While a fire continues to burn on the T'suu T'ina reserve, great strides has been made on the blaze, forcing it down to the point where an advisory could be lifted soon.

An air quality advisory remains in effect in the south part of the city on Thursday, but with backhoes turning over smoldering material in the gravel pit and crews pouring water in to put out the fire, the smoke has been significantly reduced.

CTV has spoken with residents in the affected areas and they say that the air is quite good now and, as a result, all signs point to the air advisory being lifted in the next few hours.

Currently, what's left of the smoke is drifting west over the reserve and towards Bragg Creek.

The blaze started at just after midnight on Wednesday in a gravel pit filled with organic material.

The southern part of the city had the worst of the smoke, including Woodbine, Somerset, Evergreen, and Bridlewood.

AHS says minor smoke conditions do not typically cause health concerns in most healthy individuals but if smoke conditions get worse, even healthy individuals may experience irritation of eyes, throat and possibly shortness of breath.

Health officials say all residents and visitors to the area should monitor their own health and adapt their activities as necessary.

People with respiratory conditions such as COPD and asthma, and individuals with existing cardiovascular conditions such as angina, previous heart attack and congestive heart failure, may be more likely to notice a worsening of their symptoms.

AHS is advising these individuals to take precautions recommended by their physicians if symptoms become more severe.

Individuals experiencing symptoms can also call Health Link Alberta 24 hours a day, seven days a week, toll-free at 403.943.LINK (5465), to speak to a registered nurse.
