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 />
