Navigating the Monitoring Summary

To understand the 4 sections of information presented within a monitoring summary, either review the information presented below or view the How to Read the Monitoring Summary (Length: 21 min).

Section 1: Monitoring Summary Information

Section 1 is separated into two distinct areas, A and B. Part A includes general information about the water system.

1. Water System Name
2. Public Water System Identification Number (PWSID)
3. Total Population Served
4. Date Monitoring Summary was created and saved to Drinking Water Watch
5. Federal Water System Type and Source Water Type

Part B includes general information about Sanitary Survey and sampling requirements.

6. Requirement: This column lists the specific contaminant or contaminant group the pWS needs to test. The Sanitary Survey requirement will alos be noted in this column.
7. Sample Point ID: This column lists the sample point identification code associated with the sample location.
8. Required Sampling Frequency: This column notes the number of samples and how often the sample(s) need to be collected.
9. Last Sample: This column lists the last sample date for the contaminant the Drinking Water Program has on record.
10. Next Sample: This column notes when the next sample for the contaminant is due.

The Monitoring Summary displays the water system facility (or sample location) where each sample is required to be collected. For example, samples listed under the Facility ID DS (distribution) must be collected in the distribution system while samples listed under the Facility ID TP (treatment plant) need to be collected at the entry point to the distribution. The Sample Point ID associates a specific sampling point with the sample location. The Facility ID and Sample Point ID are required information for submitting laboratory sample results to the State.

  • Facility ID: This identification code is associated with the facility where the sample should be collected.
  • Sample Point ID: This column lists the sample point identification code associated with the sample location.

The table below highlights the types of water system facilities and the two-letter code (such as TP and DS).

*NOTE: Samples collected at a well could be source/raw water sampling or represent the entry point to the distribution system. If you are unsure about the samples for your system, consult your EPS.

Section 2: Stage 2 Sampling Detail

For systems subject to Stage 2 D/DBPR requirements, this section describes sampling for this rule. Sampling must occur at the specific location(*) and time of year indicated in the Compliance Monitoring Plan. Samples submitted from the incorrect locations or outside of the designated timeframe will not be accepted by the Drinking Water Program.

*Depending on the system's sampling requirements, DBP2 will be listed as a dual sample set (i.e., TTHM & HAA5) or as individual samples (i.e., individual TTHM sample and individual HAA5 sample).

1. Contaminant: This section indicates which Stage 2 contaminant the sample should be analyzed for at the laboratory.
2. Sample Pt. ID: This column lists the sample point identification code associated with the sample location.
3. Location: This section represents the location in the water system where the sample should be collected.
4. Sample Count: This section specifies how many samples should be submitted for analysis.
5. Sample Dates: This area designates the month(s) a Stage 2 sample is required.

In order to understand Stage 2 sampling requirements, review the number and frequency of samples required (located within Section 1, noted by A in the screen shots below) and information on the specific location and month(s) samples need to be collected (located in Section 2, noted by the B in the screen shots below):

Example 1: Dual Sample Set

Example 2: Individual Sample Set

Section 3: Operator Report

This section outlines the requirements for the Monthly Operator Report

1. Requirement: This column lists the specific contaminant or contaminant group the PWS needs to test.
2. Location: This column lists the location where the samples/measurements should be taken.
3. Sampling Frequency: This column notes the number of samples and how often the samples/measurements need to be collected.
4. Last Report: This column indicates when the last operator report was submitted to the Drinking Water Program

Section 4: Compliance Schedules

Compliance Schedules track other (non-sampling) requirements such as the Consumer Confidence Report (CCR) or additional follow-up activities for Sanitary Survey deficiencies.

1. Compliance Schedule Type: This field identifies what issue the compliance schedule is addressing. This example details a Consumer Confidence Report Schedule.
2. Activity Type: This field lists what specific action needs to be taken.
3. Due: This column lists when activities need to be completed.
4. Comments: The comments are written by the EPS assigned to the PWS to provide additional details to the schedule requirements

Notes and Contact Information

The last section on the Monitoring Summary lists additional notes pertinent to sampling timeframes as well as the contact information for the EPS assigned to the public water system.

NOTE: Review the flyer or email sent by your EPS as it will contain important information and additional reminders for the upcoming year.
