Public Notification/Water Use Advisories for Cyanotoxins in Drinking Water

Above Health Advisory Value for Bottle-Fed Infants and Young Children of Pre-School Age but Below Health Advisory Value for School-Age Children through Adults

We are providing this notice to make you aware of the presence of low levels of [insert specific cyanotoxin] in your treated drinking water. [insert specific cyanotoxin here] is a cyanotoxin, created by certain types of harmful algal blooms in the source water of your drinking water supply. The cyanobacteria in harmful algal blooms that produce [insert specific cyanotoxin here] can grow rapidly when certain environmental conditions are favorable for their growth. Since not all ‘blooms’ produce these cyanotoxins, we sampled the treated drinking water to determine if cyanotoxins were present when a suspected bloom was occurring. The sampling conducted on [insert date] and confirmed on [insert date] indicated that the cyanotoxins are present in treated drinking water. We are adjusting our treatment operations to reduce concentrations of [insert specific cyanotoxin here] as quickly as possible.

[Insert boundaries of service area affected]

The cyanotoxins were detected at levels that may present a risk to bottle-fed infants and young children of pre-school age if ingested. Some consumers who have a suppressed immune system may also be at risk. We recommend that bottle-fed infants and young children of pre-school age and consumers with suppressed immune systems use an alternative source of water for ingestion and the preparation of infant formula use an alternative source of water until further notice.

Boiling water will not remove the cyanotoxins. The water is considered safe for humans for bathing, showering, washing hands, watering yards and gardens, washing dishes, flushing toilets, cleaning, laundry, and shaving.

We are working diligently to correct this problem, and do not expect this problem to last more than [insert number of days]. We will provide further notice when the water is again safe to use for all purposes. Additional information can be found at insert link to additional information. If you have any questions or concerns please contact us at insert phone number.
