&ER&   FACT SHEET:   LEAD  IN
              DRINKING  WATER  COOLERS
     Protecting the nation's children from exposure to lead from school drinking water coolers is the primary
     goal of the Lead Contamination Control Act (LCCA), which was signed into law on October 31,1988.
     EPA recommends that drinking water outlets-especially water coolers~in schools be tested to ensure
     that lead levels in the water are below 20 parts per billion.

     This fact sheet will help school administrators address the problem of school water coolers that contain
     lead. It reflects current information as of February 1990. The information on the accompanying list will
     be updated periodically.
         How To Identify Problems

         First, Identify which water coolers contain lead com-
         ponents; follow these steps as a minimum protocol.

         • Inventory each cooler and note Its brand, model,
         serial number, and year.

         • Check the accompanying list to identify any coolers
         that are not lead free.

         • Sample water from all outlets where lead contami-
         nation is most likely, especially coolers that are not
         lead free and those wtth lead-lined tanks. However,
         even coolers that are "lead free" may have high lead
         levels in their water due to other sources In the
         plumbing system and should be tested. Follow the
         sampling and testing protocols in the EPA booklet
         Lead in Schools Drinking Water. (See the box below,
         right)

         • Contact your State agency responsible for the
         LCCA program (see box below, right) for information
         and assistance on testing your water samples. Water
         samples should be sent only to certified laboratories
         that use the EPA-approved Graphite Furnace Atomic
         Absorption (AA) method. In some cases, the local
         water supplier, local or State department of health or
         environment, or the lab will collect and analyze the
         samples. In most cases, the lab will provide contain-
         ers and instructions for collection. The charge for lab
         tests ranges from $7 to $30 per sample. In some
         States or localities, there may be funding available for
         testing.
               What To Do If Problems Are Found


               If the lead level of any fountain or outlet exceeds 20 parts per
               billion (ppb), take immediate action to reduce the level of
               contamination. Rushing outlets on a daily basis before
               school begins may sufficiently reduce exposures, especially if
               the problem is localized to a few outlets in a building. How-
               ever, daily flushing may not be practical for water coolers.

               Take follow-up samples from any outlet with lead levels
               above 20 ppb to pinpoint the source of the problem. Make
               sure to follow the instructions in the EPA booklet Lead In
               School Drinking Water. If you find a cooler to be the source
               of the lead,  contact the distributor or manufacturer to deter-
               mine how the problem may be corrected. If a cooler that is
               not lead free is responsible for high lead levels, removal may
               be necessary.  The Consumer Product Safety Commission
               (CPSC) has the responsibility to issue an order to require
               manufacturers and importers to repair, replace or recall water
               coolers identified by EPA has having lead-lined tanks. Con-
               tact the CPSC Hotline (800/638-2772) to determine the status
               of their actions.

Fact Sheet: Lead In Drinking Water Coders
Water Coolers With Lead-Lined Tanks

The following list of model numbers represents all of the drinking water coolers with lead-lined tanks
that have been identified to date. The models listed here were selected because one or more of the
units in that model series have been tested and found to have lead-lined tanks. These six models
are made by the Halsey Taylor Company.

Other Water Coolers Containing Lead
EBCO Manufacturing Company
EBCO has identified all pressure bubbler water
coolers with shipping dates from 1962 through
1977 as having a bubbler valve containing lead,
as defined by the LCCA. The units contain a
single 50-50 tin-lead solder joint on the bubbler
valve. Model numbers for those coolers in this
category were not available.

The following EBCO models of pressure bubbler
coolers produced from 1978 through 1981
contain one 50-50 tin-lead solder joint each:

Pressure bubbler water coolers manufactured by EBCO and
marketed under the "Oasis" and "Kelvinator" brand names with
the identified model number* have been distributed in the U.S.
In addition, EBCO indicated that "Aquarius" pressure bubbler
water coolers are manufactured for distribution in foreign
countries, including Canada. Although unlikely, it is conceivable
that an "Aquarius" cooler with one of the model numbers listed
above could have been transported into the U.S.


































Halsey Taylor Company

In addition to these Halsey Taylor models,
Halsey Taylor indicates that the following
Haws brand coolers manufactured for Haws
