When it comes to installing or maintaining a septic system, soil testing is one of the most important steps to ensure your system works efficiently and safely. In Ohio, soil testing is required for all new septic systems. But why is it necessary, and what does the process involve? At Supeck Septic Services, we’re here to guide you through the process and ensure your system operates smoothly for years to come through our reliable Septic System Maintenance (O&M) Programs.

What is a Soil Test for Septic Systems?

A soil test evaluates the ground on your property to determine whether it can effectively support a septic system. For homeowners, especially new homeowners, this is a crucial step in understanding how your property will handle wastewater. Septic systems rely on the soil to act as a natural filter, breaking down harmful bacteria and contaminants in wastewater before it returns to the environment. Without a thorough soil test, homeowners risk installing a system on soil that may not drain properly or filter wastewater effectively, leading to potential contamination of groundwater, nearby wells, streams, and other water sources.

For new homeowners, this is especially important since many assume that a septic system will work on any property. Unfortunately, that’s not always the case. If the soil is too sandy, wastewater may drain too quickly, allowing harmful contaminants to seep into the water table before being treated. On the other hand, if the soil is too dense, like heavy clay, it may not drain at all, causing wastewater to back up into the system, potentially damaging your property and creating serious health hazards.

A soil test not only helps ensure that your property is suitable for a septic system, but it also provides critical information about the type of system that’s right for your home. Whether you’re moving into a newly constructed home or purchasing an existing property with a septic system, understanding your soil’s ability to treat wastewater can save you from costly repairs, environmental issues, and compliance headaches down the road. For new homeowners unfamiliar with septic systems, a soil test offers peace of mind and ensures that your investment in a new property is protected for the long term.

Here is what a Soil Tests Looks For:

Soil Composition

The test identifies the type of soil on your property, such as sand, silt, clay, or loam. Each soil type affects how well water drains and how effectively contaminants are filtered. For example, sandy soil drains too quickly to treat wastewater effectively, while clay soil may drain too slowly.

Percolation Rate (Perk Test)

This measures how quickly water moves through the soil. The absorption rate of sand for instance, is going to be completely different than the absorption rate of clay. A septic system needs balance: too fast, and contaminants aren’t filtered; too slow, and the system may back up. That is why this is an important metric for soil testing.

Seasonal High-Water Table

Did you know that the depth of the water table is measured to ensure there’s enough unsaturated soil to treat wastewater before it reaches groundwater?  The ground water level can differ from season to season.  Especially in the great lakes region. Which is why it is required to check the water table.

  1. Soil Depth
    • Adequate soil depth is necessary to properly filter pathogens and nutrients from wastewater.
  2. Site Topography
    • The slope and overall layout of your property are assessed. Steep slopes or low-lying areas may cause runoff or pooling issues, which can lead to system failure.
  3. Presence of Bedrock
    • Bedrock or dense soil layers can block proper drainage, making some areas unsuitable for septic systems.

Why Soil Tests Are Required in Ohio

Ohio law mandates soil testing for all new septic system installations to protect public health and the environment. Faulty septic systems can release untreated wastewater into the ground, contaminating drinking water wells, nearby streams, or lakes. Soil tests ensure your system filters wastewater properly, preventing harmful bacteria and viruses from spreading.

In Ohio, all septic systems must comply with Ohio Administrative Code (OAC) 3701-29, which governs household sewage treatment systems. Soil tests are a key step in the permitting process to ensure your system meets these standards. You can review the laws on our website HERE.

Soil Tests Can find Potential Problems before it Hits Your Pocketbook.

Animproperly placed or constructed septic system can lead to expensive repairs, environmental damage, and even legal penalties. A soil test ensures the system is designed and installed correctly the first time. Older systems did not have this advantage and are often the reason that these systems are such a contributor to pollution.  You can read about that on our blog HERE
