Today's Feature Post Tornado
Lead and Zinc.
News Release -
With Joplins history of lead and zinc
mining, many areas of Jasper County, including
the parts of Joplin and Duquesne affected by the
devastating EF-5 tornado that struck on May 22,
2011, have or may have mine waste contaminants,
such as lead and cadmium, present in the soil.
Mine waste contaminants
containing lead pose a primary concern because of
the health effects on young children when exposed
to this metal. Cadmium exposure in this situation
also can be a concern, espcially when long-term
exposure occurs.
In the 1990s, the
Environmental Protection Agency conducted soil
testing throughout Jasper County. As a result of
the soil tests by the EPA indicating high levels
of mine waste contaminants on properties in
certain sections of the County, Jasper County and
the City adopted ordinances designating mine
waste areas and a "smelter zone" in
those areas where the soil contained unacceptable
levels of lead and cadmium. The "smelter
zone" area was determined by soil test
results with unacceptable contaminant levels
until the EPA reached areas with soil test
results showing acceptable readings.
Currently, these ordinances
require soil lead testing in these known areas
designated by the EPA, which are generally
located in the northwest and western sections of
Joplin. The ordinances require yards in the
smelter zone and mine waste areas to be tested
when applying for a building permit. The maps for
"known" Mining Waste and Smelter Areas
and for Historic Mined Areas are available on the
Jasper County website at
www.health.jaspercounty.org.
While most of the
tornado-affected area is outside the mine waste
areas and "smelter zone", it is
possible that yards which were previously below
acceptable levels, based on lead exposure levels,
could now be above acceptable levels after the
tornado cleanup is complete, due to the
circumstances caused by the storm.
This may have occurred because
the properties in the tornado-damaged areas were
already developed prior to the EPAs
identification of mining areas and the presence
of any waste material was covered by soil for
yards to be established. The contamination may
also have occurred because mine waste material
was used for fill underneath driveways,
sidewalks, or crawl spaces when the homes in the
storm affected area were built. Since those
structures were destroyed in the tornado-affected
area, the different materials may now be exposed
in the soil that has been disrupted by the
tornado.
As property owners in the storm
affected area have started to rebuild and have
requested soil lead tests from Jasper County,
test results in the affected area are becoming
available. To date, 44 properties have been
tested in the tornado area, with 19 properties
testing above the acceptable yard average level
of 400 parts per million.
Due to the test results in the
tornado-affected area, the City is urging
residents to test their soil when they start to
rebuild. Yards should be tested as property
owners begin to rebuild, since excavation during
construction disturbs the soil.
"With Joplins past
mining activities and the chat used underneath
homes during construction, we are aware of the
possibility of finding high lead levels in the
soil that has been disturbed by the
tornado," said Health Director Dan Pekarek.
"At this time, we are strongly encouraging
our residents to obtain a free soil lead test as
they rebuild their homes in the storm affected
area.
Homeowners can contact the
Jasper County Health Department for free soil
testing. If contamination is found, the inspector
will work with the property owner to establish a
remediation plan. Remediation typically includes
either removing the contaminant and hauling it to
an approved site for disposal, or capping the
contaminant in place with an effective barrier
such as contaminant free soil, mulch, concrete
driveway, etc. For questions or to schedule
testing please call (417) 358-0475 or
877-879-9131 between 8:30 a.m. and 4:30 p.m.,
Monday through Friday.
The City has requested
assistance to remediate yards with unacceptable
lead and cadmium levels from our federal and
state partners to help our residents address this
issue as our community begins the rebuilding
process. We are also aggressively working on
grants to help remediate contaminated yards
according to an approved remediation plan
developed by the Jasper County Health Department.
As any remediation aid becomes available, the
City will pass this information on to property
owners.
As the soil test results from
the EDR (Expedited Debris Removal) area have
become available, the City Council will be
considering a change to the current ordinance at
the October 17th Council meeting to require soil
lead testing in the EDR area, in addition to the
current mine waste areas and the "smelter
zone" for the safety of our residents. More
information will be released as this issue is
further defined.
