Northstar Environmental Remediation (Northstar) was created to provide customers with choices. Whether you are a responsible party or a consultant, you can benefit from Northstar's unique business philosophy. Our customers do not get the "one-style-fits-all" approach to remediation. Instead, Northstar uses creative problem solving to provide a strategic approach to effective site remediation. Northstar provides onsite feasibility tests and site evaluations to identify target areas for remediation, and then applies the right technology to accomplish the goal. Once equipment needs are identified, Northstar will evaluate alternatives available in the market place to assemble remediation equipment custom-made for the site. Northstar enables clients to continuously monitor, respond to, and adjust remediation strategies as the site and regulatory environment changes. These custom services are uniquely provided at standard commodity pricing. Northstar is located in Lake Forest, California. Northstar commonly services customers located throughout the western United States. Company affiliates provide Northstar with additional reach throughout the northern U.S. and Canada. The name Northstar was chosen to graphically portray our company vision to stand out from the crowd. Northstar simplifies remediation, directs resources where they will have the most impact, and highlights the enterprise with significant cost savings for our customers.
