Water Quality Monitoring Program - Summit Lake Watershed

Client: Summit Lake Paiute Tribe

Location: Summit Lake, Nevada

Period of Performance: June 2003 - 2006

Goals: Begin to establish viable and pertinent water quality standards under Section 106 of the Clean Water Act in order to protect human health and the environment. The closed Summit Lake system constitutes the primary source of drinking water on Tribal lands, and encompasses ecological considerations in regard to protection of the Lahonton cutthroat trout, a federally listed threatened species.

ADH Responsibilities:

• Perform Semi-Annual Sampling at Fourteen Sites Within the Summit Lake Watershed
• Prepare all Respective Water Quality Monitoring Reports
• Prepare Field Sampling Training Manual
• Provide Ongoing Program Consultation
• EPA Liaison
• Participate in Tribal Council Meetings Including Preparation of Presentation Materials
• Train Tribal Members on Proper Water Quality Sampling and Monitoring, and Documentation Procedures

Water Quality Monitoring: Sampling is performed in the spring and fall to take advantage of thermal homogeneity of Summit Lake and to reflect overall water quality during seasonally high and low water levels. Sample sites include 7 lake, 5 creek, 1 well and a spring. Water quality is tested, sampled and analyzed for general physical parameters, nutrients, bacteriology, organic, and inorganic analyses

Reporting: Prepared technical reports for each of four Water Quality Monitoring events (Fall 2003, Spring 2004, Spring 2005, and Fall 2005). The reports include the following: Executive summary; Project description and objectives; Discussion of the methods employed to execute the field investigation; Results of field activities performed; and, Quality Assurance/Quality Control (QA/QC) evaluation to assess the validity of the data collected including a review of the field sampling log forms and analytical laboratory results.

Client Training: A training manual was prepared as a guidance document to assist in the training of Tribal members in the project- and site-specific applications of monitoring and sampling procedures. Client training was performed during each sampling event.
