This is a list of Superfund sites in Michigan designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law.The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
Soil survey products include the Web Soil Survey, [28] the NCSS Characterization Database [29] and many investigative reports and journal articles. [30] In 2015 NRCS began broad support of soil health, which incorporates less tillage and more cover crops to reduce erosion and improve the diversity of the soil. [31]
The Michigan Natural Resources Commission (NRC) is a seven-member public body whose members are appointed by the governor to a term of four years and subject to the advice and consent of the Michigan Senate. The NRC conducts monthly, public meetings in locations throughout Michigan.

This soil is a multi-layer soil composed of humus, light sand, dark sand, and yellowish sand. It is classified as a spodosol. The distinctive sand layers can ...
This nitrogen is usually in the form of nitrate. [9] The nitrate seeps through the soil and gets into the ground water through agricultural practices such as tile drainage, which eventually makes its way into the surface waters. [10] Nitrate concentration can be dangerous passed a certain level.
The area was administered by other Michigan counties before 1879 when the county government was organized. [5] [1] Due to the location in rural northern Michigan, Crawford County's greatest economic growth occurred in the 1800s when lumbering clear-cut most of the extensive forests of Norway pine, birch, maple, beech and hemlock.

Nitrate levels above 10 mg/L (10 ppm) in groundwater can cause 'blue baby syndrome' (acquired methemoglobinemia). [84] The nutrients, especially nitrates, in fertilizers can cause problems for natural habitats and for human health if they are washed off soil into watercourses or leached through soil into groundwater.
