Lead and Copper Pipe Replacement

Lead and copper enter drinking water primarily through plumbing materials. Exposure to lead and copper may cause health problems ranging from stomach distress to brain damage. The treatment technique for lead and copper requires systems to monitor drinking water at customer taps. If the action level for lead is exceeded, the system must also inform the public about steps they should take to protect their health and may have to replace lead service lines under their control.

We have 521 resources (and counting) on Lead and Copper in our Documents Database that provide valuable information on this topic. You can search for documents on how to collaborate with organizations to replace lead service lines (LSLs), case studies that analyze LSLs in small community water systems, how to reduce lead in drinking water in schools and childcare facilities, how to address lead in drinking water with the Drinking Water State Revolving Fund (DWSRF), and many other useful guides that will help you to deliver safe and clean water to utility customers.

Winter Maintenance for Septic Tanks

In the winter months, septic tanks are vulnerable to damages caused by lower temperatures and excessive snow. The biggest concerns being snow build up and lack of protection from cold temperatures. If your septic tank is located in an area where vehicles can drive over it, watch out for compacted snow that can push it deeper into the system. Fluid that lingers in poorly installed or deteriorating pipes, plumbing leaks, and long periods without using your septic system can all cause it to freeze. 

Your septic system may suffer damages if you do not provide adequate cover like an insulating cover/ blanket. These will help to trap heat inside the system and prevent it from freezing inside. Other ways to help prevent your septic system from freezing are to regularly pump your system (every 3-5 years) before winter, don't dispose of inappropriate waste down toilets or drains, use insulated pipes, and remove trees or plants with strong root systems from on top of your septic system to prevent root interference with the system.

Things to keep in mind when working in extreme cold:

• Wind Speed: high wind speeds can create a wind chill effect which makes it feel a lot colder than the reported temperature states.
• Humidity: humidity will cause heat to be conducted from the body much faster than if you are working in dry air. 
• Hypothermia: without proper protection, hypothermia can become a concern when the air temperature drops below -23 degrees Fahrenheit.
• Frostbite: exposed skin can freeze in 5-10 minutes when temperatures reach -40 degrees Fahrenheit.
• Ice & Snow: ice can freeze your equipment and the weight of snow can collapse structures you may be working in or under.

Always bring extra clothing and try to find a place to warm up when working in extremely frigid conditions. Be sure to remove excess snow from work areas and store your equipment under tarps or in heated areas.

Groundwater Rule Compliance

The groundwater rule is to reduce disease incidence associated with disease-causing microorganisms in drinking water. The rule establishes a risk-based approach to target groundwater systems that are vulnerable to fecal contamination. Groundwater systems that are identified as being at risk of fecal contamination must take corrective action to reduce potential illness from exposure to microbial pathogens. The rule applies to all systems that use ground water as a source of drinking water. 

We have 488 resources (and counting) on Groundwater in our Documents Database that provide valuable information on this topic. You can search for resources on the Ground Water Rule (GWR), public water well maintenance and use, compliance monitoring for GWSs, effective well maintenance and procedures, and many other useful guides that will help ensure our groundwater stays safe and clean for generations to come.

Developing a Septic System Owner's Guide

The Community Septic Owner's Guide online tool is designed to develop an Owner's Guide for everything from a single-family home, a commercial property, or even a cluster system serving 50+ homes. It was funded by the USDA National Institute of Food and Agriculture and created by the University of Minnesota. Some key things to keep in mind about this tool are:

• You will need to register if you are using the tool for the first time
• It contains generic stock/boiler plate general information, system component descriptions and images, and operations and maintenance (O&M) recommendations
• It allows you to upload site specific descriptions, images, and O&M recommendations
• It will produce a PDF guide for your home or structure to be used electronically or printed out
• It allows you to start and stop a project during the process and update it years later when things change
• It does NOT cover every scenario that exists across the US, but the creators of the tool hope it covers a vast majority of them

Financial Management for Small Water Utilities

Many small public water systems lack organized finances, with little to no budgeting or accounting, no long-term financial planning, and customer rates that are not adequate to cover expenses. Many small systems also need expensive repairs or upgrades that would be difficult to afford even if they had impeccable book-keeping. In recognition of this, the federal government and many national organizations provide small systems with resources to organize and improve their finances, as well as grants to help fund major projects.

We have 1712 resources (and counting) on Financial Management in our Documents Database that provide valuable information on this topic. You can search for documents on funding opportunities to build system resiliency, building a financially healthy water system, how to use the Drinking Water State Revolving Fund (DWSRF) to mitigate the impact of drought on drinking water systems or to address DBPs in drinking water, and many other useful guides that will help you to deliver safe and clean water to utility customers.

Drinking Water Standards: Rules, Regulations, Compliance

The U.S. Environmental Protection Agency (EPA) sets standards that, when combined with protecting ground water and surface water, are critical to ensuring safe drinking water. U.S. EPA works with its regional offices, states, tribes and its many partners to protect public health through implementing the Safe Drinking Water Act. The standards are the levels of a particular contaminant that are allowed in drinking water and still considered safe.

We have 1482 resources (and counting) on Drinking Water Standards in our Documents Database that provide valuable information on this topic. You can search for resources like an overview of the Safe Drinking Water Act (SDWA), information on how U.S. EPA develops risk-based drinking water regulations, a comprehensive list of potential contaminants in water, and many other useful guides that will help you to deliver safe and clean water to utility customers.

Trying out the New Onsite Wastewater Treatment System Assessment Tool

Through funding from U.S. EPA, a team at the Illinois State Water Survey with the help of NOWRA and RCAP developed the new Onsite Wastewater Treatment System assessment tool (OWTS tool). The OWTS tool was created as a companion to the Well Assessment Tool, which has been utilized by RCAP’s Technical Assistance Providers (TAPs) and other health professionals to help people across the nation evaluate their private wells.

The OWTS tool allows the assessor to collect contact information, landscape and geology details, and general information about the system and house. There is a checklist for site observations as well as miscellaneous questions to make sure you fully understand how the system is being used.

Once the OWTS tool was finalized, Steve Wilson and Sallie Dolan from our WaterOperator.org team headed out to perform some OWTS and well assessments. The first stop was close by in Piatt County. The homeowners have only lived in the house for a year and a half, so they were curious to learn as much as they can about the well and OWTS. 

The well was of good construction and had no obvious issues. It did have to be shocked with chlorine prior to them moving in, so we recommended they have the water tested for bacteria, nitrates, and that they have a broad panel test done. The home has a water softener and charcoal filter, but the homeowners did not know why they were added to the system. Identifying what metals, minerals, etc. are in the water will help them understand why they have these components.

The OWTS is in the backyard which slopes to a floodplain of the small drainage ditch/creek that runs along the northside of the property. It consists of a Delta Whitewater aerobic tank with chlorinator. The discharge pipe delivers the effluent into the creek floodplain. The homeowners have planted native wetland plants in the area which helps prevent water from standing and beautifies the area.

The 50-gallon tank had to be pumped within the first six months of them living in the home. The homeowners switched to septic-friendly toilet paper and learned the dos and don’ts of what goes into the system, yet it needed to be pumped again less than a year later. The previous owners reported that they never had a similar problem.

Three bedrooms and a family room are in the walk-out basement. Sallie’s theory is that moving trucks drove across the pipe while accessing the walk-out basement during move in. This would have caused the pipe to break and allow sediment to flow into the tank. We are hoping to be on-site when the system is scoped to see if this theory is correct.

The second home we visited was to our east in Vermilion County. The homeowner explained that a “wetland” had formed at the edge of his property which was full of leopard frogs. When we pulled up driving directions on Google maps, we knew that there was an issue with the system. The satellite image clearly showed the outline of a septic tank with lush, green grass growing in three lines while the rest of the yard was brown and dry. The homeowner had already acquired the sewage permit, and the as-built drawing matched up perfectly with the lines on the Google maps image.

The assessment revealed that the homeowner had built a two-bedroom addition to the house soon after it was purchased, taking it from a four-bedroom home to a six-bedroom one. Both homeowners work from home most days, they have three children who live at home, and older children who visit frequently. The “wetland” was an area of lower elevation just beyond the drain field where water from the system was pooling. We recommended that an OWTS installer who is registered with the local health department be contacted to determine if the system is now undersized for its current use. 

At first, the well log for this property could not be located. Luckily, the manager of the well and sewage programs at the local health department knew the site and was able to find the log for us. The well was a bored well with a buried slab. A 6-inch casing was placed from 12 inches above the surface to 28 feet deep, and then a 4-foot well was bored from 28 to 52 feet. According to the well log, it is topped with 28 feet of clay, which helps protect the well from surface water contamination. We also recommended that the soil be sloped around the well head to help protect it. Annual testing for coliform and nitrates is highly advised as they are indicators of potential contamination.

In both cases the assessment did its job to help identify areas of concern with the onsite wastewater treatment systems. The homeowners are more informed and can now take the next steps to contact a professional pumper/installer to help correct any issues found. 

The OWTS and well assessment tools can be found on our sister site, PrivateWellClass.org.

If you would like an assessment done on your well and/or OWTS, contact your local RCAP office.
