Shreveport Water Department addresses taste, odor in water
SHREVEPORT, La. (KTAL/KMSS) — The City of Shreveport's Water and Sewerage Department is addressing temporary changes in the taste and smell of the city's drinking water.
According to a press release from the city, officials say these changes, caused by naturally occurring algae blooms in Cross Lake, have led to the presence of Geosmin, a harmless compound responsible for an earthy taste and odor. The department reassures residents that despite the noticeable changes, the water remains completely safe to drink and use for household purposes.
'Geosmin is not harmful to health, but we understand it can be unpleasant,' said William Daniel, Director of Water and Sewerage. 'We are actively working to resolve this issue and appreciate the community's patience.'

The city typically treats Cross Lake with copper sulfate from March to November to manage algae growth. The most recent treatment, conducted in late November, exhausted the 2024 inventory.
Officials say that the unseasonably warmer water in Cross Lake led to additional algae growth in December and January. Although the City has placed an order for additional copper sulfate delivery has been delayed due to last week's snow in south Louisiana. Suppliers are working to expedite the shipment, which is expected to arrive soon.
The water treatment plant is continuing oxidation with ozone to address the odor. While ozone is highly effective against Geosmin, intermittent outages occurred during recent cold spells. The city says these outages, lasting only a few hours at a time, contributed to the odor being more noticeable for some residents. The issues with the ozone generator have been resolved and the generator is back in service. Other treatment processes used at the plant, including chlorine dioxide, coagulation, and chloramination, are not effective against Geosmin.
'We are committed to providing our residents with safe, high-quality water and are taking every measure to address the current situation,' added Daniel.
Officials say residents can expect noticeable improvements in taste and smell over the next two weeks as copper sulfate treatments resume and ozone operations continue.

Wx Worries: Timing of strongest storms this weekend
SHREVEPORT, La. (KTAL/KMSS) – Thunderstorms will return to the ArkLaTex this weekend. Futurecast indicates two main waves of storms. One on Saturday night & Sunday morning, and a second Sunday night into Monday. Sunday night's storms could be the strongest. After a dry day over most of the ArkLatex on Saturday. Scattered storms will move across mainly the northeast half of the area Saturday night. While SPC indicates that we have a slight severe weather risk, hi-res models indicate that we could see the storms remain slightly below severe limits with wind gusts of 30 to 50 mph. Some hail will also be possible. Tornadoes are looking doubtful Saturday night. These storms will likely weaken as they move across NW Louisiana late Saturday night into Sunday morning. Several hi-res models are indicating that we will see a complex of storms develop over NW Texas Saturday afternoon. These storms will likely move into the ArkLaTex sometime late Sunday night. Futurecast indicates that this wave of storms could be stronger and could bring a damaging wind threat as they move across mainly E & NE Texas and NW Louisiana late Sunday night into Monday morning. SPC again has our area's severe storm risk at level 2 or slight. That means any severe weather issues should be somewhat scattered. Based on current information, I'd put my level of worry for Saturday night's storms at 3 out of 10 and 4 out of 10 for the possibly stronger storms late Sunday night into Monday. The threat of scattered storms will likely continue through at least next Friday. The latest run of the Blend of Models shows a big variation in rainfall potential with amounts ranging from around 1.5' over the southern part of the area to over 5' over the NW part of the ArkLaTex. Any Tropical worries? The National Hurricane Center indicates that we will likely not see any tropical development in the Atlantic Basin during the next week. Long-range models show that the tropics could stay quiet for the next two weeks. You might notice a bit of a haze in the air this weekend as some dust from the Saharan Desert moves over the 2025 Nexstar Media, Inc. All rights reserved.

SHREVEPORT, La. (KTAL/KMSS) – The weather this weekend across the ArkLaTex will begin with mainly dry weather on Saturday with some of the hottest temperatures of the year so far. Thunderstorms will increase over the area with a few waves Saturday and Sunday nights. Hot and Humid Saturday: While a few showers will be possible over the northern edge of the area on Saturday, most of the area will see plenty of sunshine with plenty of heat and humidity. Lows Saturday morning will begin in the low to middle 70s. Daytime highs will likely soar into the upper 80s to lower 90s over the northern edge of the area to the middle 90s over East Texas and Northwest Louisiana. Storms likely Saturday night & Sunday: Futurecast continues to show more thunderstorms developing to the northwest of the ArkLaTex late Saturday afternoon and evening. These storms will move into and through the area Saturday night and Sunday. Another, and possibly the strongest wave of storms, will move across the area on Sunday night and Monday morning. Our primary threat will be damaging winds and possibly some hail. An isolated tornado can't be ruled out. The Storm Prediction Center indicates that we will have a level 1 to level 2 severe weather risk Saturday night. That risk will be highest over the northern half of the area. They also indicate that the marginal to slight risk will continue on Sunday and will once again be highest over the northern half of the area. More storms next week: We will continue to see occasional waves of scattered storms in the ArkLaTex through ALL of next week. Given how warm and humid it will be, more severe weather will be possible. The Blend of Models now shows that 10-day rainfall potential in our area will be in the range of two to potentially over five inches. Overnight lows next week will remain above normal in the low to middle 70s. Daytime highs will be near normal and mainly in the 80s and low 90s.
