Health Risk Associated with Recreation Use of Untreated Surface Water James Howell, DVM, MPH Diplomate, ACVPM State Epidemiologist Indiana State Department of Health
Untreated Surface Water • Ponds, creeks, rivers, lakes, sea shores • Unfiltered to remove protozoa parasites • Untreated with chemicals to destroy bacteria or virus
Viruses of Concern • Hepatitis A • Enterovirus • 29 Coxsackie viruses • 28 Echoviruses • 5 other • Norovirus
Bacteria of Concern • Campylobacter • E. coli 0157:H7 • Leptospira • Salmonella • Shigella • Swimmer’s ear
Parasites • Cryptosporidium parvum • Naegleria • Swimmer’s itch • Acanthamoeba
Toxins • Cyanotoxins are a diverse group of chemical substances that are categorized by toxic effects as follows: • Neurotoxinsaffect the nervous system. • Hepatotoxins affect the liver. • Tumor promoters - chemicals that can increase tumor growth.
Toxins • Cynobacteria • Microcystins - liver, tumor promotor • Saxitoxins - neurotoxin • Anatoxin-a - neurotoxin • Nodularins - liver, tumor promotor • Lipopolysaccharide - inflammation • Cylindrospermopsin – liver other organs
Cyanotoxin Human Health Effects • Skin • Rashes, hives, skin blisters • Inhalation • Runny eyes and/or nose, sore throat, asthma-like syndrome, allergic reactions • Swallowing • Acute and severe gastroenteritis • Liver toxicity • Neurological symptoms
Effects on Pets and Domestic Animals • Drinking contaminated water may cause • Photosensitization • Liver failure • Neurological • Signs and Symptoms • Lethargy, muscle tremors, rapid breathing, • Twitching, paralysis, convulsions • Can cause death
Fish from Contaminated Waters • Shellfishsuch as fresh water mussels can bio-accumulate toxins and should not be eaten • Healthy fish may be eaten,but should exclude liver and kidneys
Bottom Line • Riskof health effects is dose dependent • Higherthe level oftoxinpresent, highertherisk • Skin contact, nasal contact, ingestion • The route of exposure can increasetherisk of health affects.
What a Recreational User Can Do • Wise userstakecertain sensible precautions: • Preparebeforeentering the water: • Bringappropriate gear. • Be sure tocheck weatherconditions • Whilein the water: • Recreate ingroups • Alwayssupervisechildren • Try toavoid consuminglarge amounts of water • When you’refinished: • Make sure youshower • Take time toclean your equipment

Water Quality Issues in the Upper Fall Creek Watershed • 303(d) list of Impaired Waters 2008 • Impairments in the Upper Fall Creek Watershed • E.coli: • Fall Creek-Honey Creek • Fall Creek-Sugar Creek/Deer Creek • Fall Creek-Mud Creek/Little Creek Tributaries • Sly Fork: Brandon Ditch • Minnie Creek Tributaries • PCBs in Fish Tissue: • Geist Reservoir • Fall Creek • Fall Creek/Devon Creek • Mercuryin Fish Tissue: • Fall Creek • Taste and Odor • Geist Reservoir • Algae • Geist Reservoir
Taking Action to Improve Water Quality • Citizen Action: Geist Residents are Organized • IDEM and other agencies work with watershed groups • Central Indiana Water Resources Partnership • Preliminary Report on Water Quality and Nutrient Cycling in the Watershed • Reservoir Research • IDEM Watershed Work
IDEM Work in the Watershed • IDEM Sampling Upper Fall Creek Watershed • 73 sites for: • Nutrients • Metals • Chemistry • 30 sites for pesticides
IDEM Work in the Watershed • An IDEM Watershed Team: • Cross Section of IDEM Office of Water Quality programs including: • Drinking Water • Permits • Compliance • Assessment • Watershed Planning • Purpose: • Review Monitoring Data • Review Permit, Compliance information in the Watershed • Work with Watershed Groups • Propose things we can do to improve Water Quality in the Watershed
Coordination • CEES Monitoring Geist Reservoir • IDEM Sampling Upper Fall Creek Watershed • DNR and ISDH providing information • Organizations and Agencies are Coordinating work to Leverage our knowledge
Going Forward: Ron McAhron
Pilot Project • Established Website: Algae.in.gov • Samples from biweekly Monitoring Mid-May through Mid–October analyzed and posted • Providepublic with Informationabout: • Toxins from Algae • Risks associated with toxins • Precautions you can take • Information from other organizations • Several links to other websites
Conclusion Questions? • Dr. Lenore Tedesco, CEES • Dr. James Howell, Indiana State Department of Health • Bruno Pigott, Indiana Department of Environmental Management • Ron McAhron, Department of Natural Resources
