<br /> NOTES:
<br /> 2010 MRP used for current sampling frequency column.
<br /> A: Annual sampling
<br /> M:Monthly sampling
<br /> SA: Semi-annual sampling
<br /> Q: Quarterly sampling
<br /> B: Biennial sampling(odd-numbered years).
<br /> (a)Groundwater elevation and depth to groundwater from surface will be measured at each monitoring well and accessible supply
<br /> well in this table on a quarterly basis.
<br /> (b)Nestle can sample more frequently than required. However,results from additional samples must be provided to the CVRWQCB for review.
<br /> (c)Sampling is not required. Measurement of quarterly groundwater elevations are required.
<br /> (d)Sample if it becomes operational.
<br /> (e)Sampling frequency required for private supply wells that have wellhead treatment units installed by Nestle.
<br /> (f)New wells monitored quarterly for the year after installation. After 1 year,monitoring frequency will be reevaluated.
<br /> (g)Well abandoned or detroyed;thus,monitoring is not possible. Current report requests removal from monitoring program.
<br /> (h)Sample names appear to have been transposed between M-31 C1 and M-31 C2/D for this sample date.
<br /> (i)Sample results for M-1 OA and M-1 9C1 on October 26,2009 appear to have been transposed by the laboratory.
