What Are the Risks at the Site?
Arsenic and lead-contaminated soil and sediment have been released and transported from the surface soils on the former Kil-Tone site property and into the storm sewer that discharges to the Tarkiln Branch, a tributary to the Maurice River. The current land use in the vicinity of the site is primarily residential and commercial, and the area is densely developed. Exposure to arsenic and lead contaminated soil on properties near the former Kil-Tone facility presents unacceptable human health risks to residents from incidental soil ingestion and dermal contact.
EPA has classified inorganic arsenic as a known human carcinogen through both oral (skin cancer) and inhalation (lung cancer) routes of exposure. Inhalation of elevated concentrations of arsenic can also result in respiratory effects, including sore throat and irritated lungs. Oral exposure to arsenic can cause skin changes, including patches of darkened skin and the appearance of small "corns" or "warts" on the palms, soles, and torso, and are often associated with changes in the blood vessels of the skin. Skin cancer may also develop. Chronic oral exposure to arsenic at low concentrations can lead to skin effects and to circulatory and peripheral nervous disorders. There are some data suggesting that inhalation of inorganic arsenic may also interfere with normal fetal development.
Lead is a cumulative poison where increasing amounts can build up in the body eventually reaching a point where symptoms and disability occur. Particularly sensitive populations are women of childbearing age, due to the fetal transfer of lead, and children. Cognitive deficits are associated with fetal and childhood exposure to lead. An increase in blood pressure is the most sensitive adverse health effect from lead exposure in adults. Effects on the kidney, nervous system and heme-forming elements are associated with increasing blood lead concentrations, both in children and adults. Other symptoms include: decreased physical fitness, fatigue, sleep disturbance, aching bones, abdominal pains, and decreased appetite. EPA has determined that lead is a probable human carcinogen.
EPA uses performance measures to track environmental results at Superfund sites. If you have any questions or concerns about the measures at this site, please contact the site team members listed under Site Contacts.

|Status at this
|What does this mean?|
|Human Exposure Under Control||Insufficient Data||Yes means assessments indicate that across the entire site:
No means an unsafe level of contamination has been detected at the site and a reasonable expectation exists that people could be exposed.Insufficient data means that, due to uncertainty regarding exposures, one cannot draw conclusions as to whether human exposures are controlled, typically because:
|Groundwater Migration Under Control||Insufficient Data||
Yes means EPA reviewed all information on known and reasonably expected groundwater contamination. EPA concluded the migration of contaminated groundwater is stabilized and there is no unacceptable discharge to surface water. EPA will conduct monitoring to confirm that affected groundwater remains in the original area of contamination.
No means EPA has reviewed all information on known and reasonably expected groundwater contamination, and the migration of contaminated groundwater is not stabilized.
Insufficient data means that due to uncertainty regarding contaminated groundwater migration, EPA cannot draw conclusions as to whether the migration of contaminated groundwater is stabilized.
Yes means the physical construction of the cleanup is complete for the entire site.
No means either physical construction is not complete or actions are still needed to address contamination.
|Sitewide Ready for Anticipated Use||No||Yes means:
No means that one or more of these three criteria have not been met. However, a site listed as no may still have redevelopment occurring on portions of the site and may be eligible for additional redevelopment.
