1 Tammy Klemens & Darla Topp, Kent State University Stark Campus, North Canton, Ohio, USA What’s the Stink About Sewage?

2 Septic Systems and Sewage Treatment Plants in Stark County and Their Effect on the Environment.

3 What is sewage?  Sewage is liquid and solid waste carried off in sewers or drains (American Heritage Dictionary 2006).  Often referred to as wastewater, blackwater (Sustainable Build), water reclaimed water, sewer sludge or effluent (WordNet 2006). Background Information

4 Sewage Treatment Options  City or county sewage treatments plants.  Individual septic systems.  Wastewater or sewage drainage into lakes, rivers or streams. Background Information

5 Government Controlled Sewage Treatment Systems (Brain 2000)  Wastewater is collected and carried to sewage treatment plants via the sewer main.  Gravity carries the wastewater most of the way. Lift stations can be used to move waste up a hill.  Sewage can be treated in three separate stages.  Primary treatment removes up to 50% of solid wastes.  Secondary treatment removes up to 90% of solid and organic wastes using bacteria and aeration.  Tertiary treatment uses chemicals and filter beds to kill remaining bacteria. Background Information

6 Septic Systems (T.E. Griffith)  Effluent is discharged to the main holding tank.  The solid waste sinks to the bottom as sludge and grease and partially decomposed matter floats on top.  The middle layer is composed of mostly water that is discharged into the leach beds for filtration.  Bacteria decomposes the sludge.  Septic tanks need to be professionally cleaned out every one to two years or the system will fail.  New systems cost between $4500 to $20,000 Background Information

11 Global Issues  2.6 billion people, or 40% of our population, do not live with adequate sanitation (CDC 2008).  Approximately 90% of sewage in developing countries is discharged directly into rivers and streams (Revenga and Mock, 2000).  The UN estimates that 5.2 million people, 4 million being children, die from diseases carried by untreated wastewater each year (UTS 2002).  Diarrhea, cholera, typhoid fever and hepatitis A are some of the diseases that can be contracted from contaminated wastewater (CDC 2008).  Certain combinations of chemicals discharged in sewage can produce an estrogen effect in fish, causing the males to develop eggs in their testes (Rachel’s Environment & Health Weekly). (Cosmos 2006)

12 Types of Pollutants Ravenga and Mock 2000)

13 National Issues  The US pipes 50 trillion gallons of raw sewage to be processed by 20,000 different plants (Pegg 2004).  Some of these pipes are 200 years old and are failing. It could cost up to $1 trillion dollars to fix the sewage infrastructure (Pegg 2004).  In 2001, the EPA found 40,000 sewer backups and 400,000 backups of raw sewage into basements (Pegg 2004).  1.8 to 3.5 million people get rashes, respiratory infections and diarrhea from swimming in sewer contaminated waters (Pegg 2004).  Blended flow allows excess sewage to bypass treatment, mix with treated water and flow into rivers and streams carrying contaminates (Pegg 2004).  In 1996, researchers found that male fish living downstream of up-to-date U.S. sewage plants also had the estrogen effect (Rachel’s Environment & Health Weekly).  1 in 4 American households use septic systems, many of which are failing (EPA 2009). (MSNBC 2009)

14 Regional Issues  Lake Erie provides drinking water to 11 million people (Gamberg 2007).  10.9 billion gallons of raw sewage was dumped into Lake Erie in 2005 (Gamberg 2007).  Lake Erie swimmers who completely immerse themselves in the water are 40% more likely to become ill (Gamberg 2007).  2000-2005, Lake Erie’s water samples had unsafe E. coli levels in 1 out of 6 tests (DutZik and Gomberg 2006).  The Ohio EPA does not regulate septic systems, local health departments do (Ohio EPA).

15 Questions Main question  In Stark County, Ohio, are septic systems or wastewater treatment plants more harmful to our environment? Sub-questions  What are the conditions of our local sewage infrastructure?  Are repairs being made if the infrastructure is failing?  Are there any diseases or illnesses attributed to our wastewater treatment systems?  If there are problems, what actions have the local government institutions made to correct the problem?  Are the septic systems in Stark County in compliance with state health regulations? ? ? ? ? ? ? ? ?
