The site name is used to identify a particular facility or area
of interest to the Minnesota Pollution Control Agency (MPCA).
This name is used by MPCA staff to group wells into a particular
ground water monitoring project. A single well can be used in
more than one ground water monitoring project.

The concentration of a groundwater contaminant, or a mixture of
contaminants, that can be safely consumed daily for a lifetime.
It is expressed as a concentration in micrograms per liter (ug/L).

The concentration of a groundwater contaminant, or a mixture of
contaminants, that poses little or no risk to health, even if
consumed daily over a lifetime. The Minnesota Department of
Health develops HBVs in response to requests from other Minnesota
agencies that have found a contaminant in groundwater.

A data system developed by the Minnesota
Geological Survey and the Minnesota Department of Health for
storing, retrieving and editing well water information. The CWI
database contains basic information such as location, depth and
water level for wells drilled in Minnesota. It also contains
construction and geological information from the well record
(well log) for many wells.

The maximum level at which a contaminant can exist in drinking
water without having an adverse effect on human health.

(a) Any substance defined in the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA) of 1980 (but
not including any substance regulated as a hazardous waste) or
(b) petroleum, including crude oil or any fraction thereof that
is liquid at standard conditions of temperature and pressure.
Petroleum and petroleum-based substances are comprised of a
complex blend of hydrocarbons derived from crude oil through
processes of separation, conversion, and finishing, such as

POMS are a broad class of compounds that includes the
polycyclic aromatic hydrocarbon compounds (PAHs), of which benzo
[a]pyrene is a member. POM compounds are formed primarily from
combustion and are present in the atmosphere in particulate
form. Sources of air emissions are diverse and include
cigarette smoke, vehicle exhaust, home heating, laying tar, and
grilling meat. Cancer is the major concern from exposure to
POM. Epidemiologic studies have reported an increase in lung

"Dioxins" refers to a group of chemical compounds that share
certain chemical structures and biological characteristics.
Several hundred of these compounds exist and are members of
three closely related families: the chlorinated dibenzo-p-
dioxins (CDDs), chlorinated dibenzofurans (CDFs) and certain
polychlorinated biphenyls (PCBs). Sometimes the term dioxin is
also used to refer to the most studied and one of the most
toxic dioxins, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). CDDs
