1 Nonpoint Source Pollution: Car Washings Contribution Karen Alden, MPH Student Walden University PUBH Instructor: Dr. Howard Rubin Spring, 2011

2 Objectives Define nonpoint source pollutants Identify how they enter our water supply Identify responsibility Define the problem Offer solutions

3 What is Nonpoint Source (NPS) Pollution? Natural Human-made Source: Environment Protection Agency (2010). What is nonpoint source pollution? Retrieved from on April 15, 2010.www.epa.gov/owow_keep/NPS/whatis.html

4 How do NPS pollutants enter our water supply? Source: Environment Protection Agency (2010). What is nonpoint source pollution? Retrieved from on April 15, 2010.www.epa.gov/owow_keep/NPS/whatis.html Crucial Car Pollutants Toxic Cleaning Solutions Polluted Wash Runoff Storm Drains Ashuelot/Connecticut Rivers

5 Our Responsibility! United States 25% of U.S. population are chronic car washers 27 million potential residential car wash polluters Keene Equivalent to 5,852 potential residential car wash polluters Source: S.

7 The Problem with Residential Car Washing 55-70% of households wash their cars at home 60% of residents at least once a month 70-90% of residents indicated the car wash water drained into the street.

8 The Problem with Car Wash Fundraising 2,000-7,000 gallons of water/event (2002) A single event equivalent to a 6,000 gallon sewage spill. Collectively equivalent to 23 Exxon Valdez oil spills/yr in the continental U.S. (2002) Source: New England Car Wash Association (2009). Answers to consumer questions about car washing.

9 The Pollutants Crucial Pollutants Petroleum hydrocarbon waste Gasoline, diesel, motor oil, fluids, lubricants Nutrients Phosphorous and nitrogen Ammonia Surfactants Solids Source: City of Federal Way Public Works Dept./Surface Water Management Division (2009). Residential car washwater monitoring study.

10 What Harm Do These Pollutants Cause? Petroleum hydrocarbon waste Highly toxic Harm through contact, ingestion, destruction of ecosystem Quantity toxic substance/Affected Surface Area Ratio Nutrients Promotion of eutrophication Promotion of algal blooms Source: City of Federal Way Public Works Dept./Surface Water Management Division (2009). Residential car washwater monitoring study.

11 What Harm Do These Pollutants Cause? (cont.) Ammonia Toxicity to fish Surfactants Toxicity to aquatic life Solids Most common pollutant Decrease suitability for humans and aquatic life Source: City of Federal Way Public Works Dept./Surface Water Management Division (2009). Residential car washwater monitoring study.

12 Car Washing Pollution Solutions Prevention Pollution Program Development Residents Charity Organizations Car Wash Businesses Containment Equipment Available Catch-basin insert with sump pump Vacuum/boom device Bubble Buster
