Chemical/Radionuclide Sample Submission Guide

Web Entry Reporting

This page outlines how to report routine, special, and confirmation chemical or radiological sample results. Please note there are separate guides on Disinfection By-Product samples and Shipping Blanks (trip/field blanks). This guidance is separated into three sections to match the sections in CMDP:  general Sample Information, Chem/Rad Results, and Field Results and Measurements (this section not used for Chem/Rad reporting). Additionally, this document includes the Methods Chart and examples of completed sample submissions.

This guidance page notes the state/federally required fields within each section. Submit the information as described to help ensure a successful sample submission. Do not rely on the symbols noted in the CMDP data entry screen as they do not include the state required fields.

If you have questions, please contact DEC CMDP support staff at dec.cmdpsupport@alaska.gov.

Section 1: Sample Information

• Water System ID*: Public Water System identification number (PWSID).
• NOTE: Each water system name has a unique PWSID number. If the name and number on the work order does not match what is listed in CMDP, investigate to ensure accuracy and consistency.
• Facility*: Select the appropriate water system facility from where the sample was collected.
• Sampling Point*: Select the appropriate sample point related to the facility where the sample was collected.
  • If you are unsure of the Facility ID and Sample Point ID to enter, review the How to Find PWS Facility ID/Sample Point ID information page.
• Sampling Location*: This field must describe the location where the sample was taken from (i.e., 123 Main Street, Health Clinic, Kitchen sink, etc.). Keep description succinct (numbers, letters, dash, and underscore only).
• Sample ID*: Lab sample identification number, limit to 20 characters (numbers, letters, dash, underscore are allowed). 
• Collection Date*: Date sample collected (MM/DD/YY). 
• Collection Time (24H)*: Time sample collected (HH:MM).
• Sample Received Date*: Date sample was received by lab (MM/DD/YY).
• Laboratory ID-Name*: This field will auto-populate with the appropriate lab submitting data through CMDP or select the lab name from the drop-down menu.
• Sample Type*: This field will auto-populate with the Routine sample type. From the drop-down menu, select the appropriate sample type (i.e., routine, confirmation, special, etc.). 
  
• Repeat Location: Do NOT report a repeat location.
• Related Original Sample Collected**: If submitting a confirmation sample, relate the original lab sample ID that prompted the confirmation sample to be collected.
• Sample Volume (ML): Not Required (numerical value only).
• Sample Collector Name: Name of sample collector, report if information is provided.
• Comment**: Must include water idle time when reporting Lead/Copper samples (e.g., Idle time 7 hours 40 minutes or Water sat unused for 9 hours). Please limit characters to numbers, letters, dash or underscore. In particular, do NOT include quotation marks.

Section 2: Chem/Rad Results 

Typically, labs will only use web entry for Chem/Rads samples if it's an individual contaminant like Nitrate. If your lab reports larger groups of contaminants like IOCs, VOCs, or SOCs, the Excel template (or other method of generating XML) is utilized.

• Analyte*: From the drop-down menu, select the sample analyte(s) you wish to input data for as appropriate. TIP FOR USERS: Use the search window to filter the Analyte list by either searching for the name of the analyte or the analyte code.
• Not Detected*: This field automatically defaults to a result of a non-detect (box will be checked) when entering a new sample result. If the contaminant is detected in the sample (level above detection limit) you will need to uncheck this box.
  • NOTE: When the user clicks off of the individual sample result row, Not Detected values will be listed as true and Detected values will be listed as false.
• Result**: Enter the appropriate reported result of the sample only if reporting a detect.
• Result UOM**: From the drop-down menu, select the unit of measure for the sample result as appropriate.
• Standard Deviation (+/-): Not required but report if applicable.
• Reporting Limit**: Enter the appropriate reporting limit of the analytes.
• Reporting Limit UOM**: From the drop-down menu, select the unit of measure for the reporting limit as appropriate.
• Volume Assayed: Not required but report if applicable (numerical value only). 
• Method*: This drop-down list includes methods for ALL chemical analyses and is not filtered by the analytes your lab (or subcontracting lab) is certified for. Be sure to verify certification status and select the appropriate method. If the method is reported incorrectly, it will be rejected from the state database. If you are unsure which method should be reported, please see the Methods Chart to determine correct reporting.
• Analysis Start Date*: Date when lab began analysis (MM/DD/YY).
• Analysis Start Time*: Time when lab began analysis (HH:MM).
• Analysis Completed Date: Not required but report if information is available (MM/DD/YY).
• Analysis Completed Time: Not required but report if information is available (HH:MM).
• Analyzing Lab ID**: If the sample was subcontracted to a different lab for analysis, the analyzing lab identification number is required to be reported here.
• Person Preforming Analysis: Not required.
• Comment: Not required, however if comments are provided, please limit characters to numbers, letters, dash or underscore. In particular, do NOT include quotation marks

Section 3: Field Results and Measurements

REMINDER! This section should NOT be used for Chemical/Radionuclide sample submittals. Please leave fields blank.
