SEVIEW 8.0 PFAS

Transport and Fate Modeling

ESCI is thrilled to announce the release of SEVIEW 8.0, a groundbreaking program that revolutionizes PFAS modeling in soil and groundwater. SESOIL 8.0 differs from similar modeling software in that it simulates the adsorption of PFAS to the air-water interface in the unsaturated zone. ESCI has worked with government agencies and environmental consultants to develop SEVIEW 8.0. It marks a significant leap forward in PFAS modeling, offering features and capabilities not available in competing programs. Modifications to SESOIL were validated using measured site data. SESOIL modeling indicates that PFAS can be substantially retained in the unsaturated zone. Indicating that leaching PFAS contamination is an issue that regulatory agencies will likely face for many years to come. PFAS Modeling Per- and polyfluoroalkyl substances (PFAS) are used in a wide range of products and industrial processes, leading to their widespread presence in the environment. Studies have established a link between PFAS exposure and serious health concerns, such as birth defects and cancer. Known as “forever chemicals,” they are concentrated in sewage sludge, which can be applied as fertilizer on agricultural fields. PFAS have also been used in firefighting foam at military installations, airports, and firefighting training facilities. When released to the surface, PFAS can seep into the soil and contaminate groundwater. Reports of PFAS in groundwater have highlighted the importance of unsaturated soil zone modeling when evaluating risks to groundwater quality. The mobility of PFAS is dependent on water saturation, causing them to migrate differently from other more commonly known contaminants. This makes PFAS modeling in the unsaturated zone uniquely challenging. SEVIEW 8.0 SEVIEW 8.0 was designed to be the ultimate modeling experience. It is the most powerful and capable version of SEVIEW ever. With enhanced versions of SESOIL and AT123D — this is modeling software without equal. From integrated model setup to graphical reports, it raises the bar for modeling. Combined with the climate, chemical, and soil databases, SEVIEW contains everything you need. The capabilities of SEVIEW 8.0 let you reimagine what is possible with analytical modeling. Advanced features allow you to perform modeling in ways you never imagined, enabling you to complete your modeling projects faster and with unprecedented ease. SESOIL and AT123D SEVIEW 8.0 maximizes the capabilities of the SESOIL and AT123D models. Whether you are developing soil standards protective of groundwater quality, or performing groundwater modeling, SEVIEW has you covered. With SEVIEW you can run complex simulations that previously required numerical models such as MODFLOW and MT3D. Something that other analytical programs cannot do. New to version 8.0: PFAS Modeling Updated chemical database. Updated soil database Our SEVIEW modeling software has been used by numerous state regulatory agencies to develop baseline soil cleanup objectives. To ensure adequate protection of groundwater quality their default cleanup objectives are based on the worst-case scenario. Application of such conservative cleanup concentrations may result in costly remedial actions that may not be warranted. Environmental consultants can use SEVIEW to develop site-specific soil impact to groundwater remediation standards. At most sites this will reduce cleanup costs while maintaining protection of groundwater quality. At other sites it may indicate that a threat to groundwater quality exists. Three Versions of SEVIEW 8.0 Start by choosing the version that fits your needs. You have a choice between SEVIEW Basic, Basic+, or Pro. All versions include the SESOIL and AT123D models, along with the climate, chemical, and soil databases. Even the project files are compatible with all versions of SEVIEW. The only difference is the number of sources that can be simulated. By offering three versions you do not need to spend money on features you are not using. If your needs change, you can always upgrade at a later date. Basic One Source: Basic includes everything needed to simulate contaminant migration in soil and groundwater. For most modeling projects this is all you need. Use SESOIL to simulate contaminant migration in soil. Then link SESOIL to AT123D to determine groundwater concentrations. Or use AT123D on its own to perform groundwater modeling. SEVIEW 8.0 Basic meets the requirements of the New Jersey Department of Environmental Protection guidance on "Using the SESOIL Transport Model to Assess the Impact to Ground Water Pathway", December, 2008. Basic+ Two Sources: Basic+ offers the next-level in capabilities. It includes everything needed to simulate contaminant migration in soil and groundwater for two sources. Use SESOIL to simulate contaminant migration in soil. Then link SESOIL to AT123D to determine groundwater concentrations. Use the second source to simulate an existing AT123D groundwater plume. This capability goes beyond other programs and is only available in SEVIEW. SEVIEW 8.0 Basic+ meets the requirements of the NJDEP guidance on "Using the Combined SESOIL/AT123D Models to Develop Site-Specific Impact to Ground Water Soil Remediation Standards for Mobile Contaminants", Version 2.1, May, 2014. Pro 15 Sources: Pro provides the capabilities to take on the most demanding projects. It pushes the boundaries of what is possible. It includes everything needed to simulate multiple contaminant releases in soil and groundwater in a single run. Mix and match up to 15 different SESOIL or AT123D sources. This feature can be used to establish on-site verses off-site contributions and to evaluate various remedial alternatives. Previously this capability only existed in numerical models such as MODFLOW and MT3D. SEVIEW Pro brings the capabilities to tackle almost any site.

Our comprehensive software

packs everything you need to

model the migration of

contaminants in both soil and

groundwater. SEVIEW seamlessly

links the SESOIL vadose zone

model to the AT123D

groundwater model. These are

the industry-standard models

used by regulatory agencies to

establish default soil leaching

standards protective of

groundwater quality.

Environmental consultants use

these models to develop higher

site-specific soil leaching

standards while maintaining

protection of groundwater.

SEVIEW was designed to be the

most powerful PFAS modeling

software ever. It goes beyond

vadose zone modeling, providing

the flexibility to simulate a wide

range of release scenarios.

Everything from PFAS released at

firefighting training facilities, to

the application of biosolids on

agricultural lands, to the

migration of groundwater

contaminants. SEVIEW unlocks

the power of the models,

enabling users to tackle

modeling projects that had

previously required using

expensive and time-consuming

numerical models.
