Professional Consulting Services
Expert Witness
Our belief is that expert testimony must start with a clear understanding of the foundational science and be based upon well-referenced facts and case studies. With educational skills and widely recognized credibility, Horsley Consulting provides a clear and sound scientific foundation in support of water resources cases in state and federal courts.
Watershed Restoration Plans
The capability of land to support land uses within a watershed is directly related to the assimilative capacity of the receiving waters. Scott has developed innovative approaches to document the hydrologic framework of the watershed, to evaluate impacts associated with land uses, and to identify sustainable restoration techniques.
Training & Seminars
Looking to facilitate a training or educational webinar with stakeholders on your project? We can lead and facilitate one-time seminars or a series of trainings around your water resource that ensures all team members have a foundational understanding of the topics at hand.
Stormwater and Wastewater Management
Stormwater and wastewater discharges place significant stessors on hydrologic systems, drinking water supplies, wetlands, and ecosystems. These discharges commonly alter the hydrologic regime by modifying surface runoff and groundwater recharge rates. They also contribute nutrient loads that can lead to eutrophication and contaminants of emerging concern. Scott Horsley served on the Massachusetts Stormwater Advisory Committee where he assisted in the development of the state’s Stormwater Standards. He has also served on advisory committees in the development of wastewater treatment guidelines and regulations.
Hydrologic Assessments & Water Quality Impact Assessment
Groundwater is one of the more elusive aspects of water resources frequently misunderstood by design engineers and regulators. Its interaction with surface waters and wetlands can be complex. Groundwater transport times (from source to discharge area) can be decades, and in some cases centuries. Seasonal changes in evapotranspiration rates caused by clearing of forests and vegetation can result in reductions of the assimilative capacity of watersheds and drinking water supplies. Scott Horsley has developed nutrient loading models that have been integrated into state and local government regulatory programs.
