  • Site Investigation, Sampling & Waste Profiling
  • Material Profiling & Manifest Preparation
  • Excavation, Transportation & Disposal
  • Dewatering
  • GIS Services & 3-D Monitoring

What sets Summit apart from the competition is our ability to cover the entire removal process. From initial plan preparation and sampling to transportation and disposal of hazardous materials, Summit has the knowledge required to complete the project from start to finish efficiently and on time.

More than half the bridges in California are rated to be in “Fair or Poor Condition”. These ratings are based on a few variables such as cracks, concrete loss and the need to repaint. That is not up to our standard at Summit. Modernizing bridges is essential to our Nation to keep our economy and supply chains running smoothly and for our day to day activities.

With a record backlog of projects, Summit is rebuilding California and improving bridge and community safety one project at a time. You can read the full article HERE and also view some of our past bridge and bikeways projects HERE.


Employee of the Month – Rachel Banach! During her time at Summit, she has increased both our client base and revenues. Her experience in estimating has fine-tuned Summit’s bidding process to allow Summit to bid on more projects, which has resulted in a record of backlog work.

This Past Month at Summit


Featured Project!


During the month of April we broke ground on the District 7 Trancas Creek Bridge Project in Malibu, California awarded by Stacy and Witbeck Inc. This project includes:

  • Removing and disposing of 1,500 tons of ADL
  • Sampling and Analysis for lagoon water
  • Air monitoring and ADL training
  • Engineering support and site management

This is in preparation of a new and improved bridge that will increase safety and efficiency for the community. The source of the contaminated soil was from the use of leaded fuel. By removing this hazardous material, Summit is preventing:

  • Toxic waste from migrating into the groundwater and beaches
  • Eliminating carbon emissions
  • Protecting construction workers from health hazards
  • Creating a healthier community for families

This project is a step closer towards our goal of protecting both the environment and our communities by providing sustainable green methods towards the modernization of the transportation in California. To watch the removal process live, please check out our drone footage HERE!

Summit Environmental Contractors to schedule to start work from Christensen Brothers General Engineering for the Sewer Replacement & Pavement Rehabilitation Improvement Project for the city of El Monte, California. Summit will be providing:

  • Removal, Transportation and Disposal of Hazardous Materials
  • Field Screening & Testing of Contaminated Soils
  • Dewatering and Training of Construction Personnel
  • Air Monitoring & Health and Safety Plans

By removing this material it prevents the toxins from migrating into the groundwater supply, restores contaminated waterways, and creates more reliable water systems with lower environmental impacts for a greener and sustainable future. This scope of work is in preparation of improving the current wastewater infrastructure for the surrounding community and by doing so, creates new innovative solutions for a more efficient waste management system.

Summit Environmental Contractors is at the forefront of removing contaminated materials and is a trusted source for Federal, State and private sector projects. It is more than being environmentally responsible; our purpose is to provide environmental solutions for infrastructure projects

Removing ADL for Malibu, California Trancas Creek Bridge Replacement Project 

Most of the population has heard of the negative effects that lead can have, but most do not know that the use of lead in engines produces harmful exhaust fumes that coat our roadways, our drinking supply and negatively impacts our air quality.  If not addressed now, these hazards will continue to serve as a major factor in environmental pollution and poor health in our communities.  


Starting in the 1920s, inventors thought they had found the solution to every mechanical issue within the transportation community by adding lead into gasoline with the slogan to knock out the knocks in engines. This continued into the 1970s when finally, the EPA started to phase it out due to the catastrophic health and environmental impacts lead emissions were having on the community.  


Unfortunately, this discovery came many years too late as scientists conclude that lead emissions “exposure accounted for 900,000 deaths and 21.7 million years of healthy life lost (disability-adjusted life years, or DALYs) worldwide due to long-term effects on health in 2019” (WHO,2021) and warn that “if not detected early, children with high levels of lead in their bodies can suffer from damage to the brain and nervous system, behavior and learning problems (such as hyperactivity), slowed growth, hearing problems, and headaches(DTSC, 2016).


Scientists warn the public that “lead is a serious contributor to environmental pollution that accounts for a quarter of the global burden of disease”(UNEP, 2022) and while the ban on leaded fuel has long passed, it is still being used in aviation travel and further EPA studies show that “360,000 children under the age of 5 live near at least one of the airports where piston-engine aircraft operate. Multiple additional studies have shown that children living near such airports have higher levels of lead in their blood”(Wittenberg,2022).   


As part of Summit’s ongoing efforts to support the modernization of the nation’s transportation system, we have removed 50,000 tons of ADL in the past 3 years. Together we can utilize the one trillion-dollar infrastructure bill to maximize the opportunity to provide a safer community and ensure a cleaner environment for our children. 


This is our call-to-action CEO and Founder Dave Aronne at Summit Environmental Contractors (SEC) says.  He explains that “SEC is hard at work eliminating the source of lead contamination from our nation’s transportation system. To accomplish this goal, we need your help”. 


Summit hard at work removing 1,500 tons of contaminated soil from Malibu, California to protect our beaches and the public from toxic materials. By removing this toxic material, contractors can safely expand the bridge and reduce the hazards of ADL from our environment. This is the start of a healthier future!


Summit Environmental Contractors was founded with the goal of providing environmental-based solutions for all aspects of construction infrastructure projects. Using advanced modeling and statistical technology, we quantify environmental issues in advance of construction!

Environmental pollution can be detrimental to infrastructure modernization and may cause project delays and health hazards. We believe the nation’s current infrastructure is outdated.

It needs to be modernized to provide for a more sustainable and healthier environment for the future.

With such a strong leadership team, there is no doubt that this company will become a leader in its field in coming years. We want you to meet our amazing line up that is making environmental-based solutions a reality everywhere!
