Environmental Testing

The Fishers Health Department vector control program primarily targets mosquitoes and rodents. We also closely monitor rabies through the county animal control ordinance and animal bite reporting.

The Fishers Health and Water Quality programs provide open water testing information for 40 creek and open water locations they test. 9 area results are published monthly during spring, summer and fall. See explanations of what we test and the results below.

Water Temperature  

Aquatic organisms thrive in warmer water and bacteria grows faster at higher temperatures. Higher temperatures combined with sediment from agricultural waste or leaking septic tanks during a rain event can increase the pathogenic bacteria levels such as E. coli. Fishers has both urban and agricultural runoff inputs into the watershed which affects our water quality. Learn more.  

Dissolved Oxygen (DO)  

DO is essential for aquatic life. Low levels of oxygen (hypoxia) or no oxygen (anoxia) can occur when excess organic materials, such as large algal blooms, are decomposed by microorganisms. During this decomposition process, DO in the water is consumed. Low oxygen levels often occur in the bottom of the water column and affect organisms that live in the sediments. In some bodies of water, DO levels fluctuate periodically, seasonally, and even as part of the natural daily ecology of the aquatic resource. As DO levels drop, some sensitive animals may move away, decline in health or even perish (U.S. EPA). Moving or flowing water, like streams, tend to have more DO than a lake or pond. Details.  

  

E. coli  

Wherever you have humans or wildlife in contact with water, you have the potential for waterborne disease. Since E. coli is a naturally occurring bacteria found in warm-blooded animals, it is used as an indicator for other harmful bacteria and viruses in the water environment. Humans naturally affect water quality by land use practices (agricultural, residential, wastewater etc.), recreational use (swimming, fishing, boating etc.), and drinking water withdrawal and treatment. Major waterborne diseases include dysentery, Hepatitis A and bacterial and viral gastroenteritis (E. coli). Monitoring for these bacteria is a vital component to public health. While fecal coliform, E. coli, does not necessarily cause disease, it is an indicator of disease-causing organisms. Learn more.  

  

Algae  

We are not able to test for Algae. IDEM is one of the few locations that do, but they are only able to test in designated state locations. Citizen’s Water does test different types of algae and have agreed to notify Fishers Health Department in cases of problematic concerns. Notification will be made at that time.

Public Notice    

Frequent unsatisfactory levels at Geist Park and White River are a result of our waterways being in the Upper White River Watershed.  We receive both urban and agricultural run-off during high rain events. Besides the farmland and older septic systems upstream, our urban and suburban expansion areas are rapidly increasing making it particularly susceptible to anthropogenic influences related to both agricultural practices as well as effects of urbanization (IUPUI). Surface waters are directly affected by these various sources of contamination carrying E. coli into the watershed. The more vegetated areas with grasses tend to soak up rainfall, directly increasing infiltration into the ground and reducing run-off into our recreational waterways. Land that has been developed with streets, roof tops, sidewalks, driveways, and parking lots are impervious and create run-off into storm drains that eventually lead to our waterways. In the agricultural areas, run-off can come from fields and animals. Heavy rain events wash manure from land into the waterways. An increase of E. coli is generally seen after these rain events as well as when water temperatures rise. E. coli is adapted to living in the intestines of warm-blooded animals, so it naturally thrives in warmer temperatures. Point source discharges such as septic system failures, storm water outfalls and wastewater treatment plant overflows also directly input E. coli into recreational waterways.    

We added an additional water sampling location on Fall Creek as it enters the reservoir east of the Olio bridge, (Fall Creek at Canal Place).  Here we are better able to compare water quality as it enters the reservoir. We again test it at the Olio Road boat ramp as it flows south further into the reservoir, along with added samplings in “Family Cove” and “Cambridge Cove”. These samplings will have direct relation to where we find most relaxing in the water.     

  • Monitoring: We actively track the presence of West Nile Virus and other vector-borne diseases through a phased approach by sampling various city locations, analyzed by the Indiana Department of Health lab.  
  • Response: Upon positive findings, we inspect public areas for standing water. Detected water sources are treated with VectoMax FG, a safe and efficient mosquito larvicide applied as dust-free granules. We don’t use sprays due to potential health concerns.  
  • West Nile Virus: Active during late summer and early fall.    

Preventing Mosquito Bites:  

  • Use insect repellents outdoors.  
  • Wear long sleeves and pants during dawn/dusk.  
  • Ensure screens on windows and doors are intact.  
  • Use air conditioning during peak mosquito times.  
  • Eliminate mosquito breeding spots like trash or water-collecting areas.  

The Fishers Health Department addresses rodent complaints on public properties or areas affecting the public. After receiving a complaint, we will conduct an inspection and assess the need for further action. We do not perform routine pest management for private residents. For rodent prevention tips, please contact us.  

File a Complaint  

Residents and businesses can submit a complaint to the Fishers Health Department.  

Resources  

The Fishers Health Department recommends certified laboratories be used for well water testing. For a list of Indiana Certified Drinking Water Laboratories, visit the Indiana State Health Department. (The Fishers Health Department does not endorse any laboratories and this list is an information tool. Water samples from certified laboratories not listed are accepted by the Fishers Health Department.) 

Water samples occasionally return unsatisfactory and may require additional disinfection. See IDEM well disinfection procedures

Submit weekly pool samples

 

The Fishers Health Department does not typically evaluate owner-occupied housing for mold or indoor air quality issues. Renters should work with their landlords and within the terms of their lease to ensure issues are addressed. Please reference Indiana Code 16-20-1-23 for standards. 

There are currently few rules or regulations that can be enforced concerning Indoor Air Quality, other than those that have been promulgated for Schools and State Agencies (410 IAC 33). For more information, visit the Indiana State Department of Health’s website
