Landfill as an option for waste
disposal has emerged as a natural
choice due to its economic benefits.
Landfills were usually managed in
a way that the moisture entering in
could be minimized. The
development of better liner
materials, helped to prevent
pollution leaching into the
subsurface and manage gas
collection. Because of this
important factor we are able to
covert waste into renewable
energy.

in cells that may encompass 50 to 150 acres (or
more). They attract varmin, birds, bears and

8. Maintain site fencing and all access restrictions.
Install additional monitoring and/or extraction
wells as needed to control groundwater flow.
Provide on-site remedial workers with
adequate protective equipment and training,
and follow appropriate National Institute of
Occupational Safety and Health and
Occupational Safety and Health
Administration guidelines.
9. Conduct quarterly monitoring of nearby
private residential wells to determine if
groundwater migration is impacting these
wells.
Conduct chemical-specific air monitoring of the
on-site breathing zone for benzene and other
VOCs to evaluate potential harmful health
effects to on-site workers breathing this air.

11. Modern Landfills
As long as there are people on the
planet, there will be garbage. The
rubbish often piles up in landfills
that produce a harmful
greenhouse gas called
methane. VOA's Stephanie Ho
reports solid waste managers have
been working to turn this methane
into something good -- namely,
clean energy.
12. Health Activities
Recommendations
Panel (HARP)
Recommendations
“The data and information
developed in the Public Health
Assessment for Modern Landfill
site, York County, Pennsylvania,
has been evaluated by ATSDR's
Health Activities Recommendation
(HARP) for appropriate follow-up
health activities. Although
exposure to on-site workers may be
currently occurring and probably
has occurred in the past, this site is
not being considered or follow-up
health activities at this time
because the levels and duration of
exposure cannot be characterized.
This site will be re-evaluated when
the on-site breathing zone air
sampling results, as recommended,
are available.”
13. Based on the information reviewed, PADOH has
concluded that this site represents no apparent public
health hazard, since available data do not indicate that
off-site humans are being or have been exposed to
levels of contaminants that would be expected to cause
adverse health effects, and there are no community-
specific health outcome data to indicate that the site
has had an adverse impact on human health. However,
comprehensive data or information are not available
for all environmental media to which on-site workers
may be exposed. If the results of the following,
recommended, chemical-specific air monitoring of the
on-site breathing zone indicate the on-site air poses a
health threat, the site may be reassessed and a Public
Health Assessment Addendum prepared.
