Therefore, upon initial contact, Erthwrks plans a source-specific testing schedule, with deadlines, to plan an effective compliance schedule. In addition, Erthwrk’s project managers participate in continuing education programs with various environmental consulting companies and pass on this knowledge, helping our clients keep up with the constantly evolving regulations. Erthwrks also provides our clients with a list of proactive maintenance and key performance indicators (KPIs), based on our subject matter expertise and years of experience testing similar sources, to ensure ongoing compliance for each source.
