Landfill.

 

PUBLIC HEALTH ACTION PLAN

The actions described in this section are designed to ensure that this public health consultation identifies public health hazards and provides a plan of action to mitigate and prevent adverse health effects resulting from exposure to hazardous substances in the environment.

Actions Completed:

1. Hometown Properties, Incorporated, has installed several engineering controls at the Dry Bridge Road Landfill to abate environmental impact and nuisance odors. These controls are as follows:

  • Application of Posi-Shell
  • Installation of a landfill gas collection system
  • Installation of two landfill gas flares
  • Implementation of a hydrogen sulfide removal system (SulfaTreatĀ®)

2. The Rhode Island Department of Environmental Management has required indoor air monitoring of residential and commercial buildings near Dry Bridge Road Landfill and quarterly monitoring of groundwater and landfill gas.

3. The Rhode Island Department of Environmental Management collected and analyzed soil samples from the residence that borders Dry Bridge Road Landfill.

Actions Planned:

1. The Rhode Island Department of Environmental Management, in cooperation with Hometown Properties, will sample groundwater and landfill gas monitoring wells at the Dry Bridge Road Landfill quarterly until closure and biannually for 30 years after closure. This groundwater and landfill gas sampling regime focuses on preventing any potential off-site migration of contaminants from the landfill.

2. The Rhode Island Department of Environmental Management, in cooperation with Hometown Properties, requires maintenance of existing engineering controls in the 30-year post-closure plan of Dry Bridge Road Landfill.

3. ATSDR will evaluate surface soil sampling data that the Rhode Island Department of Environmental Management collected from the residence bordering the Dry Bridge Road Landfill, and an additional health consultation will be published evaluating the health implications of incidental ingestion and dermal contact.
