     (5)  Investigations should be conducted to develop more
information where these pollution indicator levels are exceeded.

lakes and reservoirs shall be 0.025.
     (7) Where the criteria are exceeded and there is a reasonable
basis for concluding that the indicator bacteria E. coli are
primarily from natural sources (wildlife), e.g., in National
Wildlife Refuges and State Waterfowl Management Areas, the criteria
may be considered attained provided the density attributable to
non-wildlife sources is less than the criteria. Exceedences of
E. coli from nonhuman nonpoint sources will generally be addressed
through appropriate Federal, State, and local nonpoint source programs.
     Measurement of E. coli using the "Quanti-Tray 2000" procedure
is approved as a field analysis. Other EPA approved methods may
also be used.
     For water quality assessment purposes, up to 10% of
representative samples may exceed the 668 per 100 ml criterion
(for 1C and 2B waters) and 409 per 100 ml (for 2A waters). For
small datasets, where exceedences of these criteria are observed,
follow-up ambient monitoring should be conducted to better
characterize water quality.
