0 TREND ANALYSIS <br />For well -analyte pairs that exceeded the respective TL, a temporal trend analysis was <br />conducted to assess if statistically significant increasing or decreasing temporal trends present <br />in the data. Mann-Kendall/Sen's Slope trend analyses were performed by GLA using Sanitas <br />statistical software, and water quality data collected for the eight most recent sampling events <br />to evaluate for the presence of significant statistically increasing trends. Trend analyses <br />calculations are attached. <br />NON -STATISTICAL DATA ANALYSIS <br />For those substances that have no natural background such as VOCs, pesticides, and other <br />anthropogenic compounds, GLA performed the non -statistical "VOC Special" data analysis <br />required by Resolution No. 93-62 of the State Water Resources Control Board, titled "Policy for <br />Regulation of Discharges of Municipal Solid Waste" for VOCs detected less than 10 percent of <br />the time in background samples. Under the VOC Special analysis, a measurably significant <br />indication of release occurs in a given sample when: two or more VOCs exceed their respective <br />Method Detection Limits (MDLs); or one or more VOCs equals or exceeds its respective <br />practical quantitation limit (PQL). <br />
