Environmental Data Services

Linda L. Tangen environmental data services was started in 2002 to meet the needs of consulting firms, government entities, and industries with their environmental data management and quality assessment.  As an environmental consultant (scientist) with laboratory management and environmental data validation experience, forming a company seemed an obvious way to to meet these needs and showcase my talents.  In addition, with low overhead costs, I was able to pass the cost savings along to my clients with low rates...A must with today's world of budget constraints.  

After many years of developing good working relationships with project managers, my services have expanded to include environmental database management with secure off-site storage, statistical data review, help with field and laboratory data collection project work plans and the delivery of environmental data in custom formats.  Staying "up to date" with environmental validation procedures (i.e. EPA, state and site-specific work plan requirements) and database functions are crucial to my business.  Working diligently with project managers to achieve their goal of collecting usable data, is a main priority.
