Technicat, Inc, a new company in Corona, CA has developed a catalytic water treatment device. Here's some exerpts from the newspaper articles about their experiment on Lake Elsinore: ========================== 02-Jul-95 =================================== High-tech boat attacking lake scum By Sandy Stokes The Press-Enterprise LAKE ELSINORE Boat wakes on Lake Elsinore are frosty white, not the bile-colored froth that boats were churning up a year ago. And objects can be seen more than two feet below the water's surface - another change from last summer, when anything immersed disappeared instantly in green slime. What is happening to old "Lake Smell-some-more" and its festering summer algae which used to turn the town into one of the stinkiest places west of the Salton Sea? Part of the answer might be under the hull of a pontoon boat. Since May 18, it has been chugging along slowly from morning to night Monday through Saturday, systematically "treating" the water in Lake Elsinore. The boat owner, Don Pavlis of Corona, said his experimental "Lakesaver Cat" pontoon boat is effective in keeping the lake from turning slimy green and smelly. [...] "By changing the composition of the nutrients in the lake," Pavlis said, "we're interrupting the food chain, and the algae dies." Technicat's catalytic water treatment device uses a combination of metals that react with the ions in the pollutants and change their electrical charges, Pavlis said. [...] The company's data concludes that the algae population in the treated areas of the lake is 50 to 75 percent less than in water that was not treated. [...] Local lake watchers have seen claims for surefire algae cures sputter and die over the years, so Technicat's offering is being greeted with cautious optimism and a wait-and-see attitude. [...] "The city's not in a position to jump up and down and say we've found a solution," said Dick Watenpaugh, Lake Elsinore's manager of special projects. Technicat, he said, has received city approval for its experiment on Lake Elsinore. The water treatment is not adding any substance to the city-owned lake and the experiment is not costing the city a penny. "I'm no scientist, but from a logical point of view," Watenpaugh said, "I would say . . . if they make it through July and there are no algae bloom you'd have to consider what they're doing may be having an impact." ========================== 07-Jul-95: ========================== Credit for cleaner lake debated DAVE STREGE Outdoors LAKE ELSINORE Something is different about the lake sometimes referred to as Lake Smellsomemore. It doesn't stink. [...] "It's as fine as I've ever seen it," said Ron Satter, of Four Corner Liquor, who has lived in Lake Elsinore for 24 years. "We're selling more bait and tackle, and our tourism is up. The water clarity is better than it's been in years. We've had no smell and kids are swimming in it and not turning green." [...] So what happened? Pick a theory. Don Pavlis said the non-toxic treatments of the lake by his newly formed company performed during the month of June negated 50 to 75 percent of the algae during that period. For six hours a day, six days a week, employees of Technicat Inc. took turns "Plowing" the lake back and forth in the Lakesaver Cat, a 24-foot pontoon boat equipped with five underwater catalysts. [...] Mother Nature being good to the people of Lake Elsinore is how assistant city manager Dick Watenpaugh explained the lake's turnaround. [...] Conditioning the lake with chemicals that eat phosphates had been the most effective means in the past. Dredging was talked about but would cost $20 million. An aeration system is another option. It, too, is costly. Already, two aerators are at work in the lake. A Lakesaver Cat would cost the city $150,000 and pay for itself within a year, Pavlis said. But the city isn't convinced it is doing what Pavlis says it is doing. Watenpaugh said if hard scientific data showed the process was eliminating phosphates, a constant ingredient during runoffs, the city would pursue Pavlis's invention. "The algae is what we promised to take care of, not the phosphates," said Ken Kirsch, vice-president of Technicat. "The phosphate problem will be corrected as the algae is corrected." [...] Pavlis said he remains grateful to the city for allowing him to experiment on the lake but can't understand why it won't give him any credit or consider his method. [...] Dawson theorized that the 23 inches of winter rain flushed the lake out, with runoffs from subsequent storms bringing in cleaner water each time. [...] Bud Attridge, a Lake Elsinore resident for, 16 years, said the wind that the lake had been missing the previous three years returned this year and aerated the lake naturally, [...] Well, whatever the reason, Lake Smellsnomore is flourishing and the algae isn't. Best enjoy it while it lasts. ============ THE PRESS-ENTERPRISE - Friday, July 21, 1995 - B-3: ============ Algae behaves; lake is awash with boats The clear water is helping tourism rebound in Elsinore, and that means cash. Will the green scum stay subdued? Stay tuned. By Sandy Stokes The Press-Enterprise LAKE ELSINORE Lake Elsinore has been generating more greenbacks than green slime this summer. The formerly algae-infested lake sparkles like an aquamarine gem and draws 300 to 400 boaters every Saturday and Sunday more than three times the number of boaters it drew last year. So far this season, the city has collected $99,300 in boat launch and day use fees, said Dick Wattenpaugh, the city's manager of special projects. If the trend continues, the lake could recoup at least one-third of the $435,000 the city expects to spend on maintenance and lake police patrol this year. This time last year the lake had generated only $21,855. [...] Last summer Lake Elsinore's algae infestation was raising a stink and covering boats, swimmers, ducks and anything else that went into it with green scum. The city's marine biologist, Pat Kilroy, said he's not sure why the lake looks so good this summer. Torrential storms last winter flushed the lake for the first time in 15 years and may have washed away some of the algae. But the flushing alone can't explain the good water quality, Kilroy said. [...] One lake-scouring program the city is watching is an experimental pontoon boat that has been cruising the lake every day since May. Technicat Inc., a company that specializes in water treatment for agriculture, was granted permission by the city to try its Lakesaver Cat algae control boat on Lake Elsinore. Technicat officials say the boat's water treatment cartridges contain a metal that changes the electrical charge of ions in the phosphates and turns it into a form the algae can't use for food. [...] City officials are cautiously optimistic about the Technicat experiment. The lake looks good, but "it's too soon to say that its the Lakesaver Cat lowering the algae," Kilroy said. When the company finishes its experiment this month, the city will conduct tests to measure the amount of algae in the water. "Algal blooms come and go for a variety of factors that are not well understood," he said. Water that is pristine and sparkling this week could suddenly turn putrid green if the algae decides its time to bloom. [...] ===================== Lakesaver boat leaving clean lake ===================== The experiment ends this weekend. The boat owner predicts algae will return after the departure. By Sandy Stoke The Press-Enterprise LAKE ELSINORE Lake Elsinore will not keep its frosty white boat wakes and sparkling algae-free look much longer predicts Don Pavlis, chief executive officer of Technicat Inc. [...] Pavlis says his experiment has proven that the prototype Lakesaver Cat boat is effective. July is almost over and there was no nasty algae bloom. But if Pavlis' hunch is right, the sparkling lake will revert to the old fetid, bile-colored "Lake Smell-some-more" in a week or two as the algae takes hold again. Nevertheless, the experiment, he says "proves it is possible to control the algae and eliminate the odor and fish kills on a large body of water," using a relatively inexpensive technology. [...] The lake looks very good, therefore, "the Lakesaver Cat may be doing something," acknowledged Assistant City Manager Dick Watenpaugh. However, he is not ready to laud the boat as an algae cure. At the close of Technicat's experiment, he said, the city will conduct its own tests on the lake to measure nutrient content and algae. He said he hopes that the city's test results uphold Technicat's findings because, "it could be an inexpensive way to treat the lake," Watenpaugh said. Technicat's specially equipped boat cost about $150,000. The company's main business involves using the same method to treat water for agricultural users, Pavlis said. Technicat has successfully eliminated algae from irrigation ponds covering several acres, he said, but has never before attempted to control algae on a body of water as large as the 7-square-mile Lake Elsinore. [...] ============= B-2 Friday, August 4, 1995 - THE PRESS-ENTERPRISE ============= Officials doubt boat cleaned Lake Elsinore: No contract By Sandy Stokes The Press-Enterprise LAKE ELSINORE Water experts on the technical committee of the Lake Elsinore Management Authority on Thursday couldn't figure out the reason for the sparkling clean water in Lake Elsinore this summer. They can't say why the lake's notorious algae are not sliming the water and fouling the air. Still, they're not ready to give the credit to the experimental Lakesaver Cat boat that pushed water treatment cartridges through the lake during a two-month experiment that ended Saturday. [...] "In the absence of any hard data, the technical committee would agree it is unwise at this time for the city to spend the money," said Burnie Cavender, the management authority's executive director. Don Pavlis, chief executive officer of Technicat, contends that the appearance of the lake is proof enough. He said: "If it walks like a duck, quacks like a duck, has a yellow bill and webbed feet, it might be a duck." [...] Also on Thursday the committee reviewed the first batch of lake monitoring results from the engineering firm Black & Veatch. The authority hired the firm earlier this year to monitor the levels of the phosphates and other nutrients that feed the troublesome algae. [...] The monitoring is the first phase of a lake cleanup plan proposed by Black & Veatch. The plan calls for lake aeration, algae harvesting, adding aquatic plants to starve out algae, stocking algae-eating fish and using reclaimed water, treated if necessary, to keep the lake level constant. The project would cost about $8 million over the next nine years. [...] "Maybe we have a nitrogen limiting situation," Anderson said. "Maybe, with any luck, we're not going to have an algae disaster this year. Pavlis, of Technicat said nitrogen reduction is one of the effects of his company's water treatment program. According to Bud Attridge, president of the Elsinore Valley Municipal Water District board, chemical studies and experiments are a waste of time and money. He said there is a simple, natural reason the lake does not have a rank crop of algae this year: "The wind has been blowing," he said. "You can laugh if you want to, but any old timer who lives on the lake can tell you that the algae doesn't grow when the wind blows," he said. "The wind aerates the lake." Attridge has lived on the shore of the lake for more than 15 years. He said he's observed that algae blooms occur only in years that haven't been windy. As proof of his theory, he point out that there have been whitecaps on the lake nearly every afternoon this year. ============ THE PRESS-ENTERPRISE - Monday, August 7, 1995 - B-3 ============ Letting the Lake Elsinore secret out LAKE ELSINORE Hundreds of weekend water-skiers have discovered that Lake Elsinore does not stink. [...] The lake certainly has been a mess in past summers. So far, this year is different but city officials nervously monitor the water for the dreaded signs of algae. Heavy rains last winter and spring filled the lake with fresh water. The lake now has an outflow channel that prevents flooding and improves circulation. Lake Elsinore has fought dreaded blooms of algae for years. This year, Technicat Inc. of Corona operated an experimental pontoon boat on the water for two months. The Lakesaver Cat treated the water as it flowed through cartridges. The company, which hopes to sell the process to the city, maintained that the treatment kept algae from blooming. One thing is certain: the lake didn't turn the usual rancid summertime green while the pontoon boat worked the water. [...] =============================== 08-Aug-95: =============================== Algae sightings on Lake Elsinore have been rare this summer, and the characteristic stench that accompanies algae blooms has not been detected. Yet in the murky depths of the sparkling azure lake, the green slime began choking the life out of its first summer victims this week. City officials hope this week's fish kill does not signal the start of another algae disaster, which could kill off the lake's new tourist boom as well. So far, the fish kill is minor, said Assistant City Manager Dick Watenpaugh. Monday was the first day there was a scattering of lifeless fish, suffocated by the algae during the night, floating on the lake surface. By Thursday, city workers had scooped 3,000 to 4,000 pounds of dead fish from the lake. Water quality experts assembled by the Lake Elsinore Management Authority have been scratching their heads trying to figure out why the algae have been lying low. The experts have been skeptical of the success claimed by Technicat Inc., a Corona firm that operated an experimental water treatment boat on the lake for two months this summer, saying there is no scientific data to support Technicat's claim that it controlled algae growth. [...] "Nature has been kind to us this year," Watenpaugh said, because blooming algae have not reached the lake's surface to foul the water and air above it. Despite the lake's pristine appearance, the water is rich with the phosphorus that causes algae to thrive. The phosphorus, which acts as a fertilizer, comes into the lake from the San Jacinto River. The 700-square-mile San Jacinto River watershed collects storm runoff from Hemet, Moreno Valley and San Jacinto and dairy land between those communities. [...] During July, when about 700 boats were on the lake every weekend, the city collected $46,376 in lake-use fees, according to Community Services Department figures. A year ago during July, when the lake surface had far fewer boaters and swimmers, only $14,385 was collected. [...] ========== Lake Elsinore's slime slips into killing mode ========== By Sandy Stokes The Press-Enterprise LAKE ELSINORE Algae cause water along the shore of Lake Elsinore to turn green.
