<br />Acronyms and Abbreviations:
<br />CWLAM = cannery waste land application
<br />GW = groundwater
<br /> L = leachate

<br />USEPA = United States Environmental Protection Agency
<br />1. Constituent of concern 5-year parameters. Testing was completed during the second quarter of 2023 monitoring period instead of the first quarter. Therefore, the
<br />next 5-year testing will be completed during the third quarter 2028 monitoring period, with testing to continue alternating between the first and third quarters every 5
<br />years.
