What is the current Status of Aerially Deposited Lead
Prior to ban of adding lead to gasoline in 1974, tailpipe
emissions of lead from automobiles resulted in Aerially Deposited
lead (ADL) being deposited in and along roadways throughout the
State. ADL can still be found on roadsides and medians and
underneath some existing road surfaces due to past construction
activities. The deposited ADL highest concentrations are usually
found within the 10 feet of edge of the pavement, from the top six
inches of the soil to as deep as two to three feet below the
surface, and may on occasions extend 20 feet or more from the edge
of pavement. Here is a handy Flow
Chart to help you make informed decisions.
California Department of Transportation (CALTRANS) negotiated a Soil Management Agreement for Aerially Deposited Lead-Contaminated Soils (Agreement) with the California Department of Toxic Substance Control (DTSC), and updated it in 2016. To fulfill the terms of Agreement, CALTRANS evaluates the presence of ADL and through contract documents, will provide instruction to manage the ADL in their scope of work. You can read more about the details of the Agreement *and here is a summary:
Pre-Start Permits and Approvals
Before the projects starts, obtaining approval or permits from other state, regional, and local regulatory authorities may be required. Depending on project location, the following agencies may have notifications, permits or other requirements:
* State Water Resources Control Board (SWRCB),
* California Regional Water Quality Control Boards (RWQCBs),
* Water quality control plans and waste discharge requirements (including storm water permits),
* Coastal Zone Permits issued by the Coastal Commission, or its designees,
* California Department of Fish and Wildlife (DFW) permits, and \
* Air Quality Management District (AQMD) and/or Air Pollution Control District (APCD).
In ADL projects certain provisions must be met when lead is at or above specific levels see Chart below.
However, in all ADL projects the following precautions and requirements must be met:
Properly dispose of unused excess lead-containing soil.
If soil is to be placed at a site, then it must be placed in areas that are at least five feet above the maximum water table elevation so lead has a lesser chance of contaminating the groundwater.
Dust control is mandatory, specially more so during excavating lead-contaminated soil. You must take precautions to keep soils moist at all times, avoid creating visible dust, and to keep the soil stockpiles covered with thick plastic until it is reused. Depending on concentration of lead, some excavated soil may be reused within the designated freeway corridor from which it came.
When disturbing ADL soil, records must be kept and reported in details to DTSC. Copies of those records must be available to the public at applicable Caltrans District offices and at the appropriate information repositories.
Characterization of Potential Lead in Soil
CALTRANS uses historical data or will conduct soil sampling and laboratory analysis to determine the presence of lead in soil within project footprint. Statistical analysis model of 95% percent upper confidence level (UCL) are applied to analytical results of soil samples to decide how to manage the ADL-impacted soil.
Note: In order to evaluate analytical results by 95% UCL, minimum collection of at least a set of 4, but 8 or more suggested, soil samples are required. If this type of data analysis has not been performed, evaluations will be based on the maximum lead value detected.
ADL Soil Distinction
After testing the soil, depending on the lead content of the soil based on a 95 percent UCL, one of the following terms maybe used in the project specifications which indicate how to manage the soil within the project.
(Unrestricted if = TTLC < 80 mg/kg and STLC < 5 mg/l and TCLP < 5 mg/l)
If laboratory results of soil lead concentrations (TTLC) are below 80 parts per million (ppm or mg/kg) or soluble lead less than 5 mg/l based on the California Waste Extraction Test (CA-WET), then it is appropriate for use without restrictions at any property. Contractors must still take worker safety precautions though and use wet methods when handling it.
(Unrestricted if = TTLC > 80 mg/kg or STLC > 5 mg/l or TCLP > 5 mg/l)
When ADL average concentrations are over 80 mg/kg (or ppm) total lead or with concentration of equal to or greater than 5 mg/l soluble lead tested using the CA-WET, or concentration of equal to or greater than 5 mg/l soluble lead using the toxicity characteristic leaching procedure (TCLP), then it is considered regulated.
Whin the Regulated Soil, depending on concentration of lead soil can be handled as:
Type Com Material:
(Type Com if = TTLC > 80 but < 320 mg/kg and STLC < 5 mg/l)
Soil containing lead with levels below 320 ppm but above 80 ppm and extractable lead less than 5 mg/l, as determined by the CA-WET, may be removed from the State highway right of way without disposal in a landfill and are considered appropriate for use at commercial properties located outside the State right-of-way. CALTRANS shall submit to DTSC a completed “Agreement between a contractor working on State facilities and a real property owner for disposing construction-related material on property owner’s property” as part of the Completion Report. The soil may be temporarily stockpiled outside the project-defined construction corridor at a commercial facility of a contractor working on the project for CALTRANS. All such stockpiles shall be removed from commercial facility prior to completion of the highway project unless that location is to be the final resting place of the ADL-contaminated soil, in which case the soils will be managed according to all requirements.
Type Z-2 Material:
Type Z-2 material has average ADL concentrations greater than or equal to 1,000 mg/kg total lead or 5.0 mg/l soluble lead as determined by the CA-WET, and must be disposed at California class I disposal facility.
Before disposal of soil it needs to be characterized by laboratory methods specified in U.S. EPA SW-846 to determine appropriate landfill.
Transportation of ADL-contaminated soil will be done according to California Code of Regulations, title 22, division 4.5, chapter 13. That means that any transportation on public streets or highways must be performed by a licensed HAZWASTE Hauler.
Stockpiling of ADL-contaminated soil Within State Right-Away
Excavated ADL-contaminated soil designated for burial not placed into the designated burial area by the end of the working day shall be stockpiled on sheets of polyethylene or geomembrane and covered with either sheets of polyethylene or at least one foot of clean soil. The excavated ADL-contaminated soil shall be protected from contacting surface water and from being dislodged or transported by wind or storm water in such a manner that no ADL-contaminated soil is transported beyond the limits of the stockpile while the ADL-contaminated soils are stockpiled. The covers shall be inspected at least once a week and within 24 hours after rainstorms. If the ADL contaminated soil is stockpiled for more than 4 days from the time of excavation, Caltrans shall restrict public access to the stockpile by using barriers that meet the safety requirements of the construction zone.
The table below shows the actions that CALTRANS may take depending on the lead concentration of the soil.
Minimum Cover Requirements for ADL-contaminated Soil Based on Extractable and Total Lead Concentrations
Extractable Lead Concentration (STLC)
Total Lead Concentration (TTLC)
Minimum Cover Requirement

Greater than 150 mg/l DI-WET,or,Greater than 3200 mg/kg
Subject to full regulation as hazardous waste
Not Permitted to be used
What Does Caltrans want?
The special conditions require a plan to control exposure to
people or spills into the environment. The plan must address
disposal methods and testing the hazardous waste that is created
by the project. According to CALTRANS
Requirements, the Lead (or other hazardous material) Compliance
Plan must be approved by a Certified
Industrial Hygienist (CIH). Read the Special
Conditions carefully, some require continuous monitoring during
lead associated work. This can easily add daily cost to your
job of more than one thousand dollars a day. Please call me
after you have emailed the job information to me. I will
be glad to give you a good estimate of the job requirements.
Currently several regions are requiring unnecessary and costly air
testing for even small jobs that require less than several hours
to complete. The air testing is often a significant cost for
the value of the job! The really sad thing is that the short
duration air monitoring cannot obtain a level of detection LOD that is below the
action level. In short air monitoring less
than four hours does not produce reliable data and the results are
Do I need to notify Cal OSHA
when I do a lead job?
Yes, you need to notify for each job where the lead material is greater than 5000 PPM. Here is the form. Send it them in to your nearest Cal OSHA Office and keep a copy. The actual code is located at http://www.dir.ca.gov/Title8/1532_1.html. The specific exception is Exception No. 1: The employer is not required to notify the Division if: A. The amount of lead-containing materials to be disturbed is less than 100 square or 100 linear feet; or B. The only subsection (d)(2) task to be performed consists of torch cutting or welding, not to exceed a duration of 1 hour in any shift. No. 2: The employer is not required to notify the Division if the percentage of lead in the material disturbed is less than 0.5%, 5,000 parts per million (weight by weight), or 1.0 mg/cm. That means if you are moving aerially deposited lead (ADL) Soils or removing white or yellow traffic stripe no notice is generally required. Pay special attention to the ADL maximums listed in the 'specials' for each job. Just for your information 5000 ppm lead in soils would be a very high amount, and is not likely to be seen, we have not used lead containing gasoline for a very long time.
How do I Hire a CIH to do My ADL or Lead Based Paint Plan
Easy just select the kind of project and fill out the form and send it
to Dan Napier,CIH.
He will write a plan that meets your needs and that meets Caltrans
Is there a Minority Contractor that can do my lead control
plans (LCP) that are CIH certified?
Yes there is, call Nate Williams at (562) 804-4549 and he will do the work for you. He is the Go To Guy for a highly qualified SH&E minority company Safety Environmental Consulting has a CIH on staff.
Has anybody conducted Industry wide studies?
Yes we have, and the results are very good. The excavation of ADL has not been found to create an eight hour lead exposure above the permissible exposure level (PEL). If anyone has been able to document that high a lead level from ADL work projects I would like to add those results to my META Study. The studies are located at META Studies at DNA Industrial Hygiene.
Is the Marking and Line Removal (MLR)® or Bobcat ®Equipment
that removes traffic stripe and markings covered as a trigger
Some people have posited that the equipment is a power tool and is covered in the statute 1532.1. That is incorrect. The statute is enforced as: “Plain Language” when something is not defined elsewhere the DIR refers to the Merriam Webster Dictionary. The part of the standard quoted is under section (d) Exposure assessment
Here is the exact language:
(A) With respect to the lead related tasks listed in subsection (d)(2)(A), where lead is present, until the employer performs an employee exposure assessment as required in subsection (d) and documents that the employee performing any of the listed tasks is not exposed above the PEL, the employer shall treat the employee as if the employee were exposed above the PEL, and not in excess of ten (10) times the PEL, and shall implement employee protective measures prescribed in subsection (d)(2)(E).
The tasks covered by this requirement are:
1. Where lead containing coatings or paint are present: manual demolition of structures (e.g., dry wall), manual scraping, manual sanding, heat gun applications, and power tool cleaning with dust collection systems;
2. Spray painting with lead paint
The definition of tool in Merriam Webster:
Definition of tool
a : a handheld device that aids in accomplishing a task
b (1) : the cutting or shaping part in a machine or machine tool
(2) : a machine for shaping metal : machine tool
a : something (as an instrument or apparatus) used in performing an operation or necessary in the practice of a vocation or profession <a scholar's books are his tools>
b : an element of a computer program (as a graphics application) that activates and controls a particular function <a drawing tool>
c : a means to an end <a book's cover can be a marketing tool>
d often vulgar : penis
: one that is used or manipulated by another
plural : natural ability <has all the tools to be a great pitcher>
Clearly the equipment used to scarify the traffic Stripe does not fall under the definition of a tool. All other tasks identified by the section of the standard refer to “Hand” held devices. Finally the standard clearly states cleaning power tools with a HEPA Vacuum. The operation of the MLR or Bobcat systems is not a tool cleaning operation. They are designed devices that have been designed and proven to collect all lead dust when operated within the manufacturer’s guidelines. Any failure of the system is marked with a significant visible dust cloud.
There is no possible way that a MLR® or Bobcat® could possibly be identified as a hand held tool. There is no possible way that the use of either piece of equipment could be classified as a cleaning the tool with a HEPA vacuum.
Please refer to the META Studies that were published at the 2014 AIHCE in San Antonio, Texas.
How long does it take to do a typical Lead Compliance Plan?
The first time it usually takes several days, after that if you are doing the same type of work the plans can be completed very quickly. Some Districts are now accepting a CIH Sealed Acrobat PDF®. We of course provide those forms when you ask for them. Some Districts still need to get a wet signature CIH stamped paper original.
Is this the same as a Storm
Water Runoff Plan?
No it is not a Storm Water Pollution Prevention Plan (SWPPP), for that go to Cal_Storm Compliance Or Email Ken Kristoffersen. CAL-Storm Compliance has the certifications to meet the new requirements. After July 1st 2010, all SWPPPs must be prepared and signed off by a pre-qualified QSD, Qualified SWPPP Developer. The pre-requisites require a CA-PE or CPESC, Certified Professional, Erosion & Sediment Control, and by Sept. 2nd 2011,you must also have successfully completed and passed the State QSD class and test. To be a QSP, Qualified SWPPP Practitioner, must have completed and passed either the CISEC or CESSWI programs, and by Sept. 2nd successfully completed the state QSP class and test. Make certain that the people offering to do your SWPPP's are qualified to do the work. For even more SWPPP information check the State FAQ. If you want the two plans bundled, please just call Dan Napier, CIH at 800-644-1924 x 103.
What is the CALTRANS Z-2 Y-2 designations about?
This Information is of historical interest only it all changed June 30, 2016. The only thing left is Z2
Material that contains ADL in average concentrations (using the 90 percent Upper Confidence Limit) of 1.5 mg/L or less extractable lead (based on a modified waste extraction test using deionized water as the extractant) and 1,411 mg/kg or less total lead. This material is a California hazardous waste that may be reused as permitted under the variance of the DTSC provided that the lead contaminated soil is placed a minimum of 5 feet above the maximum historic water table elevation and covered with at least 1 foot of non-hazardous soil.
Material that contains ADL in average concentrations (using the 90 percent Upper Confidence Limit) that exceed either 1.5 mg/L extractable lead (based on a modified waste extraction test usingdeionized water as the extractant) or 1,411 mg/kg total lead but are less than 150 mg/L extractable lead (based on a modified waste extraction test using deionized water as the extractant) and less than 3,397 mg/kg of total lead. This material is a California hazardous waste that may be reused as permitted under the variance of DTSC provided that the lead contaminated soil is placed a minimum of 5 feet above the maximum historic water table elevation and protected from infiltration by a pavement structure which will be maintained by the Department.
Material that contains ADL in average concentrations (using the 95 percent Upper Confidence Limit) greater than or equal to 1,000 mg/kg total lead, greater than or equal to 5.0 mg/L soluble lead (as tested using the California Waste Extraction Test), and the material is surplus; or material that contains ADL in average concentrations greater than 150 mg/L extractable lead (based on a modified waste extraction test using deionized water as the extractant) or greater than 3,397 mg/kg total lead. This material is a Department-generated California hazardous waste and must be transported to and disposed of at a California Class I disposal site.
Material that contains ADL in average concentrations (using the 95 percent Upper Confidence Limit) greater than 5.0 mg/L soluble lead, (as tested using the Toxicity Characteristic Leaching Procedure). This material is a Department-generated federal hazardous waste and must be transported to and disposed of at a California Class I disposal site.
Can I get a CIH any time I want?
Well, no. There only about 10000 CIH's
the entire world. There are several hundred in California, many
work for companies, or agencies. There are many that can help you,
us for example. Find a CIH you like and
stick with them, in the long run they will be able to protect you
and your company from excess costs, citations and problems with
your Safety & Health program (IIPP).
Do I have to fill out any special forms?
Yes, generally you need to notify for each job where the lead material is greater than 5000 PPM. Here is the form. Send it them in to your nearest Cal OSHA Office and keep a copy. The actual code is located at http://www.dir.ca.gov/Title8/1532_1.html. The specific exception is Exception No. 1: The employer is not required to notify the Division if:A. The amount of lead-containing materials to be disturbed is less than 100 square or 100 linear feet; or B. The only subsection (d)(2) task to be performed consists of torch cutting or welding, not to exceed a duration of 1 hour in any shift. No. 2: The employer is not required to notify the Division if the percentage of lead in the material disturbed is less than 0.5%, 5,000 parts per million (weight by weight), or 1.0 mg/cm. That means if you are moving aerially deposited lead (ADL) Soils or removing white or yellow traffic stripe no notice is generally required. You can fill it out online and print it, but you cannot save it unless you have Adobe Acrobat.®
Does CALTRANS deal with Lead any differently than anybody else?
Well they do have special arrangements with the California
Department of Public Health, (CDPH.)
beds, under certain conditions. They can do some leachate testing
using DI water instead of acid. All of this is very esoteric and
should be discussed with your CIH
who can discuss the finer points with the CALTRANS Resident Engineer RE.
What is Lead Air monitoring?
Air monitoring is a measure of the lead or metal in the air for
the entire work shift (it should be eight hours), it is reported
in µg/m3 or micrograms per cubic meter of air. TheCal OSHA number
is 30µg/m3 (Action Level) with 50 µg/m3
for the PEL (Permissible Exposure Level.) Anything above 30
triggers personal protection, blood testing and a whole host of
requirements. There is nodirect connection between the ADL in soil
and air monitoring. Soil is measured in parts per million,
sometimes expressed as mg/kg, it is the same thing! Air
monitoring however is expressed in micrograms per cubic meter of
air. OSHA references 5000 ppm for lead based paint, and 600 ppm
for surface coatings. Generally speaking material below 600
ppm lead does not require that air monitoring or PPE be provided
unless the task is one of the "Trigger Tasks". However the
air monitoring results taken when good dust control methods are in
place maintain the Lead in Air well below the 30 µg/m3
What is the difference between LEAD by GFAAS 7105 and LEAD by Flame AAS 7082?
The short answer is that 7105 has a lower level of detection than
7082. The limit of detection (LOD) for 7082 is around 2
micrograms, the LOD for 7105 is around 0.05 micrograms.
NIOSH has not verified the LOD for GFAAS (7105) The cost of the
two methods is very different. 7105 requires much more work
in the laboratory and is therefore co$t$ more than 7082. The
San Francisco Bay Area air quality management district requires
that lead levels are demonstrated to be very low, so Bay Area lead
monitoring literally requires that you use 7105 without specifying
it. Sometimes the specials ask you to meet the lower levels
provided by 7105,
but they then specify that you use 7082 as the "method". You
simply can not get there with 7082,
the LOD is 2.6 micrograms per sample.
Where and Who is a good Laboratory?Contact your CIH to learn what needs to done, and read the additional air monitoring information here.
I tested the air and found No Lead, why do I have to keep testing?
Good news, you may not need to keep on testing. A properly
qualified CIH can help you to test and submit documentation that
you do not need to do air monitoring tests if you found lead at
levels above the action level for at least the next twelve
months. If you found NO Lead at all you may not need to do
air monitoring again unless you change your operation or means oof
working. For ADL or stripe removal there is no requirement
to continuously test. You may not need to do anymore air
monitoring, but read the CODE very carefully. Please refer
to the META Studies that
were published at the 2014 AIHCE
in San Antonio, Texas.
What are all the Lead tests about anyway?
The person who is accepting the waste is the one who will tell
you what tests to conduct. It may vary, even in the same state. So
ask the landfill before you waste your good money on the wrong
test. Your CIH will be able to help you with these complex

This test takes several days to complete.
TTLC Total Threshold Limit Concentration (Wet Weight
milligrams/kilogram mg/kg (or PPM the same thing) This test can be
completed in about 2 hours, 1.5 Hours extraction in Strong acid,
this is a fast test.

TCLP (40 CFR 136) is the Federal Method, 18 hours of extraction
with acetic acid at different Ph solutions depending on the Ph of
the original material. The STLC (California Title 22 § 66700) is a
48 hour extraction. Generally the California method results in a
slightly higher level of lead, but both are very similar. If
anything the STLC can be used instead of the TCLP for anything in
California, If the disposal is in another State, use the TCPL or
The tests extract the metal from the sample, or try to dissolve
the material and cannot be done twice with the same material, the
minimum amount of material is at least 50 grams for each test, so
if you want to do both tests the sample size needs to be 200 grams
about ˝ a pound of material. You can get Urine Test Collection
bottles from a medical supply house. They are the right
size, inexpensive and clean (Sterile).
What all this means is that you have to have your load waiting to
be disposed of for a minimum of three days for California Waste,
and at least two days for Federal waste. Do not think you can have
a truck load ready, conduct the test, read some readout and send
the driver off. You will have to load the bin, do the test wait
for the material to be at the lab more than 18 or 48 hours, and
then get a fax from the lab after all the Quality Control checks
have been made. Extraction is only one part of the analysis and
the law specifies how long. You cannot order the lab to give you
immediate turnaround for STLC that immediate turnaround would
still be 48 hours, minimum. The folks in the lab need time to run
the sample, type it have lunch etc.
The magic number for California is STLC lead 5 mg/liter for lead compounds or organic
Seventeen Metals STLC 5 TTLC 1000
The magic number for Federal TCLP for lead is 5 mg/liter
TCLP Eight Metals As 5 Ba 100 Cd 1 Cr 5 Pb 5 Hg 0.2 Se 1.0 Ag 5
Do the TTLC first, if it is below 1000, and above 10 times the
STLC but below you must do STLC if above the STLC it is hazardous,
if below it is non hazardous.
If TTLC is less than 10 X the STLC it is automatically non
hazardous. eg Lead 45 is less than 10X5 or 50, therefore
How Long Do Waste Characterization Tests Last?
Regulatory rules to classify a waste as California hazardous for handling and disposal are contained in the CCR, Title 22, Division 4.5, Chapter 11, Article 3, §66261.24.
How to determine if waste is Resource, Conservation, and Recovery Act (RCRA) hazardous is in Chapter 40 of the Code of Federal Regulations (40 CFR), Section 261.
For waste containing metals, the waste is classified as California hazardous when:
1) the representative total metal content equals or exceeds the respective Total Threshold Limit Concentration (TTLC); or
2) the representative soluble metal content equals or exceeds the respective Soluble Threshold Limit
Concentration (STLC) based on the standard Waste Extraction Test (WET).
A waste has the potential of exceeding the STLC when the waste’s total metal content is greater than or equal to ten times the STLC value since the WET uses a 1:10 dilution ratio. So, when a total metal is detected at a concentration greater than or equal to ten times the respective STLC, and assuming that 100 percent of the total metals are soluble, soluble metal analysis is required. A material is classified as RCRA hazardous, or Federal hazardous, when the representative soluble metal content equals or exceeds the Federal regulatory level based on the Toxicity Characteristic Leaching Procedure (TCLP).
In general you have to use the first testing results for waste characterization. However you cannot use laboratory results that are old. The age factor is determined by the place where you want to take the waste material. For example, if you want to take the material to say “ Clean Harbors in California”say at the Buttonwillow Landfill Facility, and you think it contains lead from a test that was conducted in situ (testing done on soils in a fixed location, not yet excavated) and was conducted two years ago,. I understand that the waste facility cannot use that laboratory data because it is more than one year old. In that case reclassification by WET is required, prior to transport to and acceptance at the facility.
How fast can I get results?
That depends on the test, air monitoring can be returned the next
day, but the cost is pretty steep. Tests for hazardous materials
require a "Leachate" test and that requires that the laboratory
soak the test material for 48 hours as part of the analysis. Again
you need to get information from your CIH and the Laboratory to be
able to plan these projects. CALTRANS has a special agreement with
CDPH and they can do the leachate test with DI water rather than
acid. CALTRANS has a system of identifying soil types,
check out the Flow
Chart to see what you can do with what you have.
Who Can Help me Dispose of the Waste?
Pete Timmerman at 925-457-3781 or email him at firstname.lastname@example.org.
Pete will handle the waste characterization, (Profiling) and get
the waste samples to the appropriate lab. Coordinate the pick-up
with the waste hauler. Generally, coordinate with CalTRANS and
answer their questions and comments.
What kind on containers can I
In short you can use a DOT Approved Container. Usually the specials have more specific requirements. Because of recent problems, the specials require the materiel to be stored in a secure area. You cannot transport the waste anywhere but on the job. Do not drive around with this in your truck unless you just happen to be a licensed hazwaste hauler on their way to a transfer and storage site (TSD) or waste site. The only thing that you can do is package the waste on site. Pursuant to CCR T22, Article 3, section 66262.30 - Before transporting hazardous waste or offering hazardous waste for transportation off site, a generator shall package the waste in accordance with the applicable Department of Transportation regulations on packaging under Title 49 CFR Parts 173, 178, and 179.
Where can I get Hazardous Waste Bins?
49 CFR, Part 173: Shippers-general requirements for shipments and packaginghttp://www.fmcsa.dot.gov/rules-regulations/administration/fmcsr/fmcsrruletext.aspx?reg=r49CFR173.24
Call Sean Kelly (909)963-8265 at ECTI. All you need is a DOT
approved container, so you can use barrels, or super sacks. You
are not limited to roll off bins.
Who will cite me about these lead or other exposures?
Well that depends on what you are doing. If it is about your employees, Cal-OSHA or the Division of Industrial Relations, Department of Occupational Safety will enforce rules in regards to your employees. The local Air Quality Board AQMD in Los Angeles for instance will cite you for environmental crimes. Dumping something where you should not, or making a visible dust cloud.
How far can they go back for something I did long ago and far
The usual length of time is three years, OSHA is limited to one year. The tricky part is that the AQMD (EPA) Agency time starts when they found out about the problem. You can read more at HTTP://www.dnacih.com/StatuteofLimitations.pdf
Does lead really cause Childhood Intelligence disorders?
After all he effort to remove lead we do not have a single
incidence of improvement in intelligence in the studied
