Product manufacturers, marketers, and clients are challenged with significant investments of time and money when developing and launching pesticidal products. Critical decisions on marketing, efficacy claims and pesticidal mode of action determine regulatory registration track, required testing programs, and the ultimate path to market. Geosyntec has broad experience in the regulation and registration of all classes of pesticide products (conventional pesticides, biopesticides, and antimicrobials) and provides science-based, business-focused support to guide clients through decision making, product positioning, and ultimately registration and market introduction. Geosyntec's Pesticide Product Services supports clients with insightful, innovative solutions. Geosyntec's team of toxicologists, risk assessors, regulatory specialists, and chemists have extensive experience and knowledge of pesticide testing, submission, and label requirements under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). We know how to position projects for efficient registration review and processing, and how to avoid misinterpreted guidance, labels, and efficacy claims that can add months to review timeframes and can significantly increase costs. We can assist with navigating all areas of FIFRA including: Preparing a product/pesticide registration strategy Meeting with and advocating on behalf of companies with regulators Developing and submitting FIFRA registration packages, renewals, and label updates Product label content development Preparing inert ingredient petitions Developing data waivers and rationales Scoping, placing, and monitoring product toxicity, physical characteristic, and efficacy studies Responding to regulator requests Pesticide device strategy, claims, data, and regulatory tracking State-level registrations Geosyntec and our wholly-owned SiREM lab manage data generation for new product registrations and amending existing products, particularly for antimicrobial products. Geosyntec and SiREM provide in-depth analytical consulting support covering toxicology studies and antimicrobial efficacy testing. SiREM provides Good Laboratory Practice (GLP) standard antimicrobial testing (i.e., bacteria and virus) to support required testing and methods under FIFRA. The Geosyntec and SiREM team allows for expert level review and strategy development of testing programs, as well as expedited access to efficacy testing, which can save months in registration timelines.

Clients are faced with chemical risks throughout their business products, facilities, and supply chains. Increased regulations at global, regional, and national levels; combined with an expanding list of chemicals of concern; requires companies to demonstrate compliance to regulators while also addressing consumer and stakeholder expectations. Geosyntec provides advisory and evaluation support for multiple aspects of chemical management, from regulatory compliance to safety and supply chain transparency. We actively support chemical safety assessments and product stewardship summaries to help chemical and product manufacturers address public health concern challenges, regulations and data gaps associated with chemicals in the marketplace. Our services include: Compliance Tracking Management: Geosyntec's compliance team supports companies across applicable regulatory phases in their use and management of chemicals and production of a range of industrial and consumer products. This requires detailed knowledge of applicable regulatory programs; the status of specific chemicals under those programs; pending revisions and updates to the programs; and recordkeeping and reporting procedures to maintain compliance. Chemical Risk Assessment: Geosyntec's support services address human health and ecological risk assessment; hazard identification and evaluation; and exposure assessment. Restricted Substances Lists and Registrations: Our experienced practitioners know regional, national and state programs such as the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH), the Toxic Substances Control Act (TSCA), the China State Administration of Work Safety (SAWS) 53, and California Proposition 65. Characterization Testing Programs: Testing programs include human health and ecological toxicity; chemical efficacy/claims verification; chemical content and physical characteristics. Supply Chain Stewardship: Geosyntec helps clients with retailer supplier portal content; registration and tracking; Environmental, Social, and Governance (ESG) reporting; chemical and product content and safety dossiers, and Safety Data Sheets .

For decades, global chemical control and downstream product regulations, bans, restrictions, and reporting obligations have proliferated, creating major challenges for multinational corporations (MNCs).

Modeling of Humus Tanks for a Sewage Treatment Facility in England

2026-04-02T16:32:49-06:00May 8th, 2016|Tags: , , , , , , |

There are a large number of legacy biological filtration plants in the UK, dating back to the 1920s and 1930s. In such plants, the influent wastewater is screened and settled in primary tanks prior to filtration in biological filter beds.  Effluent from these beds passes to humus tanks, where residual solids are allowed to settle out. Final effluent may then be polished through sand filters prior to discharge. Humus tanks are similar in design to other types of primary and secondary settlement tanks. They can be of radial flow, upward flow, or horizontal flow types. The sludge must be removed from the tanks regularly and continuously in a large works.

Storm Tank Optimization for a Sewage Pumping Station in England

2026-04-02T16:32:45-06:00May 8th, 2016|Tags: , , , , , , |

During periods of heavy rainfall, Eastney Sewage Pumping Station diverts flow to the Fort Cumberland Storm Tank.  During the first flush, the solids content of the flow is higher than normal, which overloads 6mm band screens located upstream of the storm tank. In order to help separate a greater quantity of solids from the flow and enable the screens to work as intended, it was proposed that the storm tank receives the flow and provides a residence time for solids to settle.

Optimizing Flow and Load Distribution Within a Sewage Treatment Distribution Chamber in England

2026-04-02T16:32:44-06:00May 8th, 2016|Tags: , , , , , , |

Civil engineering structures are used to distribute the flow and solid loads to multiple settling tanks or activated sludge plant (ASP) lanes at a sewage treatment works (STW). Achieving a good solids distribution requires adequate mixing to homogenise the solids, but this can be detrimental to achieving a good flow distribution, which normally requires quiescent conditions.

Analysis and Design for Final Clarifiers in England

2026-04-02T16:32:44-06:00May 8th, 2016|Tags: , , , , , , |

The Budds Farm Wastewater Treatment Works operated by Southern Water Services Ltd. treats waste water from the Portsmouth and Havant catchments. Prior to 2006, the Wastewater Treatment Works at Budds Farm had eight final clarifiers of 35m internal diameter. In order to meet the requirement of projected AMP4 flows, the existing settlement tanks were modified and two new 35m diameter clarifiers were built to operate alongside the existing eight tanks.
