A naturally occurring compound called geosmin is produced by bacteria in soil and algae found in surface water. Extreme temperatures can kill off algae in surface water, which releases the geosmin into the water. While the taste and odor can be unpleasant, geosmin is not toxic or harmful. The water remains safe to drink. The human nose is extremely sensitive to geosmin. If you poured a teaspoon of geosmin into the equivalent of 200 Olympic-sized swimming pools, you would still be able to smell it. The general threshold for human detection is about 15 nanograms per liter (parts per trillion); however people with sensitive pallets can detect these compounds in drinking water when the concentration is as low as 5 nanograms per liter. This is why some customers notice the changes in taste and odor while others Conser vation Tip do not. Heating the water Up to 30% of water is lost to increases the volatility of evaporation when watering these compounds, which in the afternoons. explains why the smell is more easily detected when you are in the shower or when used for hot beverages.

If present, lead is introduced into your drinking water from plumbing fixtures and materials, not from the water source. Although lead was banned from use in pipe and solder in 1986, older homes may still have materials containing lead. Where does Arlington drinking water come from? Arlington purchases its water for treatment from the Tarrant Regional Water District. The water is taken from four reservoirs. Cedar Creek, Richland-Chambers and Lake Benbrook supply the John F. Kubala Water Treatment Plant. Lake Arlington supplies the Pierce-Burch Water Treatment Plant. Cryptosporidium Monitoring Information: In 2013 Tarrant Regional Water District monitored all raw water sources for Cryptosporidium and found none in the source waters servicing Arlington. Cryptosporidium is a microscopic, disease- causing parasite, housed in a hard-shelled egg-shaped oocyst. When ingested, the oocyst splits open, releasing sporozoites. These sporozoites invade the lining of the gastrointestinal tract and can cause an illness called cryptosporidiosis. Cryptosporidiosis is typically an acute short-term infection but can become severe and non-resolving in children and immuno-compromised individuals. In addition to coagulation and filtration, Arlington uses Ozone (the primary disinfectant) to further protect against Cryptosporidium.
