Small communities interested in source water protection across their regional area may be interested in a new program from the team behind SmallWaterSupply.org (SWSO). PrivateWellClass.org is a basic education-focused website funded by the US EPA, in partnership with the Rural Community Assistance Partnership (RCAP). 

The Private Well Class centers on a 10 week email course that teaches homeowners how to properly care for and maintain their water well. This includes introductory information on geology, well contamination and water testing. The site is designed to serve the 45 million Americans who rely on a private well for their drinking water and includes a pre- and post-test quiz to test knowledge improvement.

Understanding how to prevent groundwater contamination, both on the property and via cross-connection control, will be addressed in the lessons as well as during a series of three live webinars.  

Steve Wilson, the project manager at SmallWaterSupply.org and a career groundwater hydrologist, has combined his own knowledge with the vast resources already available on private wells. As with SWSO, the goal with PrivateWellClass.org is to distill the best information into user-friendly content and lessons. 

To date, more than 1200 individuals have signed up for The Private Well Class. Enrollment opened in early December 2012 and the team is actively reaching out to state agencies, extension offices and other organizations that serve homeowners. 

During 2011 and 2012, the U.S. Environmental Protection Agency conducted a series of face-to-face training events for tribal water and wastewater operators. The training sessions emphasized practical, applicable knowledge about operations and maintenance (O&M) as well as asset management.

The materials have been archived into series of interactive, self-paced training modules. Topics for the new training modules include:

• Sewer System Overview 
• Lift Station Overview 
• Overview of Lagoon System Management 
• Decentralized Wastewater Systems 
• Providing and Protecting Potable Water 
• Drinking Water Distribution System Management 
• Storage Tank Management 
• Asset Management 
• Techniques for Developing a Rate Structure 
• Water and Wastewater Operation and Maintenance (O&M) Case Studies

While the content was developed with tribal operators in mind, it is highly applicable to most small or rural systems. The format allows an operator, manager or board member to consume the material on his own time and only the topics that are applicable.

Ohio EPA conducts sanitary surveys at least once every three years at community public water systems (PWS) and once every five years at non-community PWSs. The purpose of a sanitary survey is to evaluate and document the capability of a water system’s source, treatment, storage, distribution, operation and maintenance, and management. Each of these may favorably or adversely impact the ability of the system to reliably produce and distribute water that meets drinking water standards. 

This article is the second installment in a series of articles to help small water systems identify the most common problems found during a sanitary survey or other investigatory site visit conducted by Ohio EPA staff. The first article focused on source water (well) deficiencies. This article will focus on some of the more common treatment equipment deficiencies which are found during inspections of small water systems.  Future articles in this series will cover distribution deficiencies and other topics. 

Backwash discharge lines: If you have a softener or a pressure filter, you backwash your equipment to clean and replenish the media. The waste that is produced when you backwash discharges into a floor drain or another pipe, which carries the waste to where it will be treated.  If the pipe carrying the backwash wastewater from your treatment equipment is too close to, or even inserted into, the drain or pipe that carries the waste to treatment (see Figure 1), you could end up with back-siphonage.

This could occur if the pipe carrying the waste to treatment backs up and the wastewater is siphoned back into your drinking water treatment equipment, contaminating your treatment equipment with whatever waste the pipe is carrying. Solution: Ensure there is a sufficient air gap between the backwash waste pipe and the floor drain or the pipe conveying the waste to treatment to prevent backsiphonage (see Figure 2).

Softener tanks, cover, and salt: Softener brine tanks should be kept in sanitary condition. The brine solution should be kept free of dirt and insects. Solution: The best way to accomplish this is to completely cover the brine tanks with an appropriately fitting lid. The lid should not be over- or under-sized and should be kept in place on top of the tank. Also, the brine tank should not be overfilled such that the lid does not fit snug on the tank (see Figure 3). 

All substances, including salt, added to the drinking water in a public water system must conform to standards of the “American National Standards Institute/National Sanitation Foundation” (ANSI/NSF).  This is to ensure it is a quality product that will not introduce contaminants into the drinking water. Solution: Ensure the ANSI or NSF symbol can be located on the bags of salt you use or ensure your salt supplier can provide you with documentation from the salt manufacturer that it is ANSI or NSF certified. 

Cartridge filters: Over time, cartridge filters will become clogged with iron or other minerals from your source water. When clogged, the filters become a breeding ground for bacteria. Solution: Ensure filters are replaced in accordance with the manufacturers’ specifications or even more often, depending on the quality of your source water.

General maintenance: Water treatment equipment should be accessible and cleaning solutions and other non-drinking water chemicals and materials should be kept away from the equipment. If treatment equipment is not accessible for Ohio EPA staff to inspect during a sanitary survey, it will not be accessible to the water treatment operator for routine maintenance or during an emergency. Likewise, non-drinking water chemicals stored in close proximity to treatment equipment can be an invitation for a mix-up or, even worse, intentional vandalism (see Figure 4). Solution: Keep clutter and non-drinking water chemicals and equipment away from drinking water treatment equipment. Preferably, these items should be stored in a different room.
