Assistance Type: OTHER REGULATORY - Discussed COE soil sampling results
Reasons: IOCs
Details: Mr. Benthin asked whether DWS may require anything at the City of Gates in response to recent tests conducted by the COE that found arsenic and antimony in soil or sediment at Big Cliff Reservoir. I checked recent inorganic monitoring results and said I don't believe DWS would require any action in a case like this when the chemicals are suspected to have been at the site for more than 60 years. We discussed that it may be helpful to have information ready in case the tests are published and customers are interested and even an additional round of samples could help to allay customer concerns.
