LADS interpretation
What the evidence means—and does not mean
- These measurements belong to PWS TX0790003, not every Rosenberg mailing address.
- The report describes both groundwater and purchased surface water, so source conditions can vary within the system.
- Regulatory results are system context; test the untreated tap when equipment sizing depends on current property conditions.
