Budget estimate

$900,000 – $2,000,000

No total contract ceiling is disclosed; however, the addendum lists estimated quantities of ~1,011 colilert tests, 323 Quanti‑Tray tests, plus dozens of chemical analyses. Assuming average unit prices ranging from $150 (colilert) to $300 (chemical analyses), the annual spend could be roughly $300,000‑$500,000, leading to a three‑year contract value between $900,000 and $1,500,000. Adjustments for travel, supplies, and overhead could push the high end toward $2 million.
