Maps
The two maps included, although related to water pollution, do not seem to make any point related to the basic article and seem superfluous.

- Agreed, removed to here with nowiki tags. If they are to be used, should be in context and reduced in size or thumbed.

Drinking Water Equivalent Level
The Drinking Water Equivalent Level (DWEL) is a measurement based on health risks used in developing limits for specific contaminants. An article on that may be more appropropriate place for discussion and elaboration.
According to the USEPA web site, the units for DWEL are milligrams per Liter (mg/L) not milligrams per milliliter.
The entry was as follows: "The Drinking Water Equivalent Level (DWEL) is the concentration (in mg/mL) of a chemical contaminant in water that is deemed safe (in other words, the risk of poisoning is 10−6)."
I am deleting this from the basic Water Pollution article rather than trying to clarify and correct the entry. Perhaps someone can do an aricle on Health-based contaminant limits and an entry on DWEL specifically that can be linked to.
