485 Questions from the Nation Around the World with Trace Blackmore, CWT

Ten questions from water professionals around the world become a practical decision-making session with Trace Blackmore, CWT. Drawing on earlier Scaling UP! H2O conversations, Trace explains how to evaluate treatment changes, use emerging tools responsibly, begin water reuse projects, strengthen teams, and continue growing professionally.

Evaluate the Entire System

A proposed treatment change should be evaluated by more than its purchase price. When comparing chlorine dioxide with traditional chlorine, Trace recommends examining biocide consumption, chemical storage, corrosion rates, biofilm control, heat-transfer efficiency, cleaning requirements, downtime, labor, equipment life, and Legionella risk. A documented pilot on one tower can provide evidence before a facility commits to a larger investment.

Water reuse decisions require the same discipline. Before introducing treated wastewater or cooling tower blowdown into another application, characterize the water, calculate current and projected costs, identify regulatory requirements, and determine compatibility with the existing treatment program. Starting with a blended approach or limited pilot can help a team test feasibility while managing operational risk.

Use New Tools Without Surrendering Professional Judgment

For technicians exploring AI, Trace recommends beginning with approved, nonrestricted data. Service reports and controller data can help an AI platform organize information, identify subtle trends, prepare meeting summaries, and improve the wording of recommendations.

However, AI output still requires verification. Company data policies must come first, and technical recommendations should be reviewed against field experience, trusted references, and knowledgeable mentors.

Product changes also demand controlled testing. When evaluating maleic acid-based corrosion inhibitors, Trace recommends laboratory compatibility testing, careful review of the order of addition, temperature and shelf-stability checks, and a low-risk field pilot. Corrosion coupons, system cleanliness, dosing performance, and historical results can then be compared before expanding the program.

Strengthen Teams, Goals, and Professional Growth

The listener questions also address turnover, accountability, education, and industry involvement. Trace explains how behavioral assessment can support job fit and team communication, while weekly accountability, visible goals, time blocking, and lead-measure tracking can make a 12-week plan more achievable.

He also reflects on how his MBA and DBA studies have influenced his strategic thinking, data-based decisions, leadership, and approach to scalable systems. The discussion closes with the value of continuing education, professional certification, trade association membership, committee participation, and relationships that provide support when difficult field problems arise.

These answers offer practical starting points for making better technical, operational, and professional decisions—while knowing what evidence to gather before recommending change.
