This is a Laboratory Chain of Custody Log template document associated with the Gibson Ranch Park Water Well Monitoring contract opportunity in California, administered by the Department of Regional Parks and the Sacramento County Environmental Management Department. The template is designed to document the collection, handling, and transfer of water samples for laboratory analysis. It accommodates up to ten sample entries per page and includes fields for recording sample identification, sampling dates and times, container quantities, matrix types (including drinking water, groundwater, wastewater, seawater, soil, sludge, air, and wipes), preservative codes, and specific analysis requests. The form captures chain of custody information including sampler signatures, dates, times, and personnel responsible for receiving and relinquishing samples, along with project details, contact information, work order numbers, quote numbers, and delivery format preferences.

The template provides standardized fields for laboratory processing options including turn-around time selections (standard, one-day rush, two-day rush, or three-day rush), analytical flags, detection summary reports, and various output formats such as PDF, GeoTracker, EDD, CLIP EDT, and dry weight calculations. The form includes extensive checkbox options for documenting analysis requests and special instructions, with designated spaces for comments and field observations. This document serves as a critical compliance tool for the water system monitoring contract, ensuring proper documentation of sample integrity and regulatory adherence required by Sacramento County Environmental Management Department for the drinking water quality monitoring and system compliance activities at Gibson Ranch Park's two wells serving over 1,000 persons.
