Well Water Contamination from Septic Systems

Blog Post - septic manhole cover.png

Many homeowners who use a septic system to provide wastewater treatment for their home often get their drinking water from a private well. If the septic system is malfunctioning or happens to be located too close to a drinking water well, contaminants from the wastewater can end up in drinking water. Learn how to locate, operate, and maintain your septic system to protect nearby wells and preserve the groundwater. Your septic system could contaminate your drinking water well or a nearby well under certain conditions, so it is important to regularly test the drinking water from your well (once a year is recommended) and take corrective action as needed.

Water from your toilets, showers, and other appliances contains harmful bacteria, viruses, and nutrients that could make you sick if it were to enter your well without being properly treated first. Maintenance issues like a full or cracked septic tank or a plugged drainfield can cause untreated wastewater to enter the surface water or groundwater. 

According to U.S. EPA: "Filtering wastewater through the soil removes most bacteria and viruses (also known as pathogens) and some nutrients. While soil can treat many contaminants, it cannot remove all of them (e.g., medicines, some cleaning products, other potentially harmful chemicals). If untreated wastewater surfaces in the yard, wastewater may contaminate your drinking water through an unsecured well cap or cracks in the well casing. It’s important to avoid flushing medication and chemicals into your wastewater since it could contaminate your drinking water."

The contamination risk to your well is lower the farther apart the well and septic system are located, the deeper the well is placed (and if it is in bedrock or below a defined layer of silt or clay,) or when your septic system is pumped and serviced on a regular basis.

The contamination risk to your well is higher if the well is at a shallow depth and in permeable soil, if the groundwater flows from the septic system towards the well, if there are many homes on septic systems near the well, or if there is poor construction or maintenance of the well and/or septic system.

Of course, there are a number of factors that can contribute to well contamination, from human mistakes and interference to natural groundwater chemistry. This video from our sister site, PrivateWellClass.org, discusses the basic circumstances that can lead to contaminated well water, and the kinds of naturally occurring contaminants that can be found in private wells.

Featured Webinar: Alternatives to Traditional Onsite Wastewater Systems

Blog Post Template - Alternatives to Traditional Onsite WW Systems.png

This hour-long webinar recording from the Rural Community Assistance Partnership (RCAP) focuses on alternatives and advancements in traditional onsite wastewater systems and their unique applications and uses, including constructed wetlands, cluster systems, package systems, mound systems, etc. 

Alternative/ Innovative Onsite Wastewater Treatment Options:

Constructed Wetlands: A form of secondary or tertiary wastewater treatment that can be used by large municipalities and single-family homes alike. It is an organic wastewater treatment system that mimics and improves the processes that help to purify water in the same way as naturally occurring wetlands. This option uses water, aquatic plants, naturally occurring microorganisms, and a filter bed (containing sand, soil, and gravel.) 

There are two types of constructed wetlands: Surface Flow and Subsurface Flow wetlands. Surface Flow wetlands resemble natural wetlands in looks and the way they provide treatment. They are more economical for large volumes of wastewater. Subsurface flow wetlands are the most common type of constructed wetlands to treat household wastewater onsite.

Cluster Systems (also known as Community Systems): A decentralized wastewater treatment system under common ownership and collects wastewater from two or more dwellings or buildings. Cluster systems convey wastewater to a treatment and dispersal system located near the dwellings. These can be as simple as a subsurface disposal field served by individual septic tanks, or as complex as a neighborhood collection treatment and disposal system. 

Cluster systems transport wastewater via alternative sewers to either a conventional treatment plant or a pre-treatment facility followed by soil absorption of the effluent. The advantages of a cluster system are the shared costs with installation and future maintenance, but the disadvantages are undefined ownership and making sure everyone involved observes their responsibilities.

Pressure Manifold System: Uses pressure to distribute effluent in a more even, measured dose. Good for overcoming limitations of distribution boxes. Level manifold systems for effluent to flow equally via gravity. Sloped manifold systems have lateral trenches at various elevations to ensure that all branches operate at equal pressures.

Low Pressure Dose System (LPD): An anaerobic septic system with addition of a pump tank. Advantages with this option are that it can be installed in heavy clay soils, and it reduces the amount of land area required by the drainfield. Disadvantages include potential infiltration by roots, clogging of drain hose by solids, and wastewater accumulation in the drainfield. This system is not a viable option if water table is detected.

Drip Distribution system: Provides effluent dispersal that can be used in many types of drainfields. This alternative disperses treated septic water over a greater surface area of land. It irrigates the field with long flexible tubing that maximizes the treatment of sewage and minimizes the risk of untreated wastewater flowing too quickly through the soil. No large mound of soil is needed. This option requires a large dose tank to accommodate the time dose delivery of wastewater to the drip absorption area. A potential disadvantage of this method is that it needs electrical power which comes with increased maintenance and extra expenses.

Chamber System: This alternative contains no gravel in the drainfield. Instead, the drainfield is made up of synthetic chambers with bases that are open to the ground to allow effluent to drain into surrounding soil. Advantages with this method are increased ease of delivery and construction, they offer a large wastewater treatment volume, and it's good for areas with high water tables. Disadvantages are that this option will be expensive to install if the site has lots of gravel and sand, and this system could pollute the water table if the soil in the area has a high absorption rate.

Evapo-transpiration System (ET): Provides onsite wastewater treatment and disposal. Can dispose of wastewater into the atmosphere through evaporation from the soil's surface and or transpiration by plants. This option offers flexibility with the combination of seepage and evaporation, has a low risk of groundwater contamination, and it can overcome site, soil, and geological limitations that may come up. It is not suitable where land space is limited, or the surface is irregular. This alternative is only useful in arid climates with adequate heat and sunlight (it can fail if it rains or snows too much.)

Mound System: Good for areas with a shallow soil depth, high water table, or shallow bedrock. This method requires substantial amounts of space and periodic maintenance. Trees must be removed or cut back, and sand must be brought in to build the mound. This alternative can be expensive to install. 

Sand Filter: Provides a high level of treatment for nutrients and is good for sites with high water tables or are close to water bodies. With this option, treated water can pass directly from the sand filter to the soil without needing to pass through a leach field. 

Traditional approaches to onsite wastewater treatment are useful in many circumstances, but innovative alternatives are often the best choice for any unique situations that may arise. The alternatives to conventional septic systems mentioned above allow for cost-effective, long-term solutions if a traditional septic system is causing water quality problems.

Protecting a Septic System During and After a Flood

Blog Post - Septic Flooding.png

When a home or the area surrounding it floods, the septic system is at risk of becoming waterlogged. This could be from a leak in the lid, rising groundwater that enters into the system, or an over-saturated drainfield that can't properly drain. A flooded septic system may lead to sewage backing up into the home and cause serious problems for the homeowner. 

Septic tanks may not always experience damage just because there is flooding, but any existing leaks in the system will allow floodwater, silt, and debris to enter the system. This presents a big problem since the extra dirt and debris can cause clogging. Extra water entering the septic system can also cause the floating solids to rise up and plug the pipes. The U.S. Environmental Protection Agency has information on what to do after a flood to ensure your septic system is protected. Below we have summarized this information with a list of dos & don'ts:

Septic System Flooding Dos & Dont's

Do! Don't!
Conserve water as much as possible Don't drink well water until it is tested
Cut back on showers, laundry, running the dishwasher, and flushing the toilet Don't compact the soil over the drainfield by driving heavy machinery over the area
Clean affected areas within the home with a solution of 1/2 cup bleach to 1 gallon of water if there are backups Don't use the system until water in the soil absorption field is lower than the water level around the house
Have the system professionally inspected and serviced if there is suspected damage Don't attempt to clean or repair the septic tank yourself
Ensure the manhole cover is secure and inspection ports have not been blocked or damaged Don't open the septic system for pumping while high groundwater conditions remain
Pump both the tank and the lift station as soon as possible after the flood subsides Don't dig into the tank or drainfield area while the soil is still wet
Examine all electrical connections before restoring electricity to the area Don't clean up floodwater by dumping it into the sink or toilet

 

This video provides some additional tips for how to avoid septic tank flooding and what to do if your system does flood:

 

Following these tips will help septic system homeowners to be prepared in the event of a flood and protect the septic system from further damages. If you need more specific advice or assistance with your septic system, contact your local health department for a list of septic system contractors in your area.

Surprising Facts About Septic Systems

Blog Post Template - Septic.png

Septic systems treat and dispose of wastewater for locations that public wastewater systems do not service. Many homeowners living with a septic system don't know much about it other than the fact that they have one. If more homeowners learned the ins and outs of their septic systems, they would have the ability to prevent issues before they arise. This article from Dano's Septic (excerpted below) reveals some surprising facts about septic systems.

Every home has a different pumping schedule

  • Septic systems must be maintained regularly (at least once every 3-5 years) but the exact frequency depends on some factors like tank size, system age, and usage habits.

You can't flush everything

  • Flushing items like pet waste, feminine products, and even floss can interfere with the system's ability to break down waste and create the need for premature pumping of the system.

Drain cleaners can be dangerous

  • Chemical drain cleaners can mess with the balance of your septic tank and create problems down the road. Avoid this "quick fix" whenever possible and call a professional to help unclog any drains.

The system involves much more than just the toilet and tank

  • Every single sink, tub, and pipe in the home is connected to the septic system. Even the garbage disposal can affect how the system functions, so it is important to pay close attention not only to what is being flushed down the toilet, but also what is poured down the drain.

Your system can affect the groundwater

  • Septic systems have the potential to contaminate the groundwater since whatever enters the septic tank will eventually reach the drain field and seep into the ground.

Drain fields can flood

  • This is one of the biggest concerns related to septic systems. When the drain field floods, it quickly contaminates the property with wastewater. Try to practice water conservation as often as possible and schedule a professional inspection annually to prevent this.

Maintaining your system will extend its lifespan

  • Septic tanks can last for decades with consistent upkeep but eventually they will need to be replaced. Prioritize repairs and maintenance for the septic system to ensure the longest lifespan possible.
When homeowners have a strong understanding of how their septic system functions, they are able to maintain it and prevent issues from prematurely surfacing. When a septic system is well maintained, it can last the homeowner for years to come.

Developing a Septic System Owner's Guide

Blog Post Template - Septic1.png

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
