* Status Codes: P • proposed, F - final

-------
Legend for draft version of Drinking Water Standards and Health Advisories table.
Abbreviations column descriptions are:
NIPDWR - National Interim Primary Drinking Water Regulation. Interim enforceable
drinking water regulations first established under the Safe Drinking Water
Act that are protective of public hearth to the extent feasible.
MCLG - Maximum Contaminant Level Goal. A non-enforceable concentration of a
drinking water contaminant that is protective of adverse human health
effects and allows an adequate margin of safety.
MCL - Maximum Contaminant Level. Maximum permissible level of a contaminant
in water which is delivered to any user of a public water system.
Rf D - Reference Dose. An estimate of a daily exposure to the human population
that is likely to be without appreciable risk of deleterious effects over a
lifetime.
DWEL - Drinking Water Equivalent Level. A lifetime exposure concentration
protective of adverse, non-cancer health effects, that assumes all of the
exposure to a contaminant is from a drinking water source.
O The codes for the Status Reg and Status HA columns are as follows:
F - final
D - draft
L - fisted for regulation
P - proposed (Phase II draft proposal, based on levels proposed in 1985)
Other codes found in the table include the following:
NA - not applicable
PS - performance standard 0.5NTU-1.0-NTU
TT - treatment technique
- No more than 5% of the samples may be positive. For systems collecting fewer
than 40 samples/month, no more than 1% may be positive.
*** - guidance
t - Large discrepancies between Lifetime and Longer term HA values may occur
because of the Agency's conservative policies, especially with regard to
carcinogenicity, relative source contribution, and less than lifetime exposures in
chronic toxicity testing. These factors can result in a cumulative UF (uncertainty
factor) of 10 to 1000 when calculating a Lifetime HA.
