About this file
This document appears to be a set of water quality testing requirements, modified from the Washington Administrative Code, that specify the Maximum Contaminant Limits (MCLs) for various inorganic chemicals and physical characteristics. It includes a table of primary and secondary MCLs for substances such as antimony, arsenic, barium, fluoride, nitrate, and turbidity, among others.
The document is related to a federal contract opportunity from the Department of Health and Human Services Indian Health Service for the installation of a residential drinking water well. The contractor will be responsible for drilling the well, including casing, liner, screen, development, and water sampling. The estimated well depth is 250 feet, and the contractor must obtain any necessary permits.

Chemicals required to be tested and corresponding Maximum Contaminant Limits (MCLs), modified from the Washington Administrative Code (WAC) Section 246-291-171. Note: A bacterial test is also required.
Table 1
INORGANIC CHEMICAL CHARACTERISTICS
Substance Primary MCLs (mg/L)
Antimony 0.006 Arsenic 0.01 Barium 2.0 Beryllium 0.004 Cadmium 0.005 Chromium 0.1 Cyanide 0.2 Fluoride 4.0 Mercury 0.002 Nickel 0.1 Nitrate (as N) 10.0 Nitrite (as N) 1.0 Selenium (Se) 0.05 Sodium (Na) * Thallium 0.002
Substance Secondary MCLs (mg/L)
250.0
2.0 0.3
0.05 0.1 250.0
Chloride (Cl) Copper (Cu)** Fluoride (F) Iron (Fe) Lead (Pb)** Manganese (Mn) Silver (Ag) Sulfate (SO4) Zinc (Zn) 5.0
*Although there is not an established MCL for sodium, there is enough public health significance connected with sodium levels to require inclusion in inorganic chemical and physical monitoring.
**MCLG (Maximum Contaminant Level Goal), as set by the Washington State Department of Health Lead and Copper Rule.
