Filter Reports for Individual Media Filters

Information about when a surface water public water system is required to submit a Filter Profile Report, Filter Assessment Report, or Comprehensive Performance Evaluation to TCEQ.

On this page:

If an individual media filter produces water with elevated turbidity that suggests declining performance, inadequate filtration; or, if the performance cannot be determined, additional investigative steps must be taken by the public water system. These requirements do not apply to water treatment plants with an active Corrective Action Plan issued by the TCEQ. Once data is entered into the Surface Water Monthly Operating Report (SWMOR) spreadsheet, it will automatically determine if a Filter Profile Report, Filter Assessment Report, or Comprehensive Performance Evaluation is needed.

Use the information below to determine the type of investigation report to submit.

Submit a Filter Profile Report (FPR)

An FPR is required when a single filter produces water with consecutive, 15-minute turbidity readings that are 1.05 nephelometric turbidity unit (NTU) or higher.

Complete an FPR within 7 days of the exceedance:

    Submit a Filter Assessment Report (FAR)

    A FAR is required when a single filter produces water with consecutive, 15-minute turbidity readings that are 1.05 NTU or higher, three or more times during a consecutive three-month period.

    Complete a FAR within 14 days of the third exceedance:

      Submit a Comprehensive Performance Evaluation (CPE)

      A CPE is required when a single filter, or combination of filters, produces water with consecutive, 15-minute turbidity readings that are 2.05 NTU or higher, on two separate occasions during two consecutive months.

      Complete and submit a CPE form immediately:
