Two locations at the stormwater detention pond (two sampling locations total ) : <br /> Stormwater Treatment Lake Inlet <br /> Stormwater Treatment Lake Outlet <br /> Number of Surface Water Sampling Events : <br /> Stormwater Treatment Lake Inlet — 7 storm events <br /> Stormwater Treatment Lake Outlet — 7 storm events <br /> Total Number of Samplings : <br /> Surface Water — 14 flow-weighted composite samples ( 7 from each sampling <br /> location ) <br /> Rainfall Events : <br /> The compositqUsamplers ' float switches will be set so that they are not activated <br /> until the lake surface rises approximately 1 inch . This will insure that a significant <br /> rainfall event is being sampled . <br /> Rain Gauge : <br /> A rain gauge will be located within the fenced stormwater treatment pond area at <br /> each stormwater treatment lake site . Rainfall readings will be recorded to the <br /> nearest 0 . 01 - inch , each work day throughout the entire water quality monitoring <br /> program . <br /> Surface Water Testing Parameters : <br /> Field Measurements : <br /> 1 , Specific Conductance <br /> 2 . pH <br /> Laboratory Analyses : <br /> 1 . Total Kjeldahl Nitrogen <br /> 2 , Nitrate - N , Nitrite = N <br /> 3 , Ammonia - N <br /> 2 <br /> F:\Public Works\KeithM\Stormwater Projects\Roseland\QAPP - Quality Assurance Project Plan\East Roseland <br /> Stormwater Sampling Plan - Revised July 23, 2004. doc <br />
