Man Does Unspeakable Thing in Co-Worker’s Water Bottle

Water Testing BlogArsenic, Arsenic Test, Arsenic in Water, Bottled Water, Cyanide, Ground Water, Home Water Testing, Lead, Metals, Nitrate, Nitrite, Water Quality Testing, Water Testing, Well Water, mercury

We have all heard the stories about people having date rape drugs slipped into their drinks while out at bars and nightclubs, but how many have heard of THIS? A male co-worker put his own…. ‘seed’…. into a female co-worker’s water bottle. Twice.

Just… Wow. What a flippin’ disgusting individual!

SANTA ANA, Calif. (KABC) — A 31-year-old Fullerton man was arrested on Tuesday for allegedly ejaculating twice into a co-worker’s water bottle.

Authorities said Michael Kevin Lallana was linked through DNA to the crimes.

Lallana allegedly entered the victim’s office and deposited his ejaculation into a water bottle that was on her desk in January. Police said the unsuspecting victim later drank the water, which made her feel sick, so she threw it away.

In April, investigators said Lallana did the same thing, but this time, the victim saved the water bottle and sent it to a private lab for testing. She then reported the results to the Orange Police Department.

Lallana is charged with two misdemeanor counts each of releasing an offensive material in a public place and assault, with sentencing allegations for committing a crime for sexual gratification.

If convicted, Lallana faces a maximum of three years in jail with mandatory sex offender registration. He is free on $500 bond and will be arraigned next month. ( source )

If this little bit of news does not make you want to take proper precautions to guard your water, whether in the bottle you leave on your desk at the office or as the drinking water that comes up from the aquifer and into your home, then perhaps nothing will.

Do you have control over the quality of the water in the aquifer supplying your well? Most likely not, but you always have the chance and opportunity to test the quality of water for unwanted contaminants. Periodic use of a well water test kit helps to ensure that no changes in the quality of your well water have taken place.

What sort of well water testing should well owners consider? At the very least we suggest they test for naturally occurring contaminants such as bacteria, nitrates/nitrates, heavy metals like mercury and lead, arsenic, etc.

Huh? Test for arsenic? Why? Is someone trying to poison us? Most likely not, but we have good reasons to suggest well owners test their water for arsenic. If you want to know why arsenic testing for well owners makes sense, take a look at Arsenic-Test-Kit.Com and ArsenicQuick.Com.

Getting back to the topic of well water testing, the United States Environmental Protection Agency as well as public health officials on State and Local levels urge private well owners to have their well water tested by a certified water testing laboratory annually. Qualified water testing labs like National Testing Laboratories typically provide reliable test results in under two weeks.

Removing Chlorine From Garden Water

Water Testing BlogChlorine, Chlorine Testing, Combined Chlorine, Environmental, Free Chlorine, Metals, Total Chlorine, Water Filter

Looking for a way to lower the amount of free chlorine and chloramines in the water you use in the garden… but don’t want the hassle of installing a complicated water filter?

If so, then we suggest you consider the Green Knight Hydroponic Dechlorinating Filter.

Functioning as an easily installed inline filter, the Green Knight screws right onto the average 3/4″ garden hose and promotes healthy plant growth by effectively reducing and/or removing potentially harmful chlorine from the water and also contains quartz crystals which aid plants’ absorption of vital nutrients.

Rainshow’r Green Knight uses a polyester pre-filter to catch sediment and then allows water to pass through 2 pounds of specially blended KDF55, 2 ounces of quartz crystal, and a final polishing stage which contains KDF73 filament media.

This product also comes with a sturdy 3-foot vinyl hose so that people can reap the benefits of the chlorine filter near the spigot/faucet w/o having to wrestle with a full-length garden hose. This works out well for rinsing off metal tools, washing mud off of dogs, etc.

Oh, and we learned something new while researching this product: People have found that reducing chlorine levels in rinse and wash water can greatly extend the life and luster of organic carnuba wax jobs on cars, boats, RV’s, etc.

Specific product details of the Rainshow’r Green Knight:


Test for Free & Total Chlorine


Test for Chlorine & Hardness

  • Testing has shown that the unit removes 85% – 90% of Free Available Chlorine (FAC)
  • Testing has shown that the unit also reduces chloramine concentrations by 65% – 75%
  • Life expectancy: 30,000 gallons of source water assuming ‘average’ chlorine concentrations
  • Suggested flow rate: Approximately 2 ppm
  • Temperature rating: From 40F up to 110F
  • Maximum pressure rating: 100 psi
  • Freezing will cause irreparable damage to the unit, as will not running water through the unit at least twice a month after its first use.

Will the Rainshow’r Green Knight work as a drinking water filter?

Rainshow’r, the manufacturer of Green Knight Hydroponic Dechlorinating Filter designed this product for use in the garden and for outdoor applications, not for use a device to make water potable.

It lacks sufficient filter media capable of removing particulate matter and other contaminants such as organic chemicals, heavy metals (lead, iron, copper, mercury, etc.) and bacteria from source water.

6-Stage Inline Filter for Arsenic

Water Testing BlogArsenic, Arsenic Test, Arsenic in Water, Chlorine, Copper, Lead, Metals, Pesticide, Trihalomethane, Water Filter, mercury

This multi-stage (six) inline filter does a lot more than just remove arsenic from water at a rate of up to 1 gallon per minute, a rate perfect for use with water fountains, bottleless water coolers, commercial coffeemakers, and ice machines. It uses all six of its filtration layers to effectively remove a number of drinking water contaminants.

  • In stages 1 and 6 water flows through pre and post one – micron filters capable of removing suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other types of unwanted matter.

  • In stage 2 water flows through a specially engineered arsenic removal/reduction media.

  • In stages 3 and 4 water flows through a media bed comprised of high purity KDF-55D ®, and KDF-85D ®, which operate using electrochemical and spontaneous oxidation/reduction (REDOX) principles. The combination of these two special media completely oxidizes any chlorine in the water.

    As an added bonus, heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved metals also get removed/reduced during this stage of filtration.

    While some KDF media beds can harbor unwanted bacteria, studies have shown that this particular unit reduces the likelihood of bacteria growth by as much as 90%, thus eliminating the need for silver, an element considered by some to pose health risks.

    Worried about the possible addition of copper or zinc to the water in any significant amount? On a sample of water containing 2.3 ppm chlorinated water, testing after filtration detected <0.05 mg/l copper and only 0.46 mg/l zinc. The EPA has set the aesthetic levels for copper at 1.0 mg/l and 5.0 mg/l for zinc. Additionally, the human body requires both zinc and copper for good health. The FDA recommends a daily intake of 15 mg of zinc and 2 mg of copper.

  • In the fifth stage of filtration, water flows through granulated activated carbon (GAC) which adsorbs a wide variety of organic contaminants, such as any remaining chlorine (99.9%), chemicals linked to cancer such as Trihalomethanes and benzene, pesticides, herbicides, insecticides, volatile organic compounds (VOC’s), PCB’s, MTBE’s and a laundry list of other chemical contaminants that may exist in your source (i.e. tap or well) water.

What about replacement filters? Will I have difficulty finding them? Highly unlikely! The manufacturer of this inline arsenic filter, Crystal Quest has existed in one form or another in the commercial water purification industry for more than thirty years.

You can order replacement filters for the inline arsenic filter on FilterWater.Com, a leading online vendor of water quality improvement products from Crystal Quest and other manufacturers.

Summary of NSF Water Filter Standards

Water Testing BlogArsenic, Bacteria, Chlorine, Hardness, Metals, THM, Trihalomethane, UV Sterilizer, Water Filter, mercury

If we had a nickel for every single time someone asked us what NSF 42, 44, 53, 55, 58, 62 and 177 meant… we’d have a huge pile of nickels and STILL not have enough money for that diamond-plated, gold-encrusted, platinum embossed drinking fountain w/ the GIANT water purification FACTORY attached to it from the other side of the wall.

water filter pitchers

NSF/ANSI Standard 42: Drinking water filtration systems that are certified to this standard remove chlorine and sediment/particles from water for the purpose of improving its look, smell and taste. The design of these filter do NOT lend themselves to the removal or reduction of health-related contaminants.

NSF/ANSI Standard 44: Water treatment systems certified to this standard typically function as cation exchange water softeners designed to reduce or eliminate water hardness (i.e. calcium and/or magnesium). Water filters designed to remove barium and radium may also certify to this standard.

water softeners

NSF/ANSI Standard 53: Water purifiers certifying to this standard have designs that remove health-related contaminants such as waterborne organisms and industrial chemicals. Cryptosporidium, giardia, volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl ether) and trihalomethane compounds (THMs) fit into one of those categories or the other.

NSF/ANSI Standard 55: Devices rated to this standard function as point of use (POU) or point of entry (POE) ultraviolet microbiological water treatment systems. These water treatment systems feature designs which disinfect microorganisms (such as bacteria and viruses) potentially present in water.

UV Sterilizers

NSF/ANSI Standard 58: Typically one will find reverse osmosis water systems (RO) certified to this standard. Devices in this category will normally have the ability to fully remove organic contaminants, but may only partially remove inorganic compounds and heavy metals.

NSF/ANSI Standard 62: Certified to this standard one will typically find water distillers. The process of distillation removes a wider range of drinking water contaminants than all other methods of drinking water purification. Arsenic, mercury and bacteria all get eliminated through the use of water distillation systems.

shower filters

NSF/ANSI Standard 177: Water filtration units certified to this standard function as shower head filters designed to remove chlorine from water.

SenSafe Lead in Paint Test Kit

Water Testing BlogCopper, Lead, Metals, Testing Devices, Water Quality Testing, Water Testing

Lead in Paint Test Kit

Why do you see a blog posting dealing with testing for lead in paint on a web site dedicated to water quality and water quality? Simple: The folks responsible for this site care about the health and safety of families and want them to live lead-free lives whenever possible.

Why should a family or person have to wonder whether or not the paint covering their furniture, window sills, radiators, walls, baseboards, etc. contains harmful lead when a simple, easy-to-use test kit for lead in paint like the LEADQuick Paint Home Test Kit contains 25 tests and each test takes only minutes to perform.

Using visual detection method which makes use of a new & improved red-green color development technology, LEADQuick Paint Home Test Kit detects the presence of lead on surfaces including wood, plaster, drywall, and metal.

The LEADQuick Paint Home Test Kit includes:

  • 10 – Testing Tubes: Small polystyrene test tubes
  • 1 – eXact® Reagent Acid-1 in a dropper bottle
  • 1 – eXact® Reagent PB-2 in a dropper bottle
  • 1 – eXact® Strip PB-3P bottle of 50 strips
  • 1 – eXact® Strip PB-4 bottle of 25 strips
  • 1 – Foam Test Tube Holder
  • 1 – Instruction Manual
  • 1 – Lead Paint Drywall ‘Standard’

While newer homes must pass certification tests prior to sale and may not contain lead-based paints, the law does not always require older homes that have passed down from family member to family member an/or as rental properties that have not changed owners in many years to comply with newer lead regulations.

Testing for Lead in Water

Given all the publicity that lead in water contamination has received in recent years, it should come as no surprise that people have interest in testing their drinking water for lead.

Remember: At one point copper piping joined by solder containing lead went into pretty much every home and office.

Got interest in testing for other metals in your drinking water? No problem. The following test kits will make that task a breeze!

Question: How Can I Filter Hot Water?

Water Testing BlogHardness, Metals, Water Filter, Water Quality Testing, Water Testing, manganese

The other day we received an email from ErnieB_121 who had a question about filtering hot water before use in his restaurant.

Hi, I hope you can help me with a problem I’m having in my restaurant. I’m getting ridiculous amounts of buildup clogging the prefilter things on the hot water line of my dishwasher and tell the truth I’m sick of replacing the d#amn things. Not that they cost a lot, but it’s a pain in the #ass to get to them and one day I’m afraid I might strip the fittings and then I’ll REALLY have a problem. So do they make filters for hot water lines? All the filters I’ve seen in stores work for cold water lines only. Thanks. ErnieB_121

Thank you very much, Ernie, for a colorful email. Ha ha. We can totally understand your frustration with having to replace hard-to-reach inline filters.

We believe you may find a filter housing and filter for your application at WaterFilters.Net, an online retailer of commercial and residential water filtration products. When last we checked they carried three different styles of housings for hot water filters and a good assortment of filters to go in them.

One thing you failed to mention Ernie… Where does the residue clogging your lines come from? What does it consist of? Calcium? Iron? Manganese? Radioactive sludge from the planet Mars? Not poking fun at you, just trying to make a point: you need to test your hot water — after it cools — and find out what sort of deposits you have so you can purchase the correct filter for your needs.

The links below will take you to products you may find useful when attempting to determine what contaminant(s) you have in your hot water line:

Water Filter System for People w/ Compromised Immune Systems

Water Testing BlogArsenic, Bacteria, Copper, Lead, Metals, Nitrate, Personal Water Filter, Reverse Osmosis, TDS, Water Filter

We recently received an email inquiry from Lisa containing a question about water treatment systems for people with compromised immune systems.

My son has just been diagnoses with an immune deficiency, and I should be sterilizing his drinking water -which I am doing by boiling for him. I am wondering if distilled or reverse osmosis, bottled water would effectively remove bacteria from the water, and be a safe alternative. Would one be better then the other.

Thank you for your time,

Lisa

Thank you, Lisa, for your question and it pains us to learn of your son’s condition. We hope that modern medicine can find a way to help your son live a long and healthy life.

Regarding your question about the best way to sterilize water for people with compromised immune systems, the EPA and CDC co-released a document back in 1995 that gives a lot of useful information on the topic entitled Guidance for People with Severely Weakened Immune Systems.

Below you will find excerpts from that document relating directly to the questions you asked:

  • Cryptosporidium has caused several large waterborne disease outbreaks of gastrointestinal illness, with symptoms that include diarrhea, nausea, and/or stomach cramps. People with severely weakened immune systems (that is, severely immunocompromised) are likely to have more severe and more persistent symptoms than healthy individuals. Moreover, Cryptosporidium has been a contributing cause of death in some immunocompromised people.

  • Although data are not sufficient for EPA/CDC to recommend that all severely immunocompromised persons take extra caution with regards to their drinking water, individuals who wish to take extra measures to avoid waterborne Cryptosporidiosis can bring their drinking water to a full boil for one minute. Boiling water is the most effective way of killing Cryptosporidium.

  • Only point-of-use filters that remove particles one micrometer or less in diameter should be considered. Filters in this category that provide the greatest assurance of Cryptosporidium removal include those that use reverse osmosis, those labeled as “Absolute” one micrometer filters, or those labeled as certified by NSF International under standard 53 for “Cyst Removal.” …. Water treated with a point-of-use filter that meets the above criteria may not necessarily be free of organisms smaller than Cryptosporidium that could pose a health hazard for severely immunocompromised individuals.

  • Many, but not all, brands of bottled water may provide a reasonable alternative to boiling tap water. …. Any bottled water treated by distillation or reverse osmosis before bottling assures Cryptosporidium removal.

  • Neither EPA nor CDC maintains a list of point-of-use filters or bottled water brands that meet the above criteria. NSF International can provide a list of filters that meet the NSF criteria.

We suggest you take a look at the NSF Web Site to see what systems meet their requirements. In a situation like yours, you will want to make certain the product you purchase will accomplish all your objectives — and then some.

Pentek RO-3500 Reverse Osmosis System

One system we came across recently, the Pentek RO-3500 Monitored Reverse Osmosis System,

NSF Tested & Certified Standard 58 for reduction of TDS, Fluoride, Turbidity, Lead, Nitrates, Selenium, Arsenic, Copper, Cadmium, Barium, Cyst, and Radium.

The Pentek R0-3500 features the 3 stage system, one ROM-230TN membrane, a D15 sediment filter, a D20 carbon filter, and one long-reach lead-free faucet. Unit comes with a standard installation kit and instructions.

Another feature of the the Pentek RO3500 which makes it quite nice… an electronic monitoring system that keeps track of the water filters cartridges’ lifespans and informs the owner when they need replacing.

What elements does the RO-3500 Reverse Osmosis System reduce and/or eliminate? The unit has the ability to filter out the following elements as well as many other chemical compounds:

For more information on the Pentek Reverse Osmosis System mentioned above, please read its detailed specifications on FiltersFast.Com.

One final word

Use of a reverse osmosis systems does NOT guarantee the elimination of ALL possible biological contaminants since some biological contaminants have sizes smaller than the membranes in RO units can filter out.

For that reason you may want to consider adding a UV Sterilizer to your filtration setup. These devices render biological contaminants incapable of reproducing by altering their genetic structure with specific wavelengths of light.

Big Blue Filter for Iron Reduction (Pentek)

Water Testing BlogIron, Metals, Water Filter, Water Quality Testing, Water Testing, hydrogen sulfide, manganese, pH

Got a problem w/ iron in your water? If so, you have joined the millions of other folks who have the same problem.

Iron occurs naturally in the environment and as water passes across it in rock formations small amounts of iron dissolve into the water. Over time the amount of iron dissolved into the water can grow to a large amount and in too great a quantity iron in water can result in stains on fixtures, metallic taste, the formation of precipitates which can clog plumbing and filters, etc.

You can find additional information on iron in drinking water on an earlier blog posting… here

For those reasons, and more, most people prefer to filter iron out of their water before using it in their homes, schools and places of business. The Pentek RFFE20-BB Iron Reduction Filter helps people accomplish that goal.

Configured as a 20″x5″ radial flow ‘Big Blue” cartridge, the Pentek RFFE20-BB reduces iron in drinking water and has a genuine Pentek part number of 155263-03. This product effectively removes up to 3 ppm of dissolved iron from water and in doing so reduces the metallic taste caused by iron and reduces orange/brown staining found on sinks, tubs, toilets and other plumbing fixtures.

Size of Filter: 20″ x 5″, w/ actual measurements of 19 3/4″ x 4 7/8″

Optimal pre-filter water conditions:

Using the Pentek RFFE20-BB Iron Reduction Filter to treat water outside of specified limits may result in shortened filter life.
