What are Algae?• Single-celled plants• Possess chlorophyll• Conduct photosynthesis.

Normally, NOT HARMFUL
• Algae are present in all lakes and oceans
• Most kinds do not cause any harm
• Diverse communities of many types of algae

Acronym time: HABs
H: Harmful (toxins, economic aesthetics, ecological)
A: Algal (freshwater HABs refer to cyanobacteria, not truly algae)
B: Blooms (proliferation of cells, dense concentrations)

Cyanobacteria – Blue-green Algae – HABs• Highly specialized and
competitive Some regulate buoyancy Some fix nitrogen
• Best in high temps, high light, high nutrients
• Causes not fully understood, hard to predict

HABs need Nutrients and Light to Thrive• Lakes that have higher nutrients
are more likely to have HABs• HABs are present in low nutrient
waterbodies too (Finger Lakes, Lake Placid)
• Causes not fully understood• Some low P systems bloom,
some high P systems don’t bloom
• Interannual variability within lakes

Wild Cards Affecting HABs1. Climate change2. Trophic interactions
• increased nutrient recycling
• selective feeding by dreissenid mussels
3. Emerging contaminants

Common types of CyanobacteriaDolichospermum Aphanizomenon Microcystis
• Adjusts buoyancy• Produces microcystin (liver
toxin)
• Fixes Nitrogen• Produces anatoxin (nerve toxin) and
others

CyanotoxinsMicrocystins (liver toxins)
• Most common toxin in New YorkAnatoxins (nerve toxins)
• Potentially fatal to dogsLipopolysaccharides (endotoxins)
• Skin irritants and allergens• Produced by most cyanobacteria
Other Toxins (Cylindrospermopsin, Saxitoxin, BMAA, etc.)No visual cues that toxins are presentSample collection is warranted

Any health effects should be reported to your local health department!
Routes of exposure to toxins1. Consumption: incidental
swallowing, drinking water
2. Inhalation: aerosols created during household use or recreation
3. Dermal: skin contact during swimming

Exposure PotentialIngestion, inhalation and/or direct contact:
• Cyanobacteria cells― Associated compounds (LPS,
Phycocyanin, other?)
• Secondary metabolites i.e. cyanotoxins― Microcystins: hepatotoxin― Anatoxin-A: neurotoxin― Cylindrospermopsin: hepatotoxin
• Secondary infection
*Whether toxins are present or not, there is still a concern for health effects.

(watermeal and duckweed)
• Discolored water• Blooms of other types
of algae

Recognizing HABsPROBABLY HABs• Floating on surface of the
water• Streaks, clumps, pea soup
or spilled paint appearance• Often bright green (or
bluegreen, white-ish, or purple)

Surveillance/sampling• DEC coordinates several HABs and lake
monitoring programs (DEC lake monitoring, CSLAP, NYC Parks, Suffolk County, individual lakes); >400 lakes/year!
• Sampling conducted mostly by trained volunteers, DEC staff
• Drinking water and most regulated swimming areas (beaches) are the jurisdiction of DOH & State Parks
The DEC HABs Program

The DEC HABs ProgramBloom Status
• Determine bloom status (Suspicious, Confirmed, or Confirmed with High Toxins) based on surveillance (visual evidence) and sampling data
Education• Maintain website with HABs primer, FAQs, photo gallery and
more (on.ny.gov/hab)• Publish articles in DEC publications, respond to press
inquiries, lake association newsletters, etc.• Public presentations and training workshops
Outreach• Daily notifications sent via email to agency and county staff• Weekly updates to website (map), social media, etc.

For all blooms….• Avoid exposure. Keep children and pets away from
scums or discolored water• Seek immediate medical assistance for symptoms
consistent with exposure• Report any symptoms to local/state Health
Department• Report additional and on-going blooms to DEC
through digital photos, suspicious bloom form, or email drop box ([email protected])

NYSDOH Protocol: Visual Evidence of Bloom = Beach Closures & Advisories
• Toxin monitoring is NOT the primary public health intervention
• Lack of bloom for a day ANDanalysis for microcystins required to reopen beaches‒ Method: EPA 546‒ Criteria: EPA, 2017 draft < 4µg/l

42
Visual Based Response: Why?
• Symptoms possible with or without toxins
• Sampling and analysis takes time
• Not all toxins analyzed
• Blooms are dynamic: – Spatial, temporal & toxin gene expression
• Not practical to sample all waters at all times

Public Drinking Water Response
• Triggered by evidence that HABs could be in source water near intake.
• Sample source and treated water• Optimize treatment and reduce levels• Notify public if US EPA Health Advisory Level for
microcystins in small children is exceeded (0.3 µg/l)

• Addresses exposure to unregulated contaminants
• Build in a large margin of protection between observed health effects and level
• An exceedance used to take actions to reduce exposure because the margin of protection is reduced

Examples of Situations Triggering Response • Potentially HAB-related outbreak/illness • Algaecide treatment • Visual blooms near intake• Noted change in raw water quality • Widespread HAB in lake• HAB concentrated near intake• Shallow intake near a lesser HAB• A taste and odor event• Public confidence

Illness SurveillanceReports of recreational and drinking water illness
• Reports from recreational exposures• No reported drinking water illness • Reports of illness coincide with blooms and media attention• Reports from open regulated beaches rare• The numbers of reports are relatively small with potential reporting bias• HAB Illness likely under reported
Federal partners• CDC NORS Reporting• HABISS grant, 2009 (MMWR 2014) • CDC/CSTE Fellowships 2014, 2017 (MMWR 2017)• OHHABS

Selection of Priority Lakes• There are 16,000 lakes in NYS, so a difficult task• Wide variety of types, locations, sizes and
vulnerabilities• All Priority Lakes are water supplies or critical
