Upper reaches impacted by trash, debris, fecal coliforms, and heavy metals from recreational use. [ 187 ] [ 188 ] [ 189 ] Coyote Creek suffering from "acute and chronic toxicity" from pesticides and industrial chemicals, industrial contaminant pollution of a considerable portion of the groundwater in the San Gabriel River watershed, and ...
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.

In the case of groundwater, the main issue is contamination of drinking water, if the aquifer is abstracted for human use. Regarding soil contamination, runoff waters can have two important pathways of concern. Firstly, runoff water can extract soil contaminants and carry them in the form of water pollution to even more sensitive aquatic habitats.
Water analysis for heavy metals must consider soil particles suspended in the water sample. These suspended soil particles may contain measurable amounts of metal. Although the particles are not dissolved in the water, they may be consumed by people drinking the water. Adding acid to a water sample to prevent loss of dissolved metals onto the ...
Heavy metals, toxins, and chemicals leak from these discarded products into surrounding waterways and groundwater, poisoning the local people. [17] People who work in these dumps, local children searching for items to sell, and people living in the surrounding communities are all exposed to these deadly toxins.
