The US EPA received a referral from the NJDEP on November 14, 2014 to assess the former Kil-Tone Company Site located at 527 East Chestnut Avenue, Vineland NJ and the surrounding properties for a CERCLA removal action. The Kil-Tone Company manufactured arsenical pesticides from the late 1910s until the late 1930s.

LERCO, a former fuel distribution facility, is situated across Chestnut Avenue from the former Kil-Tone Co. property, and has been a fuel distribution facility since the 1930s. Remedial work to address petroleum related constituents in soil and groundwater has been performed on the LERCO property under the NJDEP LSRP program. Elevated levels of arsenic and lead are present in the soil and groundwater at the LERCO property, with arsenic levels as high as 20,000 ppm and lead levels as high as 28,700 ppm found in the soils at depth (4’ depth). LERCO has attributed the contamination to the former pesticide manufacturing operations at the Kil-Tone Company Site.

NJDEP initiated a sampling event in August 2014 at the former Kil-Tone Co. property and the surrounding residential properties to determine if the properties are impacted by historic operations at the Kil-Tone Co. Arsenic and lead were detected in the top 6” of soil at residential properties at concentrations as high as 83 ppm and 1,100 ppm, respectively. Elevated levels of arsenic are present on the former Kil-Tone property at concentrations in the top 6” of soil as high as 740 ppm and at depth as high as 5,800 ppm (3.5-4’ depth).

Arsenic has been detected in the groundwater at both the LERCO property and the Former Kil-Tone Co. Site. Groundwater samples collected from temporary well points on the Kil-Tone property have arsenic present that ranges from 8.1 ppb to 14,000 ppb. Arsenic concentrations as high as 15,100 ppb is present in groundwater collected from monitoring wells at the LERCO property .

In January and February 2015, the US EPA conducted soil sampling at 27 residential properties located closest to the Former Kil-Tone Site property. Several soil borings were installed across each property, and samples were collected from the following 4 depth intervals within each boring: 0-2”, 2-6”, 6-12” and 12-24”. Elevated concentrations of lead and arsenic exceeding the EPA Residential RMLs (67 ppm for arsenic; 400 ppm for lead) are present in the surface soils (0-2’) at 19 of the 27 residential properties sampled.

Residential soil sampling was expanded to include additional properties to determine the extent of contamination. from June 8 to July 1, 2015. Soil sampling was completed at a total of 35 homes out of the 48 homes targeted for Phase II residential sampling. Approximately 827 soil samples have been collected and sent to the DESA lab for TAL analysis.

A storm sewer catchbasin is located on the 527 East Chestnut Avenue property that drains into the Tarkiln Branch. The head of the Tarkiln Branch is located across South East Boulevard and receives storm water runoff from the downtown area of Vineland as well as the Former Kil-Tone Company Site property. In April 2015, EPA conducted sediment, flood plain and surface water sampling along the Tarkiln Branch and portions of the Parvin Branch to determine if there has been any impacts from the Site to the tributary. The Tarkiln and Parvin Branches are tributaries to the Maurice River.

Elevated concentrations of arsenic and lead are present in the sediments and flood plain areas along the entire stretch of the Tarkiln Branch to the confluence of the Maurice River. The data is currently being reviewed to determine what residential properties lie within the impacted areas and will need to be evaluated for removal eligibility. The data is also being shared with the RPM for the Vineland Chemical Site due to the potential impacts to the Maurice River and Union Lake.

On June 22nd, ERT began a high-resolution characterization of the Site soils using a CPT/XRF to determine the horizontal and vertical extent of contamination on the Site property. A Geoprobe collected soil cores to obtain visual comparisons for the CPT logs and confirmation samples were collected from the soil cores for lab analyses on the XRF data. Arsenic concentrations have been detected at 47,000 ppm and lead concentrations have been detected at 119,280 ppm in the soils near the former rail spur on the CPT/XRF. Field XRF of the soil borings collected near the location of the former grinding house have recorded concentrations of both arsenic and lead at 100%.

Soil sampling was conducted from October 10 – 20, 2015 on residential properties located within the flood plain of the Tarkiln Branch. Concentrations of arsenic exceeding the Removal Management Level (RML) of 67 mg/kg were detected within the top 6” of soil on eight of the properties sampled.
