Enkola 1: Okukulukuta kw’amayengo g’omuyaga waggulu-wansi n’okukulukuta okw’enkulungo¶

Omuyaga bwe gukulukuta okuva mu muyaga oba king tide gubooga ettaka okwetooloola oluzzi lwo: 1. Okuyingira obutereevu mu kisenge: Enkoofiira z’enzizi ezisinga ez’amayumba zirina ekifo ekifulumya empewo ekikubiddwa okusobozesa empewo okuyingira n’okufuluma ng’amazzi galinnya n’okugwa munda mu kisenge. Amazzi g’amataba bwe gamala okulinnya waggulu w’ekisenge ky’oluzzi (mu ngeri entuufu \(30\text{ okutuuka ku }45\text{ sentimita}\) [\(12\text{ okutuuka ku }18\text{ yinsi}\)] waggulu w’ettaka), amazzi g’ennyanja amazito (density \(1.025\text{ g/cm}^3\)) gayiwa butereevu wansi mu ttanka y’empewo ne gabbira mangu okuyita mu lighter empagi y’amazzi amayonjo (\(1.000\text{ g/cm}^3\)) okutuuka wansi w’oluzzi. 2. Annular Space Channeling: Ne bwe kiba nti amazzi g’amataba tegasukka ku kifundikwa, enzizi enkadde zitera okuba ne paadi za seminti ezikutuse ku ngulu oba ebifo eby’omugongo ebitaliiko grouted obubi (ekituli wakati w’ebweru wa payipu ya PVC oba ey’ekyuma n’ekinnya ky’ettaka erisimiddwa). Amazzi g’amataba ag’omunnyo gakulukuta okwetooloola payipu era ne gayita butereevu wansi ebweru w’ekisenge okuyingira mu ssirini y’oluzzi. 3. Septic-Surge Cocktail: Kubanga ebifo ebiri ku lubalama lw’ennyanja ebirina enzizi ez’obwannannyini kumpi bulijjo biba n’enkola z’obwannannyini septic systems (laba okulemererwa kw’enkola y’amazzi amakyafu) esangibwa \(15\text{ okutuuka ku }30\text{ mita}\) (\(50\text{ okutuuka ku }100\text{ ffuuti}\)) okuva, omuyaga mu kiseera kye kimu gubooga mu kifo awafulumya amazzi amakyafu era ne gutabula amazzi amakyafu g’abantu amabisi n’amazzi g’omunnyo mu nnyanja nga tegannaba kugatwala mu mutwe gw’oluzzi.

Enkola 2: Okuyingira kw’amazzi g’omunnyo okuva wansi okudda waggulu n’enkolagana ya Ghyben-Herzberg¶

Okusinziira ku Ghyben-Herzberg Relation, olw’okuba amazzi g’ennyanja \(1/40\text{th}\) (\(2.5\%\)) manene okusinga amazzi amayonjo, ku buli 1 mmita (fuuti 3.3) nti emmeeza y’amazzi amayonjo agali wansi w’ettaka eyimiridde waggulu w’obugulumivu bw’ennyanja obutuufu (\(h_f\)), lenzi y’amazzi amayonjo egaziwa mita 40 (fuuti 131) wansi w’obugulumivu bw’ennyanja (\(z_s\)) nga tonnaba kukuba nsengekera y’amazzi g’omunnyo:

Lwaki Okupampagira Okuyitiridde Kuleeta Akatyabaga "Saltwater Upconing": - Because of this 1-to-40 hydrostatic ratio, if you lower the freshwater table in your well by just 1 meter (3.3 feet) by running your well pump hard and continuously (for example, trying to pump out floodwater fast, filling a swimming pool, or irrigating after a storm), the underlying cone of deep ocean saltwater rises upward by 40 meters (131 feet) directly beneath your well screen. - Once that rising cone of dense saltwater (upconing) touches the bottom intake of your submersible well pump, your tap water turns salty within minutes. Even after you turn the pump off, it can take months or years of heavy rainfall for the freshwater lens to push that heavy saltwater cone back down.

Ekimu ku bifumo ebisinga okuba eby’obulabe oluvannyuma lw’omuyaga ogw’oku lubalama lw’ennyanja kwe kuba nti ebyuma ebisengejja enkambi ez’amangu, ebyuma ebisengejja ensuwa oba okufumba bisobola okufuula amazzi g’oluzzi olulimu omunnyo okuba amalungi okunywa.

Omutendera ku mutendera protocol okwekenneenya, okulongoosa, n’okuddaabiriza oluzzi olw’omuyaga-amataba¶

Amazzi g’amataba ag’oku lubalama lw’ennyanja bwe gamala okukendeera ddala okuva okwetooloola omutwe gw’oluzzi lwo era ng’ettaka liri bulungi okutambulirako, goberera emitendera gino United States EPA, CDC, ne National Ground Water Association (NGWA) mu mutendera gwennyini.

Omutendera 1: Obukuumi bw’amasannyalaze n’okukebera omutwe gw’oluzzi mu mubiri¶

1. Kakasa nti 240V breaker eri OFF ku main electrical panel nga tonnasemberera well house oba wellhead.
2. Kebera oba structural surge damage: Kebera oba ebisasiro by’omuyaga ebitengejja byafukamira casing y’oluzzi, byakutuka payipu ya PVC, byakutula omukutu gw’amasannyalaze, oba byannyika pressure switch ne capacitor control box.
3. Singa bbokisi efugira amasannyalaze, switch ya puleesa, oba motor ya jet-pump etali nnene yali enyweredde mu mazzi g’omunnyo: TOddamu kuzzaamu kimenya. Amazzi g’omunnyo agalekebwa munda mu bifo ebikwatagana n’amasannyalaze galeeta okufuka amangu oba omuliro gw’amasannyalaze. Laga omukozi w’oluzzi alina layisinsi oba omukugu mu by’amasannyalaze akyuse switch/control boxes ezinywera mu mazzi era agezese obuziyiza bwa ppampu enywera mu mazzi n’ekintu ekiyitibwa megohmmeter (Megger) nga tonnaddamu kugiwa maanyi.
4. Ggyawo obuveera bwonna obuzingiriddwa amataba nga omuyaga tegunnabaawo ku kifundikwa ky’oluzzi era okakasizza nti omukutu gw’empewo ogusengekeddwa teguliimu bitoomi na biwuka olwo oluzzi lusobole okussa ng’opampagira.
5. Naaba ebweru w’omutwe gw’oluzzi ne paadi ya seminti n’amazzi amayonjo amayonjo n’omubisi gwa bleach omugonvu okuggyawo ebitosi by’ennyanja n’ebisigadde ku kazambi agali kungulu.

Omutendera 2: Bypass House Plumbing era okole Throttled Salinity Purge¶

Topampagirangako mazzi ga luzzi oluvannyuma lw’okukulukuta ng’oyita mu payipu zo ez’omunda, ekyuma ekibugumya amazzi, oba ekigonza amazzi mu kiseera ky’okugezesa okusooka: 1. Kakasa nti vvaalu y’okwawula ennyumba enkulu EGGADDE kale tewali mazzi ga luzzi gayinza kuyingira mu bbugumu ly’amazzi agookya, ekyuma ekikola ice, oba ttaapu z’awaka. 2. Yunga hoosi y’olusuku ku spigot efulumya amazzi ku mabbali g’oluzzi (esangibwa ku mutwe gw’oluzzi oba wansi wa ttanka ya puleesa nga vvaalu eggalawo ennyumba enkulu). Dduka hoosi mu mwala oba ekifo eky’amayinja waakiri mita 15 ku 30 (fuuti 50 ku 100) okuva ku ttanka yo ey’amazzi amakyafu n’ekifo w’ofulumya amazzi (tobooga mu nkola yo ey’amazzi amakyafu n’enkumi n’enkumi za liita z’amazzi agalongoosa) era ng’oli wala n’emiti oba ensuku ezikwata omunnyo. 3. Throttle vvaalu y’okufulumya okutuuka ku kigero ky’okukulukuta mpola okutuuka ku kigero (20 ku 40% ku busobozi obusinga obunene): - Nga bwe kinnyonnyoddwa mu kitundu kya Ghyben-Herzberg waggulu, oluzzi lwo bwe luba mu kifo ekiwanvu eky’omusenyu ogw’oku lubalama lw’ennyanja, toggulawo vvaalu 100% nga nzigule okumala essaawa. Okupampagira mpola kuggyawo amazzi g’omunnyo amazito agaayiwa wansi mu kisenge okuva kungulu awatali kutondawo kkooni ya wansi ennyo esonseka amazzi g’ennyanja agali wansi w’ettaka waggulu okuva wansi. 4. Londoola TDS ne Turbidity buli luvannyuma lwa ddakiika 15 nga olongoosa: - Initially, water coming from a surge-overtopped well will often be turbid (muddy/cloudy) and show high salinity (\(2,000\text{ to }20,000+\text{ mg/L TDS}\)). - Pump for 30 to 60 minutes, then shut the pump off for 30 to 60 minutes to allow the freshwater aquifer to recharge the borehole laterally without upconing. - Repeat these intermittent purge-and-rest cycles until the water runs completely clear and your handheld TDS meter drops below 500 mg/L (or returns to your well's pre-storm baseline salinity).

Step 3: Shock Chlorination (Biological Disinfection)¶

Once the water purging from the wellhead spigot is clear and fresh (\(\text{TDS} < 500\text{ mg/L}\)), you must disinfect the well, pressure tank, and house plumbing to kill E. coli, Vibrio, and fecal pathogens: 1. Calculate your well water volume and required unscented household bleach (5% to 8.25% sodium hypochlorite): - Never use scented bleach, splashless bleach, laundry detergent bleach, or swimming pool cyanuric acid tablets. Use only plain, unscented NSF-60 certified liquid household chlorine bleach (typically \(5.25\%\) to \(8.25\%\) sodium hypochlorite) or calcium hypochlorite well-sanitizing pellets. - For a standard 10-to-15-centimeter (4-to-6-inch) diameter residential well holding 15 to 30 meters (50 to 100 feet) of standing water, add approximately 1.5 to 2 liters (3 to 4 pints / 0.5 gallons) of unscented household bleach per 30 meters (100 feet) of water depth to achieve a shock concentration of 100 to 200 parts per million (ppm) free chlorine. 2. Recirculate chlorine down the inside walls of the casing: - Remove the well cap (after turning off the pump breaker for safety while opening the cap, then re-energizing with care clear of bare wires). - Mix the calculated bleach in a clean 20-liter (5-gallon) bucket of fresh water and pour it into the top of the well casing. - Teeka enkomerero ennyonjo eya hoosi y’olusuku (eyungibwa ku spigot eri ku mabbali g’oluzzi) waggulu ku kisenge ky’oluzzi era odduke ppampu okumala eddakiika 15 ku 30 okunaaba amazzi agalimu chlorine wansi ku bisenge eby’okungulu ebikalu eby’ekisenge era otabule empagi y’amazzi yonna okutuusa lw’owunyiriza akawoowo ak’amaanyi aka chlorine akafuluma mu hoosi. 3. Suka amazzi aga chlorinated nga oyita mu buli ttaapu mu nnyumba: - Ggulawo vvaalu y’amazzi g’ennyumba enkulu (kuuma ebigonza amazzi n’obuwuka bwa RO ku bypass kale chlorine alimu 200-ppm aleme kusaanyaawo obuwuka bwa RO oba resin y’ekigonza). - Omu ku omu, ssaako buli ttaapu ennyogovu era eyokya, shawa, bbaafu, ne bbaafu ya hoosi ey’ebweru mu nnyumba (era buli kaabuyonjo onyige omulundi gumu) okutuusa lw’owunyiriza akawoowo akanywevu aka chlorine bleach ku buli fixture emu, olwo buli ttaapu giggale. 4. Kwata chlorine mu nkola eno okumala essaawa 12 ku 24: Tokozesa mazzi gonna, okunaaba kaabuyonjo, oba okuddukanya ebyuma mu ddirisa lino ery’okukwatagana ery’essaawa 12 ku 24. 5. Fuula chlorine mu kifo ekitali kya bulabe (SI mu ttanka yo ey’amazzi amakyafu): - Oluvannyuma lw’essaawa 12 ku 24, teeka hoosi y’olusuku ku spigot ey’ebweru era onyige oluzzi ku kkubo eriyingira mu mmotoka oba omukutu ogw’amayinja ewala n’ekifo kyo eky’amazzi amakyafu, enzizi, n’ebimera eby’okwewunda okutuusa ng’akawoowo ak’amaanyi aka chlorine kabula, olwo mu bufunze dduka ttaapu z’omunda okumala eddakiika 5 okugogola payipu z’omunda.

Omutendera 4: Okukakasa mu Laabu nga Tonnanywa¶

Ne bwe kiba nti omaze okukeberebwa shock chlorination ne TDS, tonywa mazzi okutuusa nga laboratory y’okukebera amazzi ekakasibbwa mu ssaza oba mu ggwanga ekebedde sampuli: 1.

• Lead Solder Leaching: According to USGS and US EPA studies of coastal groundwater intrusion, elevated chloride-to-sulfate mass ratios (CSMR) in brackish well water aggressively leach toxic lead out of older lead-tin plumbing solder and brass faucets into drinking water. Always run a cold-water tap for 1 to 2 minutes before drawing water, and test for lead if your home has pre-1986 copper solder joints.

Does boiling well water remove salt after a coastal storm surge or saltwater intrusion?¶

No, boiling water never removes dissolved salt, sodium, chloride, nitrates, or heavy metals. In fact, boiling brackish or salty water makes it much more dangerous to drink because pure water escapes as steam while 100 percent of the salt stays behind in the pot, increasing the salt concentration of the remaining liquid. To remove salt from drinking water at home, you must use either an electric or solar water distiller (which captures and condenses the pure steam into a separate clean container) or a Reverse Osmosis (RO) filtration system rated for the water's salinity level.

Why did my coastal well turn salty after the hurricane even though floodwater never reached my yard or wellhead?¶

A coastal well that stayed completely dry on the surface can turn salty after a storm for two subsurface reasons. First, storm surge flooding low-lying marshes or beaches several hundred meters away can infiltrate the shallow water table and migrate laterally toward your well screen. Second, and very commonly, widespread post-storm groundwater pumping by neighbors (or municipal utilities) lowers the local freshwater table, which causes the deep underlying wedge of dense ocean saltwater to cone upward (saltwater upconing at a 40-to-1 ratio under the Ghyben-Herzberg relation) right into the bottom intake of your deep well.

Can I use a LifeStraw, Sawyer filter, or Brita pitcher to filter salty well water?¶

No, portable camping microfilters (such as LifeStraw or Sawyer hollow-fiber membranes) and activated-carbon pitcher or refrigerator filters (such as Brita or Pur) remove zero dissolved salt from water. Hollow-fiber camping filters have pores measuring 0.1 to 0.2 microns wide to trap bacteria and protozoa, whereas dissolved sodium and chloride ions measure roughly 0.0004 microns, hundreds of times smaller than the filter pores, allowing all salt to pass straight through. Only Reverse Osmosis (RO) membranes (0.0001 microns) or distillation can separate dissolved salt from water.

Why shouldn't I flush chlorinated well water into my septic system after disinfecting my well?¶

Flushing a shock-chlorinated well through indoor sinks or toilets into a private septic system causes two severe problems. First, discharging 2,000 to 5,000 liters (500 to 1,300 gallons) of water in a few hours hydraulically overloads the septic tank and saturated coastal drainfield, forcing raw sewage to back up into the house or wash solid sludge out into the drainfield trenches. Second, dumping hundreds of liters of 200-ppm super-chlorinated water into the septic tank kills the beneficial anaerobic bacteria required to break down solid human waste. Always flush well purge water and shock-chlorinated water outdoors through a garden hose to a safe drainage area at least 15 to 30 meters (50 to 100 feet) away from the septic system.
