Under the Safe Drinking Water Act, EPA may publish Health Advisories (HAs) for contaminants that are not subject to any national primary drinking water regulation. 42 U.S.C. 300 g– 1(b)(1)(F). EPA develops HAs to provide information on the chemical and physical properties, occurrence and exposure, health effects, quantification of toxicological effects, other regulatory standards, analytical methods, and treatment technology for drinking water contaminants. HAs describe concentrations of drinking water contaminants at which adverse health effects are not anticipated to occur over specific exposure durations (e.g., oneday, ten-days, several years, and a lifetime). HAs also contain a margin of safety to address database uncertainties. HAs serve as informal technical guidance to assist federal, state and local officials, as well as managers of public or community water systems in protecting public health when emergency spills or contamination situations occur. They are not regulations and should not be construed as legally enforceable federal standards. HAs may change as new information becomes available. IV.

SUPPLEMENTARY INFORMATION:

I. General Information

A. How can I get copies of this document and other related information?

    1. Electronic Access. You may access this Federal Register document 
electronically from the Government Printing Office under the ``Federal 
Register'' listings at FDSys (https://www.gpo.gov/fdsys/browse/collection.action?collectionCode=FR). The Health Effects Support 
Documents and the Health Advisories for the cyanobacterial toxins are 
available on EPA's Web site at https://water.epa.gov/drink/standards/hascience.cfm. The Recommendations for Public Water Systems to Manage 
Cyanotoxins in Drinking Water document is available on EPA's Web site 
at https://www2.epa.gov/nutrient-policy-data/guidelines-and-recommendations.

II. What are cyanobacterial toxins and how are they produced?

    Algae and cyanobacteria are natural components of fresh water; 
however, under favorable conditions, they can rapidly multiply causing 
``blooms.'' Some cyanobacterial species can produce toxins 
(cyanotoxins) at levels that may be of concern for human health. These 
cyanobacterial toxins are of particular concern because of their 
potential impacts on drinking water and the potential to affect human 
health.

III. What are EPA's Health Advisories?

    Under the Safe Drinking Water Act, EPA may publish Health 
Advisories (HAs) for contaminants that are not subject to any national 
primary drinking water regulation. 42 U.S.C. 300 g-1(b)(1)(F). EPA 
develops HAs to provide information on the chemical and physical 
properties, occurrence and exposure, health effects, quantification of 
toxicological effects, other regulatory standards, analytical methods, 
and treatment technology for drinking water contaminants. HAs describe 
concentrations of drinking water contaminants at which adverse health 
effects are not anticipated to occur over specific exposure durations 
(e.g., one-day, ten-days, several years, and a lifetime). HAs also 
contain a margin of safety to address database uncertainties. HAs serve 
as informal technical guidance to assist federal, state and local 
officials, as well as managers of public or community water systems in 
protecting public health when emergency spills or contamination 
situations occur. They are not regulations and should not be construed 
as legally enforceable federal standards. HAs may change as new 
information becomes available.

IV. Information on EPA's Ten-Day Health Advisories for the 
Cyanobacterial Toxins, Cylindrospermopsin and Microcystins

    Today, EPA is making available the HA values for the cyanobacterial 
toxins microcystins and cylindrospermopsin. EPA recommends 0.3 
micrograms per liter for microcystins and 0.7 micrograms per liter for 
cylindrospermopsin as levels not to be exceeded in drinking water for 
bottle-fed infants and young children of pre-school age. For school-age 
children through adults, the health advisory values for drinking water 
are 1.6 micrograms per liter for microcystins and 3 micrograms per 
liter for cylindrospermopsin. The HA values are based on exposure for 
ten days.

V. Information on EPA's Support Document To Assist States and Utilities 
in Managing Cyanobacterial Toxins

    EPA also announces the release of a cyanotoxin management document 
that is a companion to the HAs for microcystins and cylindrospermopsin. 
The document is intended to assist PWSs that choose to develop system-
specific plans for evaluating their source waters for vulnerability to 
contamination by microcystins and cylindrospermopsin. It provides 
information and a framework that PWSs and others (as appropriate) can 
consider to inform their decisions on managing the risks from 
cyanotoxins to drinking water.
