Developing an Exposure Dose
Drinking Contaminated Groundwater
We estimated an exposure dose of each contaminant a person might receive by drinking
the contaminated groundwater (Risk Assistant, 1994). We used the maximum contaminant
level found in groundwater. Children represent a sensitive subpopulation and doses that
are protective of children are most likely protective of adults. For non-cancerous
compounds, we estimated the exposure dose that an elementary school child, weighing 24
kilograms (50 pounds), would receive drinking about a half liter of contaminated
groundwater a day, 250 days a year for 6 years. For carcinogenic compounds, we
estimated an exposure dose that an adult, weighing 70 kilograms (150 pounds), would
receive over a lifetime (70 years) of drinking 2 liters contaminated groundwater a day.
Household Use of Contaminated Groundwater
Contaminants in domestic water may evaporate from various water sources in the home
and contaminate indoor air. People may be exposed to contaminants by breathing
contaminated air. To estimate indoor air concentrations, we used the maximum
contaminant level found in groundwater. For non-carcinogenic compounds, we estimated
an exposure dose an elementary school child would receive from breathing contaminated
indoor air, 9 hours a day, 250 days a year. We estimate children breath at a rate of 0.76
cubic meters an hour. For carcinogenic compounds, we estimated an exposure dose an
adult would receive from breathing contaminated indoor air, 21 hours a day, 350 days a year for 70 years (Risk Assistant, 1994).
Exposure to Contaminated Soil
Exposure to surface soil is currently a completed exposure pathway and exposure to
subsurface soil is a potential exposure pathway. We assume children consume a
significant amount of soil, relative to adults, as a result of outdoor play. When children have
access to areas of contaminated soil, they may incidentally eat the soil resulting in a
significant source of exposure to contaminants. Even though adults are less likely to eat
significant amounts of soil, soil ingestion remains a potentially significant source of
exposure to environmental contaminants through hand-mouth activities, smoking and
eating. We estimated an exposure dose of each contaminant a child (for potential non-cancer effects) and adult (for potential carcinogenic effects) might receive by coming into
contact with contaminated soil.
For non-cancerous compounds in soil, we estimated the exposure dose that an elementary school child, weighing 24 kilograms (50 pounds), would receive by incidentally eating 200 milligrams of contaminated soil 350 days a year for 6 years. Children represent a sensitive subpopulation and doses that are protective of children are most likely protective of adults. For carcinogenic compounds, we estimated an exposure dose that an adult, weighing 70 kilograms (150 pounds), would receive over a lifetime (70 years) of incidentally ingesting 100 milligrams of soil a day, 350 days out of the year (Risk Assistant, 1994).
The amount of dust from contaminated soils residents might breathe was also estimated. For a child we used an inhalation value of 0.76 cubic meters an hour which corresponds to one-third of a day at rest and the rest of the day doing light activity. For adults, we used 1.67 cubic meter per hour which corresponds to on-third of the day at rest and the remaining day divided between light, moderate and heavy activity (Risk Assistant, 1994).
