Raw, untreated groundwater from a test well being considered as a potential drinking water source for C.C. shows radioactive contamination and arsenic levels that exceed federal safety standards.

Groundwater monitoring beginning in 2019 at the site’s coal ash ponds found high levels of arsenic, lithium and molybdenum at levels that require corrective actions. The pollutants must be cleaned up, but the report by Ohio-based firm Haley Aldrich says they pose “no adverse impacts on human health or the environment.”

For decades, Gary residents filled jugs and bottles at the artesian well on Chase Street, a place many affectionately called the source of “magic water.” But now, the spout is dry. The water is shut off,

Arsenic leaking from abandoned gold mines can harm forest ecosystems by entering soils and affecting soil organisms. In a recent study, researchers tested forest soils with different chemical properties to see how they influence arsenic mobility and toxicity in springtails.

Arsenic is a naturally occurring element found in both soil and groundwater. Rice plants have a unique ability to absorb arsenic from the soil, especially when grown in flooded fields—a common practice in traditional rice farming. The biggest concern is ...

According to EWG data, 29 states have one or more water utilities with levels of arsenic higher than the EPA's legal level.
