Mold Testing and Remediation Overview: Following IICRC S520 Standards

The IICRC S520 standard provides a clear guide for safely managing mold issues in homes and buildings. Its main goals are to protect people, ensure thorough cleanup, and prevent future mold problems.

1. Assessment and Inspection

Initial Assessment:

  • Trained professionals will conduct a detailed inspection of the affected area. This includes visual checks and using tools like moisture meters and infrared cameras to find hidden mold or moisture.
  • Understanding moisture sources is crucial, as mold often arises from water issues or high humidity.

Mold Sampling:

  • Although not always needed, testing (both air and surface samples) can help identify the type and amount of mold present.
  • Sampling is useful when mold is suspected but not visible, such as when there are odors or health concerns.
  • If sampling is done, it must follow proper protocols, with analysis performed by accredited labs.

2. Containment Protocols

Containment Procedures:

  • To stop mold spores from spreading during cleanup, barriers (like plastic sheeting and negative air pressure) are used.
  • The extent of containment varies; small areas might require basic barriers, while larger or heavily contaminated spaces need more extensive containment.
  • Workers must enter and exit through decontamination chambers to avoid spreading mold.

3. Personal Protective Equipment (PPE)

  • Workers should wear appropriate PPE, including gloves, N95 masks, full-body suits, and eye protection.
  • The type of PPE needed depends on how severe the contamination is; more protective gear may be required for heavily affected areas.

4. Remediation Process

Source Control:

  • Addressing the root cause of moisture is essential. This may involve fixing leaks, improving ventilation, or managing humidity.

Cleaning and Removal of Mold:

  • Mold cannot just be treated with chemicals; it must be physically removed.
  • Non-porous materials (like metals and glass) can often be cleaned with HEPA vacuums or damp cloths.
  • Severely affected porous materials (like drywall and carpets) should be removed and disposed of according to local regulations.
  • HEPA air filtration systems should be used to capture airborne mold spores during cleanup.

Cleaning Techniques:

  • Common methods include HEPA vacuuming and scrubbing surfaces where mold is present.
  • Antimicrobial agents may be used, but the focus is on physical removal.

5. Post-Remediation Evaluation

Final Inspection:

  • After cleanup, a visual inspection ensures no visible mold remains.
  • Air and surface tests may be conducted to confirm that mold levels are back to normal.
  • It's crucial to check that the environment is dry to prevent mold from returning.

Documentation and Reporting:

  • Detailed records of the remediation process, including testing results and cleanup procedures, should be maintained.
  • This documentation is important for compliance and may be needed for insurance or legal matters.

6. Ongoing Prevention

  • Educating building occupants about moisture control is vital. This includes maintaining HVAC systems, managing humidity, and promptly addressing leaks.

By adhering to the IICRC S520 standard, mold remediation professionals take a systematic and health-focused approach, ensuring that indoor spaces are restored to safe, mold-free conditions.

Engaging a mold remediation expert ensures that the mold is not only removed but that the air quality in your home is restored to a safe level, protecting the health of your family.

Preventing Future Mold Growth

After remediation, it's essential to take proactive steps to prevent mold from returning.

Disaster Response's trained technicians are equipped to handle even the most challenging mold situations, ensuring that your home is restored to a safe and healthy state.

Reach Out to a Mold Remediation Specialist in Sioux Falls, SD, for These Mold-Related Issues

Mold growth can occur in various environments, particularly in areas with high humidity or water damage. This fungal growth can lead to significant health risks, property damage, and unpleasant odors. Recent studies have shown an increase in mold-related issues in Sioux Falls, with many homeowners facing challenges in managing and eliminating mold effectively. If you find yourself dealing with any of the following mold situations, it's crucial to contact a mold remediation expert promptly:

Visible Mold Growth

If you notice mold on walls, ceilings, or other surfaces, it's a clear sign that professional intervention is needed. Mold can spread quickly and may indicate underlying moisture problems.

Musty Odors

A persistent musty smell in your home can be a strong indicator of hidden mold. This odor often suggests that mold is present, even if it's not immediately visible.

Water Damage

Following a leak, flood, or any water intrusion, the risk of mold growth increases significantly. It's essential to address any water damage promptly to prevent mold from taking hold.

Health Symptoms

If you or your family members are experiencing unexplained respiratory issues, allergies, or skin irritations, mold exposure could be the culprit. Seeking professional help can ensure a safe living environment.

Condensation Issues

Excessive condensation on windows, walls, or pipes can create a breeding ground for mold. Addressing these issues with a mold remediation service can help prevent future growth.

Previous Mold Problems

If you've dealt with mold in the past, it's vital to monitor the area for any signs of recurrence. A professional can assess the situation and implement preventive measures.

Regardless of the mold issue you're facing, it's important to understand that Sioux Falls residents should act quickly to mitigate the risks associated with mold exposure.

SIOUX FALLS, S.D. (Dakota News Now) - When we turn back the clocks it’s time to turn up the heat in gyms across the country because basketball season is right around the corner.

And it will start in a big way for NCAA Division One tomorrow at the Sanford Pentagon.

The venue will host the “Field of 68 Opening Day Showcase” featuring three mid-major games capped off by South Dakota State taking the floor in the evening.

It’s the brainchild of longtime college basketball reporter Jeff Goodman who runs the Field of 68 media network and wanted to kick the college hoops season off in a special way.

Among the games tomorrow is former SDSU head coach Scott Nagy making his debut as Southern Illinois new head coach against the College of Charleston.

Which begs an obvious question.

Did Goodman try to get Nagy to square off against the South Dakota State program he coached for 21 seasons from 1995-2016?!

“Of course I tried! I was unsuccessful! And with Scott he‘s too nice a human being to try to convince him. It was like once he said no the first time, that was it! You’re not going to. That dude is the nicest guy in this business.” Goodman said of his efforts to get Nagy to play SDSU in the opener.

Nagy will make his debut with the Salukis against the College of Charleston at 11:00 AM. After that the University of Saint Louis will face Santa Clara at 2:00 PM. The event will wrap up at 5:00 PM with SDSU taking on McNeese State, each coming off seasons in which they qualified for the NCAA Tournament.

“We‘ve wanted to do something like this for a while because, frankly, college basketball starts off without a bang. I mean there‘s no good games, there all ’buy' games. I‘ve complained about it for years and we felt like we could help and get some mid-major games together and that‘s what we’ve been fortunate to do.” Goodman says.

If you can’t make it out to the Pentagon all the games will be streamed on the Field of 68’s YouTube and X (formerly Twitter) platforms.

BROOKINGS — After consecutive weeks of hard-fought, down-to-the-wire, heart-pumping, nationally-televised thrillers against rivals North Dakota State and South Dakota, the third-ranked Jackrabbits had something of a reprieve on Saturday at Dana J. Dykhouse Stadium when they faced Murray State.

The Racers came in winless in Missouri Valley Conference play this year and with a 5-25 record over the last three seasons. The Jacks were 42.5-point favorites.

So nothing about SDSU's 52-6 victory in front of 16,376 fans (the Jacks' first non-sellout of the season) was surprising or especially outstanding. They did what they were supposed to do against an inferior team.

A defense that has been dominant continued to be so. An offense that had scored just 23 points in regulation in their last two games got on track and racked up nearly 600 total yards. They did not turn the ball over and had just 35 yards in penalties.

Jackrabbits improve to 7-2 with win over Valley's last-place squad

So while this win was expected to come easily and did, there's still value in it, and not just in that coaches were able to empty the bench and give meaningful reps to players who hadn't seen many.

With the Jackrabbits' most challenging games behind them, this win should set the tone for the rest of the regular season.

SDSU (7-2, 4-1 MVFC) finishes up at North Dakota, at home against Southern Illinois and at Missouri State. None of these games should be easy, especially the finale against a 7-2 Bears squad. But the Jacks will be favored in all three of them, and none will have the hype or rivalry attachments that the last two games did.

If the Jacks can replicate the formula from Saturday's comfortable victory over the season's final month, they're probably going to end up right where they want to.

"It started on Monday in practice," said center Gus Miller. "You can never (disrespect) an opponent because the game will disrespect you. Our coaches are always talking to us, making sure in these kind of games we focus on ourselves, focus on basic techniques and make sure we're not overlooking anything."

In that regard, the Jacks certainly took care of business.

Jacks’ big stable of backs shows off in home rout of Racers

For the first time all season, the South Dakota State backfield was available in full force on Saturday afternoon. And lowly Murray State was on the wrong end of it.

By Marcus Traxler

They accumulated 595 yards of total offense — 343 of them on the ground. Angel Johnson, Amar Johnson, Chase Mason, Maxwell Woods and Kirby Vorhees all had rushing touchdowns. Mason and Mark Gronowski each threw touchdown passes. The defense kept Murray State out of the end zone and limited them to a mere 236 total yards.

There wasn't much evidence of the Jackrabbits taking it easy or coming out flat, but coach Jimmy Rogers said even though his team largely executed well, they didn't have the same pregame fire and excitement to play that he's used to.

"I'll watch the film when it comes to the execution, because it felt like there was a lack of energy, just in the entire stadium," Rogers said. "Just looking at (the players), I see them so much in practice that I kind of know what to expect when I watch them and their energy level. I was happy with how we played but there's plenty to clean up. We need to be crisper and better next Saturday."

That will be against a UND squad that looked strong early in the season but has lost consecutive games, against Youngstown State and, on Saturday, lowly Indiana State. Those two were both on the road, however, and the Hawks are a different team in the Alerus Center, where they'll host SDSU next week. UND beat No. 8 Montana at home earlier this year.

It'll be SDSU's third game against one of their Dakota rivals in the last four weeks, but getting Saturday's low-stress tussle with the Racers in between should help them.

"It was a physical couple of weeks and very close games," safety Tucker Large said of the games against NDSU (a 13-9 loss) and USD (a 20-17 overtime win). "So this is definitely a confidence booster for our team. It was good for our offense to get those yards and good to see our defense get some young guys in there and flying around, having fun and being themselves.

"Coach Rogers does a great job of making it the Jacks vs. the Jacks, every game, no matter who our opponent is," Large added. "We want to be our best selves. We know our standard and if we execute that good things will happen."

SIOUX FALLS, S.D. – McNeese basketball head coach Will Wade warned the first few games of the season would be a period to get the new group of players acclimated to each other.

That proved to be true on Monday at The Field of 68 Season Opener Showcase where South Dakota State held off the talented Cowboys, 80-73, to open up the 2024-25 season.

Alyn Breed made his McNeese debut by scoring a game-high 18 points while Javohn Garcia added 15 and Christian Shumate 11.

McNeese made just 39 percent of its shots from the field, hitting 23 of 59, and sank 7 of 26 from long range for 27 percent. The Cowboys were outrebounded by a 43-29 margin including 12-8 on the offensive glass.

The Jackrabbits, the defending Summit League champions, were led by an 18-point performance from Joe Saylor while Oscar Cluff and Owen Larson each scored 14. Stoney Hadnot added 12 to round out the double-figure scorers.

Larson and Sayler combined to hit 8 of 16 from 3-point range while Larson’s trey with 42 seconds to play proved to be the dagger as the Cowboys were attempting to rally for the late game win.

Overall, SDSU made 46 percent from the field (28-61) and 12 of 35 from long range for 34 percent. In the second half, the Jackrabbits made 57 percent of their shots (16-28).

The game was tied 33-33 at the half when McNeese got back-to-back three-point baskets from DJ Richards, who finished with nine points on the night.

The Cowboys scored the first six points of the second half behind 3s from Breed and Garcia but SDSU rallied back to tie the game at 41-41 with 17:10 to play following a Larson fast-break layup.

A couple of free throws and a Joe Charles dunk put McNeese back on top 45-41 and the lead was 48-46 at the 15:01 mark after a couple of Richards freebies.

The Jackrabbits answered with an 8-0 run, started by a 3 from Jackson, and led 54-58 with 13:18 to play. The lead grew to 59-59 three minutes later and was 66-57 with 7:36 remaining when the Cowboys began to claw back.

Charles and Garcia sank consecutive 3s to pull McNeese to within 66-63, then a few minutes later and trailing 75-72, the Cowboys saw four straight jumpers fall off the mark in an attempt to pull to within 1 or tie the game.

But on the fourth miss and after an offensive rebound by Brandon Murray, Shumate was sent to the line where he made 1 of 2 and cut the gap to 75-73 with 1:29 to play.

Charles pulled in the offensive rebound on Shumate’s miss and fired up a three-pointer that was off the mark. Shumate grabbed the rebound and had an open look for a three that missed with 1:06 to play.

SDSU got the rebound and Larson sank a three with 42 seconds to play that gave the Jackrabbits a 78-73 advantage, then added another basket after a McNeese miss with 17 seconds to play.

Next up, McNeese will open its home slate on Thursday night at 7:30 against Biblical Studies in the second game of a double-header with the Cowgirls.

Researchers test for ‘forever chemicals’ in Big Sioux River

The murky brown Big Sioux River consistently receives poor marks for its water quality, but eastern South Dakota water systems near the river don’t know if that pollution includes “forever chemicals.”

To find out, researchers from South Dakota Mines are testing for per- and polyfluoroalkyl substances (PFAS) at the behest of the East Dakota Water Development District.

The study will cost the district at least $100,000 to test 11 sites from northeast South Dakota to the Iowa border past Sioux Falls, including four more sample runs throughout 2025.

“Ideally, we’ll find nothing, and we’ll have spent a lot of money to do that,” said Jay Gilbertson, district manager. “But right now, we don’t know if there is PFAS in the river. It’s hard to be proactive and plan if you don’t have information.”

A separate, federally funded project through the South Dakota Department of Agriculture and Natural Resources was announced earlier this year to assess and clean up contaminated sites in South Dakota. Falls Park, quarry lake and a former rubble site just south of the Sioux Empire Fairgrounds in Sioux Falls are being tested for PFAS and other contaminants that pose risks to the Big Sioux River. The project is in the planning phase, and testing has not started yet.

The chemicals have been used in industry and consumer products since the 1940s and don’t break down easily in the environment or in the human body. Research indicates PFAS exposure may be linked to negative developmental and reproductive effects, and an increased risk of some cancers.

The federal government established new limits on some types of PFAS in drinking water earlier this year. Those limits apply specifically to treated drinking water. The limits do not apply to chemicals found in waterways.

Water treatment plants along the Big Sioux River can pull directly from the river or pull from underground wells near the river. Sioux Falls is the only water system that pulls water from the Big Sioux River, but the city rarely uses the river as a water source.

More states ban PFAS, or ‘forever chemicals,’ in more products

An ongoing study indicates that, under the right conditions, Big Sioux River water can infiltrate wells near the river.

Gilbertson saw water treatment plants in southeastern South Dakota along the Big Sioux River several years ago experience an influx of hard water in their systems. He said the culprit was Lake Poinsett, near Watertown, which began discharging water into the Big Sioux that seeped into underground wells used by some treatment plants downstream.

That’s why it’s “better to go looking for it,” Gilbertson said, so water treatment plants can prepare solutions before contamination becomes a crisis.

If PFAS is found in the Big Sioux River, the water district can inform public water suppliers, Gilbertson added.

“Maybe we tell them, if they can, not to use the well that’s so close to the river; reactivate one a little farther away,” Gilbertson said. “As a result, they might not technically have a problem and have to stop serving customers because they stopped using the water before it became a problem.”

PFAS has been detected in wells near Ellsworth Air Force Base at Box Elder, as well as Sioux Falls Regional Airport and its co-located Air National Guard base, where the chemicals were used in firefighting foam. The forever chemical has also been detected in wells at National Guard facilities near Custer and in Rapid City, and in three private wells in South Dakota.

Sioux Falls suspended 21 of its wells suspected of PFAS contamination after the detection. Since then, all raw water samples — which can include the Big Sioux River at times — have been tested for PFAS compounds, said Sioux Falls Water Superintendent Chris Myers in an emailed statement. The city has not detected PFAS in those sources.

But even if Sioux Falls doesn’t find PFAS in river tests, that doesn’t mean there isn’t PFAS in the river: It just means it’s not immediately upstream, Gilbertson said.

“It doesn’t necessarily preclude it from the upper basin or below the city,” he added.

Most recently, a preliminary sample of Mount Rushmore National Memorial’s drinking water had levels of PFAS more than two times higher than the new federal limit.

The South Dakota Association of Rural Water Systems is testing 40 rural water systems throughout the state for PFAS chemicals in cooperation with the EPA. Cities are also testing their water and submitting it to the EPA.

Lisa Kunza, associate professor in chemistry, biology and health sciences and director of the Center for Sustainable Solutions at South Dakota Mines in Rapid City, helped collect the initial Big Sioux River samples in September.

Kunza and her team research PFAS contamination impacts on water resources, agriculture and human health. They’re looking for 40 PFAS compounds in the water. She said the initial test results could take a month to several months to get back from the lab.
