How Much Is Soil Testing?

It is possible that while planning to install a septic system, a percolation test will be necessary after your soil evaluation. Simply put, this test further determines the soil’s ability to absorb and filter water, which is essential for the effective functioning of a septic system. 

This test measures the rate at which water drains through the soil. It is conducted by digging a hole in the ground, filling it with water, and then measuring the time it takes for the water to percolate into the soil. The results of this test further help determine the suitability of the soil for a septic system and influence the design and size of the system.

This testing is vital because it ensures that the septic system will function properly without causing environmental contamination or health hazards. Understanding the factors affecting its cost and the importance of hiring a professional can help you make informed decisions and avoid potential issues down the line. 

Factors Affecting Testing Cost 

The cost of testing can vary widely based on several factors:

1. Location: The geographical area can significantly influence the cost due to varying regulations, soil conditions, and market rates for professional services.
2. Soil Type: Different soil types have different absorption rates, which can affect the complexity and duration of the test.
3. Test Depth and Size: The depth and number of test holes required can impact the cost. Larger properties may require multiple test sites.
4. Labor and Equipment: The cost of hiring appropriately licensed professionals and the equipment needed for digging.

Typical Cost Range for Testing 

On average, the cost of testing can be upwards of $1,500. However, in some areas with more challenging soil conditions or stricter regulations, the cost can be higher. It’s essential to get quotes from appropriately licensed service providers to understand the pricing in your specific area.

Steps Involved in Testing 

The basic steps involved in testing include:

1. Site Evaluation: A preliminary assessment of the site to identify the best locations for test holes.
2. Digging Test Holes: Excavating holes of specified dimensions.
3. Pre-soaking: Filling the holes with water and allowing the soil to saturate.
4. Testing: Measuring the time it takes for water to drain from the holes.
5. Analysis: Interpreting the results to determine soil suitability.

Hiring a Professional for Testing

There are several factors to look for when hiring an experienced professional who is properly licensed in your area: 

1. Expertise: Professionals who have the knowledge and experience to accurately conduct the test and interpret the results.
2. Compliance: They will ensure that the test meets local regulations and standards.
3. Efficiency: Professionals who can complete the test more quickly and efficiently, minimizing delays in your project.
4. Recommendations: Based on the test results, they can provide recommendations for the best septic system design for your property.

Always ensure you engage an experienced onsite soil evaluator licensed in Virginia. While most counties follow the state septic regulations, many counties in Northern Virginia have additional local codes that need to be considered and adhered to.
