| Details: | SUMMARY: Recommendations for water heaters with hydrogen sulfide DETAILS: Circuit rider was contacted by Watseco-Barview Water District to provide assistance with elimination or reduction of sulfur smell in drinking water. The water district (located just south of Rockaway Beach) provides water to approximately 190 services. The water source is a groundwater well. The operator treats the water with permanganate and sodium hypochlorite to reduce sulfur odor. Upon visiting the district, it was revealed that the hydrogen sulfide odor was not present immediately after the treatment plant, but develops in dead-end water mains. As the water system was previously unfiltered, it was determined that there are likely H2S-producing bacteria present in sediment at the bottom of some pipes. ACTION NEEDED: Provided written recommendations for hot water heater cores which will result in less reaction with the hydrogen sulfide. | ||
