Understanding Suffolk County’s Updated 2024 Soil Testing Requirements: Your Guide to Compliant Cesspool Installation

If you’re a Suffolk County homeowner considering wastewater system installation or replacement, understanding the county’s stringent soil testing requirements is crucial for ensuring compliance with updated 2024 guidelines. These regulations have evolved significantly to protect Long Island’s precious groundwater resources and coastal environments from nitrogen pollution.

The Foundation of Proper Installation: Soil Evaluation Requirements

Suffolk County’s Department of Health Services mandates comprehensive soil testing as the cornerstone of any wastewater system project. The nature of the soil shall be determined by excavation of one or more test holes or borings at the site of the proposed subsurface sewage disposal system. Test holes/borings must be in the vicinity of the proposed leaching structure(s).

The soil investigation process involves several critical components:

• Test Hole Depth Requirements: The test hole/borings shall be carried to a depth of six feet in excess of the proposed leaching structure bottom or, in the case of unusual soil, until a strata of six feet of sand and gravel is reached (defined as SP or SW by ASTM standards). The test holes/borings shall be a minimum of seventeen (17) feet deep or six feet into groundwater.
• Soil Classification: The soils in a test holes/borings shall be classified using the ASTM Unified Soil Classification System (ASTM D-2487) as a reference.
• Percolation Testing: Percolation testing becomes essential when installing a shallower, eco-friendly alternative to traditional cesspools, especially the innovative nitrogen-reducing I/A systems. It involves simulating the conditions of an active septic system by saturating the soil and measuring the specific layer’s water absorption rate.

2024 Regulatory Changes: What Homeowners Need to Know

Suffolk County has implemented significant changes to combat nitrogen pollution that threatens local water quality. The use of cesspools in new construction has been banned since 1973, and they cannot be used as replacements for old ones. Homeowners are not required to replace their current systems, but if they decide to do so, the new systems must meet the same standards as those established in 1973.

The county’s updated approach includes:

• Registration Requirements: Replacement of existing cesspools and septic systems will require registration of the new system with the Department of Health Services.
• I/A OWTS Mandates: Septic improvement and innovative treatment systems are required in Suffolk County in accordance with new changes passed by Suffolk County Legislature in October 2020. The changes are effective July 1, 2021 and require I/A OWTS to be installed under a number of circumstances.
• Professional Installation Requirements: Contractors hired to replace a system have an obligation to report replacements to the County.

Professional Assessment: Key Factors for System Selection

When planning your wastewater system installation, several critical factors must be evaluated through professional soil testing:

• Test soil type and percolation rates to determine suitability for different systems. Evaluate household water usage, including family size and appliance demand. Consider future property expansions, such as additional bathrooms or irrigation systems.
• Evaluate soil type and drainage patterns to reduce the risk of backups or flooding. Keep systems away from trees with deep roots that could damage pipes. Allow for easy access for maintenance, inspections, and pumping. Consult professionals for guidance on local regulations and setback requirements.

Financial Assistance and Support Programs

Suffolk County recognizes the financial burden of system upgrades and offers support through various programs. The residence must be single-family, owner-occupied year-round, and a property owner’s primary residence. The residence must be served by a septic system or cesspool and not connected to a sewer system or located within a proposed sewer district. Property may not be used as a rental property. New construction is not eligible.

To date, more than 1,900 homeowners have applied for the program, 1,082 grants have been awarded and nearly 600 IA systems have been installed. New York State has awarded Suffolk $10 million in State Septic System Replacement Funds and the county is anticipating receiving a second award of state funding in early 2021.

Environmental Impact and Long-term Benefits

The updated soil testing requirements serve a greater purpose beyond regulatory compliance. Nitrogen pollution from cesspools and failing septic systems is the leading source of excess nutrients in our bays and other natural waters. The pollution introduces too many nutrients into the body of water, leading to algal blooms, fish death, and beach closures.

By ensuring proper soil evaluation and system installation, homeowners contribute to environmental protection while securing their property’s long-term value and functionality.

Moving Forward with Confidence

Understanding Suffolk County’s 2024 soil testing requirements is the first step toward successful wastewater system installation. In the case of unacceptable soil and/or groundwater conditions, inspection of the excavation by a representative of the Department is required prior to the installation of the leaching structure.

Whether you’re facing a system failure or proactively upgrading your property, working with experienced professionals who understand these evolving requirements ensures compliance, environmental protection, and peace of mind for years to come. The investment in proper soil testing and professional installation pays dividends in system longevity, environmental stewardship, and regulatory compliance.
