Beaumont Basin Watermaster Memorandum No. 15-17 Page 2 of 53
groundwater flow direction and gradient. While it is acknowledged that a
methodology is necessary for assessing losses out of the basin, any such
methodology should include the installation of features that will enable us to collect
the data necessary to confirm the loss (e.g. monitoring wells). Regardless, the
proposal to store the water without accounting for losses does not seem tenable.
Technical Memorandum - Resolution No. 2005-01 – Section 2 – Pg. 5 of 8. -
Given the location of the proposed project and assuming that a northerly
groundwater flow direction is correct, the most likely beneficiary of the recharged
supplemental water will be other wells owned by the applicant (e.g. Tukwet A). It
is not likely that the project will significantly improve the groundwater quality for
other pumpers in the basin.
Technical Memorandum - Resolution No. 2005-01 – Section 4 - Pg. 7 of 8. - It
is stated that the total dissolved solids and nitrate concentrations in the water from
Well B are below the maximum benefit objectives for the Beaumont Basin. The
laboratory reports of water quality attached to the Technical Memorandum report
a nitrate concentration of 16 milligrams per liter (mg/L). However, the laboratory
does not indicate whether the nitrate concentration is reported as nitrogen (N) or
nitrate (NO3). If the value is reported as N, then the Maximum Contaminant Level
is 10 mg/L and the water quality would not be in conformance with the maximum
benefit objectives. The applicant should provide a revised laboratory report from
the laboratory that confirms how the nitrate concentration is reported.
Laboratory Report Chain of Custody - In the chain of custody for the laboratory
report, it is indicated that radiological analyses were requested from the laboratory
but no radiological water quality is reported. The results of these tests should be
included in the laboratory report.
A representative from the Morongo Band of Mission Indians and/or their consultant will
make a formal presentation to the Watermaster. Potential impacts resulting from the
implementation of this project should be studied carefully before making a
recommendation on this issue.
