Aquarion Water Company: A Look into the Challenges Facing Connecticut’s Largest Water Utility

The Aquarion Water Company (AWC) is Connecticut’s largest water utility (AWC, 2011).  Headquartered in Bridgeport, the company serves more than 580,000 people in 39 cities/towns throughout Connecticut as well as five in Massachusetts and three in New Hampshire (AWC, 2011).  Aquarion’s presence in the public water supply business is impressive.  Established in 1857, it remains “the largest investor-owned water utility in New England and among the seven largest in the U.S” (AWC, 2011).  Despite exhaustive research efforts, Aquarion Water Company’s “Capital Improvement Plan” could not be located.  This may be attributed to the company’s broad scope of operations which involves an abundance of communities across several states.  Detailed information regarding local infrastructure and improvement projects; however, is readily available.  This includes upgrades in various parts of Connecticut including Greenwich, Stoningham/Groton, and Brookfield.  These provide adequate insight into the company’s broad scope of impact in addition to investment and planning challenges posed by infrastructure improvements of the past, present, and future.

While Aquarion’s undergoing capital improvements are colossal and costly, they are absolutely necessary.  Given the scope of service and the amount of infrastructure and equipment involved, the company must satisfy its responsibility to provide a magnitude of customers with an ample supply of clean, potable water.  In consideration of the company’s aging infrastructure, the urgency for capital improvements is a matter of both public health and safety. As such, the replacement of aging infrastructure continues to be an integral part of the company’s capital project work.   Infrastructure improvements and expenditures are extensive, due in part by Aquarion’s recent growth via the acquisition of smaller water utility companies.

Acquisition expenditures resulting from the rehabilitation of a former company’s infrastructure assets are magnanimous.  Since 2008, Aquarion has invested $25 million to upgrade the Putnam Filter Plant in Greenwich, CT.  Following its purchase of Connecticut American Water Company in 2002, Aquarion immediately began prioritizing capital improvements to address critical infrastructure deficiencies.  The urgency was justified as the plant had not undergone any major improvements since the 1950s (AWC, 2011).   From 2002 to 2008, Aquarion invested $6 million to the Putnam facility, the town’s largest source of water, in order to rehabilitate filters, install stand-by power, and upgrade electrical service to ensure a supply of 20 million gallons of water a day for consumption and fire safety (AWC, 2008).  Improvements also included the replacement of a failing 1920s-era treatment clearwell to meet supply demands and comply with health department standards (AWC, 2008).

Aquarion’s responsibilities recently extended to Brookfield’s Greenridge water system.  On November 2, 2011, Connecticut’s Public Utility Regulatory Authority and the Department of Public Health approved Aquarion’s proposal to deliver uncontaminated water to the Greenridge district, whose previous supplier had filed to cease operations.  According to decision drafted by the Connecticut’s Department of Environmental Energy and Protection (DEEP), Aquarion’s estimated total cost for the proposed water main and associated improvements totaled $3.25 million including $564,000 in improvements made by United Water, the previous supplier (DEEP, 2011).  Aquarion also continues to upgrade its infrastructure in the Stonington/Groton, CT area where it began relining the 21 year old, 8-inch water mains at Lords Point this past August (AWC, 2011).  Aquarion’s capital improvements reflect its self-proclaimed commitment to ensuring the quality of its water systems and delivering uninterrupted service.

All across America, drinking water infrastructure is nearing or exceeding its life expectancy and systems are failing.  Connecticut is certainly no exception.  According to a 2008 survey conducted by the American Society of Civil Engineers (ASCE), “Connecticut’s drinking water infrastructure needs an investment of $653 million over the next 20 years” (2010).  Accordingly, Aquarion’s capital improvement spending is expected to considerably increase over the next few years to achieve the timely replacement of problematic water mains, flow-management valves, fire hydrants, meters and leak-detection equipment (AWC, 2011).  Aquarion’s spending has been recently amplified and accelerated due to the acquisition of smaller, less capable utilities starved of the funding necessary to manage, maintain, and replace their aging water infrastructure.  This poses new challenges as Aquarion must familiarize itself with the water main condition so as to facilitate leak detection and prevent breakage.

Buried infrastructure is especially vulnerable as maintenance and repairs are substantially expensive and disruptive.  The closure of a major intersection and a street lane in Bridgeport caused by a water main break on November 17, 2011 is one such example.  According to the Connecticut Post, “the intersection of State Street and Broad Street has experienced three water leaks in the past six weeks,” a clear indication of the challenges posed by the city’s aging infrastructure, comprised of pipes that are 90 years old (2011).  Bruce Silverstone, a company spokesman for Aquarion Water Company, commented:”It’s difficult, a very difficult area because of all the infrastructure that’s underground, there.  It is an unusual situation. When these breaks take place, we must replace them on kind of a piece-meal basis” (Craig, 2011). Since budget restrictions prevent total replacement, the company is combating problems as they arise. Experts argue; however, that “the ‘fix-on failure’ approach is no longer working” (Kinge, 2009).

Aquarion also faces water supply challenges posed by stream flow regulations required to be developed by Section 26-141b of the General Statutes.  Passed in 2005 by the Connecticut General Assembly, the act requires the DEEP to collaborate with the Department of Public Health and stakeholders to “update standards for maintaining minimum flows in rivers and streams” so as to achieve a balance in water usage that respects river and stream ecology, wildlife, and recreation while providing for public health and safety, industry, agriculture, water supply, and other lawful water uses (DEEP, 2011).  While Aquarion recognizes its responsibility for “conservation and natural resource management,” George Logan, its Director of Capital Planning, testified that the proposed regulations “did not adequately provide for public water supply” (Testimony, n.d.).  According to Logan, “more than nine million gallons per day would have been lost, approximately 10% of our total water supply” (Testimony, n.d.).  Company costs would have also been markedly affected, requiring approximately $100 million to modify its facilities, an investment equivalent to 3 years of total capital spending (Testimony, n.d.).  This would divert monetary allocations from necessary infrastructure improvement.  Logan warns that that the investment “would result in an incremental rate increase of approximately 10%, at a time when personal and municipal budgets can least afford to pay it” (Testimony, n.d.).  Added to a lack of infrastructure funding is the elevated price of electricity as Connecticut has the second highest electric rates in the country (McCarthy, 2008).

To finance its capital investments, Aquarion initiated a customer surcharge in April of 2009 which has steadily increased since its inception (AWC, 2011).  The surcharge bill, referred to as Water Infrastructure and Conservation Adjustment (WICA), was approved in 2007 by the Connecticut Legislature to help fund the timely replacement of water distribution pipes and related infrastructure that have either reached the end of their useful life or threaten water quality or service (AWC, 2011).  As of July, 2011, the current WICA surcharge is 0.32% (AWC, 2011).  The company recently applied for a surcharge increase to 0.35% which will take effect on April 1, 2011, if approved (AWC, 2011).  The WICA is subject to change throughout the year pending infrastructure improvements and approval by Connecticut’s Public Utilities Regulatory Authority (AWC, 2011).

In an interview conducted by Global Water Intelligence (GWI), Frank Firlotte, Aquarion’s CEO, justifies the rate increases, attributing them to the company’s rising opex.  According to Firlotte, an excess of $100 million has been invested in Connecticut alone with 40% of the hike related to capital investment, another 40% to escalating operating expenditures, and the remainder to falling volumetric sales (GWI, 2010).  Since Aquarion currently operates on the basis of a 45/55 debt to equity ratio and a Return on Equity (ROE) of approximately 10%, the utility is able to handle additional debt to fund investment in the rate base (GWI, 2010).  Although Firlotte is hopeful that the Connecticut Department of Utility Control will award Aquarion an ROE above 9.75% in favor of his company’s “efficiency,” “service delivery,” and “operational metrics,” he acknowledges that the system of regulation is not based on performance as it is in other countries (GWI, 2010).

The former director of Yorkshire Water in England, Firlotte is frustrated by the reluctance of local government to relinquish water provisions (GWI, 2010).  As the company sets its sites on continued expansion, it must gain appropriate regulatory approval and acquire adequate infrastructure improvement capital.  In the era of failing water infrastructure, Aquarion is destined to encounter an increasingly challenging process.  As a nation that dedicates only 2.4% of its GDP to infrastructure, a continued lack of financial commitment will further compromise capital improvements, the economy, the water supply, and the public health of a bustling American population (ASCE, 2011).  Comprehensive assessment, planning, and funding over time are the most prudent solutions to this pressing issue.

CONSUMERS BEWARE: The Dangers of Endocrine Disruptors (EDCs) & Pharmaceuticals in Personal Care Products

Just when you thought it was safe to drink the water, look no further than your medicine cabinet.  Concerns continue to  build over the public health impact of our water supply.

What are common chemicals/classes of EDCs?

According to the National Institute of Environmental Health Sciences (NIEHS), chemicals/classes of endocrine disruptors include “pharmaceuticals, dioxin and dioxin-like compounds, polychlorinated biphenyls, DDT and other pesticides, and plasticizers such as bisphenols (2011).”  Disturbingly, endocrine disrupting chemicals (EDCs) can be found in literally thousands of common products including plastic bottles, metal food cans, detergents, flame retardants, food, toys, cosmetics, and pesticides (NIEHS, 2011).  The broad presence of EDCs in everyday products increases the likelihood for interference with the body’s endocrine system to produce a number of adverse developmental, reproductive, neurological, and immune effects (NIEHS, 2011).  While the field of endocrine disruption is fairly new, studies are being conducted to confirm whether endocrine disruptor exposure may reduce fertility and increase the incidence of endometriosis and some cancers (NIEHS, 2011).  The future of this field will undoubtedly yield some extraordinary findings to ultimately increase the public’s awareness and impact future manufacturing processes.

How do EDCs get into receiving water bodies?

Endocrine disruptors infiltrate receiving waterways via personal, pharmaceutical, and agricultural applications.  Human activity, residues from pharmaceutical manufacturing and hospitals, illicit drugs, and veterinary drugs contribute a variety of pharmaceuticals and personal care products (PPCPS) to receiving waters in the form of prescription and OTC therapeutic drugs, veterinary medicines, fragrances, cosmetics, sun-screen products, diagnostic agents, and vitamins (EPA, 2010).  Agricultural applications also supply receiving waters with a plethora of chemicals suspected of acting as endocrine disruptors including insecticides, herbicides, fumigants and fungicides (NRDC, 1998).  Individuals supply wastewater treatment plants with PPCPs through excretion, bathing, and disposal of medications into the sewer system and trash (EPA, 2010).  Discarding unused medications and personal care products into the toilet is an irresponsible yet common practice that exacerbates the problem.  Since PPCPs do not easily dissolve or evaporate at typical temperatures and pressures, they can infiltrate soils and aquatic environments with ease (EPA, 2010).  PPCPs that are not broken down and processed by the body or degraded by the environment enter domestic sewers and remain untreated.  PPCPs also have the capacity to penetrate soil and aquatics via sewage, biosolid applications, and irrigation with reclaimed water (EPA, 2010).

Endocrine disruptors are also introduced through spray-drifts, runoff from livestock and pesticides, and leachate from municipal landfills and septic systems (Center for Biological Diversity, n.d.).  The widespread use of steroid hormones in confined animal feeding operations (CAFOs) is of particular concern for the introduction of  endogenous steroids, exogenous compounds,  pharmaceuticals, and anabolic growth promoters like trenbolone and melengestrol  into receiving waters (Kolodziej, n.d).  The potential for CAFOs to elevate the concentration of steroids in watersheds is considerably higher with the occurrence of extreme precipitation.  The presence of synthetic steroid hormones such as trenbolone, melengestrol, and zeranol, used to promote rapid livestock growth, increases when the accumulation of animal wastes is not controlled and a direct pathway for wastes to reach surface waters exists (Kolodziej, n.d.).

Why are EDCs of particular concern to regulators?

Since municipal sewage treatment plants are not equipped for the removal of PPCPs and other unregulated contaminants, the presence of endocrine disrupting chemicals (EDCs) in the watershed poses a number of public health concerns.  While the measure of health risks has yet to be quantified, growing evidence suggests that EDCs can produce adverse health effects in humans, wildlife, fish, or birds including developmental, reproductive, neural, and immune problems (EPA, 2010).  This can adversely affect fish ecology and threaten the survivability of species.  A panel of experts convened by the NIEHS and the National Toxicology Program (NTP) found ‘credible evidence’ for the effect of hormone-like chemicals on test animals’ bodily functions at levels below the ‘no effect levels’ established by traditional testing (EPA, 2010).  There is also substantial research in experimental animals and wildlife associating EDCs with reduced male fertility and number of males born, male organ defects, female reproductive diseases, and increases in mammary, ovarian, and prostate cancers (EPA, 2010).  The storage of endocrine disruptors in fat cells can also have long-term negative health consequences.  Exposures to Bisphenol A and other EDCs with estrogenic activities increase the detrimental health effects of cancer and obesity (EPA, 2010).  The transgenerational effects of EDCs is also a focus of study as NIEHS research has found that fertility defects have been passed to subsequent generations (EPA, 2010).    

With the omnipresence of Bisphenol A (BPA), Di (2-ethylhexyl) phthalate, and phytoestrogens in many common, everyday products, the simultaneous exposure to multiple EDCs elevates concerns (EPA, 2010).  As of 2007, over 100 individual PPCPs have been identified in addition to antibiotics and steroids that have been found in both environmental samples and drinking water.  Simultaneous exposure occurs through one’s diet and the medications and cosmetics used.  Studies are now focusing on the association between EDCs and resistance to antibiotic drugs as well as special scenarios involving fetal exposures (EPA, 2010).  Further studies are warranted to investigate the acute and long term effects of EDCs as it remains a pressing and highly controversial public health issue.

Considerations for regulating EDCs in wastewater and/or receiving water bodies

Prior to designing regulations, policy-makers must consider scientific uncertainties associated with EDCs and their potential health effects in animals and humans.  Stringent regulations must rely on a definitive classification system for endocrine disrupting chemicals so as to implement appropriate restrictive measures.  The regulation process necessitates further research to identify conclusive evidence to considerably minimize the controversy that surrounds this issue.  This will require the expertise of a broad variety of experienced medical scientists and environmental health specialists along with substantial research investment capital and time for further research completion.  The implementation of appropriate regulations should reflect a close collaboration between policy makers, field experts, and the public at large.

Policy makers must also consider the level of vulnerability of the population exposed to EDCs and their potential impacts when implementing regulations.  This can be based on a variety of factors including the average age, diet, occupation, and prevalence of obesity, cancers, and metabolic diseases.  Other factors include the presence of major industries within a relevant geographical area.  Infants, young children, and the elderly are special populations who exhibit increased susceptibility to EDCs due to inferior immune systems.  Special considerations must also be considered for pregnant women and individuals with immune disorders/diseases such as AIDS.  Obese individuals and people suffering from cancer are of particular concern as increased EDCs exposure can manifest or exacerbate symptoms associated with endocrine system abnormalities.  One’s occupation is also a critical factor as manual laborers face increased frequencies and durations of EDC exposure.  The presence of industries and the type of manufacturing processes and chemicals used are especially pertinent when initiating regulatory legislation to decrease the overall prevalence of EDC exposures among workers and citizens in the environment in which they live.  Regulations should therefore reflect all of these factors to minimize the overall risk to any given population.

The potential impacts on businesses should also be considered.  In a fragile American economy, the development of new restrictions would pose increased financial and administrative burdens, threatening the survivability of businesses.  The alteration of manufacturing and agricultural processes to incorporate new raw materials to eliminate or reduce the release of EDCs could pose considerable financial losses.  Similarly, provisions that necessitate wastewater treatment to improve levels of EDCs in effluent discharges or measures to decrease employee exposure could prove to be exceedingly costly.  Also, company management plans for the monitoring of EDCs would necessitate comprehensive recordkeeping and reporting, requiring additional manpower and staff.
