(A)
The following
action levels for microcystins are based, in part, on the United States
environmental protection agency's "Drinking Water Health Advisory for the
Cyanobacterial Microcystin Toxins," dated June, 2015 and apply to all public
water systems, including consecutive water systems:
(1)
0.3 micrograms
per liter (ug/L) for people under the age of six, pregnant women, nursing
mothers, those receiving dialysis treatment and those with pre-existing liver
conditions.
(2)
1.6 ug/L for all individuals.
(B)
Exceedance of these action levels in samples collected at a finished water
sampling point or a distribution sampling point will require additional
monitoring, and potentially other actions as described in this chapter of the
Administrative Code.
